Description
technical field [0001] The invention relates to the field of rechargeable battery management and application, in particular to a wireless charging device for step-by-step utilization of power batteries. Background technique [0002] According to the relevant plan for the development of new energy vehicles, it is estimated that by 2020, the production capacity of pure electric vehicles and plug-in hybrid vehicles will reach 2 million, and the cumulative production and sales will exceed 5 million, using a huge number of power batteries. The performance of the power battery of an electric vehicle will decay as the number of charge and discharge increases. When the battery capacity decays to 80%, it will be decommissioned and is no longer suitable for use in electric vehicles. However, the capacity is very high, and the remaining capacity can be used in stages. in other industries. Wireless charging technology means that it does not need traditional wires to connect to the term...
