Technical Field
[0001] The present invention relates to the technical field of battery replacement for electric vehicles, and in particular to a battery mounting structure and battery replacement method for an electric two-wheeled vehicle. Background Art
[0002] Electric vehicles use batteries as their energy source, converting electrical energy into mechanical motion through controllers, motors, and other components, controlling the current flow to change speed. Power batteries are crucial as the energy source for electric two-wheeled vehicles. However, existing batteries are installed in a battery box within the vehicle frame, forming an integral part of the vehicle frame. This prevents quick battery replacement and creates issues like range anxiety, charging anxiety, and low-temperature endurance anxiety. For example, while a motorcycle can be refueled in just a few minutes at a gas station, an electric motorcycle can take six to eight hours to fully charge at a charging station. This inability to quickly recharge the battery impacts user needs.
[0003] Among them, the removable battery structure provides the idea of replacing the power battery. However, due to the heavy weight of the power battery, it is inconvenient to operate.
