Patent Searching and Data


Title:
A charge-and-discharge control circuit and a battery device
Document Type and Number:
Japanese Patent JP6066840
Kind Code:
B2
Abstract:
The present invention provides a charge and discharge control circuit and a battery device capable of detecting an intermediate terminal disconnection without causing the balance between battery voltages to collapse and shortening the service life of the battery device. A charge and discharge control circuit which controls charging/discharging of a plurality of secondary batteries connected in series is equipped with intermediate terminal disconnection detecting circuits each of which is provided between a positive electrode terminal and a negative electrode terminal of each secondary battery and detects an intermediate terminal disconnection of each intermediate terminal by intermittently equal detection currents.
