The vast Chinese BYD concern (Build Your Dreams, if you’re interested) is about to revolutionise EV charging. Within the next 18 months it will install over 300 of its new Flash chargers, capable of delivering a 1500kW hit to your EV’s battery, about four times quicker than the fastest chargers currently available. It says it can charge its Denza Z9 GT from 10% to 70% in five minutes flat, and is equating its recharging rates as now being not in the least dissimilar to refuelling speeds for ICE cars.
But there’s a catch: no car on sale in the UK is able to receive anything like that rate of charge. The fastest, like Porsches, Audis, Hyundais, Kias and Lotus EVs, are all rated at around 350kW, so they won’t see much difference.
As ever with the Chinese, they are thinking long-term and the Denza Z9’s market debut in the autumn is just the start. What BYD is aiming to do is essentially what Tesla did at the start of the EV revolution, namely install a game-changing charging network that will be ready to receive the next generation of EVs able to take that level of power, rendering all pre-existing infrastructure obsolete. While for now it’s going to make little difference, in a few years you’re not going to want to charge anywhere else.
On that note, I took an Audi e-tron GT to Scotland for a short walking holiday and found the car a near perfect partner for such a trip: quiet, fast and always pleasant to drive. But the charging process was horrendous: not one charger I used all the way there or back delivered more than half its advertised speed. Plenty didn’t work at all, and at Tebay the queues were so long I had to crawl to the next services. On the way back just getting enough juice into the car added a minimum of 90 minutes to an already long journey. My EV-centric friend says I was unlucky, and my own worst enemy for not stopping to charge when recommended by the car. But should a car not do what I want it to do, rather than the other way around?
