Matrix aimed at seal and EMI issues

The Electrically and Thermally Conductive and Electromagnetic Interference Shielding Materials (ETEMI) project aims to enhance conventional elastomers, liquid silicon rubber and thermoplastics to address sealing and EMI issues at the same time in EVs. This is driving the development of a new class of electrically conductive sealing materials.

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

Nanotech alloy ups HV power

The LISA (Lithium Sulphur for Safe Road Electrification) European project is developing a 20 Ah solid-state lithium-sulphur pouch cell with high gravimetric energy of 450 Wh/kg and volumetric energy density of 700 Wh/litre that will be stable for at least 1000 cycles. The first step is a proof-of-concept 21700 cylindrical cell with a capacity of 3 Ah.

Towards a 1000-mile range

One thousand miles is a nice, round number, and as a range for a battery EV it is a marketing department’s dream. However, there is real value in such a long range if it can be achieved by a production roadcar in representative trim rather than niche vehicles and technology demonstrators.
