the utility model relates to a battery module 1, which is formed by connecting a plurality of batteries in series, wherein the voltage of a single battery is set to 3-5V/or 9-13V, the voltage of the battery module 1 is set to 9-15V/or 23-25V, wherein the battery module 1 is used for integrally supplying power, the voltage coordination control of each aspect is carried out by a control board 2, a monitoring control circuit matched with an equalizing module 3 and the equalizing module is matched with the equalizing module (the circuit principle belongs to the prior art and is not described in detail herein), two groups of output ports are electrically connected on the battery module 1, one group of the output ports is 11-14V, the output port 4 is the middle voltage of the battery module 1, the output port 4 of 11-14V can be the middle voltage of any two ends of the battery module 1, after a user uses a car with the output port 4 of 11-14V as a 12V accumulator bottle to perform emergency ignition, when the voltage of one group of batteries 11 in the terminals of the 11-14V output port 4 is lower than that of the other group of batteries 11, and when the monitoring control circuit on the control board 2 monitors that the voltage of one group of batteries is lower, the equalization module 3 automatically starts to store the electric quantity in the high-voltage batteries 11 in the inductor on the control board 2 and then charges the low-voltage batteries 11 through the inductor, and when the voltage of the low-voltage batteries 11 and the other batteries 11 are balanced and then are averaged, the equalization module 3 automatically stops working and enters a sleep mode (the multi-group battery voltage equalization technology is a battery cell balancer with a lossless induction structure based on the ETA proprietary technology, when the voltage difference between the two or two groups of batteries is detected during the operation, if the difference exceeds VKICK 100mV, the equalization is started once the difference exceeds VKICK 100mV, the balancer will discharge the higher voltage battery first, store that discharge energy in the inductor, and then charge that energy to the lower voltage battery. The balancer remains balanced until there is no difference in voltage between the two and/or two sets of batteries. Balancer technology allows balancing during the charge or discharge phase of the battery with minimal loss. When the voltages between the cells and/or the battery packs are in an equilibrium state, the balancer operates in a sleep mode with low supply current, which is an advantage in extending the life of the battery packs.
