A few points to factor in:
- A nuclear power station has a much longer lifetime than batteries, solar panels, and wind turbines.
- You need not only the batteries, but also the panels/turbines to fill them.
- Conversion and storage losses are significant. Attached is a rough overview for H₂.
- Transmission infrastructure costs to/from individual cars are significant.
- 24 h is not enough by far to balance out usual fluctuations.
