Abstract:
A current detection apparatus includes a current detection section that detects charging current and discharging current of the car driving battery, a level-shift circuit connected to the output-side of the current detection section that shifts the output of the current detection section, and an A/D converter connected to the output-side of the level-shift circuit. The level-shift circuit shifts the current detection section output signal to unbalance the maximum discharging current and maximum charging current that can be detected.
