My 2 cents comment that may save you many thousands. I also thought that I need to upgrade my service from 125A to 200A. Turns out I don’t!!! I installed an Emporia Pro that cost me $599. I added the dual pole circuit breaker and that was all my cost since I know this stuff. But even if you hire an electrician that would be under $1000 for his labor. How this works? The Emporia Pro reads in real time the total amps the whole house takes, and subtracts it from the service amps that you need to program. Then the result is the max amps it allows for the car by sending a signal to the car to reduce the amps it takes if you have some very high loads running at the same time in your house. The probability that it actually activates this reduced amps is very low because almost never do I run so many heavy loads at the same time. Read more about it online. Read the reviews at https://a.co/d/06vajmsX I am very happy with it and can confirm the 4.8/5.0 score on Amazon is real. Don’t upgrade the service, you don’t need. Keep your hard earned money for better things you really need. Call Emporia and ask for their professional advice what solution they recommend for your exact situation: https://www.emporiaenergy.com/contact Plus they can recommend an installer who is familiar with their products. BTW, you will not get the best solution from electricians because they a) may have never heard about Emporia and b) it is not in their financial interest to quote you the lowest cost solution even if they would know about Emporia. And my last point: don’t hurry or you will overpay for a mediocre solution! You have time to get yourself well informed. Allow yourself 2-3 weeks or even more before you decide. Keep us posted. Good luck!
Not an electrician, but an engineer who has done a lot of electrical work, both industrially and DIY. I see a lot of small, tandem breakers. Likely for ordinary HVAC and misc mechanical, living spaces, bathrooms, and kitchen. For big appliances I see a 40 amp (stove?) 60 amps (hot water heater?), a 20-15 amp double tandem breaker (heat pump dryer or maybe AC?). So long as your household isn't more than 3-4 people AND you're not slamming the water heater 24/7, I'd say its perfectly fine. I would do it. But if this is a large household and you're concerned, they actually sell EV chargers that can automatically make sure you aren't exceeding the houses' 200 amp supply: https://www.amazon.com/dp/B0D9MQ736J Regardless, so long as the wire is 6awg or higher (looks like it is), I'd say go for it.
