Embodiment Construction
[0024] The specific implementation manner of the present invention will be described in further detail below by describing the best embodiment with reference to the accompanying drawings.
[0025] The main idea of the present invention is to use the acquisition module to collect data such as voltage, current and temperature of the battery, and then transmit it to the control chip MCU, and estimate the SOC of the battery through the MCU to find out which batteries have the highest or lowest power. When the high and low batteries are adjacent, a signal is given to control the PWM drive circuit to drive the switch array so that the Buck-Boost equalization circuit corresponding to the corresponding battery cell works to achieve balance. If the high and low batteries are not adjacent , the flying capacitor equalization module is driven to work to achieve equalization. specific principle box figure 1 as follows:
