Workplace Charging Facts: Announcing Results from our pilot with…

Look at all the cars parked at your office or warehouse parking lot. Now imagine 20, 50, 100% of them are electric. And imagine that it’s your job to make sure they are charged. This is not sci-fi, it is already the reality in several states and counties and almost inevitably in most of them within ten years.

When you need dozens or hundreds of chargers in your parking lot – how do you get power for all of them? How do you get enough energy? How do you balance your resources so you can get the infrastructure and the energy cost-effectively? Most importantly – how do you do it such that no driver gets stuck, and no one has to waste time at public charging or getting out in the middle of the day to move cars on / off the chargers?

This was the subject of the pilot and study we ran with Hertz Israel’s leasing business this year, which has now concluded successfully. We built a microgrid-enabled, scalable managed charging facility that integrated grid and solar electricity and ran it with drivers for four months. We collected data about driver and charging behavior, ranges and issues, power and energy output, infrastructure and energy costs and optimized the system for different scenarios.

We will be posting some of the learnings here, but if you want to learn more – contact us to discuss best practices for fleet / workplace charging.

EV Fleets Need Smart Charging, NOT Fast Charging

Why it matters:

Because focusing on fast charging will cost you millions, delay your electrification – and it won’t solve the problem of electrification at scale.

 You do NOT need the fastest chargers.

The Big Picture

Yes, we really want EVs to be just like ICE vehicles – when the gas runs out, you stop for 5 minutes, take a bathroom break, and drive on. But they aren’t, and won’t be anytime soon (more on that below). For the next decade or more, every stop is going to take 30 minutes, 40 minutes, maybe hours. So the question is not “what can I buy to make the stops the fastest”, but rather “how can I charge the vehicles when they would have been stopped anyway”.

It’s not “how can I charge the fastest”, it’s “how can I charge when the vehicles are parked anyway”

For consumers lucky enough to have their own garage – this means charging their car when they’re sleeping. Plain and simple. But if you have to charge a fleet of vehicles, you need to charge a lot of vehicles at the same time. Well, guess what? Your utility limits your power and won’t let you run many fast chargers concurrently – even if you wanted to (and you shouldn’t). And if you only have a few of those – it means you need drivers moving vehicles around all night.

 In 99.9% of cases you can’t install many fast chargers even if you wanted to.

So the right solution is Smart Charging, where you have many vehicles connected to many chargers, and what moves around is the electricity – NOT the vehicles. What you want is a system that can split the power between your vehicles in an intelligent way – based on what they need, when they are leaving and where they are going. Such a system can manage the power draw, keeping it within limits, thus making it cheaper to install and operate your facility. It also manages charging speed so vehicle batteries stay healthy, and minimizes the amount of moving vehicles around needed – so that you waste less driver hours.

Smart Charging charges many EVs concurrently, optimizing power to fit the vehicles’ needs and the energy available.

Wait A Minute, So What’s The Problem With Fast Charging?

First, what we call “fast” charging is actually slow compared to refueling. Batteries are NOT fuel tanks. Physics dictates that pushing electrons into them too fast affects the materials, creating heat and deformation. Charge fast and you degrade your battery quickly. Charge too fast and it will catch fire. The on-board software in the vehicle will limit charging speed to what the battery can take – regardless of the fast charger output.

Battery technology does NOT change very fast. The batteries that will be installed in vehicles sold over the next 5-10 years will, at best, take 20-30 minutes to “fast” charge and if you do that too often they will degrade very quickly. And even 30 minutes is too long to just stop at an EV charging station every 300 miles. Think of the driver time overhead. Consider how many vehicles need to fit into a “station” at once.

So – the right thing is to charge your vehicles when and where they are already stopped.

You need dedicated chargers – in your parking lot.

Once you realize that it’s about charging the vehicles where and when they stand already – what you want is as many chargers as possible. So the driver dropping off just connects and leaves. For most fleets that means overnight charging. This allows you to charge slowly. How slow depends on how much your vehicles drive per day. But for most fleets Level 2 AC charging is fine, 99% of the time.

Unless your vehicles go hundreds of miles per day – Level 2 is fine.

