Advantages and disadvantages of bidirectional charging for energy storage containers

Can bidirectional charging transform EVs into mobile energy storage units?

According to the document, “bidirectional charging has the potential to transform EVs into mobile energy storage units, unlocking substantial value across the energy ecosystem.” To help people ‘navigate’ the complexities of bidirectional charging, the document includes eight so-called one-pagers, looking at the different applications.

Does bidirectional charging make sense?

In addition to the stakeholder perspective, bidirectional charging also makes sense and is cost-optimized from a system perspective. The bidirectional development of the existing storage ca-pacity in electric vehicles for the energy system reduces the energy supply costs in Europe com-pared to a scenario without bidirectional electric vehicles.

Why is bidirectional charging important for electric vehicles?

The flexibility of electric vehicles can be used by means of bidirectional charging in numerous applications to promote self-sufficiency, save costs and support the energy sector via grid and system services.

Does bidirectional storage reduce energy supply costs in Europe?

The bidirectional development of the existing storage ca-pacity in electric vehicles for the energy system reduces the energy supply costs in Europe com-pared to a scenario without bidirectional electric vehicles. The use as daily storage improves the system integration of renewable energies and PV energy in particular.
