Electricity principle of RV, usage method of RV lithium battery. RV is a model that has sold very well in my country in recent years. The appearance of RV has been favored and liked by many enthusiasts. At present, many car owners will take their families to travel all over the country after purchasing an RV to experience a different RV life. But after playing the RV for so long, do you really understand the electricity consumption of the RV?
Principles of RV Electricity
When the RV is driving, the generator will generate electricity to directly charge the battery of the RV. The batteries of the car and the house of the RV are independent of each other, and there will be no mutual loss during use. In addition, it can also provide electricity to the RV through the campsite’s external power supply and solar energy. Three kinds of power supply methods plus life battery electric shock, comprehensive comparison, solar + mains is the best configuration choice for ordinary RV camping life. Fuel generators can be added to those with large electricity consumption to achieve the simultaneous use of three power supply modes.
The battery on the RV is divided into the main car battery and the life battery. The main car battery is to ensure the use of the main car’s electricity system, and the life battery is to ensure the life electricity in the RV. Under normal circumstances, the electricity on the RV is divided into 12V (a few still have 24V, 48V), 220V (some imported vehicles are 110V), and the life battery directly provides 12V electricity. When 220V electricity is required, an external lithium battery power supply must be used. Or convert the 12V electricity of the life battery into 220V electricity through the charging inverter.
Electricity standards for RVs: Electricity consumption varies from place to place. Europe is 230V, China is 220V, and the United States and Japan are 110V. European RVs can use 220V electrical appliances through the conversion plug; American and Japanese RVs can only use 110V electrical appliances. Many imported RVs output current through the plug in the RV other than 220V, and need to convert the voltage through an inverter.
Sources of electricity for RVs
(1) Charging at the campsite, each RV has a mains port, which can be charged directly at the campsite;
(2) During driving, the vehicle generates electricity by itself and charges the battery;
(3) The RV is equipped with a generator, which can recharge the battery in the field.
How to use RV lithium battery
1. If the battery has peculiar smell, noise, smoke, or even fire, all personnel will leave the scene as soon as they notice it, and call the insurance company immediately.
2. Battery storage: The environment for storing lithium batteries should be kept dry. It is not allowed to put the battery in a place where water may leak, such as on the ground, etc., to avoid short-circuiting of the battery pack due to the leakage of heating and the rain from the window.
3. In case it rains, water will leak into the battery and cause a short circuit. It is not allowed to place various flammable, combustible, and explosive materials next to the battery. Once these things have problems, they will react more violently with the battery. The old and new batteries must be stored separately. Beside the battery, there must be a fire extinguisher so that a fire can be quickly extinguished.
4. When the battery is not used for a long time, be sure to turn off all power sources on the RV and check whether the battery still has discharge current! If you don’t turn off all electrical appliances, the battery can be exhausted even if the power is very small. Although the battery has built-in over-discharge protection, long-term zero-power storage will seriously affect the battery life.
Electricity for RVs is one of the most important things in the RV usage class. More power saving skills need to accumulate experience in actual use and communicate with experienced riders. Of course, the safe use of electricity is always the most important thing. Always pay attention to the electricity consumption in the RV, especially when using high-power electrical appliances.
At present, most of the car batteries on the market have a lifespan of about 2 years and a one-year warranty. If they exceed 3 years, they need to be checked frequently to avoid problems at any time; less than half a year means that the circuit and power generation system of the RV has one or another failure and needs to be repaired. It is a good habit to check the generator frequently. Turning off the on-board electrical equipment before turning off the RV is also necessary to maintain the battery. When the parking engine is not working, it is of great benefit to the battery to minimize the use of electrical equipment for in-vehicle entertainment.
The electric energy configuration of the RV can be adjusted according to your own needs. Whether it is a lithium battery or a lead-acid battery, enough capacity can support the relative use time of the electrical appliance. I personally think that a battery capacity of 600-1000 Ah is more appropriate. The entire electrical system on the RV is actually a small power grid consisting of power stations + substations + electrical equipment. Therefore, the circuit is relatively complicated. If the electrical system of the RV fails, it is best to find a professional to solve it.
