When we buy a RV, we often ask sales a lot of questions, such as: Is the engine good? How is the interior? The size of the lithium battery, etc. In fact, these are the issues that we are more concerned about when purchasing a RV. Everyone knows that RVs are much more expensive than ordinary cars, so it is very important to choose a RV that suits your family! However, when people buy RVs, they often have some misunderstandings. For example, many friends often choose larger lithium electric cars when choosing RVs. They think that RVs with larger lithium electric cars are very convenient, but larger Is the lithium battery really that good? , Next, the editor of Topbond lithium battery will discuss this issue with you.

The necessity of RV with lithium battery

When traveling by RV, the biggest problem is water and electricity. The problem of water is relatively easy to solve. It is not so troublesome to find water. The more headache is the supplement of electricity. Some people say that the RV travels with a portable generator, doesn't it have electricity at all times? The more troublesome thing about generators is the noise. It is probably fine to use generators during the day. At night, if you still use generators to supply power, the accompanying riders will stay away from you. Of course, if you are traveling alone in an RV, it doesn’t matter how you want to use generators. , because the noise only disturbs itself. It is also more troublesome to use a generator. Every time you use it, you have to lift it up and down, and you need to connect it. It needs to be a little farther away to reduce noise. If the RV is equipped with a certain amount of lithium batteries, it will be relatively much better. Lithium battery plus inverter, there is almost no sound, the same feeling as at home.

How much capacity lithium battery is more suitable for RV

How much battery capacity the RV is equipped with mainly depends on the total power consumption of the RV. Generally, there are rice cookers, electric water heaters (boiling water), lights, TVs, audio equipment, etc. on the RV, and some RVs also have air conditioning. For general RVs without air conditioning, it is recommended that the battery capacity should be 400ah. For RVs with air conditioning, it is recommended that the battery capacity should not be less than 400ah. Generally, 600ah-800ah is better. The above battery capacity is based on the battery pack voltage of 12V.

Selection and identification of RV lithium battery

The lithium batteries we often talk about include ternary lithium batteries and lithium iron phosphate batteries. The advantages of ternary lithium batteries are high power density, and the current price is lower than that of iron phosphate. But the ternary lithium battery has two problems. First, the power decays quickly, and it drops by 30%-50% in about three years. This is the kind of mobile phone battery we use. After about three years, the mobile phone battery has to be replaced, otherwise the mobile phone will be used daily. , can't last a day. Second, the safety of ternary lithium batteries is not as good as that of lithium iron phosphate batteries. Under the collision, external force, and puncture, the ternary lithium battery is easy to catch fire and explode, but the lithium iron phosphate battery does not have this problem.

If you use an iron phosphate battery, how do you know if the battery is good or not? A simple method is the charge density identification method. It is the same battery, whichever is lighter, the lighter is better, the heavier the worse, the second-hand battery is also possible, or the battery itself is a poor quality battery. At present, the power density of good quality lithium iron phosphate batteries can be above 130, generally around 100.

Precautions for the use of RV lithium battery

1. 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 all electrical appliances are not turned off, even a small amount of power can exhaust the battery power. Although the battery has built-in over-discharge protection function, long-term zero-power shelving will seriously affect the battery life.

Recommendation: Before parking for storage, carefully check that the power is turned off and recharge the battery every three months

2. If the battery has peculiar smell, abnormal sound, smoke, or even fire, all personnel should leave the scene as soon as they notice it and call the insurance company immediately.

3. Battery storage: The environment for storing lithium batteries should be kept dry. It is not allowed to place the battery in a place where water may leak, such as on the ground, to avoid short-circuiting of the battery pack due to water leakage from the heater and water from the rain window.

The battery pack should be kept away from flammable, flammable and explosive materials, and old and new batteries should be stored separately.

Battery pack storage should have a Class D fire extinguisher and breathing apparatus.
