Description
technical field [0001] The invention relates to the field of power supply technology, in particular to a self-power supply device for a low-speed electric vehicle. Background technique [0002] Electric vehicles use batteries as energy sources, and convert electrical energy into mechanical energy through controllers, motors and other components to control the current and change the speed of the vehicle. Electric vehicles are green sunrise industries and one of the seven strategic emerging industries identified by the state. [0003] Electric vehicle adopts storage battery to supply power, and storage battery uses the lead plate that is filled with spongy lead as negative pole, the lead plate that fills up lead dioxide is made positive pole, and makes electrolyte with 22~28% dilute sulfuric acid. During charging, electrical energy is converted into chemical energy, and during discharging, chemical energy is converted into electrical energy. When the battery is being dischar...
