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...

Bipolar nickel-hydrogen battery for 2021 Toyota Aqua

Toyota’s new Acqua compact HEV comes with a bipolar nickel-hydrogen battery, a world first for a road vehicle according to the Japanese automotive giant (writes Peter Donaldson). Conventional non-bipolar nickel-hydrogen batteries have a much lower energy density than lithium-ion versions but much longer service lives. Compared with the nickel-hydrogen battery in the previous-generation Aqua, says […]
