  • Off-road vehicle
    Patent number: 11685323
    Abstract: An off-road vehicle includes a vehicle body, a power system, electrical devices, an electricity storage bank, a generator, and an electric power regulator. The electric power regulator is used to regulate the voltage output from the generator to the electricity storage bank and corresponds to the electricity storage bank. The electric power regulator includes a voltage regulating chip, a switch circuit and voltage stabilizing circuit. The electric power regulator is capable of regulating the voltage output from the generator to the electricity storage bank according to the nominal voltage of the electricity storage bank, and the output voltage of the electric power regulator is greater than the bank voltage.
