Heat dissipation is very important for new energy vehicles, because their heating power is particularly large, which requires the use of high-quality high-power radiators, while traditional air-cooled radiators generally cannot meet their heat dissipation requirements, especially for new energy vehicles. The heat dissipation of the battery pack has the characteristics of airtightness. The design index requires that the electric vehicle can run efficiently and stably under various weather conditions throughout the year, and the vehicle battery pack directly affects the acceleration and endurance of the vehicle, so it is stable Performance is one of the key technologies of the vehicle, and the key technology to ensure the stable performance of the battery pack lies in its heat dissipation. The battery heat dissipation of power vehicles generally uses a water-cooled heat dissipation system to dissipate heat. The excellent water-cooled plate radiator and related pipeline connection technology ensure that it runs at a suitable temperature.

Battery pack

An excellent temperature management system for power battery packs needs to ensure that the temperature of each single battery is constant throughout the year. Even if a large number of batteries are used in extremely hot weather, it can ensure timely heat dissipation and prevent battery life from weakening or swelling. It explodes and uses a large number of batteries in extreme cold weather to ensure that the inside of the battery is warm enough without affecting performance and life. The heat dissipation of the battery is to use liquid coolant to flow through the water cooling plate at the bottom of the battery pack, and then the cooling plate with excellent thermal conductivity directly contacts the single battery, so that the battery is quickly cooled.

Water cooling plate radiator

According to the technicians of major water-cooling plate manufacturers, the heating and keeping warm of the power battery of the new energy vehicle is completed by the heater. The power of the heater comes from the battery itself, which will shorten the battery life of the electric vehicle in cold weather. , The heat dissipation system and the heating system constitute the overall thermal management system of the electric vehicle.

Charging in extreme environments is a technical difficulty in the development of new energy vehicles, because new energy vehicles are turned off when charging, but the temperature management system needs to be automatically activated when the charging is learned, and the heating system is activated for heating to maintain The internal temperature of the battery pack, in other words, when the entire car is asleep, the battery pack is still awake and on standby at any time. The technical staff of the water-cooling board manufacturer pointed out that in the initial stage of charging, whether the heating system can automatically start heating to ensure the temperature of the battery is very important. This requires a high degree of sealing of the power battery pack shell, and good sealing performance ensures temperature storage. .
