Electric vehicles are central to the UK target of zero tailpipe emissions by 2050. However, incremental improvements to battery capacity cannot address power requirements (>1.2kWh/km) in demanding applications such as logistics, mass transport and aviation. Electrification of mobility in demanding applications is therefore critically dependent on capability to safely and rapidly supercharge high energy (>40kWh) batteries to full capacity in <15 minutes. Existing charging technologies cannot meet this need and are fundamentally limited by the continuous rate at which current can be forced into a battery against the internal electrochemical impedance of each cell.In response, Petalite Limited have developed and patented a new technology platform – Sinusoidal DC Supercharging – which radically reduces cell impedance and temperature using a time-varying current to the battery, synchronised with the AC grid. PL now seek to realise a scalable solution enabling adaptive supercharging of high power multi-cell Li-ion battery packs in less than 15-minutes, targeting electric mobility and EV applications with a step change in function, performance, safety, complexity, reliability and cost. Sinusoidal DC Supercharging can therefore be a transformative platform technology enabling electrification of mobility in demanding applications.
