Battery Pack and Charger System Offered for Mobile Handheld Equipment
GlobTek’s five-bay lithium-ion battery chargers and cradles meet IEC 60950 (ITE), UL 1310 (Class 2), IEC 60601-1 (Medical), and International EMC standards. The charger charges battery in three phases: conditioning, constant current, and constant voltage. Charge is terminated based on minimum current level and a programmable charge timer provides a safety backup for charge termination. The design also incorporates an MCU for battery identification, charge status display, and battery temperature monitoring using HDQ communication protocol from BQ27000 battery fuel gauge IC embedded inside the battery pack. Each bay can provide bulk charge current up to 750 mA at 4.2 V maximum voltage for off-the-shelf GlobTek 2GL-523450-G or customer designed battery packs. Modified, custom, and higher wattage designs adaptable to customer battery packs or alternate specs are also available. GlobTek now offers a five-year warranty.
