Abstract

The present application relates to the field of lithium battery technology, and particularly to a battery pack. The battery pack includes a cell module, at least one thermal protection component, a plurality of support bars, a bottom plate, a housing, and a gas passage crossbeam. The bottom plate is connected to the housing such that the bottom plate and the housing together enclose an accommodation space. The bottom of the cell module is provided with at least one row of explosion-proof valves. The cell module is disposed on the thermal protection component, and each thermal protection component is disposed corresponding to one row of explosion-proof valves. The thermal protection component is disposed on the bottom plate with the support bars disposed on both sides of each thermal protection component. The cell module is disposed on the bottom plate via the support bars, such that two support bars disposed on both sides of the thermal protection component, the thermal protection component, and the bottom of the cell module together enclose an exhaust passage. The gas passage crossbeam is disposed on the bottom plate, and the exhaust passage is in communication with the gas passage crossbeam. The housing includes an exhaust portion, and the exhaust passage is in communication with the exhaust portion via the gas passage crossbeam. The battery pack of the present application improves the discharge speed of vent gas and achieves electrical and thermal separation within the battery pack.
