Title
(EN) Circuit board in battery, battery cell assembly and battery
(ZH) 电池中的电路板、电芯组件及电池
Abstract
(EN)
The utility model provides a circuit board in a battery, a battery cell assembly and the battery, the circuit board comprises a substrate, at least one patch part is arranged on the substrate, and thepatch part is used for setting a through-flow guide sheet for conducting current; at least part of the patch part of the substrate is of a hollowed-out structure penetrating through the substrate, and the through-flow guide piece is connected with at least part of the patch part. According to the technical scheme, the hollow structure is arranged in the substrate, so that the weight of the circuit board can be effectively reduced when the same number of battery cells are connected, the weight of the whole battery pack with the circuit board is reduced, and the endurance time of the battery isprolonged.
