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.
Disadvantages: The RV market is too small, and chassis manufacturers do not develop it at all. I personally see that some players in the private sector have modified it themselves, which requires enough space in the engine compartment, and strictly speaking, unauthorized modification is illegal, and the car will lose the warranty.
- 110V AC driving with the help of a generator for charging
The advantages and disadvantages of this are similar to those of the 48V borrowed generator above. I only learned about it after a car friend left a message. I think this one he has studied is also very good.
For RV practitioners: There are fewer RV R&D personnel researching generators and inverters, and there are still more RV players. It is necessary to develop RVs. Investment is the real technology.
- Solar photovoltaic panel charging
Advantages: With the rapid development of science and technology, solar panels have been reduced from more than $7 per watt in the earliest stage to $0.5 per watt now. The price is cheap, and the installation and wiring are simple and convenient. And the power generation is also good. According to the actual measurement of the riders, the solar energy on the roof of the car is 840 watts, and the limit of power generation is 5 kWh per day.
