For solar, wind and wave energy there is always a period of time when these technologies go down.  When the Sun sets a solar array can no longer convert photons from sunlight into electricity. When the wind dies wind turbines no longer operate. When there are no waves or tidal action

The most advanced batteries in today’s electric cars are based on lithium-ion technology. These batteries use metal-oxide cathodes combined with an encased oxidizer. They are heavy and provide a limited range, up to 160 kilometers (approximately 100 miles) before they need recha
