[0002] With the increasing popularity of automation equipment, in order to improve work efficiency and increase production capacity, working equipment will be in an uninterrupted working state, so the uninterrupted power supply of working equipment is particularly important; PACK module is the backup power supply of working equipment. In order to ensure that the PACK module is in good working condition, the PACK module needs to be tested for energy storage battery clusters. Generally, the charging and discharging of the PACK module will use a charging and discharging cabinet that matches the voltage, current, and internal resistance.

[0003] Therefore, it is necessary to provide a PACK module leveling optimization system that can stabilize the PACK module current to achieve voltage leveling for different PACK modules. Utility Model Content

[0014] Beneficial effects of the utility model:

[0015] By setting a controller, the controller monitors the voltage of the PACK module. If the voltage of the PACK module reaches the charging protection threshold, the controller disconnects the PACK module to power the electronic load. When the PACK module is fully charged, it will not suddenly disconnect the current to other PACK modules, causing the charging current of the remaining PACK modules to be affected; the charging and discharging cabinet only needs to set a fixed charging power, which reduces the number of charging and discharging cabinets, reduces costs, and improves work efficiency; through the use of electronic loads, the electronic loads can adjust the voltage to adapt to the PACK module, so that the PACK module can have a stable voltage, which greatly reduces the difficulty of leveling the PACK module and improves the charging and discharging efficiency and stability of the PACK module.

[0020] In order to make the purpose, technical system and advantages of the embodiments of the utility model clearer, the technical system of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] In some embodiments, Figure 1 As shown, a PACK module leveling optimization system includes: a charging and discharging cabinet 100; by setting the charging and discharging cabinet 100, the charging and discharging cabinet 100 provides power for the equipment, and the charging and discharging cabinet 100 can stably control the current and power to provide current charging for the PACK module 130; a plurality of bus bars 110, which are electrically connected to the power supply end of the charging and discharging cabinet 100 respectively; by setting the bus bar 110, the bus bar 110 can collect and redistribute the electric energy of the charging and discharging cabinet 100 to the PACK module 130, and the bus bar 110 can collect and redistribute the electric energy of the charging and discharging cabinet 100 to the PACK module 130. 10 is a phase bus 110 with insulation protection, which has higher protection performance and prevents workers from accidentally touching live objects and causing injuries to the workers; a plurality of controllers 120, the power supply end of each controller 120 is electrically connected to the corresponding bus 110, and its two output ends are respectively connected to the power supply ends of the PACK module 130 and the electronic load 140 to form a charging and discharging circuit; wherein the controller 120 is used to control the on and off of the PACK module 130 and the electronic load 140. By setting the controller 120, the controller 120 monitors the voltage of the PACK module 130. If the voltage of the PACK module 130 reaches the charging protection threshold, the controller 120 disconnects the PACK module 130, thereby supplying power to the electronic load 140. When the PACK module 130 is fully charged, the current to other PACK modules 130 will not be suddenly disconnected, causing the charging current of the remaining PACK modules 130 to be affected; the charging and discharging cabinet 100 only needs to set a fixed charging power, which reduces the number of charging and discharging cabinets 100, reduces costs, and improves work efficiency; through the use of the electronic load 140, the electronic load 140 can adjust the voltage to adapt to the PACK module 130, so that the PACK module 130 can have a stable voltage, which greatly reduces the difficulty of leveling the PACK module 130 and improves the charging and discharging efficiency and stability of the PACK module 130.

[0024] A voltage threshold is set in the PACK module 130; by setting the voltage threshold, the voltage threshold is adapted to the charging saturation voltage of the PACK module 130. When the PACK module 130 reaches the voltage threshold, the controller 120 can disconnect from the PACK module 130 to pass current into the electronic load 140.

[0027] The voltage, current, internal resistance, power and sampling accuracy of the electronic load 140 are selected according to the charging and discharging requirements of the PACK module 130; by adjusting the power of the electronic load 140, it can adapt to different PACK modules 130, and replace the battery after the PACK module 130 is fully charged, so that the current of the remaining PACK modules 130 remains unchanged.

[0028] The positive electrode of the controller 120 is connected to the positive electrode of the bus 110 , and the negative electrode of the controller 120 is connected to the negative electrode of the bus 110 , so that the output end of the controller 120 and the bus 110 form a loop.

[0029] The positive pole of the busbar 110 is connected to the positive pole of the charging and discharging cabinet 100 , and the negative pole of the busbar 110 is connected to the negative pole of the charging and discharging cabinet 100 . The busbar 110 and the output end of the charging and discharging cabinet 100 form a loop.

[0030] The controller 120 is connected to the charging and discharging cabinet 100 in parallel; the positive and negative poles of the controller 120 are connected in parallel, and the resistance of each branch connected to the controller 120 is not much different, so the current divided by each branch on the controller 120 is almost the same, so that each PACK module 130 can be provided with a stable and identical current and voltage to charge the PACK module 130.
