Embodiment 1

[0041] see figure 1 As shown, a distributed all-on-line battery charge and discharge test equipment includes: a DC-DC host power supply 1, a control unit 2, a safety protection circuit 3, an automatic current-limiting charging and equipotential connection safety control circuit 4 , a constant current discharge load intelligent control circuit 5, a discharge load circuit 6, a second safety protection circuit 10, a positive and negative polarity conversion switch 11, a DC-DC converter 12, a battery pack online test switch 13, And a battery pack online test conversion control circuit 14. The control unit 2 further includes an MCU unit 21, and a current / voltage data acquisition and conversion control circuit 22 connected to the MCU unit 21, a battery unit voltage detection device 23, a data memory 24, and a remote communication circuit. 25. LCD display and keyboard input 26;

[0042] The safety protection circuit 3, the automatic current-limiting charging and equipotential conne...

Embodiment 2

[0064] like figure 2As shown, the structure of the second embodiment is basically the same as that of the first embodiment above. The difference between the two lies in: the DC-DC converter 12, the automatic current-limiting charging and self-restoring equipotential connection safety control and protection circuit 4, and the safety protection The output of the parallel connection of the circuit 3 is connected to the input of the positive and negative polarity conversion switch 11 of the power supply. The two positive and negative connection common terminals (positive pole D+1 terminal, negative pole D-1 terminal) are opposite in polarity to the corresponding terminals in the first embodiment. For other structures, reference may be made to the description in the first embodiment above, and will not be repeated here.

[0065] Please refer to Image 6 In the second embodiment, the first connecting terminal A is positively connected to the positive pole of the online working pow...

Embodiment 3

[0067] like image 3 As shown, the distributed all-on-line battery charge and discharge test equipment of the third embodiment is the same as the structure and connection terminals of the first and second embodiments above, the difference is that in the third embodiment, the DC-DC conversion The device 12, the DC-DC host operating power supply 1, and the constant current discharge load intelligent control circuit 5 all have the characteristics of forward and reverse polarity power supply. It can realize the best and safe operation mode, and is applicable to the charging and discharging maintenance test of online battery packs with different positive and negative communication power sources, and the working connection method is the same as that of the above-mentioned embodiment 1 and embodiment 2, no matter the working power source is Whether the positive pole or the negative pole is grounded, when the equipment is performing online maintenance and testing, only the working gro...
