Springs in the Evolution of Electric Cars
In the pursuit of a more sustainable future, over the past few years, the automotive industry has witnessed a remarkable transformation with the rise of electric vehicles. Advancements in battery technology, charging infrastructure, and government policies supporting the adoption of electric cars are only a few of the many changes the sector has seen. However, we must not forget that if these significant shifts were made possible, it was thanks to an essential component: springs. As indispensable elements in the design and functionality of electric vehicles, springs ensure that various systems are efficient, contributing to electric cars’ overall success.
In this blog, we will discuss the evolution of electric vehicles, the key milestones in their development, and the principal factors driving their popularity. We will also see how at European Springs, as a leading UK spring manufacturer, we have adapted to support the automotive revolution.
The Evolution of Electric Vehicles
Although it may seem recent, the story of electric vehicles traces its origins back to the beginning of the 19th century. Over time, this form of clean energy transportation has seen tremendous progress and has now established itself as a feasible and preferred alternative to cars powered by internal combustion engines.
In their early phases, electric cars were limited in terms of range and performance due to inadequate battery technology. However, the game-changing shift happened in the automotive industry with the invention of rechargeable lithium-ion batteries, which gave electric vehicles the ability to travel longer distances without the need for constant recharging. This technological leap allowed them to rival their petrol-fuelled counterparts, marking a significant milestone in their evolution.
Then, another major change happened; in 2008, the Tesla Roadster was unveiled, and it was a game-changer. This stylish and high-performing electric car broke the paradigm of electric vehicles being aesthetically unappealing or having poor performance, not only revolutionising public perception but also prompting other manufacturers to invest heavily in electric vehicle technology. Since then, the field of electric vehicles has seen continuous advancements. The creation of more efficient electric motors, the progressive refinement of battery technology, and the widespread establishment of charging infrastructures have all played their part in augmenting their growth.
Electric Cars and Their Popularity: The Driving Factors
Several factors have contributed to the increasing popularity of electric cars in recent years, and we mentioned a few technological ones. However, these driving factors extend far beyond technology and cover consumer interest, government policies, and industry buy-in.
Starting from a technological standpoint, innovations in battery technology have significantly increased the energy density of lithium-ion batteries, allowing for longer driving ranges and faster charging times. As battery costs continue to decline, electric vehicles have become more affordable, narrowing the price gap with traditional internal combustion engine vehicles.
At the same time, governments worldwide started implementing policies and incentives to encourage the adoption of electric vehicles, including tax credits, rebates, and infrastructure investments. On top of this, the growing awareness of environmental issues and the need to reduce greenhouse gas emissions and improve air quality has also fuelled the demand for sustainable transportation solutions, making electric vehicles an attractive option for eco-conscious consumers. In some cases, governments have even mandated the phasing out of fossil-fuel cars in the next couple of decades to accelerate the transition to electric vehicles.
Buy-in from the auto industry is another relevant factor, and major automakers (the most famous being Tesla) are increasingly investing in the research, development, and production of electric vehicles. Finally, the ongoing construction of a robust charging infrastructure, which is fundamental, is speeding up the use of electric vehicles, as this reduces concerns about range limitations and simplifies the charging process.
The Essential Role of Springs in Electric Vehicles
While much attention is given to the high-tech components of electric vehicles, the role of springs is often underestimated. As electric vehicle technology evolves, so do their spring systems, which are essential in several key aspects. For example, they ensure smooth operation and overall safety, providing enhanced functionality largely through the vehicle’s suspension system. As the entire weight of the car rests on the springs, their compliance helps absorb the impact of road irregularities and shocks on the passenger compartment. Some electric vehicles are even adopting air spring suspensions, which are becoming very popular in premium vehicle segments.
But this is only one aspect. Let’s take a closer look at where and how springs come into play.
Suspension Systems: as we said, here, springs contribute to a comfortable ride by absorbing shocks and vibrations. In electric vehicles, where the weight distribution may differ from traditional cars due to the placement of batteries, the suspension system relies on specially designed suspension springs to maintain optimal balance and ride quality.
Battery Packs: the weight of electric vehicle batteries requires robust suspension systems to support and stabilise the entire vehicle. Specially custom-designed springs help distribute the load evenly, ensuring a safe and efficient ride.
Charging Connectors: springs are utilised in the design of charging connectors, ensuring a secure and reliable connection between the charging station and the electric vehicle. This is fundamental for the seamless transfer of electrical power during the charging process.
Braking Systems: in the braking systems of electric vehicles, springs are critical in assisting in the smooth function of brake pedals and contributing to overall safety. Regenerative braking systems, common in electric vehicles, rely on springs to facilitate the transition between regenerative and traditional braking.
Other Hardware: springs, as fundamental components working in the background, find applications in various other systems and mechanisms of electric vehicles, from door handles and latches to seating systems. Their versatility and reliability enhance the overall performance and longevity of these electric vehicles.
Whether for suspension, vibration-damping, or even energy generation, we can easily understand how springs serve a fundamental role in the mechanical operation and passenger experience of electric vehicles.
