Abstract

The invention discloses a multi-battery disconnection detection circuit and a battery protection circuit board. The multi-battery disconnection detection circuit comprises a first disconnection detection circuit and N second disconnection detection circuits, the first disconnection detection circuit comprises a first detection comparison unit, a first detection resistor, a first capacitor and a current source; the first detection comparison unit is used for carrying out disconnection detection on the first battery according to the first negative end voltage; the ith second disconnection detection circuit comprises a second detection comparison unit, a second detection resistor and a second capacitor; and the second detection comparison units are used for detecting the disconnection of the (i + 1) th battery according to the voltage difference between the second negative terminal voltage and the second positive terminal voltage, wherein 1 < = i < = N. The multi-battery disconnection detection circuit can carry out disconnection detection according to the voltage difference between the two ends of each disconnection detection circuit, has detection real-time performance, and can carry out disconnection detection on all batteries.

Description

technical field [0001] The invention relates to the technical field of disconnection detection, in particular to a multi-cell battery disconnection detection circuit and a battery protection circuit board. Background technique [0002] At present, batteries have been widely used in electrical tools, electric vehicles or other electrical equipment. Existing storage batteries generally use a series-parallel design of multiple batteries to increase the voltage and capacity of the storage battery and provide power for high-power electrical equipment. In order to ensure the safe operation of multi-cell batteries, a battery protection board is required to detect abnormal conditions such as voltage, current, and disconnection of multiple batteries. Prevent overcharging or overcharging to cause damage to multiple batteries, and even cause safety accidents. [0003] The existing multi-cell battery disconnection detection circuit uses narrow pulse signals to detect battery disconnec...
