Title:
電池パックとその検査装置
Document Type and Number:
Japanese Patent JP4627588
Kind Code:
B2
Abstract:
A battery pack (2) having a reduced number of an inspection terminal (18) for inspecting operations of a battery protection circuit (11) for the battery pack (2), and an inspection device (1) for inspecting the operations of the battery protection circuit (11) for the battery pack (2) are provided. A voltage difference between an output voltage of a battery voltage memory circuit (41) for storing the voltage of a rechargeable battery (12), and an output voltage of a DC voltage power supply (42) is added to a voltage between a positive electrode input/output terminal (16) and a negative electrode input/output terminal (17), and the added voltage is provided for a control circuit (13) as an inspection voltage. Since the inspection terminal (18) serving as an input terminal for the inspection voltage and a wiring line are provided at one location, the size of a circuit board for constituting the battery protection circuit (11) is reduced, and the number of wiring lines is reduced for restraining an influence of electromagnetic radiation.
