PROBLEM TO BE SOLVED: To drive a vehicle immediately even if a fitted battery dries up during driving, by fitting a controller which control charging starting or stopping for a main cell by a secondary cell whose rated voltage is high, and a switching device interlocked with a limit switch. SOLUTION: A secondary cell 1 is set in its rated voltage, preferably, to 110 % to 140% of a main cell 3 which is an object of charging. A controller 4 for controlling timing of charging for a secondary cell 1 and a main cell 3, a switching device for interlocking with a limit switch 6, and a main switch 8 are all connected in a loop. When the main switch 8 is turned on if a motor vehicle is in a remarkably bad condition, the main cell 3 it charged by the secondary cell 1 whose voltage is higher than the main cell 3, and the surface part of its electrode can be activated. It is possible to take out large current necessary at the time of driving start, thus permitting the motor vehicle to be driven. |
