AI Technical Summary

Benefits of technology

This patented technology provides an improved way for batteries that are protected from damage due to excessive charging/de-energizing currents during use. It includes two main components: one with a sensor switch unit attached to it while another control device controls its operation based on factors like temperature, voltage levels, etc., which helps prevent fires when there's only one component failing simultaneously. Overall this design ensures safe usage without adding extra parts such as wires or connectors.

Problems solved by technology

This technical problem addressed by this patented technology relates to improving the security of laminated Li- ion batteries during use without requiring external monitoring devices like current fuses or thermal sensors.

Abstract

The invention provides a battery protection circuit. The battery protection circuit is electrically connected between a cell unit and an external port to form a power supply loop, and the battery protection circuit comprises a first protection unit, a second protection unit and a sensing switch unit. The first protection unit is electrically connected between the battery cell unit and the second protection unit. The sensing switch unit is arranged at a preset position of the battery cell unit, and the sensing switch unit is electrically connected with the second protection unit. Under the condition that the sensing switch unit is triggered to be conducted and the first protection unit does not cut off the power supply loop, the second protection unit is controlled to protect the battery cell unit. The invention further provides a battery management system, a battery device and a control method thereof. The battery protection circuit provided by the invention has the advantages of highsafety, wide application range, relatively low cost and the like.
