[0002] Today's electric vehicles (such as electric bicycles, electric motorcycles or cars) are equipped with battery modules and battery management systems, because there are many different types of charging specifications for USB devices on the market, and the maximum charging current required is also different. However, although the battery management system in these electric vehicles has the function of charging the USB device, it often cannot identify the type of the USB device, and can only provide a fixed charging current to charge the connected USB device.
Therefore, the efficiency of traditional battery management system for charging USB devices is not high

Description
technical field [0001] The present invention relates to battery management systems, in particular to battery management systems for electric vehicles such as pedelecs, electric motorcycles or automobiles. Background technique [0002] Today's electric vehicles (such as electric bicycles, electric motorcycles or cars) are equipped with battery modules and battery management systems, because there are many different types of charging specifications for USB devices on the market, and the maximum charging current required is also different. However, although the battery management system in these electric vehicles has the function of charging the USB device, it often cannot identify the type of the USB device, and can only provide a fixed charging current to charge the connected USB device. Therefore, the conventional battery management system is not efficient in charging the USB device. Contents of the invention [0003] The present invention provides a battery management sy...
