目前快速充电技术已在国内广泛推广应用,使蓄电池充电时间大为缩短。一般快速充电循环过程是充电、停止、放电、停止。充电电流为电瓶容量的一倍,放电电流为电瓶容量的几倍至几十倍,放电时间在一毫秒以内。而电瓶车等大、中功率的电瓶,要求充电电流大(数百安培),放电电流更大(上千安培)。这样,对放电回路元件的可靠性要求就高,不易达到。 为了解决这个问题,根据兄弟单位的经验,结合我厂的具体情况,我们试制一套快速充电设备,适于30～60伏电瓶车和电瓶铲
The current rapid charging technology has been widely used in the country, so that battery charging time is greatly reduced. Generally fast charging cycle is charging, stopping, discharging, stopping. The charging current is double the capacity of the battery, the discharging current is several times to several times of the capacity of the battery, and the discharging time is within one millisecond. The battery car and other large, medium-power battery, requiring large charge current (hundreds of ampere), discharge current greater (thousands of amperes). In this way, the reliability requirements of the discharge circuit components are high, not easy to achieve. In order to solve this problem, according to the experience of brothers unit, combined with the specific circumstances of our plant, we trial a set of fast charging equipment, suitable for 30 ~ 60 volt battery car and battery shovel
