IN-VEHICLE POWER SOURCE DISTRIBUTION DEVICE WITH BATTERY STATE DETECTING FUNCTION

摘要

PROBLEM TO BE SOLVED: To stabilize a balance of charge-discharge of a lead-acid battery by surely operating necessary minimum electric equipment in response to a state of the lead-acid battery.

SOLUTION: An electric current detecting part 51, a voltage detecting part 53 and a central control part 17 are arranged in this in-vehicle power source distribution device 10. Relays 11a and 11b are selectively controlled on ON/OFF in response to order of precedence prestored in a nonvolatile memory 13 so as to stabilize the balance of the charge-discharge of the lead-acid battery 5 on the basis of a detecting result by detecting a state of the lead-acid battery 5 on the basis of the detecting result in the electric current detecting part 51 and the voltage detecting part 53. The balance of the charge-discharge of the lead-acid battery 5 is stabilized by surely operating the necessary minimum electric equipment M1, M2, M3 and M4 in response to the state of the lead-acid battery 5.
