Halving the time it takes to roll out battery packs

Ionetic has developed a system of software, hardware and manufacturing technologies to simplify the development of battery packs, writes Nick Flaherty. OEMs needing 100 to 10,000 battery packs a year are faced with a difficult choice: expensive, time-consuming, highly bespoke battery packs or low-performance, off-the-shelf systems.

E-bikes gain BMS based on 100 V Gan devices

Innoscience Technology has launched a battery management system (BMS) based on 100 V gallium nitride (GaN) devices for electric three-wheelers and e-bikes, writes Nick Flaherty. The VGaN devices are connected by a common drain for bidirectional switching of battery charging and discharging, reducing on-resistance to 3.2 mΩ.

Ilika tests 10 Ah cells to hit Goliath D6 milestone

Ilika has reached its D6 milestone by testing 10 Ah cells in its Goliath solid-state batteries for electric vehicles. The modelling of a Goliath-based battery pack for EVs is under way by UK company Balance Batteries. Early results show the weight of the battery pack can be reduced by up to 100 kg on the basis of Goliath’s benefits, compared to a current SUV lithium-ion model of the same energy.

Cell ageing characteristics

Modelling battery cells at end of life is becoming more popular for key reasons, as Nick Flaherty reports. Accurate prediction of battery lifespan is crucial for e-mobility and involves a variety of test approaches, from thermal measurements to transmission electron microscopes. Assessing how a cell delivers power when required and how it is charged provides insights into its lifetime.
