The Cadex Universal Conditioning Chargers (UCC) offer refinements usually not found on competitive chargers. The rugged design stands up to the critical demands of industrial users. Intelligent adapters allow simultaneous service of nickel-cadmium, nickel-metal-hydride and lithium-ion batteries on the same platform. A conditioning button conditions and calibrates batteries on demand, and a reverse-pulse charging prolongs battery life.
This compact single-bay battery charger assures freshly charged batteries in the office and on travel. The UCC 1 comes with a 60-watt universal AC power supply for all global voltages.
Part Number: 11-300-0120
Cadex UCC 2
The two-bay charger is designed for desktop, wall mount or vehicle use. The AC version comes with a 60-watt universal power supply. When used in a vehicle, a DC-DC converter regulates the 12VDC input voltage to assure proper charging.
Part Number: 11-300-0220
Cadex UCC 6
The six-bay charger is suited for desktop or wall mount and features an internal 100-watt universal power supply with detachable cord.
Part Number: 11-300-0610
Individual charger modules
Each bay includes a UCC module that charges lithium and nickel-based batteries from 3.6V to 15V at 15W and 25W. The charge currents range from 50mA to 3A at an input from 12VDC to 36VDC. This enables charging a 15V battery in a 12V vehicle.
INTELLIGENT BATTERY ADAPTERS
The adapters contain a battery code that configures the charger to the correct battery parameter. This allows maximum flexibility in charger configuration. Nickel-cadmium, nickel-metal-hydride and lithium-ion batteries can be serviced side-by-side.
Redundant algorithms provide safety even with a known defective battery. Incorrect battery voltage, mismatched cell and temperature extremes halt the charge by alerting the user with a red fail light. This feature protects the battery and charger.
When charging at cold temperatures, the UCC charger applies a gentle trickle charge to warm up the battery, then switches to fast-charge at operating temperature. A charge time-out prevents a prolonged charge if the temperature does not rise.
Should the temperature of a nickel-based battery reach the upper threshold level, the UCC allows the pack to cool before resuming at half the previous charge current. If the temperature threshold is reached again, the current is lowered further to reduce heat related battery damage.
Safety and redundancy are key in charger design. Advanced algorithms terminate the charge on incorrect voltages, mismatched cells and temperature extremes. RUN, READY and FAIL signals provide status.
Intelligent batteries need a periodic full discharge for calibration, and nickel-based batteries should be exercised every three months to prevent memory. The discharge function of the Butterfly provides these services on command.
Reactivating lithium-ion batteries
The UCC wakes up seemingly dead lithium-ion packs by applying charge pulses to reactivate the safety circuit. A full charge commences when the battery reaches a safe charging voltage.
Full-charge detection of nickel-based batteries occurs on negative voltage slope, rate of temperature increase and/or a rapid temperature change (dT/dt). Lithium-ion terminates the charge on voltage plateau and current saturation.
A condition button allows discharge on demand to reverse memory and regain lost performance. Nickel-cadmium batteries require monthly service; nickel-metal-hydride should be discharged once every three months. The condition cycle also calibrates batteries with fuel gauge.
The UCC charger intersperses discharge pulses between charge pulses to improve charge acceptance on nickel-based batteries. This method promotes the recombination of oxygen and hydrogen gases generated during charge. This results in faster charge times, better battery performance, reduced memory and longer service life.
