Embodiment
Below with reference to accompanying drawing and practical circuit structure of the present invention and beneficial effect are elaborated.
As shown in Figure 4, the invention provides a kind of energy-storage system that is used for hybrid vehicle, comprise at least one battery pack 1, at least one capacitive branch 2, battery charge control circuit 3 and battery discharge control circuit 4, introduce respectively below.
Each battery pack 1 is in series successively by some batteries, and described battery can be lead-acid battery, Ni-MH battery, lithium battery etc., can be simultaneously with reference to shown in Figure 5, and each battery pack 1 is relation parallel with one another, only adopts a battery pack in the present embodiment; And generator 5 (as permanent magnet generator, switch reluctance generator etc.) also is connected the two ends of battery pack 1, is used for charging for battery pack 1 and capacitive branch 2 in case of necessity.
Situations such as each capacitive branch 2 all is to be in series successively by some super capacitors, has been to use two capacitive branch 2 among this embodiment, concrete quantity visual automobile model and determining, and all capacitive branch 2 are relations parallel with one another.
Battery charge control circuit 3 is connected between the input of generator 5 and battery pack 1, is used to control the charging of 5 pairs of battery pack 1 of generator; Specifically, battery charge control circuit 3 comprises charging IGBT 31 (also can use contactor certainly), charging diode 32, charging process device and battery voltage detection circuit.Charging IGBT 31 is connected between the input of the feeder ear of generator 5 and battery pack 1, and the battery voltage detection circuit (not shown) is connected with battery pack 1, is used to detect the SOC parameter of battery pack 1, and sends into charging process device (not shown); Described charging process device is according to the on off state of battery SOC control charging IGBT 31, the control of charging.
Battery discharge control circuit 4 is connected between the input of the input of battery pack 1 and capacitive branch 2, be used to control battery pack 1 and whether discharge, described battery discharge control circuit 4 comprises discharge IGBT 41 (also can use contactor certainly), discharge diode 42, discharge process device and super capacitor voltage detecting circuit.Wherein, discharge IGBT 41 is connected between the input of the input of battery pack 1 and capacitive branch 2, the corresponding connection of super capacitor voltage detecting circuit (not shown) with the two poles of the earth of capacitive branch 2, be used to detect the terminal voltage of capacitive branch 2, and send into discharge process device (not shown), and the discharge process device is controlled the closed of discharge IGBT 41 or is disconnected action according to the magnitude of voltage of super capacitor, thereby controls the break-make of its place circuit, the control of discharging.
As shown in Figure 5, be the circuit connection diagram of a preferred embodiment of the present invention, wherein, capacitive branch 2 is to use the super capacitor of 16 same model, is divided into two groups, composes in parallel after the series connection respectively again; In the figure, the purpose of discharge diode 42 is to prevent that battery pack 1 from participating in braking energy and reclaiming, prevent that capacitive branch 2 is directly to battery pack 1 charging; In the present embodiment, also between the negative pole of discharge diode 42 and discharge IGBT 41, be connected in series a fuse 43, the purpose of this fuse 43 is drive motors torque control fails when avoiding battery pack 1 to participate in electric weight output, avoids battery pack 1 overload output and damage battery pack 1 (this is first kind of battery pack output protection mode); And the purpose of discharge IGBT 41 has three: one, and when avoiding the voltage of capacitive branch 2 to be lower than battery pack 1, battery pack 1 directly is communicated with capacitive branch 2 and causes battery pack 1 overload output; The 2nd, judge the power output size of battery pack 1 by the drive motors current detecting, if power output is excessive, then cut off battery pack 1 output, thereby avoid battery pack 1 overload output (this is second kind of battery output protection mode) by IGBT 41; The 3rd purpose is that the voltage at capacitive branch 2 cuts off IGBT 41 when being higher than the ceiling voltage of battery pack 1, to guarantee battery pack 1 no overvoltage risk.
