Title:
BATTERY CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/116905
Kind Code:
A1
Abstract:
A battery control device comprises: an MCU which includes a first control terminal, a first sensing terminal connected to a first node, a second control terminal, a third control terminal, a second sensing terminal connected to a second node, and a fourth control terminal, and which senses voltage changes in the first node and the second node; a relay including a coil and a switch which are connected between the first node and the second node; and a first reduction circuit composed of a first transistor which includes a first gate connected to the first control terminal and a first end connected to the first node, and a second transistor which includes a second gate connected to the second control terminal, the first end connected to the first node, and a second end connected to the second node, wherein the MCU is configured to control each of the first gate and the second gate such that the first transistor is turned on and the second transistor is turned off when there is no voltage change in the first node.
