Document Type and Number:
WIPO Patent Application WO/2014/186990
Kind Code:
A1
Abstract:
A battery charging and discharging circuit comprises a power supply, a charging branch circuit (21), a discharging branch circuit (22), and a protective branch circuit (23). The battery charging and discharging circuit does not use an energy consumption element, and accordingly, the working efficiency of the whole battery charging and discharging circuit is improved, and it is not easy to cause the problem of heat dissipation, and high-capacity batteries can be simultaneously charged and discharged when multiple charging and discharge circuits are connected in parallel. In addition, short circuit or damage of a signal device does not cause the overall failure of the charging and discharging circuit.
