Problems solved by technology
At present, when charging the battery system of new energy vehicles, because the charging current is limited by electrical components such as high-voltage relays in the charging circuit, the charging circuit cannot transmit a high charging current. The charging current is limited, which leads to the inability to further shorten the charging time of the battery system and limits the improvement of charging efficiency.

The invention provides a battery charging method, device and system. The method is applied to a high-voltage distributing assembly, wherein the high-voltage distributing assembly is connected with a battery management system; the high-voltage distributing assembly is further connected with a to-be-charged battery; a plurality of battery modules which are connected in parallel are arranged in the battery; and the high-voltage distributing assembly is used for switching connection modes between the battery modules. The method comprises the steps of receiving a switching signal transmitted by thebattery management system; switching the parallel connecting mode of the battery module into a serial connecting mode on the basis of the switching signal; and receiving a modular rapid charging signal transmitted by the battery management system to charge the battery through a peripheral power supply. The time consumed for charging the battery can be shortened effectively, and therefore, the battery charging efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a battery charging method, device and system. Background technique [0002] New energy vehicles are the development trend of future travel tools. New energy vehicles are equipped with a battery system for charging the vehicle. Before using the battery system to charge the vehicle, the battery system needs to be charged. At present, when charging the battery system of new energy vehicles, because the charging current is limited by electrical components such as high-voltage relays in the charging circuit, the charging circuit cannot transmit a high charging current. The charging current is limited, which leads to the inability to further shorten the charging time of the battery system and limits the improvement of charging efficiency. Contents of the invention [0003] In view of this, the object of the present invention is to provide a battery charging method, devic...
