| 摘要 |
The current detection apparatus is provided with a current detection section (20; 30) that detects charging current and discharging current of the car driving battery (10), a level-shift circuit (40; 50) connected to the output-side of the current detection section (20; 30) that shifts the output of the current detection section (20; 30), and an A/D converter (60) connected to the output-side of the level-shift circuit (40; 50). The level-shift circuit (40; 50) shifts the current detection section (20; 30) output signal to unbalance the maximum discharging current and maximum charging current that can be detected.
