Battery Safety

The EV battery industry offers a variety of ways to minimise the hazards they can pose, as Peter Donaldson explains. Proximity to large amounts of energy has always presented hazards, but people have mostly learned to live with them and enjoy its benefits....

Battery cooling

As liquid-based cooling for EV batteries becomes the technology of choice, Peter Donaldson explains the system options now available. Although there are other options for cooling EV batteries than using a liquid, it is rapidly taking over from forced-air cooling, as energy and power densities increase. It is emerging as the dominant technology...

Condition monitoring

Peter Donaldson examines the factors involved in keeping tabs on the health and performance of key EV components. While an EV’s most costly component is its battery, there are also many other subsystems – inverters, generators and so on – whose condition is critical to safety and efficiency. Machinery health and usage monitoring is well-established...
