The specific embodiment
As shown in Figure 1, the battery-driven car that a kind of Hybrid-electric carrier of the present invention drives is made of a battery-driven car (not shown), be provided with drive motor 1 in the described battery-driven car, frequency-variable controller 2 and lead-acid battery group 3, described drive motor 1 is connected with frequency-variable controller 2, frequency-variable controller 2 is connected with lead-acid battery group 3, wherein, described frequency-variable controller 2 is connected with a speed setter 4 and a braking force setter 5 respectively, be connected in series with a total drive controlling switch 6 between described frequency-variable controller 2 and the lead-acid battery group 3, be connected in series with a lead-acid battery master cock 7 between described total drive controlling switch 6 and the lead-acid battery group 3, described frequency-variable controller 2 is connected with a super capacitor group 8 by total drive controlling switch 6, described super capacitor 8 is in parallel with lead-acid battery group 3, be connected in series with a super capacitor master cock 9 between described total drive controlling switch 6 and the super capacitor group 8, described super capacitor master cock 9, lead-acid battery master cock 7 all is connected with a change over controller 10 with total drive controlling switch 6.
Further, described drive motor 1 is a frequency-conversion alternating current motor.
Further, described speed setter 4 is foot-operated speed setters.
Further, described braking force setter 5 is foot-operated braking force setters.
As shown in Figure 2, when battery-driven car needs to quicken in operational process, during startup, provide information by foot-operated speed setter 4, frequency-variable controller 2 sends and promotes big current drives electrical motor, battery-driven car quickens, starting current is taken from total loop, the total loop electric current is the electric current sum of super capacitor group 8 and lead-acid battery group 3, wherein, super capacitor group 8 provides enough big electric current, moment is about more than 95%, in order to produce very big drive torque, and lead-acid battery group 3 only provides a spot of electric current, this process has made full use of 8 moments of super capacitor provides the ability of big electric current, thereby has reduced the burden of lead-acid battery group 3, has prolonged the life-span of lead-acid battery group 3 effectively.Because the burst current of super capacitor 8 provides, and makes super capacitor group 8 and lead-acid battery group 3 will have the moment of voltage slightly to fall.Arrow among Fig. 2 has been represented sense of current.
When tending to be steady of foot-operated speed setter 4 to provisioning request, be that the operator is when requiring the stable speed operation, the electric current distribution of super capacitor 8 and lead-acid battery group 3 tends to balance, because super capacitor group 8 is different with the internal resistance of lead-acid battery group 3, therefore according to the equipotential principle, voltage is identical, the electric current difference.
As shown in Figure 3, when the operator of battery-driven car provides the brake request signal by foot-operated braking force setter 5, variable frequency drives 2 provides an oppositely directed electric current, motor voltage is opposite with sense of current, in order to drive motor 1 is braked, at this moment electric current of transducer driver 2 and reverse during operational process, at this moment braking current is very big, electric current is directly proportional with the moving velocity of battery-driven car at that time, if at this moment there is not the existence of super capacitor group 8, will inevitably cause 3 damages of lead-acid battery group, the energy feedback can't realize.In the present invention; super capacitor 8 has played the effect that reclaims instantaneous large-current, macro-energy; at this moment; almost the energy recovery more than 95% is in super capacitor 8; and the electric energy that has only fraction is recovered into lead-acid battery group 3; recovering effect obviously and has effectively also played the effect of protection equally to battery pack.Then, the voltage of lead-acid battery group 3 is tending towards balance once more, because the voltage of lead-acid battery group 3 is gradual processes, has so just prolonged the service life of battery pack.Arrow among Fig. 3 has been represented sense of current.
When battery-driven car returned to smooth operation, the electric current of the outgoing current of super capacitor 8 and lead-acid battery group 3 tended to be steady once more.
