Panasonic's 18650 Lithium-Ion Cell For Tesla Model S
SAE International, using Lux Research's lithium-ion battery report, released price outlook at the pack level.
Most sources indicate Tesla Motors (Panasonic cells) as the leader in price per kWh, while the industry average stands at some $400/kWh.
"The Lux report estimates that by 2025, Li-ion EV battery pack prices from a leading manufacturer such as Panasonic should fall to $172 kW·h, while the “laggard manufacturers” should achieve pack prices around $229/kW·h. Most automotive packs currently cost around $400/kW·h.
Laslau said a $200/kW·h pack price is considered to be the entry point to a large-scale EV market. EV sales would truly take off at a $100/kW·h price point, according to the U.S. Advanced Battery Consortium."
Battery costs are kept secret, so we not only don't know the true value, but there is no way to forecast prices in the future, because we don't know the technology of the future or other factors.
Broad take off could begin at $250/kWh, which enables 50 kWh packs for $12,500 for well over 150 miles of EPA range.
