Problems solved by technology

[0003] For the air-cooled thermal management system, due to the need to add fans, air ducts and other equipment, the design difficulty also increases, so it is not conducive to lightweight and compact, and the operation of the fan needs to consume the power of the power battery pack, affecting the battery life of the whole vehicle
[0004] For the liquid-cooled thermal management system, since the cooling liquid circulates in the thermal management system, once the cooling liquid leaks, it will harm the battery inside the battery pack, thereby affecting the performance of the battery, and due to the need to increase components such as liquid cooling pipes, It not only increases the difficulty of the process, but also is not conducive to lightweight and compactness. At the same time, the liquid-cooled thermal management system itself has a certain amount of energy consumption, which further increases the burden on the power battery and affects the battery life of the whole vehicle.

Abstract

The application discloses a power battery pack and a vehicle. The power battery pack comprises a tray and an upper cover, wherein the upper cover is connected to the tray to define a battery individual receiving cavity; a plurality of battery individuals installed in the battery individual receiving cavity. A heat-conducting insulating layer is disposed between the battery individuals and the upper cover and the upper cover includes a heat-conducting plate. The power battery package of the application has a simple structure, low assembly cost, high energy density, and a good heat dissipation capability, and does not consume the cooling capacity of the whole vehicle during heat dissipation.

Description

Technical field [0001] This application belongs to the technical field of power battery manufacturing, and specifically relates to a power battery pack and a vehicle having the power battery pack. Background technique [0002] The temperature distribution of the power battery pack has a great influence on its life and endurance. In related technologies, the thermal management system of the power battery pack usually includes air-cooled and liquid-cooled. [0003] For the air-cooled thermal management system, due to the need to add fans, air ducts and other equipment, the design difficulty is also increased, which is not conducive to lightweight and compactness, and the operation of the fan consumes the power of the power battery pack, which affects the vehicle life. [0004] For liquid-cooled thermal management systems, due to the coolant circulating in the thermal management system, once the coolant leaks, it will harm the battery inside the battery pack, thereby affecting the perfo...
