Most chargers have Dynamic Load Management readyness where they have a Modbus power meter at your main circuit breaker and makes sure the charger only uses available power. So you can switch on your oven and car will automatically back off. For this kind of consumption tho I would consider installing solar panels if that is possible/feasible.
