Off-road vehicle

An off-road vehicle comprising:

• a vehicle body;
• a plurality of wheels comprising a first front wheel, a second front wheel, a first rear wheel, and a second rear wheel;
• at least one seat disposed on the vehicle body, the seat comprising at least a driver's seat;
• a suspension system comprising a front suspension and a rear suspension, the first front wheel, and the second front wheel being connected to the vehicle body by the front suspension, and the first rear wheel and the second rear wheel being connected to the vehicle body by the rear suspension;
• a power system for providing power to the off-road vehicle disposed on the vehicle body, at least one of the first front wheel, the second front wheel, the first rear wheel, and the second rear wheel being connected to the power system, the power system comprising at least an engine;
• an operator manual control disposed on the vehicle body for manipulating the running of the off-road vehicle;
• an electrical load provided by one or more devices disposed on the vehicle body, the one or more devices comprising at least a starter motor for starting the engine of the off-road vehicle;
• an electricity storage bank disposed on the vehicle body, the electricity storage bank being connected to the electrical load, and the electricity storage bank being at least used to supply electric power for the starter motor when the engine needs to be started, and the starter motor after powered driving the engine to start;
• a generator for generating electric energy disposed on the power system, and the electric energy generated by the generator is used to supply electric power for the electricity storage bank;
