Abstract

The invention provides a serioparallel battery pack which comprises a base shell, an upper cover assembly and at least one parallel battery cell, wherein the batteries of the parallel battery cells are connected in series; a wind inlet is arranged on the base shell; a wind outlet is arranged on the upper cover assembly; one side of the wind outlet is provided with a radiating fan. The battery pack is simple and compact in structure, wide in application scope and long in service life. With the adoption of the battery pack, the temperature balance is enhanced observably, the balanced heat radiating performance is good, and the security is high.

Description

technical field [0001] The invention relates to a hybrid battery pack. Background technique [0002] The battery is the core component of the battery pack, and the consistency of the battery is the key point to ensure the overall performance of the battery. Usually, under the premise of quality control, it is often necessary to choose a reasonable power distribution group scheme. However, no matter how hard we try at this stage, we cannot 100% guarantee the consistency of the batteries. In actual use, due to the local imbalance of the environment and working conditions, the consistency will become worse and worse. [0003] The heat dissipation performance of the battery module is an important factor affecting the working performance, working efficiency, service life and safety of the battery. Existing battery modules usually adopt an integral exhaust and heat dissipation structure, which has low heat dissipation efficiency, uneven temperature among battery packs, short ba...
