Not to fear about charging the battery....China has this figured out. Swapping the batteries in three minutes
Swap shops
There
are around 5 million electric vehicles on the roads, and sales have been rising strongly. This is at best only around 0.5% of the global total, though still in a different league to hydrogen, which had
achieved around 7,500 car sales worldwide by the end of 2019.
Hydrogen still has very few refuelling stations and building them is hardly going to be a priority during the coronavirus pandemic, yet enthusiasts for the longer term point to several benefits over electric vehicles: drivers can refuel much more quickly and drive much further per “tank”. Like me, many people remain reluctant to buy an electric car for these reasons.
China, with electric vehicle sales of
more than one million a year, is demonstrating how these issues can be addressed. The infrastructure is being built for owners to be able to drive into forecourts and swap batteries quickly. NIO, the Shanghai-based car manufacturer,
claims a three-minute swap time at these stations.
China is planning to build a large number of them. BJEV, the electric-car subsidiary of motor manufacturer BAIC,
is investing €1.3 billion (£1.2 billion) to build 3,000 battery charging stations across the country in the next couple of years.
Not only is this an answer to the “range anxiety” of prospective electric car owners, it also addresses their high cost. Batteries
make up about 25% of the average sale price of electric vehicles, which is still
some way higher than petrol or diesel equivalents.
By using the swap concept, the battery could be rented, with part of the swap cost being a fee for rental. That would reduce the purchase cost and incentivise public uptake. The swap batteries could also be charged using
surplus renewable electricity – a huge environmental positive.
Admittedly, this concept would require a degree of standardisation in battery technology that may not be to the liking of European car manufacturers.
The fact that battery technology could soon make it possible to power cars for a million miles might make the business model more attractive.
It may not be workable with heavier vehicles such as vans or trucks, since they need very big batteries. Here,
hydrogen may indeed come out on top – as BloombergNEF
predicted in its recent report.
