Valence Technology is now shipping four recently-introduced models of its Saphion U-Charge Power System large-format lithium-ion batteries as well as a new Battery Management System (U-BMS). (Earlier post.) The U-Charge XP Power Systems are capable of peak power rates of 500 to 1700 continuous watts, depending on the model.
Three of the four new models are conveniently packaged in standard lead-acid sizes and operate at standard lead-acid voltage ranges. The UEV model is a unique size that has a taller profile for tighter footprint compartments and an 18-volt nominal rating.
Each model includes integrated battery monitoring electronics and a communications port to access battery data. As many as 30 of these battery systems can be connected in series for very high voltage applications such as pure electric vehicles, hybrid electric vehicles, marine and power back-up applications.
The U-BMS can be used with 12-volt to 450-volt applications to provide battery-to-battery balancing, battery system monitoring, direct control of external disconnects, and remote battery system control. The U-BMS can communicate with system controllers via either CAN Bus or RS-485 Protocol.
The U-Charge XP models began shipping in May 2006, within the delivery window announced in January. Also announced in January, the U-Charge RT Series, designed for applications such as electric wheelchairs, is on track to ship all models within the next month.
