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.

Momentive expands its range of liquid silicone rubbers for e-mobility

Momentive Performance Materials has added two new liquid silicone rubbers (LSRs) to its materials portfolio. It says the LSRs, NL9360 and NL9330, are particularly suitable for dissipating high temperatures from sensitive components, for example in the drive system or charging management of EVs. Momentive has also announced a new low-temperature cure (LTC) LSR that cross-links […]


Cell test systems do double duty

EA Elektro-Automatik in Germany has launched a series of bidirectional DC power supplies and regenerative DC loads for testing fuel cell stacks (writes Nick Flaherty). Fuel cells are characterised by determining their electrical resistance, and the performance is usually indicated via polarisation curves by measuring the voltage and current. A durability test after a fuel […]
