It is as follows that braking energy reclaims the range of motor speeds computation process of choosing:
Recuperated energy E=K1K2K3 (E1-FS) once brakes, in brake process, car body kinetic energy decay E1 is definite value, machinery driving efficiency K1 and force of rolling friction F fix substantially, it is constant that charge efficiency K3 also can think, for motor, in braking procedure, its generating efficiency K2 changes with the variation of rotating speed and torque, and stopping distance S depends on the size of braking force and the length of braking time.
Kinetic energy E1=1/2mv2, below calculates and drops to 0 calculating by rotating speed.
(1) when drive motor rotating speed is during lower than 300rpm, E
1=0.5*18000*9
2=729kJ=0.2kWh.In the time that the horsepower output of motor is 0～30kW, the efficiency that electric energy conversion is kinetic energy is below 70%.According to the recuperated energy E=K that once brakes
1k
2k
3(E
1-FS); In removal process, along with the reduction of the speed of a motor vehicle, generating efficiency and power constantly reduce, and recoverable energy is few, inefficiency, and low speed braking can affect ABS effect.Therefore do not take during lower than 300rpm braking energy to reclaim at motor speed.
(2) when motor speed is higher than 1500rpm, E
1=0.5*18000*45
2=18225kJ=5.06KWh.
In the time that the horsepower output of drive motor is 170KW, the efficiency that electric energy conversion is kinetic energy is 92%.
With 170*0.92=156KW, generating efficiency K
2little with rotation speed change, other coefficients are amounted to by 0.8 calculation, and power also reaches 120KW, battery rated voltage 336, and charging current has reached 357A.Exceed the maximum charging current that battery bears.And braking can affect car load braking effect at a high speed, causes potential safety hazard.Therefore do not take during higher than 1500rpm braking energy to reclaim at motor speed.
Therefore, motor speed is at 1500rpm(45km/h) when above, do not carry out braking energy recovery.Drive motor only carries out braking energy recovery in 300rpm-1500rpm range of speed.
Above are only the specific embodiment of the present invention, but design concept of the present invention is not limited to this, allly utilizes this design to carry out the change of unsubstantiality to the present invention, all should belong to the behavior of invading protection domain of the present invention.
