Both necessary and sufficient manner by the current set-voltage charge of the implementation of phase II trial showed that this charging method of charging more efficient, commonly used for domestic and foreign. The current charge for the end-voltage balance criterion, in theory, is consistent with the understanding that the activity should be based on positive and negative electrode material to judge the extent of the transformation. With the anode board is the conversion of the active substance, the charge current will be gradually reduced, but even if the board is negative electrode active material into after the completion of all, in theory, the charge current is still not zero, but at a lower value On the basic stabilizing. The calculation, the stable value of about 0.42mA/Ah. So, when the charge current of 1 mA / Ah ~ 2mA/Ah, and 2 ~ 3h stability in the same time, the end of that charge. At this point, charging devices are derived from the automatic shift to the state Fuchong state. In the event one of the following cases, the need for a balanced battery (additional) charge:
1, when the battery Fuchong operation between the team found that the battery voltage exceeds the standard deviation;
2, the exchange lost power when the time exceeds the value (such as 3 ~ 5min above) or discharge capacity exceeds the value (5% ~ 10% C10 above;
3, when Fu Chong continued operation of three to six months and check test after discharge.
Valve regulated sealed batteries, whether it is depleted of glass fiber or gel-cell battery, the electrolyte in a state of absorption or colloidal state, no free electrolyte. Therefore, the battery on the body, both high and low pressure in charge, can only charge impact on the length of time.
Tests showed that in a depth of discharge, with the same charge current, respectively, with 2.28 V, 2.30V, 2.35V, 2.40V are charging pressure charging, fully charged for the difference in time not more than three to five hours. Therefore, the valve-regulated battery charging voltage of a balanced proposal for 2.30 (+ 0.05) (- 0.02) V / months
