查询词典 voltage gradient

The results showed that: the charging method had significant influence on deep cycling VRLA batteries;the constant-voltage charging method tended to long-term undercharge the batteries;the failure cause of constant-current charging batteries was that the active material would be soften and shed; the VRLA battery's serveice life would be improved by using pulse-charging method.

结果表明：1、充电制度对深循环VRLA电池的寿命有着重要的影响；2、恒压充电方法容易导致电池长期充电不足，从而发生硫酸盐化；3、恒流充电的电池失效原因是正极板铅膏发生软化、脱落；4、脉冲充电的方法可使深循环VRLA电池寿命提高。

Using solar cell to absorb solar energy and store into battery by DC-DC charger during daytime. When in the night, battery will be discharged to white LED by optical sensor and control circuit. Since the weather maybe cloudy or rainy, there is a spare AC power supply loop consist of transformer, bridge rectifier, filter and voltage regulator to prevent battery undercharge or circuit maintain. When the output current of battery is less than the preset value, the power source of white LED lamp will be switched over to spare AC power supply loop by the comparative and switching circuit.
