Service Calculation for EV Charger

[yargnits67]

Hello folks,

I am trying to determine if I can add an EV charger in my garage. I'm just learning about calculating load and came up with the following by looking at my breaker panel in the garage:
House 2626sqft: = 7878
A/C: 50 amp = 4800
Range: 40 amp = 3840
A/H: 35 amp = 3360
W/H/Dryer: 30 amp = 5760
20 amp (11) = 21120
15 amp (10) = 14400
Total = 61158 / 240 / 1.732 = 148amps

Panel outside of house where electricity enters home:
Pool: 30amp = 5760
Irrigation: 30amp = 5760

Grand total = 72,678 / 240/ 1.732 = 175amps.

I have a 200amp service and I've read I need to maintain no more than 80%.

I would like to install a 50amp EV charger but I'm already over the 80%.

I'm hoping because I have zero clue what I am talking about and doing that I did some calculation wrong.

Thanks,
Joe
