1. Adding lithium battery can solve the power problem of RV, right?

2. How much battery do I need to add to meet the daily power consumption?

3. Is solar panel necessary?

This is the concern of the car friends. In fact, the electric energy system of the RV is not so simple. Today, Huayu Zhihang takes you to get up and re understand the "electricity" for the RV.

I. difference between electric power for motor homes and residential buildings

There is only "power distribution" and "electricity consumption" in the house, while the RV is a complete electric energy system, which is divided into "three parts and seven links". There are three parts: power generation, power storage and power consumption; seven parts: power generation, transmission, charging, power storage, inverter, power distribution and power consumption.

II. I don't have enough electricity for the RV. How to solve this problem?

Under the background that the development camp of China's RV industry is relatively lagging behind, we are facing a very serious problem of "insufficient electricity". So after we understand the "three plates and seven links" of the electric energy system of RV, we have a direction for the transformation of the electric energy system of RV.

3. Barrel effect -- electric power system balance theory of RV

"Barrel * short board determines the water holding capacity of the whole barrel". Three boards and seven links of the electric energy system of the RV can not be short board, and any link short board will cause waste in other links. The purpose of the electric energy system transformation of RV is to eliminate the short board and seek balance

IV. "how many barrels do I need?" Use "electricity consumption" to push back "wooden barrel"

So how to match the whole electric energy system of our RV? How many "buckets" is suitable? The better the theoretical "wooden barrel" is, but considering the cost performance, overall space utilization, light weight of RV and other factors, the "wooden barrel" should be made? Moderate, enough.

V. learn to use electricity reasonably

The electric energy of RV is limited. In order to pursue more cost-effective and space balanced utilization ratio, we should learn to use electricity reasonably. The rational use of electricity follows the following basic principles: "power, frequent use of electrical appliances, try to use alternative energy". After all, the RV is not at home. Although the RV can bring us convenience during travel, some of its functions and disadvantages cannot be avoided. We can only save electricity as much as possible.

There is also a principle for rational use of electricity: "live within your means" and do not overdraw electricity. The electric energy of RV is relatively limited, so it's very important to save and live within the budget! For ordinary lead-acid batteries, two or three times of over discharge is enough to make the batteries completely useless. Therefore, it is necessary to choose the lithium iron phosphate battery with relatively good performance to price ratio as far as possible.

Vi. what are the specific projects and contents of the electric energy system transformation of motor homes?

The electric energy system design of the finished RV mostly imitates the camp popularization mode of developed countries. So once we leave the camp, it is difficult for the RV to meet the basic electricity demand. The transformation of power system is particularly important. In the transformation of electric energy system, it is necessary to make rational use of new energy; secondly, it is necessary to make up the shortcomings and break through the bottleneck.

The lithium iron phosphate battery pack for caravans is composed of: cell pack, overcharge and over discharge protection system, monomer balance control system, box, etc. Some manufacturers have also installed the core maintenance interface of the temperature protection system. The lithium iron phosphate battery pack for caravans has many advantages, such as safety, reliability, volume, light weight, no overcharge, long service life and so on. As a new energy, it has been widely used in the field of electric energy for caravans. Perfect solution to the "storage" link of electric energy system of RV.

As a kind of clean energy, solar panel can make rational use of the roof space, reduce the heat radiation in the car, and continuously convert the light energy into electric energy. Although it seems that the power of "zero deposit and lump sum" generation is not good, the continuous accumulation of quantitative accumulation cannot be seen. Especially important for battery maintenance charging! It can effectively extend the battery life.

7. Of the four links, * easily neglected, two links are "transmission"? "Distribution"? The selection of voltage circuit diameter and line loss and other factors make the transformation of RV transmission line have a lot of space. The bottleneck of switch and relay in the control distribution circuit often exists in many finished RV, and there are many optimization points in these two links. In the upgrading, the goal should be to reduce "running, emitting, dripping and leaking".

In addition, the selection of charger, inverter, solar controller and many other equipment is also very important. It can also effectively eliminate the short board and improve the water holding capacity of the "barrel".

In a word, only by forming good habit of using electricity and supporting scientific and reasonable electric energy system can we ensure the quality of RV living.
