Founded in 2019 by University of Cambridge battery scientists Professor Clare Grey CBE and Dr Sai Shivareddy, Nyobolt collaborated with CALLUM, a British design and engineering firm, to test the fast-charging EV battery in a high-performance environment.<\/p>\n
To do this, CALLUM developed a concept Nyobolt EV to validate the battery’s performance, revealing it can charge from 10 to 80% in a staggering four minutes and 37 seconds.<\/p>\n
The fast-charging EV battery could revolutionise the uptake of EVs, as charging times and range anxiety<\/a> are two prominent concerns among motorists considering the switch to electric mobility.<\/p>\n The 50Ah 35kWh electric car battery was tested using powerful 350kW (800V) DC fast chargers, demonstrating that the battery can reach 80% charge in just over four and a half minutes.<\/p>\n As the first four minutes of charging are at a constant current of 500A, this provides 120 miles of range.<\/p>\n At full charge, the prototype EV can achieve a range of 155 WLTP miles.<\/p>\n Nyobolt’s technology effectively addresses the degradation issues that usually accompany supercharging lithium-ion batteries.<\/p>\n Their 24.5Ah cells have surpassed 4,000 full Depth of Discharge (DoD) fast charge cycles, which translates to over 600,000 miles in a Nyobolt EV pack while maintaining over 80% battery capacity.<\/p>\n This performance far exceeds the warranties of most larger EV batteries available today.<\/p>\n Independent testing by OEMs has verified that Nyobolt’s 2.6Ah cells can endure over 4,400 cycles with a 12C charge and 1C discharge at 23\u00b0C.<\/p>\n Notably, the internal resistance of these cells increases by only 50% after 4,400 five-minute charge cycles, which is lower than the industry standard for the end-of-life values for EV cells, typically doubling the initial resistance.<\/p>\n Nyobolt’s battery assembly plans are highly advanced, aiming for production at low volume within a year and scaling up to 1,000 packs by 2025.<\/p>\n Their flexible manufacturing model supports volumes of up to two million cells annually. The batteries will comply with the EU’s Battery Regulation once in production.<\/p>\n Furthermore, Nyobolt’s EV architecture suggests potential retrofitting to existing EV platforms, promising significant improvements in charge time and battery life cycle.<\/p>\n Nyobolt is actively engaging with eight additional vehicle OEMs to adopt its technology.<\/p>\n Beyond automotive applications, Nyobolt’s fast-charging technology will debut this year in robotics and is also poised for use in heavy-duty commercial vehicles, minimising downtime and boosting productivity.<\/p>\n The UK start-up’s technology could prove instrumental in incentivising motorists to make the switch to EVs, with the UK targeting all new cars and vans to be zero emission by 2035<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":" UK start-up Nyobolt has demonstrated the revolutionary performance of its fast-charging EV battery, which takes under five minutes to charge.<\/p>\n","protected":false},"author":15,"featured_media":48914,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"footnotes":""},"categories":[24425],"tags":[24404,24163],"acf":[],"yoast_head":"\nUnprecedented EV charging speeds<\/h3>\n
