CHARGING SYSTEM OF ELECTRIC POWER-DRIVEN TOOL, BATTERY POWER SOURCE OF ELECTRIC POWER-DRIVEN TOOL, AND CHARGING DEVICE FOR BATTERIES OF ELECTRIC POWER-DRIVEN TOOL Russian patent published in 2014 - IPC H02J7/00

Abstract RU 2508592 C2

FIELD: electricity.

SUBSTANCE: each of the charging device for batteries and the battery power source has a microcomputer. Corresponding microcomputers jointly perform data exchange while the battery power source is charged by means of the charging device for batteries and confirm the working state of the microcomputer of the other side of data exchange (confirmation of interaction) based on the data exchange result. When malfunction of one of the microcomputers is detected, the other microcomputer performs a pre-defined process to stop the charging operation.

EFFECT: improving battery charging efficiency.
