EV Charging 101
Unlike gasoline, which is dispensed at centralized stations, electricity is available almost everywhere—so EVs are typically charged where they’re parked. Since cars are parked most of the time, charging at home or work is ideal. This allows EV drivers to integrate charging into their everyday lifestyles and routines.
Benefits to property owners:
1) Attracts and retains residents
2) Can increase property value
3) Supports sustainability goals
EV Charging Levels – What Works for Multifamily?
There are three levels of electric vehicle charging, Level 1 (L1), Level 2 (L2), and Direct Current Fast Charging (DCFC).
L1 and L2 charging are the best options for multifamily properties and the on-site user. DCFC is not recommended.
EV Charging Levels Explained
Level 1 (L1) charging equipment provides charging through a common 120-volt (120V) alternating current (AC) wall outlet. A 20-amp circuit is standard. Charging an EV to 80% from empty on a L1 charger/outlet (120V) typically takes 30 to 50 hours, depending on battery size, vehicle settings, and circuit breaker components.
Level 2 (L2) charging equipment offers higher power AC charging speeds through 208/240 volt AC circuitry. Charging an EV to 80% from empty on a L2 charger/outlet typically takes 4 to 10 hours, depending on battery size and charger power output. This is the most common charging level for apartments where EVs will be parked overnight
EV Readiness
EV readiness prepares a property to provide EV charging by including EV charging infrastructure in development or building renovations.
There are three different types of EV charging spaces: EV-capable, EV-ready, and EV supply equipment (EVSE)-installed.
EV-Capable: Parking spaces have panel capacity and conduit to the parking space. The parking space is “capable” of being upgraded with circuit breaker, wiring, and receptacle/junction box (J-box) or EVSE at a later time without panel upgrades.
EV-Ready: Parking spades have panel capacity, an installed breaker, wiring, and conduit, terminating in a receptacle or junction box.
EVSE-Installed or EV-Charger Installed: Parking spaces have an EV charger or EV smart charging outlet installed.
