heating
The operation of HVAC systems in PEVs or any fully electric vehicle poses many of the same problems that running other systems face, but HVAC use poses some unique challenges, too. In climates where electric cars are or will be a major part of the transportation load from now on, consumers demand efficient and powerful heating and cooling in their vehicles. To help system improvements now underway in fully electric vehicles, engineers had to move away from the vehicle’s ability to use the large amount of excess heat produced by internal combustion engines. Regulating the temperature in any battery vehicle is a delicate venture since the power source degrades by calculable amounts under regular use, but by irregular amounts under the most stressful conditions.

As the world moves towards Zero Emissions and full electrification, certain materials become more than mere commodities as their strategic importance increases: Studies conducted by the European Commission's Joint Research Centre concluded that several low-carbon energy technologies could be at risk because of potential bottlenecks in the supply chains of certain metals. Among these, critical rare earth metals are used in NdFeB permanent magnets and are essential for producing light, compact and high-efficiency traction motors. These ‘supermagnets’ contain neodymium (Nd), praseodymium (Pr) and dysprosium (Dy) rare earths in their composition.

Cyber security
It’s not just the increasing use of smart devices driving the development of the next generation of wireless technology; 5G is also needed to support a wide range of Machine to Machine (M2M) and Internet of Things (IoT) applications. Amongst these are services and applications that will support connected vehicles. Industry interest in V2V (vehicle to vehicle) and V2I (vehicle to infrastructure) connectivity is largely being driven by the key role it will play in enabling driverless vehicles. This increased connectivity will see the amount of data being created and subsequently sent to the cloud increasing exponentially as new devices, including cars, find innovative ways to leverage the IoT.

thermal management
Quickly removing heat and mitigating the damage from excessive heat has been a primary concern for motor vehicle designers since the internal combustion engine was first used. As engines got more powerful and were enclosed in compartments, reducing heat became more critical. Of course, as vehicles became more complex and accessories were added, these loads were added to engines and battery/electrical systems needed to be heavier and more complex, too.

The higher the level of automation for a car, the more “intelligent” the vehicle needs to become. Evolved from the study of pattern recognition and computational learning theory in artificial intelligence, machine learning explores the study and construction of algorithms that can learn from and make predictions on data – such algorithms overcome following strictly static program instructions by making data-driven predictions or decisions, through building a model from sample inputs.

In September 2015, the Volkswagen ‘DieselGate’ scandal broke and rocked the automotive world and changed the landscape of engine emissions testing for good. The German auto giant was found to have developed a ‘defeat device’ that when sensing the vehicle was under test conditions, switched its performance accordingly to suppress emissions of pollutants, notably nitrogen oxide (NOx), which under real-life driving conditions were in fact signficantly above legal limits. In effect, it allowed VW to get away with NOx emissions that were up to 40 times the legal US limit.

The greater electrification of vehicles is a trend that continues at pace, and one that has led to a variety of innovations in recent years. Driven by ever more stringent emission targets, the move towards hybrid and electric cars has seen rapid development in electrical architecture in a number of sectors.

With regions across the globe experiencing drastic and often catastrophic climate related events, the earth appears to be firmly in the grips of global warming. To save the planet world leaders from 195 countries adopted the first-ever universal, legally binding global climate pact in December 2015. The Paris Accord, which came into force on 4 November 2016, sets out a comprehensive action plan to limit global warming to below 2°C, come 2050.

5G
According to many experts in the field of generational wireless, the coming fifth generation (5G) major upgrade will create the actual Internet of Things, a concept of connected machinery that heretofore has been a scattered collection rather than a cohesive system. Cars (and larger vehicles) are quickly becoming stand-alone computer servers, but the next step makes them capable of becoming communication centers, entertainment complexes and full-service electronic outlets.