So why does it have to be smart? This is where power constraints come in. If you try to put in a lot of chargers (that means a lot of “slow” chargers or a few “fast” chargers) you will quickly find out that your utility will take years to get you the service upgrade you need. Smart charging means that there is a system that manages the power such that you can stay within the boundaries of what you have – through a combination of scheduling / staggering when each vehicle is charged, and the use of additional resources like energy storage (batteries), solar or other power generation.

My vendor says the chargers are smart. Is that enough?

Every AC charger that can be controlled remotely (e.g. via cellular, WiFi etc.) is marketed as “smart”. But just because a charger can be controlled, it doesn’t make it smart. The intelligence resides in the software system that tells these chargers what to do, not in the chargers themselves. A smart charging system needs to know everything – which are your vehicles, how much energy they need (i.e. how far do they need to go tomorrow?), what are your sources of energy, what are the power limits and the costs per kWh, which chargers you have and what is connected to them.

Only a system that has all this information can make smart decisions regarding which vehicle to charge when and how much – and how to manage the energy and power at your disposal. We sometimes describe this as “air traffic control for charging” – you need to know who is where, what they need, and how to get it to them and direct the vehicles and the energy correctly.

Smart charging manages your EVs, your energy and your chargers in one place. We call it “Air Traffic Control for Depots”

So what are fast chargers good for?

In a site that is designed thoughtfully, a couple of fast DC chargers can handle the exceptions – those vehicles that did not have enough time to charge, because they got there late / had to leave early / weren’t connected in time – and by fast charging you can make sure they are ready for their missions the next day. Remember – fast charger costs 10 to 100 times more than a level 2 charger. Unless you’re powering class 8 trucks or large transit buses – you probably don’t need many of these.

Why is this so complicated?

Change is hard, and folks (and that include fleet managers) want things to be as they are.

But EVs are different from ICE, and if we are serious about decarbonizing transportation, we need to learn to operate them. The good news is that smart charging software systems coupled with well designed charging infrastructure operate intelligently automatically – taking the complexity out of the system. When we build it right, it’s as simple as park, connect, leave. The software will take care of the rest.

Shameless plug:

Port OS is a smart charging system that is built to do all of this and more.

The 6 EV Charging Facts Every CRE Player Needs…

So you’re a commercial real estate owner or developer and the year is 2023. The Biden administration passed the IRA last year and the IIJA two years ago. States like California and New York are passing legislation to effectively ban non-electric vehicles, gas is over $4 a gallon, and Tesla is the most valuable car manufacturer on the planet. Likely as not, you know that your tenants are going to be replacing their gas-guzzlers with electric vehicles in the coming decade. Someone’s probably already hinted that you better start looking at putting EV chargers in your parking lot and solar panels on your roof.. But why? And how? And when? After all, you don’t have a gas pump there now, do you?

Well, electric vehicles are different from gas-powered ones, and electricity is different from gasoline. All that can work in your benefit, or to your detriment. And whether you are in multi-unit housing, retail or logistics, here’s what you need to know as you embark on your journey from CRE player to CRE and Infrastructure player.

The short story is:

  • Your tenants are getting EVs
  • EVs can and should be charged on your property
  • That amenity can make you good money
  • But it requires more than just planting EV chargers and hooking them up
  • To maximize your opportunity and create great service – you will need a “microgrid”, but the government will foot much of the bill
  • And to run it efficiently, you will need a software partner

Now let’s get to the brass tacks.

Your Tenants Are Getting EVs And Need To Charge Them

Whether you own residential units, offices, retail or logistics centers, your tenants are in the process of electrifying their transportation. If they are currently driving passenger cars, they are already eyeing a glitzy Tesla or an economical Chevy Bolt. If they are shipping parcels or dispatching technicians, they may be looking at the Rivian Prime van or the Ford F-150 Lightning. And if they are hauling containers across great distances, someone is already crunching the numbers on a Tesla Semi or Volvo VNR. Lighter vehicles will likely be replaced first, but both market forces and government sticks and carrots (e.g. the Inflation Reduction Act and the Advanced Clean Fleet regulations) are driving this transition for all fleets. Legislation has or is being passed over the country to ban the sales of virtually all fossil fuel vehicles by 2035. But the transition is occurring now, as consumers and fleets realize the practical and climate benefits of this technology, and want to grab the government incentives before they run out. And frankly, so should you!

