ALTABATT+ processes retired lithium batteries from electric vehicles to manufacture solar energy-storage units.
BROUGHT TO a second life
After an average of 5 years of service in EVs, where batteries are subject to extreme operating temperatures, hundreds of partial cycles a year and changing discharge rates, lithium-ion batteries are normally retired due to faded capacity and power that fails to meet EVs range requirement.
Yet these batteries can live a second life 3-4 times longer, even when they no longer meet EV performance standards, which typically include maintaining 80 percent of their total usable capacity and achieving a resting self-discharge rate of only about 5 percent over a 24-hour period.
OUR GOALS
Our strategy is two-fold:
– Manufacture high-quality low-cost energy-storage systems for solar PV installations.
– Become a key European player in the re-manufacturing of retired EV batteries.
OUR UNIQUE APPROACH
Currently there are two existing approaches to deal with EV batteries retired from service. First, they can be recycled to extract raw materials. Second, batteries can also live a second life in less-demanding applications such as stationary energy storage systems (ESS) before being recycled. This is what is called “second life” or repurposing.
ALTABATT+’s founders have developed a new technology allowing a more efficient use of retired EV batteries: they can be re-manufactured into high-quality, low-cost ESS with enhanced performance, reliability and safet
