Can a Car Air Conditioner Be Powered by a Battery?
1 Answers
Car air conditioners can be powered by a battery, but a high-power battery is required. The voltage of air conditioners is typically AC 220V, so a 220V battery is needed. A 1P air conditioner requires at least a 1KW or higher battery to operate. Additional information: Voltage required for air conditioner operation: 1. Air conditioners generally undergo low-voltage and high-voltage tests before leaving the factory, meaning they are required to operate at the minimum voltage. For standard air conditioners with a rated voltage of 220V, the minimum operating voltage is 220 * 90% = 198V. 2. Unless it is an air conditioner with special functions, such as wide voltage operation, the minimum voltage can reach 187V or even lower. However, according to the formula P = UI, when the power is constant, the lower the voltage, the higher the current. Therefore, air conditioners cannot operate at too low a voltage for this reason. If the voltage is too low and the current is too high, it will exceed the compressor's protection current value, causing the compressor to shut down for protection.
