Description

technical field [0001] The present invention relates to the technical field of batteries, and more specifically relates to a high-precision battery charging and discharging management system. Background technique [0002] The existing battery management system is generally realized by the battery charge and discharge management module, the power measurement module and the MCU module. The power measurement module transmits the collected voltage, current and power to the MCU, and then estimates the battery SOC after processing by the MCU; through The battery charging and discharging management can be accurately realized by using the battery charging management module and MCU cooperative processing. Such a solution is not only complex in circuit but also high in cost. Moreover, the existing battery management system can only support mains charging or solar charging, and does not have three charging methods: solar, mains and hand generator. As a result, its field of use and ti...
