Li-ion charger offers redundant safety features

The GlobTek GT-93023-12012 multiple bay battery charger can charge five battery packs in unison and includes redundant safety features which, when communicating with electronics in Li-Ion batteries, prevents failure or damage of the battery pack during charging. The customer specifies a battery pack consisting of a Panasonic CGA103450A 103450-sized prismatic cells in a 3S2P configuration. The made-to-order battery pack has a built-in fuel gauge and protection circuit. The battery pack and cell temperature can be read from one of the registers inside the fuel gauge IC. 

 
The five-bay charger features a +24 Vdc ±5% input voltage, 6.25-A input, and 150-W input power. The output per bay output charging voltage is 12. 6 Vdc with an output power of 31.5-W per bay and 150 W total. The battery charger will suspend charging when the battery temperature reaches 50C, and will automatically recover when it drops below 48°C. It terminates charging and goes into a fault mode when the battery temperature reaches 0°C or 60°C.
