WHAT YOU NEED TO KNOW ABOUT EV CHARGING
There are several key factors to selecting the right EV charging solution for your building, including:
+ Understanding the available power in your building and how to future-proof your EV infrastructure
+ Selecting the right EV charger and management software for your needs
+ Installation services including infrastructure, chargers, and site improvements (like signage & painting)
WHAT TYPE OF EV CHARGERS SHOULD WE INSTALL?
EV chargers come in all shapes, sizes, and power ratings. Different chargers are used for different settings depending on several factors. The most efficient option for multi-residential buildings are Level 2 EV chargers. The goal of a Level 2 charger is not to fill up your EV as quickly as possible. Rather, Level 2 chargers will fill up most vehicles within a couple of hours without putting an unreasonable demand for power on your building’s existing electrical infrastructure.
Specifically, a 6.6 kW Level 2 charger will add about 30 km of range for every hour spent charging. If you drive around 50 kmevery day, you can fill up your EV each evening with less than 2 hours of charging.

MULTI-STATION POWER MANAGEMENT
Power management allows your building’s electric infrastructure to support dramatically more EV chargers by adjusting the output of each charger depending on how many EVs are plugged in. Choosing a solution with power management is crucial for future-proofing your building. Below is an example of four 32-amp EV chargers installed on a panel with only 80 amps available. The same principal can be applied across your whole building to quadruple your EV capacity.
POWER MANAGEMENT EXAMPLE
4 chargers, max amperage of 80 A
Two cars plugged in, each charger draws its max amperage of 32 A.
Two more cars plug in. Amperage is dropped so that total power usage remains under 80 A.
As one car finishes charging, power is redistributed to the remaining chargers.
