Description
technical field [0001] The invention relates to the field of electric vehicles, in particular to a high-efficiency and energy-saving battery life control system for electric vehicles. Background technique [0002] Now electric vehicles are becoming more and more popular, but battery life is the biggest obstacle encountered in the promotion of electric vehicles, and it is also difficult for domestic electric vehicle technology to make major breakthroughs. The electric vehicle has a set of controllers that control the working state of the electric motor. The controller controls the speed of the electric motor to rotate according to the operation of the driver stepping on the gas pedal. The battery is the power source for the motor to rotate, but the voltage decay of the battery is non-linear. When the battery is fully charged, the voltage decreases slowly. When the battery is partially consumed, the voltage decays faster and faster. The cruising range is an important symbol t...
