BYD has introduced its Super e-Platform which looks to have a big impact on the charging potential of electric vehicles (EVs). The platform, featuring a 1,000V vehicle architecture, enables charging speeds comparable to refuelling a petrol car and can add two kilometres of range per second.
Impressive Charging Speed
The system is based around a megawatt charging capability (1,000kW) which gives it the highest peak charging speed in a mass-production EV. This means that a five-minute charge provides 400 kilometres of range. Charging anxiety is a big hurdle for many drivers thinking about switching to EVs so this could be a huge leap forward in the transition to sustainable motoring.
“To completely eliminate users’ charging anxiety, our goal is to make EV charging as fast as refuelling a gasoline car – achieving ‘oil-electric parity’ in charging speed. For this parity to be realised, charging needs to combine both ultra-high voltage and high current. Super e-Platform is the world’s first mass-produced passenger car platform to feature an “all-domain kilovolt high-voltage architecture”
Wang Chuanfu, Chairman and President of BYD Group
Performance and Power
The platform debuts in the HAN L and TANG L models for the Chinese market. A 580kW power output and a top speed exceeding 300 km/h in both of these models are achieved thanks to a newly designed 30,000rpm motor.
Battery and Chip Technology
BYD’s Flash Charging Battery allows for ultra-fast charging through an advanced ion channel design, supporting up to 1,000A current and a 10C charging rate. Along with this is BYD’s industry-first silicon carbide (SiC) power chip, capable of handling 1,500V, further optimising efficiency and performance.
Charging Infrastructure
To maximise the potential of the Super e-Platform, BYD has developed a liquid-cooled megawatt flash-charging terminal capable of delivering 1,360kW. The company plans to roll out over 4,000 of these stations across China while also introducing dual-gun charging technology which would allow existing fast chargers to be upgraded instantly to ultra-fast levels.
