AI Technical Summary
Technical Problem
Existing battery modules require external voltmeters to be connected to the positive and negative terminals on both sides of the battery when collecting voltage, which results in high wiring costs and space requirements.
Method used
Design a cell cover plate including a current-carrying terminal and a sampling terminal. Voltage measurement is achieved through a same-side conductive tab. Stability and insulation are improved by combining an insulating component and a snap-fit groove structure.
Benefits of technology
It reduces the wiring cost and routing space requirements of battery components, improves structural stability and safety, and supports high-rate charging and discharging.

Abstract
The application relates to a battery cell cover plate, a battery assembly, a battery pack and a vehicle. The battery cell cover plate is used in connection with a pole core. The battery cell cover plate comprises a body part, a flow-through pole and a collection pole. The body part comprises a flow-through opening and a collection opening distributed along a length direction. The flow-through opening and the collection opening both penetrate the body part along a thickness direction. The flow-through pole is arranged at the flow-through opening and is insulatedly connected with the body part. The flow-through pole is used to conduct with a first tab of the pole core. The collection pole is arranged at the collection opening and is insulatedly connected with the body part. The collection pole is used to conduct with a second tab of the pole core. The first tab and the second tab are opposite in polarity. Wherein, the length direction is different from the thickness direction.