Your Tenants Will Want To Charge On Your Property

Once they have them, your tenants will need to charge these vehicles. But charging is very different from refueling. Stopping at a gas station, or fueling at a depot only takes a few minutes. Charging a vehicle from empty, whether using Level 2 (“slow”) AC charging or Level 3 DC “Fast Charging”, takes between 30 minutes to hours. For that reason charging at home or a place of work is the best option for most passenger cars, and charging at the depot / terminal / warehouse is the least disruptive option for most delivery vans and trucks. This fact will not change for decades to come. EVs are not smartphones, batteries are not computer chips that double in speed every two years, and vehicles are not replaced with better versions every other year like smartphones.

This means that tenants prefer charging where their cars and trucks are parked anyway. And if you can provide them the facilities and the energy there – chargers and electricity, then you are providing a much needed new service, which you can profit off of. In fact, for many tenants in the future this will become a must-have amenity. Delivery fleets will not be able to operate if the vans can’t be charged at night on the premises. Residents will not rent an apartment if they have to park the car a mile from home twice a week to charge it. Truckers will prefer routes where the truck can be charged while it is being unloaded because otherwise they will lose time and money, etc.

Charging will be a must-have amenity. 

Charging Can Make You Good Money

This amenity replaces an existing expense – gas. Consumers and businesses spend trillions of dollars on gas and diesel, and this spending will be replaced by paying for electricity. It’s a service you can and should charge your tenants for, and as will be explained below – can be both highly profitable and relatively predictable. Your goal should be to be able to provide as much of this electricity as will be needed, which will require new infrastructure as described below.

Your goal should be to provide as much of your tenants charging needs as possible

From your tenants’ perspective, time is money. Time spent driving to a public charging station (if one exists) waiting and driving back is an unacceptable price to pay. Therefore they are a captive audience – if you have the charging equipment and power they need, they will pay a premium to charge on the premises. This means that your ability to provide the power effectively – a good customer experience for a consumer or an effective, manageable and time-saving service to a business customer, will make your customers happier and you richer.

To do so effectively and profitably, you will need to be able to provide a lot of power, when and where your tenants need it, and with as little hassle as possible. That requires new electrical infrastructure that goes beyond just sticking on some chargers and hooking them up to the electric panel.

Sticking Chargers In The Ground Is Not Enough

Close but no cigar…

You Need More Electricity At A Lower Cost

Let’s say your tenant has 20 vans to charge at night, and let’s assume you provide level 2 (“slow”) chargers at ~10 kW each. We are looking at about 20 x 10 = 200 kW of power that are needed during those hours with slow charging, and much more if you provide fast charging. For comparison – even this little fleet needs the amount of power required to run 60 homes or a 100 room hotel. If you have many residential tenants with EVs, or commercial tenants with medium to large fleets, you may need a lot more power.

Getting your local utility to commit to install this amount of power and actually deliver it could take years. Add fast chargers, more or larger vehicles, and the conclusion is that it’s not as simple as getting chargers and hooking them up. If you want this to work, you will need to be able to aggregate power, optimize how it’s used, and you will also want to get it cheaply. This introduces new elements to the infrastructure – beyond just chargers. You will probably want to add solar, because almost regardless of where your property is located, solar is the cheapest way to generate electricity – cheaper than buying it from a utility (factoring in the CAPEX, operating costs, and yes – the government incentives).

Solar frees you to some degree from dependence on the utility, and the numbers are quite convincing – especially if you can sell the electricity you generate at a premium, which you absolutely should be able to.

Another element you will most likely benefit from is stationary storage, typically batteries. Storage is useful in a number of ways. First, it lets you take cheap electricity – electricity generated during the day using your solar panels, and electricity bought from the utility during off-peak hours, and use it when you need more of it – whether it’s peak hours (so you avoid paying the higher peak tariffs), or when your tenants are charging most of their vehicles. This allows you to enable them to charge more vehicles at once than the power the utility provides you – because you can add the utility power to the power you extract from your storage. So for instance if your tenants drive all day and charge at night, you can collect cheap solar and off-peak grid power all day, and then use both the electricity in your battery and utility power in parallel to charge many more vehicles at the same time – at night.

Another function of battery storage is improving power quality. For some applications, for instance in manufacturing, even small spikes in power delivery can do a lot of damage. If you have tenants like that, most likely they will require these and benefit greatly from this kind of infrastructure.

