What Is the Audi Long Bess Battery System and How Does It Enhance EV Performance?
The Audi Long BESS (Battery Energy Storage System) is a stationary energy storage solution utilizing new and repurposed second-life electric vehicle (EV) batteries. It enhances sustainability by storing excess renewable energy, improving grid stability, and extending battery life. While not directly boosting in-car EV performance, it supports a broader clean energy ecosystem and efficient renewable integration.
What Is the Audi Long BESS Battery System?
The Audi Long BESS is a stationary energy storage installation composed of lithium-ion batteries, including second-life EV batteries with over 80% residual capacity reused from Audi’s development vehicles. Connected to the electrical grid, it stores large amounts of energy for later use, aiding in balancing power supply and demand.
How Does Audi Use Second-Life EV Batteries in the Long BESS?
Audi collaborates with energy partners to repurpose EV batteries once they no longer meet automotive standards but retain sufficient capacity for stationary use. This approach extends battery utility, maximizes resource efficiency, and reduces environmental impact by delaying battery recycling or disposal.
Why Does the Long BESS Not Directly Impact EV Performance?
The Long BESS is designed as a grid-connected stationary facility, not as an onboard system for vehicles. Its function is energy storage and management external to EVs, focusing on supporting renewable power availability and electrical grid reliability, indirectly benefiting EV charging infrastructure and energy sustainability.
What Are the Performance Benefits of the Audi Long BESS System?
The system enables cost-effective energy storage by capturing surplus solar or wind generation to be used during peak consumption or when renewable output halts, improving grid stability, reducing reliance on fossil fuels, and buffering intermittent renewable power.
When Is the Long BESS Used to Support Renewable Energy?
It is especially valuable during periods of high renewable generation and low demand, storing excess electricity for release during peak demand or low renewable output, thus smoothing the availability and reducing blackout risks.
