摘要

本实用新型提供一种汽车蓄电池启动电压测量电路，它能测量汽车发动机启动瞬间蓄电池的启动电压，并把测到的电压保存在保持电容内，使该电压变化率减小，从而提高了启动电压的测量精度。本电路还能在启动电压小于设定值时用LED灯报警，提示要对蓄电池进行维护。

3. Description: ABSTRACT OF THE DISCLOSURE: An electric storage battery for motor vehicles is composed of two subunits which are a main storage battery and an auxiliary storage battery. Both subunits are interconnected by a switch which, in one operational position, disconnects the auxiliary battery from the main battery and connects it directly to ignition terminals of the ignition system of a motor vehicle. Thus, the spark plugs of the engine receive the full voltage of the electric storage battery undiminished by voltage drops such as caused by operating the electric starting motor of the system. Thereby, the disadvantage of starting difliculties experienced with motor vehicles having normal electric storage batteries in cold weather is successfully avoided. The main unit has U-shaped plates, and these define a recess in which the auxiliary unit is received. [P] . 德国专利： DE2158206A1 . 1972-05-25
