Large-scale storage ensures grid stability.

To continue operating in the PCR market, stationary battery storage systems must meet strict criteria set by transmission system operators. These include sufficient storage capacity as well as a stable and rapid response to power fluctuations.

Despite having been in stationary storage use for several years – some after a previous lifecycle in electric vehicles ¬– the batteries have once again successfully passed this demanding requalification process.

Achieving stable storage capacity requires optimal battery management, which is ensured by The Mobility House’s intelligent trading and operational algorithms. Additionally, the technical expertise and engineering concept from Mercedes-Benz Energy provide the foundation for long-term reuse of these batteries in stationary applications.

When a battery reaches the end of its service life in a vehicle, it typically still retains around 70 to 80 percent of its original capacity. This remaining energy reserve allows an extended second life in stationary battery storage systems.

In addition, first-life battery modules can be maintained in stationary applications as a form of active spare parts storage, ensuring that they remain in optimal condition before being used in vehicles.

The charging and discharging flexibility of electric vehicle batteries plays a crucial role in the transition to a renewable energy system. These batteries can replace fossil fuel power plants and compensate for fluctuations in energy generation from solar and wind power.

Because batteries respond significantly faster than traditional gas power plants, they provide an essential contribution to maintaining grid frequency and power quality, ensuring a stable and resilient energy system.
