As an RV enthusiast and user, as well as an RV self-media practitioner, I wrote the most basic electric knowledge introduction for RVs, as well as the advantages and disadvantages and choices of 12V, 48V, and 400V RV life battery voltage levels. This discussion on the charging method of the RV life batteries and rv solar panels is only a reference for readers and RV enthusiasts.
Taking the 12V RV chassis and the 48V RV life battery as an example, 10 charging methods for the RV life battery are listed at this stage.
Ten ways to charge 48V RV life battery
- 12V boost module charging
Looking at the current 12V RV chassis, there are 110A, 130A, and 220A onboard generators, as well as 150A, double on-board generators. The RV factory purchases the chassis to save money, and it also uses a smaller driving charging power, which should be paid special attention to.
Advantages: The 12V driving generator can charge the 48V life battery after boosting, the principle is simple, the wiring is simple, and the operation is convenient. For the required boost and buck modules, search various electrical equipment companies on the Internet, at Ma Yun’s home, or in various self-media, or RV forums, there are also many players selling them.
Disadvantages: Using a boost or buck module, there is a problem with conversion efficiency, and the stability of the boost and buck module is also prone to problems.
- 12V inverter 110V AC after charging
Advantages: Theoretically, it is quite good. Regardless of the power frequency and high frequency, there are a lot of inverters, and the efficiency is quite high.
Disadvantages: Maybe the inverter is too expensive and the size is not small. I personally have not seen this method used by riders, but riders have discussed this charging method.
- 48V DC driving with the help of a generator for charging
Advantages: Leveraging a generator is a good thing, it can charge five kWh in one hour, and it has such a relatively high charging power. And 48V compared to 12V, the current is reduced, the heat dissipation is small, and the loss is also reduced.
