A suitable rv must be equipped with a electrical system to power for an unlimited travel experience. This article will explain to you of charging a rv battery.
1. The source of electricity to charging a rv battery
We know that there are many ways to charging a rv battery. Many people know that there are four charging methods, but they don't know the specific process of charging a rv battery.
Today, this article will lead you to the answers. A suitable rv must be equipped with a charging system to power all the electrical equipment in the vehicle for unlimited travel experience. This article will explain to you how to charge the rv battery.
2. The composition of rv electrical system
When selecting a battery, four main factors are considered: safety, battery life, charge and discharge performance, and volume weight. The lithium battery is widely used due to the advantages of high energy density, long life, environmental protection and high safety.
The rv has also been replaced by the original lead-acid battery to the lithium iron phosphate battery to ensure the endurance of the rv's living power. When our vehicle is in normal motion, the vehicle engine charges the engine compartment battery.
This battery is used to start the vehicle, and to power the lights, cigarette lighters, air conditioners and other vehicle appliances on the car, called the main battery. The one that provides electricity for the rv is called a life battery or a secondary battery.
● Battery isolators
The isolation charger is generally installed between the main battery and the life battery, and many people also call it a battery isolator. When the car is started and the isolation charger detects that the engine is running, charging a rv battery through the isolation charger.
Its signal port is connected to the rv engine, detects the engine status, and ensures that it will be charged when the vehicle is running, which can avoid the problem that the vehicle cannot start when the main battery is exhausted by living electricity.
Of course, the isolation charger has an isolation effect, which allows the living battery not to charge the main battery in reverse, which protects the equipment in the circuit and ensures the safety of the circuit. There are many ways to charging a rv battery, each with its own unique characteristics, let's take a closer look at these charging methods.
3. The type of charging a rv battery
● Driving charging
Driving charging refers to the process of charging a rv battery by using the kinetic energy of the rv engine when the rv is running. The advantages of this charging method are:
- Convenient and fast, no need to stop and wait, you can charge anytime, anywhere.
- Depending on the speed of the vehicle, the charging level will also vary.
- It will not have much impact on fuel consumption, is relatively flexible, and ensures charging a rv battery when driving.
● Solar charging
Solar charging refers to charging a rv battery through solar panels for rv installed on the roof of the rv. It is an environmentally friendly, energy-saving charging method that converts solar energy into electricity and charges it into the vehicle's battery.
No fuel is consumed and the cost is low. Solar charging is suitable for outdoor travel, camping and other environments, which is more suitable for long-distance travel, and can reduce the number of times rvs use generators. Its disadvantage is that this charging method is easily affected by the weather and the charging time is longer. However, it can save the cost of electricity, and there will be no noise and pollution during the charging process.
● Mains charging
Mains charging refers to the storage of electrical energy into the battery through mains power. The advantages of this charging method are convenient and fast, fast charging speed, large charging power, and not affected by the weather. But what is inconvenient is that when camping in the wilderness, you need to find mains outlets, and sometimes you need to pay extra.
● Parking charge at a fixed speed
Parking fixed speed charging refers to the charging a rv battery by stabilizing the engine speed at 2000 rpm in the parking state. This method of charging is relatively large, and can fill battery of the rv in a short time. However, this method is more suitable for special scenarios. It can ensure the power supply in the car in case of emergency, and increase safety and security.
● Add battery
The original battery of the rv is small, upgrade the battery capacity, and inprove the battery capacity. Note: The battery used in ordinary family cars is a starting battery, and it has a large starting current not the car battery voltage, and rests after starting.
The engine is responsible for driving and can be charged by the engine via a generator while driving. The battery used in the rv is a deep cycle battery, which can put the discharge amount of the battery very low without affecting life, and the number of charges and discharges is much higher than that of ordinary car batteries.
● Charging at the charging pile
It refers to the storage of electrical energy into the battery through the charging pile. The advantages of this charging method are environmental protection and energy saving, fast charging speed, and no need to consume any fuel. First of all, you need to find the charging pile.
● Generator power supply
For the generator to charging a rv battery, it can be directly understood as simple, convenient, fast and effective. Unlike the generator with the engine of the rv itself, this generator directly powers the battery used in daily use, which is more suitable for outdoor use. Some people will say that the noise of the generator is large, and the generator is also silent, and you can choose the type with less noise.
4. Effect of charging a rv battery at low temperatures
● Why the charging speed slows down while charging a rv battery in winter?
This is because the activity of lithium battery cells in an environment below 10 °C will be reduced, resulting in slow charging speed. At this time, if high-power charging is also used, not only can not speed up the charging speed, but it will cause local overheating of the battery.
● Tips for charging a rv battery at low temperatures
Try not to let the power fall below 25% in a low temperature environment, and charge the rv if possible, so as to maintain the life of the lithium battery. At the same time, we also recommend buying an rv with solar panels, which greatly increases the chances of charging a rv battery.
Lithium battery loss will affect the service life, so if you do not use the rv for a long time, it is recommended to empty the refrigerator first, and then turn off all electrical appliances on the rv. Before the power failure, try to ensure that the lithium battery power is more than 50%, and if possible, you can regularly check the remaining power and charge it on time.
To sum up, there are many ways to charge rvs, and we can choose the right way according to our needs and occasions. If the driving distance is relatively long, you can use the driving charge. If you stay outdoors for a long time, you can use solar energy to charge. If you need fast charging, you can choose mains charging.
Emergency supplementation, solving power anxiety, parking fixed speed charging is a good choice. In short, there are various charging methods for rvs, and it is very important to choose the right charging method according to your actual situation. The diversification of charging a rv battery is to solve the problem of electricity consumption and bring a better rv life experience.
