End plate of battery module and battery module
View Patent ↗The present application relates to the field of battery production techniques and, particularly relates to an end plate for battery module and a battery module. The end plate includes a panel, an elastic member and a buffer plate, the panel and the buffer plate are stacked, a supporting hole is defined in the buffer plate, the supporting hole is a through hole along a thickness direction of the buffer plate, the elastic member is filled in the supporting hole, and an end of the elastic member abuts against the panel tinder such structure, the end plate can be avoided from directly squeezing the cell in the battery module, so as to protect the cell and guarantee safety of the battery module.
1. An end plate of a battery module, comprising a panel, an elastic member and a buffer plate, wherein the panel and the buffer plate are stacked, a supporting hole is defined in the buffer plate, the supporting hole is a through hole along a thickness direction of the buffer plate, the elastic member is filled in the supporting hole, and an end of the elastic member abuts against the panel.
2. The end plate of a battery module according to claim 1 , further comprising a temperature control member; wherein a temperature control hole is defined in the buffer plate, the temperature control member is filled in the temperature control hole, and an end of the temperature control member is attached to the panel.
3. The end plate of a battery module according to claim 1 , wherein the elastic member and the panel are integrated as a whole.
4. The end plate of a battery module according to claim 2 , further comprising an adhesive located between the panel and the buffer plate.
5. The end plate of a battery module according to claim 4 , wherein the panel is made of a resin, a slot is defined at each of two sides of the buffer plate, and the slot is filled with the adhesive and/or the resin.
6. The end plate of a battery module according to claim 5 , wherein the slot comprises a plurality of transverse slots and a plurality of longitudinal slots, the plurality of transverse slots and the plurality of longitudinal slots intersect with each other, and the supporting hole is defined at an intersection of one of the plurality of transverse slots and one of the plurality of longitudinal slots.
7. The end plate of a battery module according to claim 6 , wherein one of the temperature control hole is defined in each area defined by every two adjacent transverse slots and every two adjacent longitudinal slots.
8. The end plate of a battery module according to claim 1 , comprising two panels, wherein the buffer plate is located between the two panels, and two ends of the elastic member abut against the two panels, respectively.
9. A battery module, comprising a cell, a side plate and the end plate according to claim 1 , wherein the side plate is connected with the end plate, and the buffer plate is closer to the cell than the panel when the end plate comprises only one panel.
10. The battery module according to claim 9 , wherein the side plate comprises a bending edge, the bending edge bends toward an interior of the battery module, and the end plate is connected with the bending edge of the side plate.
