Is there a difference between electric car batteries and solar cells?

The battery of an electric vehicle is not necessarily a lead-acid battery. Large and medium-sized electric vehicles generally use power lithium batteries. Small electric vehicles, such as elderly scooters, mostly use maintenance-type lead-acid batteries, maintenance-free lead-acid batteries and colloidal lead-acid batteries, and only a few are power lithium batteries.

If you think there is no difference between solar cells and electric vehicle batteries, you are a layman.

Besides, even if the solar cells and batteries used in electric vehicles are lead-acid batteries, there are differences. Lead-acid batteries of solar energy require deep cycle discharge and have extremely long life, so lead-acid colloid batteries are commonly used; However, the lead-acid batteries of electric vehicles do not need deep cycle and long life, but have the characteristics of large current discharge, so maintenance-free lead-acid batteries and maintenance-added lead-acid batteries are generally used.
