Electric Motors

IDTechEx currently have a number of electric vehicle related webinars available to watch on-demand. These include presentations on electric cars; electric boats and ships; thermal management; autonomous driving; and EV charging.

In the past two decades, the car market has declined twice: first due to the 2008 economic crisis, and then due to falling sales in China. Most recently, the lockdowns implemented to combat the coronavirus pandemic, causing auto-production plants to close globally and a loss of consumer spending will lead to an unprecedented 23% decline in 2020 (IDTechEx prediction).

Fuel cell electric vehicles (FCEVs) and battery electric vehicles (BEVs) are considered by the most, as two competing technologies. Although both technologies power an electric motor, they have different properties and each of them is well suited for some uses more than others.

Join Dr Peter Harrop in his latest presentation on Electric Vehicles in Construction, Agriculture & Mining, a $100 Billion Market Soon.

The drivetrain of an electric vehicle is, in theory, much simpler than a combustion vehicle. Despite this, many electric vehicle contain several different coolant fluids. Is this optimal or a remnant from legacy systems?

Thermal management of batteries for electric vehicles is a crucial issue. It is important not only for safety and thermal runaway prevention, but also for the performance and longevity of the battery.

Thermal runaway in electric vehicles (EVs) is a major concern for potential consumers, manufacturers and regulators, as thermal runaway of lithium ion batteries is the main cause of fires in EVs.

The market for electric vehicles is set to exceed $1,000bn by 2030 but potential consumers are still concerned with range, cost and safety. Whilst this draws attention initially to the battery, an equally important factor and unifying component of electric vehicles is the electric motor and its effective thermal management.

Electrics and robotics squares the circle of seeking a wider variety of depleting materials in nastier, more remote places from the seafloor to four kilometres underground, up remote mountains and later outer space. Zero-emission microgrids on-site, sensors everywhere and new information and communications technology lubricate the process.

The electric vehicle market is growing rapidly, and with it the demand for fast charging, increased energy density and improved safety. Something that all these areas have in common is heat. Charging a battery quickly generates a lot of heat, with the extra energy capacity of modern and upcoming electric vehicle batteries, extracting this heat becomes more challenging.
