Electric vehicles can use car heaters. Car heaters are also called external heaters. They can be roughly divided into two types. One is an electric heater heated by a resistance, with a power of about 120W. larger power, about 500W. However, it should be noted that when using the heater, pay attention to the usage time to avoid excessive use of battery power. Heaters of different wattages can be used at different times.
For example, the capacity of a car battery is 45 to 60 Ah, which can store 540 to 720 Wh of electricity. Assuming that a heater with a power of 120 W is used, in theory it can be used for 4 people. hours, but due to battery life considerations, the problem is that the actual usage time should be reduced by halfie. If used for an hour after turning off the engine, it is best to start the vehicle and let it idle for a few minutes to charge. the battery.
According to the capacity of the car battery, it is not suitable for 500W heater. Therefore, when choosing a car heater, you should mainly choose it according to the capacity of the vehicle battery. You can't choose. using one with too high a rating will increase the load on the generator.
In addition to the car heaters mentioned above, you can also choose to modify the built-in heater, that is, diesel heater, which uses diesel as a heat source and obtains heat by burning diesel to achieve the purpose of heating.
