Toyota launches project to reuse old Prius batteries

Toyota is to examine how to make the best use of used electric and hybrid car batteries, and intends to build a 10,000kW storage battery comprised of 10,000 old Prius and iq EV batteries.
That storage battery would absorb surplus electrical power from the grid during times of low use, and also store energy generated by renewable sources such as wind and solar farms, which can have unpredictable generation patterns. The stored electrical power would then be fed back into the grid during times of high demand.

The new scheme is being developed by Toyota in conjunction with Japanese utilities company Chubu electric Power, and will see a “verification project” launched this year. If this is successful, the large storage battery will be built in 2020.
Toyota says used batteries “even with decreased performance levels” can “handle adjustments in energy supply and demand”, allowing electrical power providers to “manage frequency and voltage fluctuations in power distribution systems.”
The large majority of the batteries used by Toyota’s new scheme will be nickel-metal hydride (NiMH) units, taken from old hybrid cars such as the Prius. but the company estimates that by “around 2030”, much more sophisticated lithium-ion (Li-ion) batteries from future electric cars and plug-in hybrids will be used.
Toyota’s new project follows a similar scheme from Nissan, whose ‘second life’ battery project has seen old leaf batteries offer backup power to the Amsterdam Arena, home of football club AFC Ajax.
The joint venture between Toyota and Chubu electric Power will also see rare-earth metals collected from old batteries, allowing these expensive elements to be reused.
