All-electric (or battery electric) vehicles have an electric motor and an internal combustion engine. The electric motor is powered by a large traction batteries pack. To charge the battery, it must be plugged directly into a wall socket or electric car portable charger. Also known as electric vehicle supply electronics (EVSE). The vehicle does not emit exhaust from the tailpipe because it is powered by electricity.
Key Components In An All-Electric Car
Battery (All-Electric Auxiliary):An electric drive vehicle’s auxiliary battery supplies electricity to power the accessories.
Charge Port: This charging port allows the vehicle to connect to external power supplies to charge the traction batteries.
DC Conversion: This device transforms the DC power from traction battery packs to lower-voltage DC to charge the auxiliary battery and run accessories.
Motor For Electric Traction: Drives the vehicle’s wheels using power from its traction battery. Motor generators can perform both the drive function and the regeneration function in some vehicles.
The Onboard Charger: Receives the AC power from the charge port and converts it to DC energy for charging the traction battery. It communicates also with the charging equipment.
The Power Electronics Controller: Manages the flow of electric energy delivered by the Traction Battery. This unit controls both the speed and the torque produced.
Temperature Control (Cooling): This system regulates the operating temperatures of the engine, power electronics and other components.
Traction Pack: Stores electric current for the electric traction engine.
Transmission Electric: To drive the wheels, the transmission transfers mechanical energy from the electric tractor motor.
Charging Plug-In Electric Vehicles At Your Home
Most drivers of plug-in electric vehicles, which include all-electric vehicles (EVs), and plug-in hybrid cars (PHEVs), recharge their vehicles overnight at their home using AC Level 1. Even though residential equipment is usually installed in garages for safety reasons, outdoor installation and use can be done safely, even if the vehicle has been charged in the rain. Outdoor installations require outdoor-rated equipment for charging. Charging at a multifamily resident complex is more like public charging than charging at your single-family home.
Installing Charging Devices In Your Home
Many owners of electric vehicles will be able to recharge their batteries overnight, with no additional cost. If a dedicated branch circuit power outlet is located near their parking spot, they will be able to meet their daily driving requirements. Level 2 equipment is possible for drivers with shorter commutes or less regular driving schedules. The cost of charging equipment may be offset by state and utility subsidies
The basic Level 2 products include standard safety features such as status lights and warning lights. Smarter Level 2 products feature advanced features, such as data collection systems, user interfaces, enhanced displays and charging timers.
Electricians can check if a homeowner’s home has enough electrical capacity to charge a vehicle. Some homes may be too small to accommodate Level2 charging. However, some homeowners might have an electrician install the circuits necessary to charge Level 2.
Complying With Regulations
All equipment charging devices must adhere to the applicable codes and regulations at all levels: local, state and national. A permit may be required by the local building or permitting authorities.
