Description

Technical Field

[0001] The invention relates to the technical field of power generation devices, and in particular to a lever generator range extender. Background Art

[0002] An electric vehicle is a vehicle that uses an on-board power source as a power source, drives the wheels with an electric motor, and complies with various requirements of road traffic and safety regulations. Since its impact on the environment is relatively small compared to traditional vehicles, its prospects are widely optimistic. However, in the prior art, electric vehicles must be charged at a specific charging pile or a location with a specific charging device. When charging with a charging pile, if the electric vehicle prompts that the battery is insufficient, it is necessary to find a charging place before charging, which is inconvenient to use, especially in unfamiliar places where the charging pile cannot be found in time and accurately, which may result in failure to charge in time, resulting in the electric vehicle being unable to be used normally. Therefore, an on-board range extender is installed on the existing electric vehicle. At present, the general type of the range extender power generation system is that the engine is directly connected to the generator for power generation, and the corresponding motor is a low-speed and high-torque motor, which makes the cost higher, and especially in the field of high-power power generation such as large mining vehicles or engineering machinery, under the premise of ensuring that the engine's efficient speed remains constant, the corresponding engine torque must be increased, so the torque demand of the corresponding generator must also be increased synchronously, which leads to a significant increase in both the size and cost of the corresponding generator, which does not meet the low-cost requirements and is not in line with the industry development trend.
