電池液冷系統是非常重要的一項. It is a core component of high-voltage power equipment and is used to ensure battery performance and avoid battery thermal runaway. The battery liquid cooling system drives coolant through the system via a water pump, 然後使用熱交換單元吸收電池的熱量, 最後透過散熱器將熱量排放到大氣中, 從而冷卻動力電池. 我將在下面詳細描述它是如何工作的.
電池液冷卻系統
我擔心有些人還不明白這一點, so I'll explain it briefly. 首先是電池, 無論是充電還是放電, 伴隨著電子運動, 產生熱量. This is an unavoidable phenomenon. Engineers designed the battery cooling system to remove this heat. It regulates the battery pack’s temperature to ensure it stays within the proper range. 否則, it will not only affect the performance and lifespan of the power battery pack but also trigger thermal runaway, 導致用電設備損壞, 爆炸和其他安全問題.
電動客車電池冷卻系統, 電動卡車, 電子重型設備, 電動船, ETC.
如今, there are three main types of common battery cooling systems, 空氣電池冷卻, 液態電池冷卻, 和直接冷媒冷卻. 除了這些, 還有浸入式電池冷卻等. 其他這些還沒有商業化, 所以它們不在討論範圍之內.
Different cooling methods work differently. Battery liquid cooling systems are the focus of this discussion. 我將詳細介紹此電動汽車電池冷卻解決方案.
電子水泵: 它負責驅動系統內的冷卻劑在管道中循環並不斷冷卻.
液體管道: It is responsible for providing a flow path for the coolant to contact and cool the power battery module.
冷凝器: It is responsible for radiating the heat absorbed by the coolant to the atmosphere.
熱交換器: 負責將電池產生的熱量傳遞給冷卻劑.

當動力電池升溫需要冷卻時, the power battery will exchange heat with the coolant through the cooling plate.
The coolant receiving heat is sent into the heat exchanger by the electronic water pump. 熱交換器內部, 一側流入冷媒, 另一側流入熱冷卻液, 兩者在熱交換器中進行熱交換.
The heat is carried away by the refrigerant and the cooler coolant flows out and back to the battery, 創建一個循環;
The hotter refrigerant then dissipates the heat through a customized compressor and condenser, 創建一個循環.
Battery cooling for large electric devices is easy with the dual cycle system.
對於一些寒冷的國家, 動力電池需要加熱. 我們加入一個配件 - 一個 PTC液體加熱器. It works by first closing the cooling circuit and turning on the PTC liquid heater. The coolant is heated by the PTC and flows to the battery, 由冷卻板加熱的地方.
散熱效果好: 與風冷相比, 液冷效果更好更穩定. 徹底解決動力電池過熱問題.
適用性強: 與冷媒直冷、浸沒式冷卻相比, 它更適用. 對環境的要求沒那麼苛刻.
可控性強、精準度高: the system collects temperature data in real-time and intelligently adjusts parameters such as coolant flow and condensing fan speed. This can achieve a balance between precise control of power battery temperature and energy saving.
Utilizing the temperature difference between the battery system's own temperature and the surrounding environment temperature, 透過空氣對流熱交換降低電池溫度. Manufacturers typically equip it with multiple fans to accelerate heat transfer.
The advantage of this kind of cooling is its simple structure and lower cost. 缺點是散熱效果不夠理想.
使用冷媒作為熱交換介質, the use of refrigerant in the gas-liquid phase change process absorbs a large amount of heat characteristics, 以達到快速冷卻的目的.
這種散熱方式的優點就是散熱效果好. 缺點是技術複雜, 成本高, 並且不能加熱.
After understanding the various cooling methods above, you will find that the battery liquid cooling system is currently the most mature solution for electric vehicle battery cooling systems. This is especially true in scenarios that require high power output and long hours of operation, 例如 電動客車電池冷卻系統, 電動卡車電池冷卻系統, 和 電動重型設備電池冷卻系統.

問: 電池冷卻使用什麼冷卻液?
一個: The common coolants used for battery cooling are water or glycol.
問: 電動車電池有冷卻系統嗎?
一個: 當然有, 因為電動車有高能量電池. 為了更高的功率, the instantaneous energy required is huge and therefore the heat generated will be huge.
問: 為什麼電池冷卻很重要?
一個: 我以手機電池為例，以便於理解. 夏天使用手機時電池溫度升高, the phone will alarm and reduce performance to avoid the battery continuing to heat up. 如果繼續升溫, 它會導致手機自動關機. 這用於保護手機免受損壞和爆炸.
當你在冬天使用手機時, 您會注意到電池的持續時間較短. 這是因為電池活性下降.
