List the charging history and the solar percentage
New feature: list the charging status and history in IAMMETER
Charing your EV by solar excess + grid power
List the solar percentage in charging history
Chargers-> Charging history
The charging process may be powered by the grid or the solar.
This table will show you the charging history and the percent of solar in each charging process.
The different solar percent are caused by the different threshold setting in charging process.
You can set the threshold (maximum grid power in the charging process) in IAMMETER. When the grid power is exceed than the threshold setting ,IAMMETER would stop the charging until the solar output is enough again.
If you set the threshold to zero, it means the charger would only use the solar to charge the EV. It would be the cheapest charging mode, but would take more charging time.
For how to understand the threshold, please refer to Charge the EV by the solar surplus
List the hourly solar percentage in charging
Chargers-> Charging history->Statistics
EV charger is one of the best actuators in this solution because the charging power can be controlled nearly linearly. Based on the reading of the meter on the grid side, you can get the solar excess output, then you can control the charging power , as nearly to the solar excess power as possible.
