Problems solved by technology
However, this solution relies on BMS hardware for detection and control. If the detection hardware or control hardware fails, it will directly lead to the failure of the anti-overcharge function.
Especially when the user uses a non-standard charger, it is easy to cause the control hardware to be broken down, resulting in the failure of the charging circuit to be disconnected, thus causing a safety accident

The invention relates to the technical field of battery protection, in particular to a circuit connecting device, a battery module and electric equipment. The circuit connecting device comprises a first component and a second component which are sequentially arranged in a stacked mode in the first direction, the first component is conductive and comprises a first section, a second section and a third section, the first section and the second section are arranged on the first component in a spaced mode, and the third section is connected with the first section and the second section. The second component extends towards the first component and is provided with a boss, and the boss and the third section are at least partially overlapped when observed in the first direction. A gap is formed between the boss and the third section in the first direction, the first component and the second component can be close to each other, and the boss is configured to be capable of extruding the third section to enable the third section to be broken, so that electric connection between the first section and the second section is disconnected, and disconnection of the charging loop is achieved.
Description
technical field [0001] The present application relates to the technical field of battery protection, in particular to a circuit connection device, a battery module and electrical equipment. Background technique [0002] The soft-pack power battery is prone to thermal runaway after overcharging, which brings potential safety hazards. The existing technology mainly uses BMS to detect voltage, temperature, gas, etc. After abnormality is detected, BMS controls the charging circuit to disconnect, so as to prevent overcharging. However, this solution relies on BMS hardware for detection and control. If the detection hardware or control hardware fails, it will directly lead to the failure of the anti-overcharge function. Especially when the user uses a non-standard charger, it is easy to cause the control hardware to be broken down, resulting in the inability to disconnect the charging circuit, thus causing a safety accident. Contents of the invention [0003] The main technica...
