Abstract

The embodiment of the invention provides a battery protection circuit. A first switch unit is electrically connected between a battery cell unit and external equipment. A sensing switch unit is electrically connected with the first switch unit, and the first switch unit is used for connecting or disconnecting the electric connection between the battery cell unit and the external equipment throughthe connection or disconnection of the sensing switch unit. The embodiment of the invention further provides a battery. Thus, the battery protection circuit and the battery provided by the embodimentof the invention have the advantages of high response speed, high controllability and low cost. The temperature of the battery can be monitored in real time, and charging and discharging of the battery can be controlled according to the temperature of the battery. The safety and stability of the battery can be remarkably improved.

Description

technical field [0001] The present application relates to the field of battery technology, in particular to a battery protection circuit and a battery. Background technique [0002] With the rapid development of consumer electronics, the application of lithium-ion batteries is also increasing. At present, lithium-ion batteries have been widely used in electric equipment such as mobile phones, digital cameras, electric vehicles, vacuum cleaners, sweeping robots, and drones. [0003] However, when charging the battery, if the charging voltage is unstable or the charger is damaged, resulting in excessive charging current or charging voltage, or when the battery is continuously discharged with a large current, the above situations will cause Serious heating of the battery may even cause the battery to burn. Contents of the invention [0004] In view of this, it is necessary to provide a battery protection circuit and battery, which have the advantages of fast response, stron...
