Nyobold E-Elise with 1,600 km/h Charging Speed
The vision of Nyobolt is to solve the core problems of the electric car industry that hinder the widespread adoption of electric cars worldwide. Currently, it is not possible for electric cars to achieve the refueling speed of gasoline when charging. Most batteries for electric vehicles are also large, heavy, and costly, making the costs of electric cars unaffordable for some buyers, and the vehicles often weigh over two tons. Additionally, the need for heavy EV battery packs places an enormous burden on the supply of battery raw materials.
"Nyobolt’s groundbreaking battery technology has given us the unique and inspiring opportunity to participate in the development and execution of a vehicle that will pave the way for EV technology," said David Fairbairn, Managing Director of Callum. "The combined creativity, technical skills, and relentless efforts of Nyobolt, Julian Thomson, and Callum have led to an electric vehicle that is not only technically exciting for the industry but also beautiful to look at."
To suitably showcase the new battery technology
The E-Elise features a carbon fiber body, sits on 19-inch wheels, and is 100 mm wider and 150 mm longer than the original Elise. The “rearview” cameras are discreetly integrated, and the Type-2 charging port is inconspicuously located in the B-pillar. Aleck Jones, creative director at Callum, explains the design of the electric Elise:
“The goal was to evolve the design and bring it up to date without losing the iconic sports car character that was so well received with the Elise.”
The Nyobolt EV is intended to weigh about a ton, uses a 35-kWh battery and can be fully charged in under 6 minutes with existing charging infrastructure, providing a range of up to 250 km. This corresponds to a charging speed equivalent to over 1,600 km/h, which means the E-Elise charges more than twice as fast as the fastest electric cars available at charging stations today.
“Normally, you encounter feasibility issues with initial sketches, and a design loses its impact when transitioning from concept to reality, but thanks to the close collaboration between Callum's design and engineering teams, we were able to bring our early images and unique vision into the real world,” Jones further explains. “Nyobolt's technology allows this car to meet all the criteria that made the original Elise such a coveted driver’s car with a cult following, but it’s electric. These two things usually don’t go hand in hand because the weight and battery pack size are limited.”
Small Battery, Small Range, Fast Charging
Although the new Nyobolt electric car is equipped with a fairly small 35 kWh battery, the EV is said to have a range of 250 km. According to the engineers, they have tested the charging and discharging cycles over 2,000 times without significant losses.
Nyobolt introduces a new battery technology that is smaller and lighter and can be fully charged in just six minutes, with a range of up to 250 km. This breakthrough is expected to lead to a nimbler, more efficient electric car with lower acquisition costs, lower operating costs, and reduced consumption of scarce raw materials. Additionally, the technology is expected to be scalable, meaning luxury EVs, trucks, or buses can also be equipped with large batteries and charged within minutes once the necessary 1 MW chargers become available.
“Solving the challenges faced by electric vehicle designers was key to the development of our groundbreaking fast-charging batteries. Until now, it was not possible to build a lightweight, fast-charging vehicle without compromising its lifespan, so one had to rely on expensive and large battery packs in the vehicle,” says Sai Shivareddy, CEO of Nyobolt. "With our unique technology, we have managed to charge a car in six minutes and develop smaller batteries that deliver more power and can be charged in less time.”
What does this mean?
Elise and electric - it is not the first time that a Lotus has been used as a demonstration vehicle for electric cars. Elon Musk famously brought Tesla Motors to market with such a vehicle. However, Musk later said that despite its low weight, it was a poor choice for the Roadster because the battery equipment could not be easily integrated into the car. However, the engineers at Nyobolt have transplanted a relatively small battery with ultra-fast charging into the Elise replica sports car. Nyobolt's battery technology is expected to go into production in early 2024.
