I did a little search and found this Tesla forum post suggesting that Teslas won't use regenerative braking when the battery is full: https://teslamotorsclub.com/tmc/threads/tesla-should-update-firmware-to-allow-regen-braking-when-battery-is-full.166129/ https://teslamotorsclub.com/tmc/threads/tesla-should-update-... > "most of us charge to a user-specified software limit of say 70%, 80%, 90%, etc. When you first set out on your next drive after charging to that capacity there's a warning that regenerative braking won't function 100% until some juice is used up to make room."
