If the full capability of chargers will be allowed to exceed the panel’s rated capability with ALM, and uncontrolled hundreds on-site will be monitored by the CMS, then chargers will be put in and managed beneath a required electrical restrict.
As fleet electrification positive factors momentum, the well timed and cost-effective set up of charging infrastructure continues to be one of many largest challenges. Fleet managers usually ask, “How can we set up charging infrastructure extra rapidly and affordably?”
One more and more common answer is to keep away from utility improve delays and bills by optimizing using the location’s current electrical infrastructure with the assistance of a cost administration system (CMS).
Why Leverage Current Infrastructure?
Many fleet operators face tight deadlines to deploy infrastructure rapidly to benefit from expiring grants, or to adjust to regulatory deadlines such because the Superior Clear Fleet rule in California. Others might wish to begin the electrification journey with a pilot program at a minimal value to check and study concerning the expertise.
For these and lots of different circumstances, using current electrical infrastructure will be the distinction between an “unattainable web site” and a “possible web site.”
For fleets aiming to deploy a restricted variety of autos, the time and expense related to requesting new utility companies and establishing these upgrades will be overwhelming and pointless. When dealing with tight deployment schedules, ready for a devoted service for EV charging won’t be a viable possibility.
Many websites have already got current 200- to 800-amp panels that may help charging infrastructure when paired with the suitable load administration expertise.
Optimizing Your Current Panel
Two key options of a complicated CMS may also help fleets maximize the charger capability that may be put in on an current panel:
- Automated Load Administration (ALM): This expertise permits the full capability of chargers to exceed the panel’s rated capability by enabling the CMS to strategically share obtainable energy for charging throughout a number of cost ports.
- Website-Built-in Load Administration: The CMS displays constructing vitality hundreds (or different hundreds at a web site) and adjusts charging based mostly on real-time obtainable capability as constructing hundreds fluctuate (e.g., when HVAC programs cycle on and off).
If the full capability of chargers will be allowed to exceed the panel’s rated capability with ALM, and uncontrolled hundreds on-site will be monitored by the CMS, then chargers will be put in and managed beneath a required electrical restrict, even for websites the place constructing hundreds occupy nearly all of panel capability at some hours of the day.
This may usually enable a fleet depot electrification venture supervisor to put in chargers — in compliance with electrical codes — at a web site the place it won’t in any other case be potential.
A Sensible Instance of Load Administration
Think about the next state of affairs:
- A fleet secures a state grant to fund 4 electrical autos.
- The fleet’s storage has an current 100% rated, 400-amp fundamental panel.
- Electrical load calculations point out that the panel has no obtainable capability.
- Nevertheless, the precise in a single day load is considerably under capability, roughly 100 amps.
- To make sure every car can full its route, 4 19.2 kW 80-amp AC chargers are beneficial.
- Modeling reveals that to fulfill charging wants for the 4 routes, the CMS can be certain that the full draw won’t ever exceed 250 amps and that each one autos may have loads of time to get a full cost for the day.
- Through the use of ALM and site-integrated load administration, the fleet is ready to safely set up 4 chargers with mixed complete capability of 320 amps on the present panel, and meet its funding deadline.
With out the mixed automated and site-integrated load administration capabilities of the CMS, this case would necessitate a service improve or a brand new service to help extra charging.
Nevertheless, by using each ALM and site-integrated load administration, this fleet can current a possible, secure, and efficient plan to their utility and native allowing authority. This method permits them to put in all 4 chargers instantly, adjust to the Nationwide Electrical Code, proceed with the deliberate pilot program, and retain their grant funding.

Overcoming Infrastructure Challenges
Leveraging current electrical infrastructure for fleet electrification not solely saves money and time but in addition opens new alternatives for fleet operators to deploy electrical autos at tough websites with out pointless delays.
With the proper CMS, fleets can overcome infrastructure challenges and transfer ahead confidently with their electrification plans.
