- Jun 06, 2018 -

In general, the old-age scooter is composed of a battery, an electric wheel hub, a controller, and a charger. For Taiwan manufacturers with higher requirements for safety, the overall design is based on the design concept of the vehicle. The vehicle is generally divided into power supply system, front axle, rear axle, controller, and frame.

Because the current cost of lithium is relatively high, most manufacturers use lead-acid batteries. Generally, a group of batteries is composed of multiple 12V batteries connected in series to form a battery pack as a power supply system. According to relevant national regulations, the voltage of electric vehicles must not exceed 48V;

Motor hubs are divided into: brushed toothed high-speed electric wheel hub (referred to as high-speed motor or acoustic motor), brushless toothless low-speed electric wheel hub (referred to as low-speed motor or silent motor) and brushless toothless program motor (referred to as program motor);

According to the control mode, the controller is classified into four types: full-motion type, intelligent type, dual-control type, and non-zero-start type. The control system consists of a main controller, a meter display, a speed control switch, and a brake power switch. Function has stepless speed regulation, brake power failure protection, undervoltage protection and overcurrent protection and other functions; the charger is classified according to the output plug has a lotus plug type, ordinary computer plug type, special computer plug type. Classified according to the charging performance as an ordinary online maintenance charger, fast charge online maintenance charger. According to the charging voltage is classified as 24V, 36V, 48V.
