Keysight Technologies announced the launch of a suite of test and measurement solutions for the battery, HEV/EV and HEMS markets. Those solutions enable developpement of cell and battery technologies, electrical powertrain components, and sub-systems used in hybrid and electric vehicles, and in associated energy storage units.
The electric vehicle market, ranging from mild hybrids to battery electric vehicles and HEMS, is fast growing. According to Keysight, based on these dynamics, many cell and battery manufacturers are facing challenges to deal with the exponential demand for costly, high-power/high-voltage cells in the 300 V range. This is compared to the traditional, more cost-efficient 12 V cells.
EV1003A Power Converter Test Solution – designed to address the efficiency, safety, regulatory and environmental challenges associated with the HEV/EV and HEMS markets. This commercial off-the-shelf regenerative power system with integrated safety features protects operators and the devices under test.
RP7900 Series Regenerative Power System – offers battery emulation capabilities, such as 2-quadrant (source/sink) operation and programmable output resistance. In addition, the power system provides the added benefit of safely and cleanly regenerating greater than 85 percent of power back into the grid—which increases efficiency based on reduced energy consumption and cooling requirements.
BT2191A Self-Discharge Measurement (SDM) System – for cell designers, the BT2191A SDM system offers a new way to measure Li-Ion cells’ self-discharge currents, within a reduced amount of time and with a settling time as low as one to two hours. This new patented technique allows engineers to reduce the design cycle-time and helps to optimize self-discharge performance and characteristics of battery cells.
BT2152A Self-Discharge Analyzer (SDA) – for Li-Ion cell manufacturers, the BT2152A SDA offers a new type of analyzer that measures in parallel self-discharge currents on a large number of cells, providing a reduction in the time required to discern good versus bad cell self-discharge performance.
