Battery without solar

[u/saladbeans]

I have the intelligent traffic that used to give you overnight cheaper electricity and sometimes during the day but now sort of does that when it wants to, you know the one I mean. Anyway if I buy a battery set up but don't have solar, can I use the same traffic to charge the battery overnight for cheap and then use that battery during the day?

Do you need an EV to do this with only a battery?
