具体实施方式Detailed ways

图1～图2为本发明的一种具体实施方式。包括：压敏电阻2、充电电阻3、充电继电器4、补偿继电器5、暂态储能模块6，其中，暂态储能模块6又由若干超级电容模块串联构成，每个超级电容模块由超级电容7、静态均压电阻8和动态均压稳压二极管9并联构成。1 to 2 are a specific embodiment of the present invention. Including: varistor 2, charging resistor 3, charging relay 4, compensation relay 5, transient energy storage module 6, wherein the transient energy storage module 6 is composed of several supercapacitor modules connected in series, and each supercapacitor module consists of a supercapacitor The capacitor 7, the static voltage equalizing resistor 8 and the dynamic voltage equalizing and stabilizing diode 9 are connected in parallel.

本发明的汽车电瓶暂态功率补偿器有两个输出端子，如图1所示的P，N，端子P接到汽车电瓶的正极，端子N接到负极。汽车发动机起动前，充电继电器4和补偿继电器5处于断开状态。发动机起动后，充电继电器4闭合，补偿继电器5仍然处于断开状态。电源通过充电电阻3、充电继电器4向暂态储能模块6充电。当暂态储能模块6的端电压上升到12伏时，补偿继电器5闭合。汽车电瓶暂态功率补偿器1进入补偿工作状态，补偿汽车电源系统的冲击负荷功率，抑制电压的脉动和纹波，从而改善汽车动力、油耗、积碳、尾气等性能。由于大幅度减少了电瓶的充放电次数，可以显著延长电瓶的工作寿命。The vehicle battery transient power compensator of the present invention has two output terminals, P and N as shown in Figure 1, the terminal P is connected to the positive pole of the vehicle battery, and the terminal N is connected to the negative pole. Before the automobile engine is started, the charging relay 4 and the compensation relay 5 are in disconnected state. After the engine is started, the charging relay 4 is closed, and the compensation relay 5 is still in an open state. The power supply charges the transient energy storage module 6 through the charging resistor 3 and the charging relay 4 . When the terminal voltage of the transient energy storage module 6 rises to 12 volts, the compensation relay 5 is closed. The vehicle battery transient power compensator 1 enters the compensation working state, compensates the impact load power of the vehicle power system, and suppresses the voltage pulsation and ripple, thereby improving the performance of the vehicle such as power, fuel consumption, carbon deposits, and exhaust. Since the charging and discharging times of the battery are greatly reduced, the working life of the battery can be significantly extended.

当汽车发动机关闭，充电继电器4和补偿继电器5在电瓶端电压下降到12伏时，同时断开，避免电瓶在发动机关闭后仍长时间对补偿器的暂态储能模块充电。When the automobile engine is turned off, the charging relay 4 and the compensation relay 5 are disconnected at the same time when the battery terminal voltage drops to 12 volts, so as to prevent the battery from charging the transient energy storage module of the compensator for a long time after the engine is turned off.
