How Far Batteries Have Come

Fenix is working to help solve big problems for many EV owners with aging batteries, and it’s easy to get caught up in that. What’s harder to see at times is just how far EV battery technology has come in just a few years. Taking a vehicle from a few years ago and adding today’s battery technology can make a huge difference!

One thing I saw at the Ford Mustang Mach-E unveiling really drives this home.

On the bottom is Ford’s first generation hybrid battery pack from a 2005 Escape (made in 2004). The pack is huge, heavy, and hard to fit into a vehicle without either giving up a lot of room or designing it from scratch to fit around it.

Compare this to the 4th generation Ford hybrid battery pack that went in various newer vehicles (the smaller pack on top in the photo). It’s smaller, liquid cooled, and fairly easy to fit in a variety of different places. Little (if any) cargo or passenger room is lost to such a battery.

Most important of all, the small pack holds more energy and does more work than the one on the bottom.

Yes, this image shows us Ford’s advances, but it’s reflected in the industry as a whole. The EVs of 2005 (like the EV1) could only go a few dozen miles. With better batteries today, EVs are able to go hundreds of miles and charge far faster than ever before.

The great thing about taking an older Nissan LEAF (not that far off of 10 years old now) and giving it new batteries is not only about restoring lost range. Newer batteries are more compact, weigh less, and cost far less per kWh of storage than they’ve ever been. By upgrading your degraded pack, you can get all of these advantages and bring your car much further into the 21st century.
