Description
technical field [0001] The present application relates to the field of power battery modules, in particular to a power supply system and a charging and discharging method. Background technique [0002] In the existing technology, in order to solve the problems of battery life anxiety and slow charging of electric vehicles, electric vehicles are usually equipped with high-voltage platform technology and supporting super charging piles. However, charging piles are generally unable to support charging on 800V platforms. Therefore, in the early design and development stage, it is necessary to consider compatibility with charging piles on 400V platforms, and to complete the iterative upgrade of technology through a smooth transition. Contents of the invention [0003] In view of this, the present application provides a power supply system and a charging and discharging method, which are compatible with various charging piles and realize switching between different charging and ...
