Sub panel breaker amperage upgrade

[Deonvas]

I need to install a charger for an electric car, which needs 60 amp breaker. My main panel has a 200amp breaker and services 2 sub panels, both via 60 amp breakers. My issue is that there is no space in the main panel for a 60A 240V breaker. I do have space in one sub panel (basement) which is ideally situated to service the charger in the garage. The cable to this sub panel is ‘AL type se style r type xhhw 600 3 cdrs 2 awg’. Would I be able to change the breaker serving this sub panel from 60 to 90 amps in the main panel, then add a 60A breaker in the subpanel for the charger?

Pictures would be nice but do not change that breaker to a 90 amp. You can buy slim line breakers and free up space. Just because you have to install a 60 amp service, don’t mean that it’s going to pull 60 amps. At best it will pull maybe 25- 35 amps maximum
