Electric vehicles are a key part of the global drive to reduce carbon emissions, and the switch from fuel-powered engines is changing how our cars are designed, built and experienced. From battery breakthroughs to smarter software and charging networks, discover how EVs are driving automotive engineering developments.
- Revolutionising battery technology
Battery technology is a vital part of EV engineering. As the main power source for an EV rather than just the spark to start the engine and electronics, battery performance directly impacts the range, cost, and lifespan of EVs, which are all major concerns for drivers considering going green.
In the initial years after their release, buyers were wary of investing in EVs due to practical issues. To make battery-powered vehicles more appealing, car companies are racing to develop batteries capable of faster charging, longer ranges, and reduced overheating. Significant advancements have already been made, complemented by an overhaul of road infrastructure to ensure sufficient charging points in key places.
- Innovating electric powertrains
Unlike traditional internal combustion engines, EVs rely on electric powertrains. These consist of the battery, power electronics, an energy conversion system (electric motor) and a transmitter. The smooth acceleration you feel when driving an EV comes from an electric motor delivering instant torque.
Engineers are working tirelessly to make these motors more efficient, using advanced magnet designs and lightweight materials. Reducing the weight and optimising the aerodynamics will help extend the EV range, so motors and gearboxes are being integrated into compact uses to free up space and minimise drag.
Multi-motor setups are also transforming how vehicles perform. You might have seen EVs boasting all-wheel drive and unparalleled stability. These features rely on electric powertrains, which can distribute power to each wheel independently. This innovation doesn’t just enhance your driving experience—it also improves safety on slippery or uneven roads.
- Inspiring auto software systems
Automotive companies are also integrating smart technology in their EV designs, so these vehicles feel more like computers on wheels than cars! At a basic level, this includes features like lane-keeping assistance, adaptive cruise control, real-time route recommendations and internal battery management that can be linked to your smartphone via an app. These upgrades will revolutionise how you drive and car maintenance.
More complex machine learning systems are also included in the latest EV designs to support maintenance and prolong the model lifespan, minimising waste. For example, predictive smart auto repair software identifies issues instantly and flags their urgency, giving valuable diagnostic system insights and estimating repair time. Knowing about problems as soon as they occur allows you to fix them before they become too costly, reducing the stress and cost of faults.
- Driving infrastructure developments
EVs moving into the mainstream has forced the hands of the government, businesses and homeowners, demanding developments in road infrastructure nationwide. The number of charging stations on main routes was the initial priority, and now grants are available for landlords and flat residents to help support chargepoint installation in private properties.
Recently the focus has shifted to making these chargepoints faster and more reliable. Ultra-fast chargers, capable of delivering 200 miles of range in under 20 minutes, are becoming common. This development is backed by elevated thermal management systems more resistant to overheating. You’ll also notice chargers integrated with smart grids and renewable energy sources like solar panels, making charging more sustainable.
