Charger: Plugged into a 120 or 240 VAC household outlet, the charger converts alternating current to direct current to charge the EV batteries.
Batteries: Sealed or flooded, and in an array of possible chemistry types and voltages, the battery bank stores and provides the energy for the vehicle.
Controller: The brains of the propulsion system, the controller adjusts the amount of energy sent to the motor based on input from the throttle potbox.
Potbox: Converts the motion of the throttle pedal into an electrical signal for the controller.
Motor: The brawn of the EV, a DC or AC electric motor converts electrical energy into mechanical energy to move the vehicle.
Transmission: Mounted to the electric motor the same way it would mount to a gasoline engine, the gearbox transfers power and torque to the drive wheels.
Main Contactor: The EV’s main on/off control, this relay is often controlled by a standard key switch.
Instrumentation: The right meters are crucial to keeping tabs on your EV’s performance. Standard are a voltmeter, ammeter, and an amp-hour meter.
Emergency Disconnect: This emergency breaker/switch automatically disconnects the battery bank in the unlikely event of a short circuit. The switch can also be used to manually disconnect the battery bank.
DC/DC Converter: Converts EV battery pack voltage to standard 12 VDC to run common automotive electrical accessories like the windshield wipers and sound system.
