When the automobile power system booster is used in parallel for a long time in the automobile lead acid start battery The capacitor in the capacitor energy storage module adopts series discharge and series charging. Due to the difference in internal resistance during the manufacturing process of the capacitor, the voltage across each capacitor in the series charging circuit is not uniform. The main function of the module management circuit 3 is to limit the voltage shunt to protect each capacitor from overvoltage charging. When the vehicle electric system booster is used for vehicle rescue by external power supply, the capacitor energy storage module The management circuit 3 automatically switches the mode of use of the capacitor to the form of series discharge and parallel charge, which ensures that the charging voltage of each capacitor is consistent, and effectively protects the use of the capacitor energy storage module.
图 3示出了电容储能模块管理电路的上限压分流模块电原理， 其中： Figure 3 shows the electrical principle of the upper limit voltage shunt module of the capacitor energy storage module management circuit, wherein:
VT1为检测电路， 当电容两端电压超过设定电压时输出端高电平， 驱动开
关管工作； VT1 is the detection circuit. When the voltage across the capacitor exceeds the set voltage, the output terminal is high, and the drive is turned on. Guan Guan work;
V1〜V2开关管， 当其控制电压达到导通电压时管子导通； V1~V2 switch tube, when the control voltage reaches the conduction voltage, the tube is turned on;
R1电阻为 VT1的上拉电阻； The R1 resistor is a pull-up resistor of VT1;
R2〜R3为 V1〜V2的匹配电阻， 以减少各开关管导通电压不一致所带来的 相互影响； R2 to R3 are matching resistors of V1 to V2 to reduce the mutual influence caused by the inconsistent on-voltage of each switch;
R4〜R7为限流电阻， 当 V1〜V2导通时限制其流过的电流； R4~R7 are current limiting resistors, and limit the current flowing when V1~V2 are turned on;
上述电阻均采用大功率电阻。 The above resistors all use high power resistors.
其工作原理是： 超级电容器充电时电容器正负两极间的电压在不断上升， 在电容两端的电压未达到 VT 1的阈值电压时 VT1的输出端输出低电平， V1〜V2 均不导通呈高阻状态电容器的电压继续升高。 当电容器两端的电压达到 VT 1的 阈值电压后 VT 1 的输出端有低电平变为高电平， 此时 V1〜V2均导通工作等效 于在电容器正负电极两端并联上了分流电阻， 使对与之并联的电容器的充电电 流进行分流， 故电容器上的电压就会降低上升的速率， 如果充电电流等于平衡 电路的旁路电流电容器的电压就不会上升。 由于 VT 1具有施密特特性当电容两 端电压下降到 VT1的关断电压时 VT1的输出端又会变为低电平 V1〜V2均关断 停止对电容器的充电电流的分流， 这个工作过程是反复进行的这样就可使电容 器两端的电压最高不会超过 VT 1的阈值电压， 选择合适的阈值电压值， 可以有 效的保护超级电容器在串联充电工作状态下的安全。 The working principle is as follows: When the supercapacitor is charged, the voltage between the positive and negative poles of the capacitor is continuously rising. When the voltage across the capacitor does not reach the threshold voltage of VT1, the output of the VT1 outputs a low level, and V1~V2 are not turned on. The voltage of the high resistance state capacitor continues to rise. When the voltage across the capacitor reaches the threshold voltage of VT 1, the output of VT 1 has a low level and becomes a high level. At this time, the conduction of V1 to V2 is equivalent to the shunting of the positive and negative electrodes of the capacitor in parallel. The resistor shunts the charging current of the capacitor connected in parallel, so that the voltage across the capacitor decreases the rate of rise, and the charging current does not rise if it is equal to the voltage of the bypass current capacitor of the balancing circuit. Since VT 1 has a Schmitt characteristic, when the voltage across the capacitor drops to the turn-off voltage of VT1, the output of VT1 becomes low again. V1~V2 are both turned off to stop the shunting of the charging current of the capacitor. This is repeated so that the voltage across the capacitor does not exceed the threshold voltage of VT 1, and the appropriate threshold voltage value can be selected to effectively protect the supercapacitor in the series charging state.
众所周知铅酸启动电池为化学电源， 依靠氧化还原反应实现电能贮存和释 放， 其电能的贮存和释放速度即瞬间功率， 受温度影响明显， 其电池寿命与电 池内参与电化学反应的活性物质的电化学活性相关， 为克服上述矛盾， 本实用 新型汽车电系统倍力器采用物理储能方式， 将电荷以物理形式直接存储在电容 储能模块内， 电容储能模块内的化学物质在电能的贮存和释放过程中不发生电 化学反映， 因此汽车电系统倍力器具备了瞬间大电流充电和瞬间大电流放电及 优良的低温特性， 在与汽车铅酸启动电池并联使用中， 在汽车启动瞬间由汽车 电系统倍力器提供绝大部分启动电能， 汽车铅酸启动电池只输出较少电能甚至 不用输出电能， 在该方案中汽车铅酸启动电池寿命被成倍延长， 低温特性得到 大幅改善。
It is well known that lead-acid start-up batteries are chemical power sources, relying on redox reactions to achieve electrical energy storage and release. The storage and release rate of electrical energy is instantaneous power, which is obviously affected by temperature. The battery life is related to the electrical activity of the active substances participating in the electrochemical reaction in the battery. Chemical activity related, in order to overcome the above contradiction, the utility model of the utility model uses a physical energy storage method to store the electric charge in a physical form directly in the capacitor energy storage module, and the chemical substance in the capacitor energy storage module is stored in the electric energy. And the electrochemical reaction does not occur during the release process. Therefore, the automotive electric system booster has instantaneous high-current charging and instantaneous high-current discharge and excellent low-temperature characteristics. In parallel with the automobile lead-acid starter battery, at the moment of starting the car The automotive power system booster provides most of the starting energy. The car lead-acid starter battery only outputs less power or even no output power. In this scheme, the battery life of the automobile lead acid is doubled and the low temperature characteristics are greatly improved.
