KART ELECTRICAL AND CONTROL SYSTEM

The principal elements of the electrical drive system are the DC battery motor controller, the DC electric motors and the rechargeable lead-acid batteries. In addition the motor speed controller requires low power speed "demand" signals (from the accelerator potentiometer). There is also an on/off switch, a reverse switch and optionally a battery condition monitor to let you see the stage of charge of the batteries. The DC battery motor controller is at the heart of the system - it takes the fixed nominal 24V from the battery pack and outputs a variable 0 to 24V to the motors. This delivers the kart's variable speed. By reversing the polarity to the electric motor the speed controller also provides the reverse drive. The motor controller suggested in the plans can be substituted by other similar current rated DC battery motor controllers - you choose.

The 24V 250W DC electric motors are commonly available as electric scooter spares and are easily mounted and connected to the drive transmission by roller chain.

Standard sized rechargeable lead acid batteries are used. These are manufactured by a large range of suppliers and can provide several hundred charge cycles during their lifetime. You'll also need a good multi-mode battery charger to keep the batteries in good condition.
