Problems solved by technology
However, the power battery needs to be converted by DC / DC to provide energy for the electric vacuum pump, and the energy is lost during the conversion.
In addition, affected by many factors such as battery charge and discharge efficiency and battery charging conditions, the total efficiency of energy recovery is limited.
[0004] Therefore, when the recovered energy is only used for battery charging, the energy recovery efficiency is not high, and the problems of reducing energy consumption of electric vacuum pumps need to be solved

The invention discloses an energy-saving braking system, and further discloses an energy-saving braking method and an electric automobile using the system or the method. The energy-saving braking system comprises an electromagnetic clutch, a vacuum pump, a vacuum pipeline (3), a gas storage tank (4) and a vehicle control unit (8). The vacuum pump is connected with the gas storage tank (4) through the vacuum pipeline (3); the electromagnetic clutch is controlled by the automobile controller (8) to be in a connection or disconnection state and can drive the vacuum pump to rotate to vacuumize the gas storage tank (4); wheels drive the vacuum pump through the electromagnetic clutch to vacuumize the gas storage tank (4), the vacuum degree required by braking is achieved or supplemented, and accordingly power consumption of the electric vacuum pump is reduced, the energy capacity of a battery is saved and the energy recovery efficiency of the electric automobile is improved.
Description
technical field [0001] The invention relates to the field of electric vehicles, in particular to an energy-saving braking system, method and electric vehicle. Background technique [0002] The insufficient mileage of electric vehicles on a single charge has always been one of the key factors restricting their development. Therefore, it is of great significance to take effective measures to save power battery energy during vehicle driving. Electric vehicles use electric vacuum pumps to provide brake boost. During driving, especially in urban areas with heavy traffic, frequent braking is required, which consumes a lot of battery energy and shortens the driving range of the vehicle. [0003] In view of this, people have designed an energy-saving system according to the characteristics of electric vehicles, which converts the energy of the vehicle into electric energy through the generator to charge the power battery when the vehicle decelerates or brakes or goes downhill.
