How to Maintenance Polymer Lithium Battery Charge and Discharge

Author: Source: Datetime: 2016-10-18 18:06:22
With the highly developed field of new energy lithium batteries using as the storage batteries of solar powered portable generator is increasingly being used. Capacity lithium polymer battery inside is a large, small, lightweight lithium battery. Because the flexible polymer batteries are a form, so can not produce in the course of the collision, and make sharp objects collision cell.

Polymer lithium-ion battery test conditions at a temperature of 20 ± 5℃, standardized tests are required before the test battery is fully discharged, between 45-85% relative humidity of the air, this is the best test for polymer batteries good standard conditions, it's good for using in portable solar power generator.

In order to ensure safety during use polymer battery, the charging process takes a constant current constant voltage charging, the charging current must be a monomer 1C5A, the charging temperature range is between 0 ~ + 45℃, so in general do not worry about the South limit temperature conditions, due to differences in regional and northern regional consumers polymer used in the winter to use in particular. At the same time, the charging voltage of the polymer can not exceed 4.23v.

Whether general or large-capacity lithium polymer battery, the charging process should pay attention, and discharge of the battery can't be ignored. In general, thedepth of discharge, the shorter battery life. Discharge current increases, the shorter the battery life. LifePo4 batteries can cope with short-term high-current electrical exile, but if the depth of discharge, the polymer will affect lifePo4 batteries life.

During the long-polymer battery is not used, the battery itself may cause some kind of over-discharge state. To prevent this from happening, should give lifepo4 during long periods of use periodically charged, the battery voltage is maintained at more than 3.0v, advance to prevent over-discharge because the battery performance and lead to loss of function.
