Tesla Inc CEO Elon Musk has promised a new version of the company’s Autopilot system at the company’s “Battery Day”, even as he tempered expectations that Tesla’s electric vehicles will soon surpass the cost and convenience of traditional petrol-powered cars.
“We do not have an affordable car. That’s something we will have in the future. But we’ve got to get the cost of batteries down,” Musk said on Tuesday.
Musk described planned improvements intended to cut the cost of battery cells in half. Those include changes to electrode materials, as well as improved cell design, production processes and integration into vehicles.
At the opening of the event, which drew over 270,000 online viewers, Musk walked on stage in a black t-shirt and jeans as about 240 shareholders — each sitting in a Tesla Model 3 in the company parking lot — honked their car horns in approval.
Musk said Tesla plans to release a revised “full self-driving version” of Autopilot in a month, “then people will really understand the magnitude of the change”.
Ahead of the event, Tesla shares closed on Tuesday at $US424.23 ($A586.93), down 5.6 per cent after Musk tweeted on Monday that the battery improvements to be unveiled at the event would not reach “serious high-volume production” until 2022. Shares rose 3.2 per cent in after-hours trade.
As automakers shift from horsepower to kilowatts to comply with stricter environmental regulations, investors are looking for evidence that Tesla can increase its lead in electrification technology over legacy automakers who generate most of their sales and profits from combustion-engine vehicles.
Musk in July said scaling battery cell production at an affordable price was Tesla’s biggest limitation to growth.
While average electric vehicle prices have decreased in recent years thanks to changes in battery composition, they are still more expensive than conventional cars, with the battery estimated to make up a quarter to a third of an electric vehicle’s cost.
Some researchers estimate that price parity, or the point at which electric vehicles are equal in value to internal combustion cars, is reached when battery packs cost $US100 ($A138) per kilowatt hour (kWh).
Tesla’s battery packs cost $US156 ($A216) per kWh in 2019, according to electric vehicle consulting firm Cairn Energy Research Advisors, which would put the cost of a 90-kWh pack at around $US14,000 ($A19,369).
Analysts at UBS expect Tesla to announce battery cell costs of $US70-80 ($A97-111) per kWh over the next three years, allowing the company to save roughly $US2300 ($A3182) per vehicle.
Such a price advantage would leave competitors unlikely to catch up to Tesla, the UBS analysts said.
Tesla currently produces batteries in partnership with Japan’s Panasonic Corp at its $US5 billion ($A6.9 billion) Nevada factory, while South Korea’s LG Chem and China’s CATL supply cells to its Shanghai factory.
Tesla is also building its own cell manufacturing facility at its new factory in Germany and is setting up a battery research and manufacturing facility at its largest vehicle factory in Fremont, California.
Musk in July also said Tesla was open to licence and supply powertrains and batteries to other automakers.
