Fig. 4 provides the oscillogram of the charging current controller of the embodiment of the present invention.
The course of work is described as follows:
1. holding state: after power on circuitry startup starts, control chip IC2 5. pin P3.0 and 6. pin P3.1 all export high level signal, 5. the high level signal of pin P3.0 delivers to the SD end of driving chip IC1 after D2 and comparator 339D, the output of IC1 is made not control by input LIN and HIN, output LO and HO is low level, power output pipe is all in cut-off state, before a point of oscillogram.
2. charging prepares: when the charging instruction that guidance panel produces from the 1. pin P3.4 of IC2 and 3. pin P3.5 feeding time, the 5. pin P3.0 output low level of IC2, a point position of oscillogram.After D2 and comparator 339D, make the SD of IC1 hold step-down level, IC1 output LO and HO controls by input LIN and HIN.IC2 6. pin P3.1 is high level, after the inverter of IC5, the LIN pin of IC1 is high level, HIN pin is low level, IC1 output LO exports high level signal, and drive Q2 conducting by R2, the automobile batteries of access is discharged by accumulation of energy inductance L 1, energy storage is on L1, and C1 is then charged to about 14V by D1, Q2.The HO output low level of IC1, Q1A/B ends.
3. charging starts: from a to b, section is after the To of time delay 2 μ s, IC2 6. pin P3.1 becomes low level, the LIN pin of IC1 is also low level, and HIN pin is high level, Q1A/B conducting, Q2 ends, the voltage of C1 superposes with the automobile battery voltage of access and is lifted, and adds the inductance electromotive force of L1, can obtain the voltage of about 85V, make the reliable conducting of Q1A/B, unnecessary energy returns the battery pack of charging pile by Q1A/B.After the fault offset of inductance L 1, i.e. b to c section, the battery pack of electrical pile begins through the batteries charging of accumulation of energy inductance L 1 to electric motor car.
4. current detecting: charging current detects through Hall current sensor, from 3 pin output voltage signals, is added on 3 comparators respectively.Here the model selected is C1T-100A, and maximum detection electric current is 100A, needs can select larger specification during larger electric current.Hall current sensor 3 pin when zero current export 5V voltage, and export 7V voltage during forward 100A electric current, reverse 100A electric current exports 3V voltage.Electric current increases gradually, when charging current is more than 5A, the voltage that Hall element exports is more than 5.1V, and comparator 339B exports and becomes high level to chip IC 2 7. pin P3.2 by low level, timing T1 is started, c to the d section of oscillogram after chip detection to this rising edge.
5. Current Control: d to the e of oscillogram, f to g, i to j, when charging current increases above 90A gradually, sensor output voltage is greater than 6.8V, and comparator 339A output low level is to IC2 8. pin P3.3.Chip IC 2 is after 8. pin P3.3 detects this low level trailing edge, timing T1 terminates, IC2 6. pin P3.1 exports high level, and the LIN pin of IC1 is high level, and HIN pin is low level, Q1A/B ends, Q2 conducting, the battery pack of charging pile stops to the charging of battery of electric vehicle group, and the energy of accumulation of energy inductance L 1 is discharged by Q2, continue to electric motor car charging, electric current reduces gradually.When electric current is less than 5A, the voltage that transducer exports is less than 5.1V, and comparator 339B output low level is to IC2 7. pin P3.2, after chip IC 2 detects this low level trailing edge, control chip IC2 is pin P3.1 output low level again 6., Q1A/B conducting, and Q2 ends, e to the f of oscillogram, g to h, j to k, timer T1 starts timing, start next charging pulse, so go round and begin again.
6. regulate electric current: design maximum charging current is here 90A, if reduce charging current, can according to the instruction of operation control panel, control chip IC2 when second charging pulse, according to the charging interval T1 of first pulse, proportionally reduce the T1 time, also do not reach 90A at electric current, chip IC 2 8. pin P3.3 does not also detect low level trailing edge, by the time controling IC2 6. pin P3.1 output high level of T1, start next charging pulse, charging current is reduced.
7. devulcanization negative pulse: during lead acid battery charge, sulfurization being produced on battery lead plate, affect the life-span of battery pack, therefore must eliminate this sulfurization when charging, adopt and can eliminate sulfurization to the negative pulse current of battery discharge, reclaim the pulse energy of battery discharge simultaneously.Circuit design when charging reaches 20 pulses, devulcanization of once discharging.When charging current is reduced to 5A, IC2 8. pin P3.3 ignores a trailing edge pulse detected, IC2 6. pin P3.1 continues to export high level, and the timer T1 of chip IC 2 starts timing.The electric current of inductance L 1 is reduced to zero, and after fault offset is complete, the battery pack of electric motor car starts to inductive discharge, k to the l section of oscillogram.When discharging current increases above 90A gradually, comparator 339C output low level is to IC2 8. pin P3.3, IC2 6. pin P3.1 output low level, and Q1A/B conducting, Q2 ends, l to the m of oscillogram.If charging current is not select maximum 90A, but controls smaller electric current by timer, the electric current of so devulcanization electric discharge is also according to same time T1 proportional control electric current.This devulcanization negative pulse only selects lead acid accumulator just to have at operation control panel, if select lithium battery, will skip this process, directly accesses next charge cycle.
8. reclaim devulcanization negative pulse energy: after devulcanization negative pulse reaches maximum current by inductive discharge, energy storage is in inductance L 1, IC2 is after 8. pin P3.3 detects the low level pulse trailing edge of comparator 339C, IC2 is pin P3.1 output low level 6., Q1A/B conducting, Q2 ends, and the energy of inductance L 1 turns back to electrical pile battery pack, reclaim energy, oscillogram m to n.
9. next charge cycle starts: after the fault offset of devulcanization negative pulse, the electric current of inductance L 1 is zero, the battery pack of electrical pile starts the batteries charging to electric motor car, when electric current increases above 5A, chip IC 2 7. pin P3.2 detects the rising edge of high level, T1 starts timing, enters the charging of next cycle, oscillogram n to o and o to p.
10. battery voltage detection protection: in order to prevent overcharge; and other abnormalities; ensure the normal battery of access could charge; voltage detecting circuit R16, R17 and comparator 339D detect by the battery pack of charging at any time; when voltage reach be full of electricity state or have higher voltage time; 339D produces the SD end that high level delivers to IC, and the output of control IC1 is all low level, and power output pipe is all in cut-off state.Chip IC 2 does not detect the level signal of charging current for a long time, is judged as abnormality, stops charging procedure.
