What is the freezing point of the battery electrolyte?

  Normal battery sulfuric acid concentration is 35% -40%, according to the 'sulfuric-water mixture freezing point curve, we can know that the ice point of the electrolyte is between -60 ¡ã C to -50 degrees Celsius. From the data, as long as the battery fluid density is between 1.25-1.30, the possibility of icing is not large (unless you are using the car in the north of China).   However, as the concentration of sulfuric acid is lowered, the freezing point of the battery fluid increases, which makes the battery fluid a possibility of icing. For example, the lowest temperature in Beijing is generally less than ten degrees. When the battery fluid density is as low as 1.10, the battery has the possibility of icing. The most common cause of the above changes is that the battery is over-discharge.   Recommend: LiFePO4 Battery Manufacturer Energy storage battery Manufacturer Integrated machine energy storage battery series Manufacturer Lead lithium battery Manufacturer Outdoor Backup Battery Manufacturer Portable outdoor power supply Manufacturer Power battery Manufacturer Powerwall LiFePO4 Battery Manufacturer Battery rack Manufacturers Telecom LiFePO4 Battery Manufacturer Wall mounted battery storage Manufacturer China Lifepo4 Battery LiFePO4 Battery 48V 150AH LiFePO4 Battery 48V 100AH