And on top of solar and storage, you may want or need to provide back-up generators (gas, diesel), for instance for utility black-outs. This is especially needed if your tenants have fleets that need to continue operation during emergencies – e.g. technicians, first responders etc.

These energy resources that you control to generate or store electricity are offered referred to as Distributed Energy Resources (DER) that are installed “behind-the-meter”. Another term typically used is a “micro-grid”. It’s a grid that can operate independently of the utility grid.

Be The Master of Your Microgrid

When you have a microgrid, you can optimize your energy assets for your tenants’ use. For instance, you can prioritize resilience, by trying to keep your storage battery as full as you can so there is always power in case of an outage. In that case you charge it fully whenever possible. Alternatively you can optimize for costs, trying to only buy electricity from the grid when it’s cheap (e.g. in the morning), and when you have more than you need and the tariff is high – sell it back to the utility for a profit. Or you can try to strike a balance between these approaches, or even have a different policy every day depending on your tenant’s fleets behaviors, the season etc.

A microgrid controller is a computer system that monitors all of the elements in your microgrid and controls their actions. A microgrid management system, the software that manages the controller, allows you to monitor and control your system, implement policies, track equipment usage over time, create reports for analysis, financial reporting and billing and more. It’s the brain that ties your energy system together, allows you to understand what’s happening and respond / plan effectively. Most microgrid controllers will also allow you to control equipment from different vendors. For instance you may buy chargers from one company, storage from another and a generator from a third. A controller that can manage all of them is critical for interoperability. Planning, optimizing and controlling your energy resources is a critical part of giving your tenants good service – and optimizing the profit from these new assets.

Managing Your Charging Assets Requires Advanced Software

OK, so you got the power assets, and you got the chargers. Your tenants have vehicles, but they also have their particular needs and schedules. These may be relatively simple if it’s just consumers (e.g. residential tenants, office-building workers) or quite complex if they are managed fleets like delivery or transportation fleets. They will have particular times they want to charge at and have the vehicles ready at, they may need to be able to prioritize particular vehicles according to their missions or who’s driving them, and so forth. Again – charging takes time, and therefore you can’t necessarily simply adopt a “first-come-first-serve” policy.

If your tenants are simply residential or office workers, you are losing money and goodwill  if some of them are denied and need to drive somewhere else to look for public charging because they need a full battery tomorrow morning. You may want to have different priorities and pricing, e.g. monthly chargers get priority access and bulk pricing. You may want to restrict charging by guests, or enable reception to allow it. You may want to charge the tenant who’s hosting the guest (like “validating parking”) and so on and so forth. There will be different requirements, and you will want to be able to easily identify the vehicles, associate them with the tenants, and apply your policies – all based on your available energy and charging resources.

If your tenants are commercial and their fleet activities are critical and scheduled, there will be more integration required, such that vehicles that need to be ready at particular times can get priority at these times – reserving a charger, reserving energy and so on. These services carry a premium, and they require integrating tenant systems data (e.g. from their fleet management system) with your charging system control. This article can provide you more perspective on what fleet managers need from their charging infrastructure.

These needs mean that to optimize the value from your energy assets, you will need a software system that has the ability to accommodate these different charging schemes, pricing and billing schemes, tenants’ fleet information system and your facility management systems. Such a system works best if it is directly integrated with all of your energy assets – your chargers as well as your microgrid assets. Integrating systems from separate providers can be a losing battle. The system you use should be able to manage your physical hardware that was probably sourced from different vendors, and create interoperability between different vendors’ equipment. That is a critical requirement in the long term, as you may want to expand, upgrade and replace components over the decades that these assets are useful for. Being tied to a specific vendor could become very restrictive over time.

Electrification – It’s Your Long Term Growth Play

Electrification is the name of the game for the decades to come. The combination of climate-change regulation with the improvement in the quality and cost of the assets – from vehicles to solar panels, means these assets are a great add-on to your real-estate portfolio. But to optimize utilization and profit you need to have a whole system built, operated and maintained. That system should serve your tenants’ evolving needs, and grow with them as they go through the process of transitioning their vehicles to electric over the coming decade. Having a strong partner by your side, that is able to assist in planning, operating and expanding your systems while optimizing the financial and energy yield is paramount to getting your dollar’s worth. You can choose to be a leader and corner the market, or you can choose to be a laggard. More about why it makes sense to get in early in a subsequent article.
