Hello,
I want to share a few considerations about the EV Charging Station integrated into an ESS (*) Victron system:
- In some specific situations the Manual and Automatic mode are not enough open to manage the charge according to the user needs, especially in partly cloudy days.
- In Automatic mode there must be options to choose which should be the priority for the solar production, for example:
- Charge first the ESS battery or EV battery.
- Charge the ESS battery first, until a certain % of SOC, then charge the EV battery.
- Charge botch batteries at the same time, using a certain % of the solar production (adjustable by the end user) to charge the EV battery and the rest to charge the ESS battery.
- A new Semi-Automatic mode, should be implemented, for the situation that you want to charge the car with the surplus solar production, but you want to charge the car anyway, could be something like this:
- Once it has started to charge, if the clouds appear and there is no surplus power, the charge is limited to 6A or more (adjustable by the end user), with a timer limit (also adjustable by the end user) if the sun doesn’t come back to really shut it down.
- In this mode the priority should be to charge the EV battery.
- The ESS battery should never be used to charge the EV battery.
- The communication between the EV Charger and the Cerbo GX is non reliable despite the wifi signal is strong, sometimes work, sometime doesn’t.
Furthermore, If the router is reset, both the EV charger and the GX reconnect to the wifi, but the EV Charger usually doesn’t reconnect with the GX. Before setting static IPs to both, the EV Charger never reconnected to the GX, with static IPs it seldom (randomly) reconnected.
Could be great to allow a RJ45 data connection for the charger (or via VE direct), selling a hardware upgrade to who already owns the EV Charging Station, and adding it to future batches.
- The screen is very unresponsive.
Does anyone know if the Victron development team is working to make some of these improvements?
Thanks for reading.
