(1) Lithium-ion battery's verified discharge is separately discharged to the lithium ion battery UPS to examine the weight of the lithium-ion battery pack to meet the maximum uniform load, referred to as a verified discharge. The detailed approach is to select the work of the high-frequency switching power supply in the case of the maximum load, so that the lithium ion battery pack is separately discharged, so that the actual load should be loaded, all of the lithium iron ion battery pack, and the discharge is completed. Lithium ion battery pack output capacity.
(2) Enhanced floating charge operation mode management floating charge operation mode is in parallel with lithium iron phosphate ion battery pack and charging device equipment, a lithium ion battery for supporting substation DC power systems. During the floating charge operation, since the difference in the internal resistance of each lithium-ion battery, the self-discharge is different, and the actual capacity is different, and the surface is inconsistent with the end voltage. (3) The temperature of the floating charge compensates that the phosphate ion battery pack operates ambient temperature, and the UPS phosphate ion battery regards the requirements of the floating voltage will vary, and the relevant operational technical parameters of the monitor should be set to eliminate due to The inclusion of the inclination and overcharge of temperature difference.
Therefore, according to the changes in the ambient temperature, the floating voltage value must be adjusted accordingly. ⑷ balance charging In the process of operation of lithium-ion battery UPS power supply, since the self-discharge of each lithium-ion battery can cause internal resistance of individual lithium ion batteries, the end voltage is different from most lithium ion batteries, resulting in various The capacity of the lithium-ion battery is inconsistent, that is, uneven phenomenon. In order to solve such problems, the output voltage of the charging device is increased, and a larger charging current occurs in the lithium ion battery circuit.
At this time, while satisfying individual lithium ion battery capacity supplements, other lithium ion batteries are overcharged states of. .
