组成部分

component

Generally, the old scooter is composed of four parts of the battery, the electric wheel hub, the controller and the charger, and the body part. For Taiwan manufacturers with higher safety requirements, the overall design is based on the design concept of the car. The whole vehicle is generally divided into power supply system, front axle, rear axle, controller, and frame.

Because the current cost of lithium battery is relatively high, the general manufacturers use lead-acid batteries. Generally, a group of batteries are connected in series by a plurality of 12V batteries into a battery pack as a power supply system. According to relevant national regulations, the voltage of electric vehicles shall not exceed 48V;

The motor hub is divided into: a brushed toothed high speed electric wheel hub (referred to as a high speed motor or a sound motor), a brushless toothless low speed electric wheel hub (referred to as a low speed motor or a silent motor), and a brushless toothless program motor (referred to as a program motor);
