An electric vehicle conversion is the modification of a conventional internal combustion engine vehicle (ICEV) to electric propulsion, bike conversion kit is for electric bike,creating an all-electric or plug-in hybrid electric bike.
Almost any vehicle can be converted to electric. Many people prefer to pick a vehicle that is light and aerodynamic in order to maximize distance traveled per battery charge. There must also be adequate room and load capacity for batteries.
The battery pack, which provides a source of electrical power. The most commonly available and affordable batteries are lead-acid flooded type. Next are the AGM (Absorption Glass Mat) sealed maintenance free batteries, a little more powerful and expensive. Then there are the more exotic batteries like Ni-MH and Li-ion; more difficult to find but light and longer lasting, maintenance free, and much more expensive. The new lithium batteries are showing some promise for EVs in the near future.
The charger which restores energy to the batteries (which may be mounted within the vehicle or at a special charging station at some fixed location)
The power controller, which regulates the flow of energy between the battery and the electric motor(s), controlled by an electronic throttle.
One or more electric motors and their mechanical attachment to the driveline
Power conductors connecting the battery, controller, and motor(s)
Accessory equipment to power auxiliary equipment such as power brakes and heating system
Control circuitry and equipment to allow control and interlocking of the various components
Instrumentation specific to the operation and maintenance of the bike conversion kit.
