Validating BMS performance

Battery management systems are becoming increasingly safety-critical, as they are responsible for balancing battery cells operating at several hundred volts and maintaining temperatures within narrow working ranges to prevent thermal runaway (writes Peter Donaldson). Gauging the performance of a BMS during r&d, validation, verification and production is therefore of vital and growing importance. Bloomy Controls’ new Flex BMS Validation System is focused on the validation part, particularly in situations where the developer needs to test more than one BMS design.

StoreDot announces eXtreme approach to charging

StoreDot is developing new a lithium-ion battery technology it calls eXtreme Fast Charging (XFC) that will enable an EV to charge in 5-10 minutes (writes Peter Donaldson). At the heart of it is a silicon-dominated anode that can accept lithium ions much faster than a graphite anode (thanks to silicon’s lower resistance) but controls

Battery vent protects against rapid rises in pressure

As the battery pack is the single heaviest and costliest component of an EV drivetrain, weight reductions in the pack pay dividends in terms of range as well as performance and handling. One of the ways battery manufacturers are looking to reduce weight is to produce packs with thinner walls, which means that they must operate at lower internal pressures and with those pressures carefully controlled.

SAF-Holland develops e-axles for refrigerated trucks

Keeping a refrigerated truck powered at all times can be challenging with an all-electric powertrain (writes Rory Jackson). Finding enough battery ‘real estate’ beneath an 18-wheeler’s chassis for long-haul transport of freight is one thing; add a power-hungry refrigeration trailer and drivers could find their battery energy levels running low with irritating frequency. SAF-Holland’s TRAKr […]
