The clock is ticking for electric vehicles, and charging remains a significant hurdle preventing EVs from fully replacing fuel-powered cars. However, the Nyobolt battery charges even faster than it takes to pump gas. Nyobolt, a Cambridge-based company, has developed a compact battery that could revolutionize electric vehicle recharging capabilities.
In its first live demonstration, the Nyobolt 35kWh battery pack successfully recharged from 10% to 80% in just four minutes and 37 seconds, setting a new record for the fastest charging battery. This rapid charge adds 120 miles of range to the sports car in just four minutes. As the BBC noted, an 80% charge adds up to 200 miles of range to a Tesla, but it takes 15-20 minutes to charge a Tesla to 80% using the company’s most powerful charger.
The Department of Energy estimates that powering EVs costs approximately 35-75% less per mile than gas-powered vehicles. Additionally, the UK has previously highlighted that it could reduce its total carbon emissions by almost 12% if all cars were electric.
Set to be market-ready “at a small scale” within a year (1000 packs) and currently available in the UK, the Nyobolt 35kWh battery pack could propel electric vehicles, including compact cars, into the next generation.
Furthermore, “Nyobolt’s flexible manufacturing model enables volumes of up to two million cells per year,” according to Silicon UK. Nyobolt leverages next-generation patented carbon and metal oxide anode materials, innovative low-impedance cell design, integrated power electronics, and software controls to create power-dense battery and charging systems. Their technology also addresses the degradation issues typically associated with supercharging lithium-ion batteries.
As highlighted by Motor 1, Nyobolt conducted over 4,000 full-depth of discharge fast-charge cycles, equivalent to approximately 600,000 miles of real-world use. Remarkably, the battery still charges to 80% after 4,000 cycles, defying the usual degradation over time. The Nyobolt EV prototype supercharges twice as fast as any existing battery, typically reaching 100% in six minutes in the lab.
However, cars must operate in various conditions. The fact that the battery can still charge at essentially the same rate under challenging conditions further demonstrates its value, as it will need to be tested in adverse weather to ensure full functionality.
