Charger Safely Accomodates Lithium-Based Batteries

Nexergy’s LC Series of battery chargers is designed specifically for Li-ion and Li-polymer batteries. The chargers feature the ability to be tailored to the unique charging requirements of each application.

The LC charger series shares a common platform with Nexergy’s NC Series chargers for nickel-based battery chemistries. The LC Series is available in a 12-W or 24-W version, with output current of up to 3 A. Its higher voltage allows the chargers to accommodate batteries with up to six Li-ion or Li-polymer cells in series.

The LC chargers are customized with firmware, aligning charge current and voltage to match the specific charging needs of the battery pack. The chargers can also detect the presence of a battery even when the protection circuit has shut off the battery’s output.

Charge will be limited or disabled if conditions are not appropriate for the cell to receive full charge. Also, charging is automatically stopped if the temperature exceeds a pre-programmed threshold. Furthermore, charge time can be limited to prevent it from being applied to damaged cells that cannot reach normal termination.
