Description
technical field [0001] The embodiments of the present invention relate to the technical field of electric vehicle charging and swapping, and in particular, to a charging system and method for a swapping battery. Background technique [0002] The energy supply method of new energy vehicles includes charging and battery replacement. Compared with the charging method, the battery replacement method has the characteristics of fast energy supply, slow battery attenuation, and little influence of the battery charging capacity on the ambient temperature. [0003] In the prior art, when the battery is charged at the battery exchange station, the battery management system BMS inside the battery exchange battery controls the charger to manage the charging of the battery. When the battery management system detects that the rechargeable battery is fully charged, then End the charging process. However, the charging control method in the prior art is relatively simple, and does not consi...
