About

EV Smart Charging is an integration that charges an electric vehicle when the electricity price is lowest. It calculates the set of 15-minute intervals with the lowest price, by default limited to one continuous block, once tomorrow's prices are available or before the configured completion time. Prices can come from several price integrations, such as Nord Pool, Energi Data Service, GE-Spot, Entso-e and TGE, or from a template sensor in a generic price format. Optional settings cover a minimum battery level, a price limit, and starting at once when the price or battery level is low. It adds buttons to start and stop charging manually, number and select entities for levels and start and completion times, and switches to enable each charging mode. It works locally and is set up in the UI.

From the README

The EV Smart Charging integration will automatically charge the electric vehicle (EV) when the electricity price is the lowest. The integration can get the electricity price information from a large number of integrations or from a template sensor that supports the generic price format.
The integration calculates the set of 15-minute intervals that will give the lowest price, by default restricted to a continuous set. This calculation is done when the electricity prices for tomorrow is available (typically between shortly after 13:00 CET/CEST and midnight) or when the time of the day is before the configured charge completion time.
Automatic EV charging control based on electricity prices.
Can automatically detect and use instances of the (HACS) Nord Pool, Energi Data Service, GE-Spot, Entso-e and TGE integrations.
Supports manual configuration of other price integrations that fulfills the listed requirements.
Supports a generic price format. A template sensor can be used to get price information from price integrations without native support and/or to construct other special price information.
Supports price information given with 15 minutes and 60 minutes intervals.
Configuration of the latest time of the day when the charging should be completed, and the earliest time the charging can start.
Selection of preference between one continuous charging session or several (possibly more price optimized) non-continuous charging sessions.
