Title: Battery charger
Inventor: NITTA TAKESHI
IPC: H02J7/14
Filed: 1990-03-06
Abstract: PURPOSE:To prevent a battery from being overcharged or overdischarged by correcting the characteristic variation of a current sensor by using the output value of the sensor when the generating voltage of a generator for charging becomes lower than the voltage of the battery at the time of measuring the output current of the generator by using the sensor. CONSTITUTION:A battery 4 connected with an electric load 5 is charged by using a generator 2, the output voltage of which can be changed. A generating voltage controller 1 incorporates a microcomputer 11 and stores the output of a current sensor 3 in a RAM 13 through a CPU 16 after AD conversion. The CPU 16 finds the relation between the output voltage and current value of the sensor 3 on the basis of a program stored in a ROM 12 and the data inputted to the RAM 13. Then the CPU 16 reduces the output current of the generator 2 to zero by lowering the generating voltage of the generator 2 below the voltage of the battery 4 through an output circuit 15 so as to correct the voltage and current characteristic of the current sensor 3.
