A company named Phinergy mounted such a battery in a subcompact demonstration car that provided 1,000 miles of range. The second scenario is all this investment results in a true battery breakthrough, like the Aluminum-air battery. We'll call this scenario: Linear Lithium-Ion. The technology is essentially the same, but improved on a linear scale from now until 2020. The first scenario is, in 2020, I purchase some type of improved Lithium-Ion based battery. I can come up with many more, but four is a nice number. What will the range, cost, size, and charge time be in 2020? To simply, I limited myself to four scenarios. What will batteries be like in 2020? Globally, there are billions of investment dollars racing to invent the best car battery. Since I purchased my Volt in 2012, that means it will be 2020 when I'm in the market for a replacement battery pack. Additionally, I imagine GM may "unlock" more of the battery capacity with a future software update, enabling the Volt to keep the same driving range over time by using more of the battery.įor this exercise, lets assume I want to replace the Chevy Volt battery in 8 years (the length of the warranty). Given the Toyota experience, the Volt battery should last for many years. We know from the Toyota Prius design, which only uses 50% of its battery's capacity, that using only part of the battery's capacity allows it to last a lot longer. Given the Volt only uses about 10 kWh of the battery's 16 kWh capacity, it is conservatively designed to last a long time.
