Description
technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to performance testing and maintenance equipment for battery packs of electric vehicles. Background technique [0002] Saving oil and reducing emissions, reducing greenhouse gas emissions and air quality purification are the three major challenges facing the automotive industry in the world today. To meet the challenge, the world's major automobile companies are developing electric vehicles. The battery provides electric energy for the driving motor of the electric vehicle, and the electric motor converts the electric energy of the power supply into mechanical energy, and drives the wheels and working devices through the transmission or directly. Electric vehicles themselves do not emit harmful gases that pollute the atmosphere. Even if the power consumption is converted to power plant emissions, except for sulfur and particles, other pollutants are also signi...
