Title:
OVERCURRENT DETECTOR, CHARGE AND DISCHARGE SYSTEM USING THE OVERCURRENT DETECTOR, DISTRIBUTION PANEL, CHARGE CONTROLLER, VEHICLE CHARGING/DISCHARGING DEVICE, ON-VEHICLE ELECTRONIC APPARATUS
Document Type and Number:
Japanese Patent JP2014207766
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To properly detect overcurrent both in charging and discharging.SOLUTION: A determination section 12 sets each of a first threshold value Vf1 to be compared with a measured value of a charging current and a second threshold value Vf2 to be compared with a measured value of a discharge current to a value different from each other. With this, overcurrent can be detected properly in both of charging and discharging. Also, since the first threshold value Vf1 for the charging current is set to a higher (larger) value than the second threshold value VF2 for the discharge current, the charge time can be reduced, the discharge time can be elongated, and an on-vehicle battery 40 can be prevented from degrading during discharging.
