TfL finally replied and my application for exemption of the CC is refused. Even though my car meets the CO2 emissions requirement, it doesn’t meet the 20-mile EV requirement (must be table to travel 20 miles with zero emissions.)

They refunded the £10 I paid for registration.

However, I may still be able to get an exemption. Since my dad also uses my car and he’s registered disabled, he may be able to register my car as a blue-badge holder, which gives 100% exemption.
