For those who like long-distance self driving tours, it is very important to have a suitable RV, and the use of RV is often accompanied by power problems? At present, the lithium iron phosphate battery specially used in the market is not common, so it is difficult to know which brand of battery is better. So how do you know about the lithium iron phosphate battery of the RV?

The most important factor for the quality of lithium iron phosphate battery is the quality of the battery cell. The performance grade of the battery cell basically determines the overall performance of the lithium iron phosphate battery for recreational vehicles.

At present, the battery cells of the RV lithium iron phosphate battery mainly include the square aluminum shell battery cells, the cylindrical steel shell battery cells and the aluminum plastic film soft pack battery cells. From the perspective of the same capacity, the soft pack lithium iron phosphate battery cells in these three types of battery cells are much lighter in weight and volume than the other two types. For long-distance travel, the lighter the items you carry, the better. The other two types of batteries are similar, but when making large capacity single cell, the square aluminum shell cell is superior to the cylindrical steel shell, and the soft bag is better.

Now let's see how much electricity the house car consumes in a day:

1. The 21 inch TV has a power of about 50 watts. It is estimated that it will be used for 10 hours a day, and the cumulative power consumption will be 500 watts, about 0.5 kilowatt hours

2. The 90 liter refrigerator can be used all day, and the accumulated power consumption will not exceed 0.5 ℃. (It is generally recommended to use an intermittent stop so that the starting time of the refrigerator can be controlled and will not exceed 0.2 ℃ in a day)

3. A 100 watt laptop (generally 60 watt) is expected to run for 5 hours a day, consuming 500 watts of electricity in total, about 0.5 kilowatt hours.

4. The rice cooker with a capacity of 4L and a capacity of about 800W is expected to be used twice a day for half an hour. The accumulated power consumption is 400W, about 0.4 kWh.

5. The 900 watt electric pressure cooker is expected to be used twice a day for half an hour, with a cumulative power consumption of 450 watts, about 0.45 kilowatt hours.

6. The 800 watt electric water bottle, with a volume of 4 liters, is expected to be used three times a day for 5 minutes each time. The cumulative power consumption is 200 watts, about 0.2 kilowatt hours.

7. The 10 watt LED lamp, based on the quantity of 3, can be used for 5 hours a day. The accumulated power consumption is 150 watts, about 0.15 degrees.

8. The 500W resistance wire electric furnace (electromagnetic furnace is not recommended, with high power and power consumption) is expected to be used twice a day for 20 minutes each time. The cumulative power consumption is 350W, about 0.35 degrees.

9. According to the air conditioner of one power, it is about 1000 watts for an hour. If you turn it on for 5 hours, you need to consume 5 kilowatt hours of electricity.

Of course, these are just some of the RV appliances. There are many places where the RV needs electricity, so I won't list them all. Based on the above data, it is estimated that if the motorhome battery uses the traditional lead-acid battery, the weight of the battery is very large. Although the steel shell or aluminum shell lithium iron phosphate battery will become much lighter, it is still not as light as the soft wrapped lithium iron phosphate battery. Under the same power demand, it may be necessary to prepare two to three lead-acid batteries, while lithium iron phosphate batteries only need one. Of course, in terms of price, lithium iron phosphate batteries with good performance and quality are 2 to 3 times more expensive than lead-acid batteries, but in normal use, their service life is more than twice that of lead-acid batteries.

When purchasing a lithium iron phosphate battery, you should be alert to whether the battery cell you are purchasing is a cascade cell. The price or quotation of this type of battery is generally half or less than that of a new cell. The lithium iron phosphate battery made of this type of cell has no feeling at the beginning of use, but after a short period of use, it is easy to see rapid capacity decline, that is, the service time of the battery is shortened.
