Battery degradation in Vehicle-to-Grid (V2G) systems can impact the profitability of V2G operations and is influenced by cyclic aging and calendar aging.
Cyclic aging, affected by factors like charging cycles, speed, energy per cycle, etc., results from charging and discharging cycles.
Calendar aging, dependent on the battery's physical age and State of Charge (SOC) at rest, can be accelerated if the electric car is frequently parked with a high SOC.
The impact of V2G on battery degradation compared to other charging methods is uncertain, with studies suggesting V2G may accelerate cyclic aging.
Charging without smart technology considering the SOC can intensify calendar aging effects.
Research challenges exist due to the time-consuming nature of low-power charging cycles for studying battery degradation.
Electric car manufacturers are keen on research collaborations to assess battery warranty designs concerning bidirectional charging practices.
