Abstract

The invention provides a power-outputting battery pack. The power-outputting battery pack comprises a battery box, a power battery and a cooling device, wherein the power battery is located at the central part of the battery box; the cooling device comprises a water cooling system and an air cooling system; the air cooling system comprises the ventilation fan and a temperature controller, and theventilation fan is connected with a power source via the temperature controller; the water cooling system comprises a water pump and a water flow loop, the water pump communicates with one end of thewater flow loop, and the other end of the water flow loop passes through the bottom of the power battery in a zigzag way and then communicates with the water pump; the top of the power battery is evenly provided with a plurality of heat sinks; and the side walls and the bottom wall of the battery box are covered with heat-insulating noise-reducing protection layers. With such a design, the power-outputting battery pack of the invention not only has strong cooling effect, but also has high automation degree.

Description

technical field [0001] The invention relates to a power battery device, in particular to a power output battery pack, which is particularly suitable for enhancing the cooling effect to ensure the constant temperature of the surrounding environment of the power battery. Background technique [0002] With the rapid development of electric vehicles, the power battery system, as the core component that directly affects the working performance of electric vehicles, has higher and higher performance requirements. At present, the commonly used power battery system is lithium-ion battery, which has the advantages of high energy density, excellent power output characteristics and long life, but it has high requirements on the temperature of the surrounding environment, and it will be used if the temperature is too high or too low Reliability and security have a greater impact. In the prior art, there is a design for cooling the power battery, but the cooling effect is weak, and it i...
