[0002] Since general ATV models are equipped with small on-board engines, energy conversion is the conversion of internal energy into mechanical energy through the principle of heat engine. The energy utilization rate of the power battery pack is higher than that of the engine, because the power battery pack does not produce exhaust gas and pollutants during the energy conversion process, while the engine will produce a large amount of exhaust gas and pollutants, as well as certain energy losses and noise pollution. However, with the development of new energy, new energy technology has gradually been applied to the field of all-terrain vehicles. The power battery pack is used to provide power to the drive system of the all-terrain vehicle.
