I often get a “Charging limited by temperature” message on summer days. It’s great that the unit has this protection, but as a future feature, it would be good if there was a relay inside the unit that would through software configuration be set to “close” when the temperature reaches a point that would limit the charging rate. This relay function would be off by default so would not effect anyone not using it.
This is not to provide power, just close a 12v relay. 12v relays can handle decent loads, and this could be used to either switch the power to a small computer style fan for either direct airflow, or for area exhaust, or as a signal for a smart home.
Hi there, thank you for your feature recommendations. I will have a discussion with our hardware team and come back to you. We are working on Firmware updates in regard to heat tolerances. Are you please able to email me at support@evnex.com with your charger SN details and I can take a look further in to this for you? Have a great day!
This is a good concept. Clean and practical would be a software-controlled 12-volt relay connected to the internal temperature sensor, particularly for activating a fan or smart home input *before* temperature limits charging.
crucial thing is hysteresis so the relay doesn’t chatter (close at X°C, open at X–5°C). The best course of action is to maintain it low-voltage exclusively; nobody should switch mains from this.
If temperature data is already available, firmware-wise, it is insignificant. off by default, customizable threshold, done. lot better than external temp probes and clever relays.
