Energizing the Future with REGATRON's New Battery Tester Series

Read why REGATRON's G5.BT series is best suited for battery module/pack-testing in your laboratory or test bench environment.

REGATRON's regenerative bidirectional G5.BT Battery Test System is safe, reliable, and modular. It features an exceptional current accuracy of <0.02% FS, an additional high-resolution current measurement range, and a fast current rise time in the 100 µs range.

Working with high-power batteries is very demanding. Voltages, currents and temperatures must be monitored and kept within a safe range. In addition, connecting a battery to a load or battery tester also requires appropriate attention to polarity and voltage levels. Today's batteries are no longer simple battery cell stacks, but complex modules with superposed power electronics that require highly accurate data acquisition and fast response times.

The REGATRON Solution

REGATRON's G5.BT Battery Tester Series is designed specifically for testing energy storage devices and fully meets the above mentioned requirements. To increase personnel safety and equipment protection, the G5.BT series includes the field-proven RPP feature against the two main risk factors that are given when a battery is physically connected to the battery tester. First, RPP reliably prevents all serious damage caused by accidental reverse polarity between battery and battery tester. Second, RPP provides overcurrent protection/soft start in case of unmatched voltages between the battery and the battery test system. Another valuable function of the integrated RPP feature is the prevention of deep battery discharge at 'Voltage Off' state.

The excellent current and voltage accuracy, the fast current rise time, and the powerful integrated CAN multi-protocol interface enable tests with a high temporal and electrical resolution. The specialized application software BatControl allows the user to set many test parameter values and even to define complex test procedures. Therefore, the versatile G5.BT series is best suited for testing all types of batteries and energy storage systems.

Modular and Easy Scalable Systems

The output of an individual battery module/pack-testing system is in the range from 0...18 kW to 0...2000+ kW, up to 1500 VDC. Higher voltages are available on request. The advantageous modularity of REGATRON power supply solutions allows the system to be easily adapted to ever changing test requirements. Not only is it possible to reconfigure between parallel, series, and mixed operation, but also to expand the system with additional power supply units or to split it into smaller units. Therefore, the purchase of a REGATRON battery tester is a solid investment for the future.
