Abstract

The invention provides a battery charger which comprises a shell, a voltage controller, a charging unit and a magnetism fixing device. The voltage controller is arranged inside the shell and used for providing direct current charging voltages needed by battery charging for a battery. The charging unit is used for transmitting the direct current charging voltages to a first electrode assembly of the battery. The magnetism fixing device is used for enabling the battery and the battery charger to be fixed in a magnetic connection mode so that the charging unit and the first electrode assembly of the battery can be connected. Compared with the prior art, the battery and the battery charger can be fixed through magnetic connection, and the charging unit can be exposed out of the shell to be arranged. Therefore, the battery charger can be suitable for batteries of different types, and universality is improved. Further, the battery and the battery charger are fixed in the magnetic connection mode in the charging process, the battery charger is prevented from squeezing the battery, and the service life of the battery is prolonged.

Description

technical field [0001] The present application relates to the technical field of charging equipment, in particular to a battery charger. Background technique [0002] The battery charger is a static converter device that uses power electronic semiconductor devices to convert alternating current with constant voltage and frequency into direct current to complete the charging operation of the battery. [0003] At present, when the commonly used battery charger charges the battery, the battery is first put into the casing, and then the battery is fixed by mechanical clamping, and the electrodes on the electrode holder are moved to align the electrodes with the battery during the fixing process of the battery. The electrodes, and finally connect the battery charger to the power supply to charge the battery. [0004] Although the battery charger can charge the battery, the housing of the battery charger needs to be adapted to the size of the battery, which reduces the versatilit...
