Abstract

The invention discloses a battery module including a rechargeable battery, a charging circuit for the rechargeable battery; and a switch adapted to connect the rechargeable battery to the charging circuit, or to output terminals of the battery system. The switch is adapted to change its switching status by a voltage applied to input terminals of the charging circuit. By de-centralizing the controlof the switches in multiple battery modules, adding or removing a battery module from the group of battery modules becomes easy.

Description

[0001] field of invention [0002] The present invention relates to an electrical energy storage device, and in particular to a battery and its connection to a charging circuit. Background technique [0003] Rechargeable batteries are widely used in many aspects of people's lives, such as vehicles, power tools, toys, personal communication devices and so on. Generally speaking, when the battery is an integrated part of an electrical appliance, a charging circuit should be configured for the battery so that whenever there is an external power source (such as grid power), the electrical appliance can be powered by the external power source at this time. Charge the battery. It is also common to configure multiple battery modules for a single appliance to be able to meet demands for higher voltages or higher currents that cannot be supplied by a single battery module. [0004] However, there are some problems with simultaneous charging of batteries / cells for multiple battery mod...
