It may be worth mentioning that not all DCFC stations (Level 3, which is really SAE DC Level 2, but that's another story) have the same charging capability (re: rate of charge). But, none of the apps (especially PlugShare) filter by this difference. To the app, all Level 3s are the same.
Similarly, to them, all Level 2s are the same, but we soon learn that, although rated at 240 volts, some are as low as 206 volts. Some Level 2 chargers deliver only 16 amps (11-12 mpch {miles per charging hour} made to fill the needs of the VOLT) while others can provide the full 32 amps (24-25 mpch) that the BOLT can take. [A 40 amp home or commercial EVSE will not charge a Bolt any faster than a 32 amp EVSE will.]
Even without a filter, if each of us, when using a Level 3 DCFC station would comment on the wattage (volts x max amps) we could adjust our travel plans. All DCFC supply diminishing amps as the battery fills, sometimes from 100 amps at the start down to 5 amps at finish (if charging to "full"). Charging rate diminishes also such that you rarely charge for more than an hour, or above 80% SoC. Drive on to the next station. You will spend less time charging in the long run.
