B2U

Also called: battery second use B2U means battery second use, the reuse of an EV traction battery in another application after it leaves its original vehicle role. Stationary energy storage is a common second-use application because weight and packaging constraints are less severe than in a vehicle. A battery can leave automotive service while retaining useful capacity for a less demanding duty. Reuse can extend the service life of the pack before material recycling. B2U should not be confused with remanufacturing or recycling. Those are different end-of-first-life routes.
