NiMH Battery Pack Charger

N100-XXG is a main member of digital-chargers from Green Digital Power-tech Co., Ltd. It represents today's new technology for 24V(20s) ~ 36V(30s) NiMH/NiCd battery pack charging. N100-XXG programmed 3 auto Stages ( IP-Im-It) charging process, It is designed for 20s(24V) ~ 30s(36V) 4~25Ah NiMH/NiCd battery pack. Stage "IP" is a pre-charge function for Deep discharged battery pack, this is helpful for battery's cycle life. When the Battery recovered by pre-charge small current, stage "Im" will give bulk current Charging. This is the main charge stage, when the battery nearly charged full, -DV phenomenon will be detected by the MCU in charger (-DV value is 3~6mV/per cell about). Then the battery will leave bulk stage and cut-off Output or enter a defined trickle pulse charge stage "It" to maintain battery.

Further, N100can display the charging process, indicate the battery Capacity from 25% to 100% timely. This is helpful for user.

For more safety, N100 will inter protection mode when the battery polarity Reversed our the output connectors shorted.
