The P45B has a 10C pulse discharge capability and a 3C charge capability but can still provide a 242 Wh/kg nominal specific energy. Its low DC internal resistance is measured by About:Energy at 13.8 mΩ (7.86 mΩ for 0.2 seconds) bodes well for high C-rate use cases, particularly where the thermal management system is constrained.

Cotes cuts carbon footprint of running dry rooms

Drying rooms are critical to lithium-ion battery manufacture to ensure that the electrodes are prevented from absorbing moisture, which can lead to a reduction in lifespan and even catastrophic failure (writes Peter Donaldson). Running these dry rooms typically takes a lot of energy, mostly to provide hot air. However, Danish company Cotes has developed a much more efficient way it calls Exergic Technology to do this that significantly reduces the battery’s overall carbon footprint. Understanding humidity is key to getting rid of unwanted moisture from air, and warm air holds more water than cold air. Absolute humidity is the amount of water vapour in a given mass of air, and is typically expressed in grams per kilo. Relative humidity, meanwhile, is the amount of water in the air expressed as a percentage of the maximum it can hold at a given temperature. When that percentage exceeds 100, the water begins to condense out.

Operating EVs in extreme temperatures is a demanding exercise, as lithium-ion batteries generally work best between 15 and 35 C, so a four-week trial conducted throughout February 2021 above the Arctic Circle in Sweden was a severe test of a truck and its charging infrastructure (writes Peter Donaldson). In the test, the battery-powered truck carried loads of 14 t of iron ore sludge over a 280 km round trip in temperatures down to -32 C, says Adam Holmer of power-as-a-service provider Vattenfall. The trial was a cooperative effort between Vattenfall, Volvo Trucks and dealer Wist Last och Buss, charger manufacturer ABB and mining company Kaunis Iron.

Ground vibration testing of NASA’s X-57 Maxwell electric aircraft

Electric propulsion is spawning aircraft with diverse and novel configurations. The multiple motors, rotors, propellers and fans associated with distributed electric propulsion are shaping many complex and unusual forms in the quest to enhance lift and thrust, and to reduce drag through close aerodynamic coupling with airframes. One of the most important processes in their development is ensuring that they don’t suffer from damaging vibration. To that end, NASA has used equipment from Hottinger Bruel & Kjær (HBK) to collect and process accelerometer data in ground vibration testing (GVT) for its X-57 Maxwell aircraft.
