Electric heavy trucks are energy-saving and environmentally friendly, in line with China's sustainable development strategy, worthy of strong promotion, and are also loved by the majority of drivers. With the popularization of electric heavy trucks, problems such as long charging time and short battery life of electric heavy trucks have emerged.
[0003] This new battery swapping mode is born to solve the charging pain points of electric vehicle users. By directly replacing the battery to replace the traditional charging mode, it effectively solves the problems of slow charging speed, short cruising range, and high initial vehicle purchase cost existing in the actual application of pure electric heavy-duty trucks.
