Equipmake’s ZED system for buses set to enter service

Developing heavy-duty powertrains for integrating into electric passenger buses is fundamentally different from other EV applications, owing to their unique drive cycles and weight-carrying considerations, and their dramatically different HVAC requirements (writes Rory Jackson). Unlike other EVs, an electric bus can expend as much energy on heating and cooling its cabin interior as it does […]

Tackling EV tyre particulates

The most supportable claim by EVs to environmental friendliness is that they lead to cleaner air in towns and cities because they emit no combustion products (writes Peter Donaldson). The fly in that ointment is particles from tyre wear, of which EVs tend to generate more because they are heavier than comparable IC-engined vehicles and […]

BorgWarner’s plans for high-voltage commercial vehicle power systems

Total cost of ownership, long service life and packaging efficiency that frees mass and volume for cargo and passengers are essential requirements for all commercial vehicles (CVs) – and meeting all those needs is a challenge as the sector transitions to electric power, according to Harry Husted, BorgWarner’s vice-president and CTO (writes Peter Donaldson). Speaking […]

Flextem’s PTC heating films for batteries

Heating is as important as cooling in the thermal management of battery packs, since lithium-ion batteries need to be held within the temperature range specified by the cell manufacturer if they are to operate safely and efficiently, and achieve their maximum service life (writes Peter Donaldson). Efficient, self-regulating positive temperature coefficient (PTC) heaters constitute an […]

BorgWarner to start production of Akasol CYC battery modules

Cylindrical cells and central liquid cooling are key architectural characteristics of the new “ultra-high-energy” Akasystem AKM CYC module technology from BorgWarner, which acquired its developer Akasol in February (writes Peter Donaldson). The system is a scalable set of battery modules designed to be built up into packs for heavy vehicles including buses and trucks, along […]

DAFO Vehicle battery fire protection system

In a thermal runaway, a lithium-ion battery typically releases oxygen from the cathode and volatile hydrocarbons from the electrolyte, generating both oxidiser and fuel to sustain a fire from purely internal sources (writes Peter Donaldson). Reliable detection and early intervention are therefore critical for preventing the worst consequences of battery thermal incidents – fire and […]

Safe AI for batteries

While we are growing used to artificially intelligent software in smartphones, for example, if  AI and machine learning are to benefit EV applications such as controlling batteries, inverters and motors, the software must meet all the safety, security and quality standards that apply to serial production vehicles in the automotive industry. This is the mission […]
