Replacement Hybrid Car Batteries for all Makes/Models & Years

Published 05/21/2016

Even after they're no longer suitable for their original purpose, the battery packs from hybrids and electric cars can still be useful. Battery energy-storage capacity diminishes over time, to the point where packs are no longer suitable for use in cars. But after their automotive service lives are finished, hybrid battery packs often still have enough usable capacity for other applications.

Like, for example, powering a cluster of buildings in a remote part of Yellowstone National Park. Packs from used Toyota Camry Hybrid batteries will now store energy generated from solar panels at the Lamar Buffalo Ranch field campus within the park.

The system includes 208 Camry Hybrid nickel-metal-hydride battery packs recovered from Toyota dealers, providing a total of 85 kilowatt-hours of storage capacity. Each hybrid battery pack was disassembled and tested before being converted for stationary energy-storage use.The hybrid battery packs were augmented with battery-management systems from Indy Power Systems, re-wired in parallel, and arranged into arrays of 52 packs each.

The solar array used to power Lamar Buffalo Ranch's five buildings generates enough electricity annually to power six average U.S. households, Toyota says. Adding onsite battery packs makes the most of solar power by storing energy for when sunlight isn't available--making for a more dependable source of power.

Micro-hydro turbines--which capture energy from a nearby stream--will be added to the site in 2016 as well. It's also possible to recycle batteries--Toyota has its own recycling program--but repurposing them can have added benefits.

Anticipated growth in the energy-storage business could mean there will soon be significant demand for battery packs to pair with solar arrays. While the nickel-metal-hydride packs used in Toyota hybrid batteries contain precious metals, the higher-capacity lithium-ion cells in electric cars are made from relatively cheap stuff.
