Sprint Power to Lead on New UK Government Backed Project to Develop Ultra-fast Charging Systems for EVs
· Sprint Power awarded funding to develop ultra-fast charging solutions for electric and fuel cell vehicles
· Next generation 800V ‘battery platform’ to deliver an 80% charge in just twelve minutes
· Project CELERITAS consortium to include BMW, bp, AMTE Power, Clas-SiC and Eltrium
· Project a key part in UK government’s plan for zero tailpipe emissions by 2035; project begins in November
Sprint Power, a leading British technology company specialising in low carbon tech, including electrified propulsion systems, power electronics and battery systems, is leading on a new £9.7 million UK government-backed project aimed at developing ultra-fast charging cells and battery packs for battery electric vehicles (BEVs) and fuel cell hybrid electric vehicles (FCHEVs). These products will aim to address existing consumer concerns relating to the charging speeds of today’s electric vehicles.
Funding for Project CELERITAS is being jointly delivered by the UK’s Advanced Propulsion Centre (APCUK), as well as each consortium member. APCUK is a non-departmental public body funded by the UK government aimed at creating the technologies for a cleaner automotive future, while also ensuring the UK remains competitive in the global race to reduce CO₂ emissions. In addition to Sprint Power, the consortium includes BMW, bp, AMTE Power, Clas-SiC and Eltrium.
Sprint Power will design and develop an 800V ‘battery platform’ for high performance and mass market EV and FCHEV applications that will integrate all system electronics and incorporate multiple charging protocols. Targeting BMW’s future battery specifications and requirements, the battery platform will bring together innovations from each partner, including rapid charging cell technology being developed by AMTE Power, bp’s thermal management and next generation EV fluid technology, 1200V silicon carbide switching devices from Clas-Sic, Eltrium’s advanced 800V manufacturing capabilities and Sprint Power’s own 800V DC-DC converter and battery management system (BMS) technologies.
The project will deliver two battery systems, one for BEV applications and one for hybrid applications. The systems will include an integrated 800V to 14V DCDC converter, an 800V BMS and multiple charging interfaces that will include provision for wireless charging in the future. The platform architecture will be suitable for applications in multiple sectors, further opening the potential to service applications ranging from commercial vehicles and energy storage systems to the marine, off-highway and aerospace sectors.
The formation of Project CELERITAS comes at a time when UK legislation is targeting zero tailpipe emissions by 2035, including a ban of the sale of new petrol and diesel ICE vehicles by 2030. While the uptake of BEVs is on the rise, there remains a number of barriers that still need to be overcome before more consumers make the switch. While a 150-mile range has been shown as sufficient for most drivers, many consumers would like to see BEVs capable of delivering the equivalent range of a conventional ICE vehicle, as well as a charge-time close to that of filling a traditional fuel tank. As more consumers make the switch to BEVs, the demands put on the UK’s public charging infrastructure is also set to increase. With only 68% of UK households having access to off-street parking to enable home-charging, and current charge-times regularly taking between 22-90 minutes, waiting times at public facilities is likely to increase.
An 80% charge in 12 minutes
While the current best-in-class charging systems take approximately 22 minutes for a 10%-80% charge for a 280-mile range, Sprint Power is aiming for its BEV platform to deliver an 80% charge in just twelve minutes. The ability for consumers to charge their cars in such a short time is seen as key to improving the BEV ownership experience and encouraging more consumers to make the switch.
As more consumers turn to BEVs, the introduction of FCHEVs is also set to increase, requiring HEV battery solutions that can deliver fast charge rates, impressive fuel-cell response times and efficient energy recovery to meet consumer expectations. Sprint Power’s 800V FCHEV battery platform will be designed to enhance efficiency and deliver similarly impressive fast-charge rates as its BEV sibling.
Founder and CEO of Sprint Power, Richie Frost, commented: “As we move steadily towards the UK’s ban on petrol and diesel ICE vehicles, more of us will be making the switch to electric. While there remains a number of barriers that are currently preventing a greater uptake, our involvement in Project CELERITAS aims to make this transition easier for everyone by developing ultra-fast charging solutions for the next generation of EVs. I strongly believe these solutions will be key to this country’s shift towards sustainable mobility.
As well as developing ultra-fast charging solutions for BEV and FCHEV applications, the project also aims to develop the UK’s supply chain to allow UK BEV and MHEV manufacturers to achieve post-Brexit requirements of over 50% parts sourced from UK suppliers within 3 years. Project CELERITAS is due to start in November 2021 and will run for 27 months.
