EV Charging Installation and Infrastructure

EV Charging Installation and Infrastructure

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.

EV CHARGER MANAGEMENT

The electric vehicle charging experience for both property managers and multi-family residents is defined by EV charger management services, sometimes called “network management”. This includes software and services bundled with EV chargers that are tailored to the needs of property managers and EV drivers.

metroEV supports both types of multi-family charging: community charging, where EV chargers are installed in visitor parking spots to be shared by multiple residents; and dedicated charging, where each resident gets their own EV charger in their private parking space.

Our exclusive provider of charger management software is ChargeLab. We’ve chosen to work with this Canadian supplier because of the flexibility and convenience of their platform. For multi-family buildings like yours, ChargeLab’s EV charger management platform offers these key features:

1. Access control
Control who can access each charger

2. Reporting
Monitor charger usage & generate reports

3. Billing
Bill residents for the electricity they use

4. Technical support
Help setting up & managing your EV charging program

5. Power management
Share power across chargers to support more EVs
