Charging Regulation for Battery Packs
The "ZPBCM" is a small family of products for intelligent management of battery packs with a nominal voltage of 7.2 to 14.8 V (typ. 2-4 cells LiO/LiFePO4¹ or 6-12 Zellen NiMH). ZPBCM is connected as a T-piece among the power supply, battery and the device. It either works completely autonomous ("ZPBCMA") or communicates with the device ("ZPBCMB").
This ZPBCM-systems have the following properties²:
- Control by integrated µC
- High efficiency when loading and routing
- 2 variants
