How to Fix Motorhome Power Supply Problem; what is the appropriate size camper battery?

How to solve the problem of power supply for motorhomes? Generally, motorhomes have their own power supply and solar power generation device. If that's not enough, passengers can bring a generator.

Most domestic consumers are relatively unfamiliar with RVs, but many consumers also like to travel by RV.

Traveling in a motorhome is a very pleasant experience.

The camper has a bed inside and can also cook. The camper can meet the needs of living and living.

Most RVs are equipped with solar power generation devices, and the generator can also charge the battery while the RV is running.

If you feel that this is still not enough, you can bring a generator.

Generators burn fuel oil. As long as there isgasoline or diesel, you can use electricity.

There are many types of motorhomes. Some large motorhomes are modified to fit the chassis of passenger cars. The price of these motorhomes is very high.

Some small campers are modified according to the chassis of pickup trucks, and these campers are relatively cheaper.

There are also smaller motorhomes that are modified on the basis of vans. Although this type of motorhome is small, it is nevertheless more practical to travel on urban roads.

If you are interested in motorhomes, you can experience them if you have the chance. It's great to travel in a campervan.

When using a motorhome, be sure to pay attention to electrical safety and fire safety. Always lock the door when sleeping in your car.

What is the sizesuitable for a motorhome battery?

Motorhome batteries on the market are generally 200Ah, 12V standard, using lithium batteries. Regarding the advantages and disadvantages of using lithium batteries in motorhomes, here is a detailed analysis.

1. Advantages of lithium batteries:

Compared with traditional batteries, lithium batteries have higher charging efficiency and can be fully charged within a few hours, they have high energy storage and can be charged; charged once used for several months; small size and light weight, easy to carry and replace.

2. Disadvantages of lithium batteries:

Lithium batteries are less safe and may explode under special circumstances; they are more expensive than traditional batteries. Maintenance costs are higher.

In a wayGenerally speaking, the most commonly used electrical appliances in motorhomes are air conditioners, induction cookers and water heaters. These electrical devices are relatively powerful and consume a lot of electricity. Some motorhome owners are not satisfied with the vehicle battery capacity and privately replace it with a large capacity 400 Ah or even 1000 Ah battery. However, it will also increase the weight of the vehicle and improve the fuel consumption of the vehicle. Moreover, if the quality of the modified battery is not up to standard, it will also lead to a series of safety hazards.

The camper battery capacity is strictly calculated by engineers when the car leaves the factory. Under normal circumstances, we should not change its configuration at will. (Photo/Text/Photo: Q&A) @2019

Some RVsManufacturers advise againstcar owners to install lithium batteries. For what ?

If the voltage of a 600 Ah lithium battery is 3.7 V, 600 × 3.7 = 2220 Wh, 2220 ÷ 1000 = 2, 22, the voltage of 3.7V can store 2.22 kilowatt hours of electricity. .

Battery refers to a cup, tank or other container or part of a composite container that contains an electrolyte solution and metal electrodes to generate electric current. This is a device that can convert chemical energy into chemical energy. electric energy. It has positive and negative poles. With the advancement of technology, batteries generally refer to small devices capable of producing electricity. Like solar cells. Battery performance parameters mainly include electromotive force, capacity, specific energy and resistance.

The use ofbattery as a power source can achieve stable voltage, stable current, stable power supply for a long time and little influence from the outside world. In addition, the battery structure is simple, easy to carry. and charging and discharging operations are simple and easy. It is not affected by external climate and temperature, has stable and reliable performance, and plays a great role in all aspects of modern social life.

In a chemical battery, the direct conversion of chemical energy into electrical energy is the result of spontaneous chemical reactions such as oxidation and reduction inside the battery. This reaction takes place on two electrodes. The negative active material consists of negative potential and stable reducing agents in the electrolyte, such as zinc, cadmium, lead and other active metals and hydrogen or hydrocarbons. The positive active ingredient is constituted with positive potential and stable oxidants in the electrolyte, such as manganese dioxide, lead dioxide, nickel oxide and other metal oxides, oxygen or air, acids containing oxygen and their salts, etc.

Electrolytes are materials with good ionic conductivity, such as aqueous solutions of acids, alkalis and salts, non-aqueous organic or inorganic solutions, molten salts or solid electrolytes. When the external circuit is disconnected, although there is a potential difference (open circuit voltage) between the two poles, there is no current and the chemical energy stored in the battery is not converted into electric energy. When the external circuit is closed, current flows in the external circuit due to the potential difference between the two electrodes.

Why RV Renovation Factories Like to Install Lithium Batteriesithium? In order to avoid any misunderstanding about the modification industry, we still need to break this question down and break it down into a few points!

Why are RV factories avoiding lithium batteries? RV conversion shops don't like to install lithium batteries. For reference

1. There are security issues. Although few people have seen lithium batteries catch fire, it is something like this. With 10,000 possibilities, why take the risk? Being a motorhome is not a one-time deal, you can't leave the factory, just leave it behind. Since it’s after-sales, why bother!

2. Stability issues. Lead-acid batteries are more stable than lithium batteries. Isn’t a product that has proven itself for a century a car? In addition, the loss of lithium batteries at zero temperature is even greater! Can't you use it when it's cold? Actually, this problem is also caused by lead, but it is not as serious as that of lithium batteries. By creating a constant temperature loop environment can solve this problem.

3. Cost problem. In fact, it has nothing to do with the manufacturer. Wool comes from sheep. If you choose lithium batteries, the price will naturally increase. But for users it is. Obviously, a 200,000 chassis, how do you choose something that costs 400,000? From this perspective, it can help users reduce costs, reduce hardware budgets, and fulfill orders as much as possible.

4. Technical issues. Due to the mature application of lead-acid batteries, hydropower engineers in many large factories can modify them according to user needs. But now users use 48V batteries and atlithium, and they are forced to continue learning from these masters who have worked with 12 V for half their lives. Although it may seem to the user that two modules were added, in reality they broke every system he knew.

Why do RV factories avoid using lithium batteries? RV tuners don't like to install lithium batteries. For reference

In short, there are too many reasons why modification factories do not choose lithium batteries!

But things have improved a lot recently. Before 2018, many manufacturers of RV conversions were moving away from using lithium batteries. Are you finally not giving in to the market? Although that might not be a good thing in my opinion. But current solutions are actually relatively safe.

In addition, users can choose to bring their own battery.Theoretically, as long as there are no problems with the wiring, there will be no problems with the battery on the market. The only problem is that you do it yourself, tuning won't be able to protect you!

It seems that there are now special lithium batteries for RVs, and they have started to include insurance! Although this decision is shocking, it also proves that the product is reliable and that insurance companies are not stupid... Why are RV factories avoiding lithium batteries? RV tuners don't like to install lithium batteries. For reference

Lithium battery, optional, used for base station, BYD has been disassembled, Ningde But users need to understand electricity. If your diet is the same as mine, don't worry.

The most important point is actually the cost I just mentioned, comrade! Asufficient set of lithium battery + inverter will cost 20,000-30,000 US dollars, the same price comes with a lead-acid + silent generator, and there is a surplus If it is not bad, of course it is an 800AH lithium battery + a 3000W inverter. +Solar Power Store+The Most Reliable Generator for RVs Over $20,000!
