Charger for 24 Lithium Ion Batteries at a
time
A heavy duty industrial user needed to charge up to 24
Molicel battery packs, model MCR-1821C at one time. This charger has
independent charging circuits. We worked with E-One Moli Energy (Canada)
Limited to meet their charging and safety requirements. Each battery is fully
independent and its own smart controller, and status LEDs. The power supply has
universal input 85 VAC to 235 VAC 50/60 cycle. The microprocessor controlled
charger boards monitor fault conditions as well as monitor each battery
separately for state-of-charge and end-of-charge.
Options: This
product type could be extended to any number of batteries, different battery
chemistries, and different charge algorithms. It can also be rack mounted, or
repackaged for indoor use. The system monitors battery temperature to keep the
charging temperature within the limits specified by Moly Energy for their
MCR-1821C battery pack.
The microprocessor controlled charge algorithm
includes a soft start for cells that have been over-discharged in order to
preserve battery life. Moli Energy's preferred charging method for LiIon
batteries constant current / constant voltage ( CC/CV ), with the top-off
voltage accurately regulated to ensure a full charge without an overcharge. A
timer circuit is also included for safety, which cuts off the charge after a
certain time even if the termination current has not been reached.
This
battery is used for a number of types of equipment, including the Trimble
29518, Trimble 46607, Trimble 5700 GPS Receiver, Tsc1 data collector, barcode
scanners, and the HP Photosmart C912.
