Tesla announced that it will dramatically reduce the cost of its battery cells and packs — which means the company’s new goal is a $25,000 electric car. The company’s CEO Elon Musk said its new “tabless” battery cells, as well as by changing the materials inside the cell, will allow Tesla to “halve” the price per kilowatt-hour, which will make electric cars roughly the same price as combustion engine ones.

The price per kilowatt-hour (kWh) is the unit of energy most commonly used to measure the capacity of the battery packs in modern electric vehicles. Those prices have been falling dramatically over the last decade, from $1,100/kWh in 2010 to $156/kWh in 2019, a drop of 87 percent.

Experts predict that the price will hit $100/kWh by 2023, but Musk said Tesla will kick off a three-year process to bring the price below that — though he didn’t say exactly what the price target would be.

There is more to a battery than just its cells. A lithium-ion battery cell that costs $100/kWh to produce means a battery pack, with its additional components such as a battery management and cooling systems, could cost $125–$130/kWh or more.

Today’s battery packs cost around $10,000–$12,000, depending on their capacity. Low battery prices could be the key to unlock more affordable, higher volume electric cars. Tesla is aiming to reduce the cost of future packs to less than $6,000, which would put the cell cost at well under $100/kWh.

The average price of electric cars in the US has been dropping, most recently from $64,300 in 2018 to $55,600 in 2019, a 13.4 percent decline. And that’s mostly thanks to Tesla’s Model 3. But that’s still high compared to the average price of a regular, gas-burning vehicle at $36,600 (though that price has been ticking upwards).

The Model 3 was supposed to be Tesla’s first car for the broader market. From early on, the company’s “master plan” — as set out by Musk in a 2006 blog post — outlined how it would build a desirable electric sports car to convince people that EVs can be cool (which was not an easy task at the time), use the revenue from that to help fund a more affordable luxury sedan, and plow the funds from that effort into a car that hundreds of thousands of people could buy.

But the $35,000 Model 3 took months to reach customers, thanks to the company’s well documented “production hell.”
