Description

Technical field: [0001] The invention relates to a power device for an electric vehicle, in particular to a power compensation energy storage device for an electric vehicle. Background technique: [0002] An electric vehicle is a device that uses a battery as an electric energy source to drive a DC motor to make it walk. It has the advantages of environmental protection and energy saving and has attracted more and more people's attention and popularity. However, due to the small capacity of the battery as a power source , large volume, and heavy weight, and when an electric vehicle is started, that is, from the start to the predetermined speed, a large current is required. If the discharge exceeds 50% of the rated value, it will be regarded as a destructive discharge, resulting in a sharp drop in the capacitance of the battery. Not only does it start The large electricity makes the battery life of the electric vehicle greatly reduced, and the battery life will be greatly sho...
