UK-based MIRA, a global development partner to the automotive and defense sectors, has installed a comprehensive battery test and development suite at its dedicated component development center near London. The new equipment will support the rapid development of the latest Electric Vehicle (EV) and Hybrid Electric Vehicle (HEV) powertrains.
To meet increasing market expectations for longevity, high storage capacity and dynamic power flows, rig testing provides the most expedient and cost effective route to performance assurance, MIRA says. Its solutions allow the parallel development of primary traction battery systems, which run alongside the overall vehicle development program to provide the broadest development window.
High voltage (500V) traction batteries can be exercised directly using a 400 Amp, 200 kW unit. When teamed with a separate battery simulator, MIRA can also test ancillary EV components. This capability provides a crucial opportunity to develop EV components prior to prototype battery packs coming on stream. Multiple battery cells/modules can be exercised simultaneously on a secondary system operating up to 72V.
The latest high voltage, high power exercisers are configured to be coupled with MIRA’s array of environmental test equipment. These simulate real world meteorological conditions and draw on representative road load data to add an extra layer of complexity and realism to a battery development program.
MIRA’s equipment can be tuned to support proprietary and third party peripheral devices on industry standard protocols such as: RS485, CAN, I²C, SMBus, and Ethernet. MIRA’s engineers can automatically develop test programs from existing drive cycle data, which is useful for executing proprietary development tests and industry standards such as: FUDS, SFUDS, DST, and ECE-15L.
