Facts about Chargers . . .

Each battery chemistry requires its own charge algorithm.

A charger must be designed to safely charge batteries that are defective.

Temperature governs the speed by which a battery can be fast-charged.

Ultra-fast charging should only be applied at moderate temperatures.

The charger should limit the time the cell stays at an elevated voltages.

Cadex Battery Chargers

Intelligent Battery Adapters

UCC adapter includes a code to configure charger Services different battery types on multi-bay platform Field-upgradable by exchanging the adapter

Cold chargingLi-ion batteries can only be charged above freezing temperatures; nickel-based batteries should be trickle charged if below 5°C (41°F). The Cadex chargers provide the right service.

Hot chargingThe charger halts charge if Li-ion reaches 50°C (123°F). Nickel-based batteries resume charge after cool down and trickle charge when full.

Safety and redundancy

Advanced algorithms terminate the charge on incorrect voltages, mismatched cells and temperature extremes.

Inactive batteriesOver-discharge often render Li-ion batteries unserviceable. Boost enables a re-charge.

Calibration Discharge Maintains fuel gauge accuracy, prolongs nickel-based batteries.
