Embodiment
The present invention is composed in parallel by one or more constant-current discharge module according to the capacity and the discharging current requirement of storage battery, connects by connection between each discharge module, and its theory diagram as shown in Figure 1.Storage battery is connected to the input switch of each discharge module, data and instruction that each discharge module sends according to the main discharge module, the input quantity of control self-resistance bar fling-cut switch is also regulated the electric current of delivering to DC converter and is regulated the battery discharging electric current to sending, and carries out discharge operation.
Fig. 2 has provided the theory diagram of single discharge module.Each discharge module mainly is made up of input switch, discharge voltage and discharging current testing circuit, microprocessor, a plurality of fling-cut switch, DC converter, a plurality of PTC thermistor bar and an a plurality of fan.PTC thermistor strip adoption low-heat new high-efficiency PTC electric heating element, volume is little, and is easy to use, but long-time steady operation, no red heat danger does not have any interference and noise pollution to human body and surrounding devices thereof, than the discharge load that is more suitable for storage battery.
During discharge, after microprocessor receives the discharging current instruction by human-machine operation and display interface or communication mode, relatively intend the nominal discharge current size of discharge current value and 1~No. 10 PTC thermistor bar and DC converter, determine the quantity and the position of the fling-cut switch that drops into by the computing or the mode of tabling look-up, and the given signal of corresponding electric current is delivered to DC converter.Electric discharge device in the course of the work, the turn-on and turn-off quantity by the control fling-cut switch realizes the coarse adjustment to discharging current, by regulating the fine setting of the given realization of DC converter discharging current to discharging current.Wherein, the discharging current of DC converter is given can directly to utilize the D/A output of microprocessor to realize, also can utilize microprocessor and external D/A converter in conjunction with realization.
Fig. 3 has provided the theory diagram of fling-cut switch and drive circuit thereof.This circuit mainly by direct current relay RL1, IGBT power switch pipe Q1, resistance R 1~R5, general-purpose diode D1, voltage stabilizing didoe DZ1, triode Q2, aluminium electrolytic capacitor C1, CBB capacitor C 2 ,+the 12V working power forms.When control signal S1 was low level, analyzing as can be known, Q1 and RL1 all were in conducting state.Because the internal resistance of relay is almost nil, so IGBT is in by short-circuit condition in the normally course of work, the electric current that flows through is zero.When fling-cut switch need disconnect, control signal S1 moment became high level, and RL1 is relevant with the characteristic of relay through this time of 10ms() about delay after shutoff rapidly, discharging current is transferred to IGBT.Simultaneously, after control signal S1 becomes high level, give electrochemical capacitor C1 charging by resistance R 1, (during this period of time can be after the burning voltage that surpasses voltage stabilizing didoe up to the terminal voltage of electrochemical capacitor C1 and the base drive voltage sum of triode Q2 by the Numerical Implementation of adjusting R1 and C1, generally can be controlled in the 100ms), triode Q2 conducting, IGBT in parallel turn-offs owing to drive signal becomes low level.In the fling-cut switch turn off process, because relay at first disconnects, IGBT flows through discharging current, makes IGBT turn-off after relay disconnects fully by the drive circuit time-delay again, avoids the relay arcing to damage.In the whole process, the heating of IGBT almost can be ignored, and has avoided conventional only necessary radiator and the venting practice during as fling-cut switch with MOSFET/IGBT.If next will open fling-cut switch, then control signal S1 becomes low level again, and relay R L1 is open-minded rapidly, and C1 is by D1 and R2 repid discharge, and Q2 ends, and IGBT is conducting rapidly also, thereby finishes the conducting control procedure.Because the relay internal resistance is almost nil, IGBT is not flow through electric current by the relay short circuit.
