Colloid storage battery in ballooning, how should solve-Power Kingdom
We in the maintenance work, summed up the solution for colloidal battery to bulge.
On the one hand, according to the properties of the gel battery, battery charging of the switch power management software to do the following changes: first, in order to shorten the filling time, avoid the battery overcharge cause bloating, reset all floating conversion conditions, the original set current value 10 ma/Ah as a condition of all charge changed to when the current value reduced to 20 ma/Ah system will be automatically converted into floating operation.
Second, the temperature sensor of switch power supply received battery cabinet, made of switch power supply can float charging voltage adjustment in accordance with the environmental temperature.
Increase over temperature protection, when the temperature reaches 40 ℃ system automatically converted into floating operation, avoid caused by continuous large current charging battery ballooning.
Third, in order to prevent the battery overcharge, shorten the charge time, will have sufficient protection from 18 hours to ten hours (
All charge time setting is to prevent the battery thermal runaway, when both charging flow cannot to set all floating current value, system forced into floating within the given time)
Four, extend the timing cycle, avoid frequency large current charge.
Timing are filling cycle to its original value changed to 100 days, 180 days.
Five, cancel the stream of switch power supply function, avoid battery charging ballooning.
Through the above changes to the battery parameters, mainly in the meet of battery sufficient electricity, avoid switching power supply for gel battery charging.
On the other hand, in order to prevent the quality problem of the safety valve to exhaust, daily inspection to strengthen the inspection of the relief valve should be paid attention to, while requiring battery manufacturers to further improve the quality of the safety valve testing and manufacturing process, to ensure the safety valve to open after threshold can normal open valve exhaust.
Through the above process, after a period of observation, the gel battery has not appear shell bulge phenomenon, run in the normal state.
To sum up, in the south of the high temperature environment, should be based on the characteristics of gel battery, in the case of guarantee adequate storage battery electric, setting up reasonable charge turned floating threshold current value and charge time, avoid the battery overcharge ballooning gel battery shell problems, at the same time, must complete the battery over temperature protection, and to strengthen the inspection of the relief valve, found that the problem should be timely rectification, in order to improve the efficiency and service life of the gel battery.
In this way, make the gel battery power saving, reducing lead and acid get the full play to the advantages of the environmental pollution.
