Load Management System (LMS) helps adjust the charging rates across different EV chargers based on the available power. It allows more EV chargers to be installed and optimizes charging time for drivers. With load management, you can:
Charge more
Install maximum vehicle chargers.
Cut costs
Save on electricity and system upgrades.
Protect assets
Safeguard your electrical infrastructure.
Monitor usage
Track power use during busy times.
Charge faster
Reduce charging time for efficient EV operation.
For example, if your electrical panel can provide 80 amps and you have four chargers that each need 40 amps, they could overload the panel if all ran at full capacity. But if they communicate, they can share the available power, ensuring they don’t exceed what’s available.
Dynamic Load Management
In EV charging, software can automate this process. For instance, when a second EV is plugged in, the system automatically adjusts how much power is used.
How it works
Load-sharing EV chargers use two methods to distribute power through local load management:
Equally Distributed Load Sharing
All chargers share the available power equally. For example, with 80 amps available and four chargers, each gets 20 amps. If one charger disconnects, the others get a bit more power.
First In, First Charged Load Sharing
The first charger gets full power while others share the remaining electricity. If one charger is unplugged, its power goes to the next charger.
Are EV Chargers Continuous Loads?
Whether EV chargers are considered continuous loads depends on usage. A continuous load runs for three hours or more. For example, if EVs charge overnight at a home or hotel, they are continuous loads. In places where charging lasts only a few hours, they wouldn’t be.
When adding electric vehicle (EV) chargers to your property, it’s important to manage their power use to stay within the limits of your electrical system.
