The early Nissan Leafs (the first modern EV) had a short battery life, leading denialists to snigger and carp about the failed EV revolution. These days, Leaf batteries are fine, and as the technology advances, we are heading towards a super-long battery life.
From the BBC:
A Chinese car battery-maker says it is ready to manufacture a product capable of powering a vehicle for 1.2 million miles (two million kilometres) across the course of a 16-year lifespan. By contrast, most automakers only offer warranties ranging from 60,000 to 150,000 miles over a three to eight-year period on their cars' batteries.
Contemporary Amperex Technology has not revealed who it intends to supply. But it was previously reported that the battery was co-developed with Tesla. The latest news was revealed in an interview Catl's chairman gave to the Bloomberg news agency.
"If someone places an order, we are ready to produce," it quoted Zeng Yuqun as saying. He added that it was set, however, to cost a 10% premium over the batteries it already supplies.
Demand for electric vehicles is growing. The European market for EVs and plug-in hybrids grew by 72% in the first three months of the year compared to the same period in 2019, representing 7% of all delivered new cars, according to research firm Canalys. By contrast, the pandemic weighed on the wider market, which as a whole saw deliveries down by 26% for the quarter.
My comments:
- The battery costs just 10% for a ten-fold increase in battery life. This dramatically cuts the cost of the battery over its lifetime, which ...
- ... cuts the running costs of EVs, which are already half those of petrol(gasoline)/diesel vehicles. The batteries will last longer than the cars. And, remember, even when the guarantee runs out, some 60-70% of the battery's capacity will still remain.
- It will also cut the cost of storage for grid stabilisation.
- EV sales up 72% in Q1/2020 in Europe, 7% of all car sales now plug-ins (i.e., it excludes ordinary hybrids)!
