Load Management and Demand Response are two terms that we have discussed on the SemaConnect Blog for a while. This software capability is an emerging trend in the EV charging market. But what is load management? And why does it matter? Here is a quick explanation for commercial property managers.
What is load management?
Load management is a software feature that is designed to manage electricity usage and reduce costs. A typical Level 2 EV charging station requires a dedicated, 30amp circuit. However, with SemaConnect Smart Load Management, station owners can program a maximum power level in the station software and choose a power sharing mode to control the level of electricity at each station. The station owner then has the option to save energy and deliver less than the maximum 7.2kW to each vehicle if they choose. For example, at a building with a 25kW capacity, a station owner can program five stations to each charge at a maximum of 5kW. Without load management, this building could only install three stations before exceeding capacity. But with load management, this property can install five stations and serve more EV drivers. These power limits lower the installation costs and the monthly electrical bills to the property.
Why does load management matter?
EV load management is designed for commercial properties that have limited power or budgets. It’s a smart way to reduce either the CapEx or OpEx costs of the charging station program. Some older buildings use load management because their electrical capacity is half the amount needed for their total number of stations. Other times, a developer needs load management because the local building codes requires 50+ stations, and they want to minimize the cost of electrical infrastructure. With load management, an electrician can install multiple stations on the same circuit without exceeding building capacity. It’s easier to install more commercial charging stations at lower costs, helping even more EV drivers charge as needed. It’s a win-win!
As more drivers buy electric cars, they’ll need a place to plug in. Load management helps commercial properties fill this need, without spending thousands of dollars on new electrical infrastructure. It even helps utilities manage the grid.
