摘要： PROBLEM TO BE SOLVED: To provide a battery pack, along with an overcurrent detection method of the battery pack, capable of detecting a current which is smaller than a current essentially detectable in a non-power saving state, in a short time with no increase in power loss accompanied in a power saving state.SOLUTION: A voltage across both ends of a curent detection resistor 2 of 2.5 mΩ that is inserted in a charging/discharging path of a battery 1 is detected with a comparator 81 while a control part 5 is in a power saving state. If the detected voltage exceeds a voltage (2.4 mV) that is lower than a voltage (50 mV) at the time an overcurrent 1 of 20 A is detected in a non-power saving state, such information is stored in a register 82. If a CTRL signal indicating that a load device 20 is in the power saving state is inputted into an I/O port 55 while the information is stored in the register 82, a CPU 51 detects an overcurrent 2 of about 1 A to shield a breaker 7, and a communication part 9 transmits alert information to a control/power supply part 21.
