What is the source of power for additional electrical appliances when driving? Can I use a rice cooker if my car is equipped with an auxiliary battery?

Many riders, especially those who travel long distances, use car rice cookers in order to have convenient meals in the car. Generally, there is no problem with car rice cookers, but some riders have installed auxiliary batteries and isolators in the car. Can the car electrical appliances still be used in this case? Let’s read the following content to find out!

What is the source of electricity for additional electrical appliances while driving?

When using additional electrical appliances while driving, the main source of power is the car generator. When the generator is insufficient and the power of the electrical appliances exceeds the generator power, the battery will provide the shortfall. The generator and the battery are connected in parallel, and in theory they both supply power to the load. However, the generator output voltage is relatively high, at least 1.5-2V higher than the battery voltage. This creates a voltage difference. When the generator and the battery are connected in parallel, the generator will charge the battery. When using additional electrical appliances, the generator has a higher voltage than the battery, so the generator will give priority to supplying power to the load.

Can I use a rice cooker if my car is equipped with a secondary battery?

No problem at all, you can cook and boil water while driving. Even if you don't install a secondary battery, you can use a rice cooker while driving, as long as the power is not too high. Also pay attention to whether your plug is a high-power plug, otherwise it is easy to burn your plug.

The vehicle is charging the battery at any time while driving, so the battery you use is basically powered by the generator, which will charge the battery at any time and will not cause any damage to the battery.

What should you pay attention to when using an electric cooker after installing a secondary battery in your car?

That is, the auxiliary battery is fully charged, or the auxiliary battery is disconnected when cooking. If you use a rice cooker below 500w, you don’t need to wait for the auxiliary battery to be fully charged, nor do you need to disconnect the auxiliary battery. However, when using a rice cooker of 800w or higher power, it is necessary to disconnect the auxiliary battery or wait for the auxiliary battery to be fully charged before use.
