The "fast charging" situation in BCS is about to get much better with a couple of Tesla Supercharger locations (one on campus and another somewhere else...someone mentioned Target in another thread). There are a good handful of hotels that have overnight destination chargers if you are staying overnight as well as destination chargers in most of the campus garages, Bush Library, etc (which should give you enough over a 3-4 hour game).
Brookshire Brothers has a CCS DC fast charger. Gladney's Auto at Highway 6/Harvey Mitchell Parkway currently has a couple of Tesla destination chargers but they are in the process of getting 150kw DC fast chargers installed that will be similar to Brookshire Brothers, but about twice as fast. Mid-South also has a 62kw CCS DC fast charger on Highway 6 in Navasota (at their main office) and one at the Aurora convenience store in Carlos (Highway 30). Both of the Mid-South chargers are actually free. Not super fast, but still about 6x faster than destination chargers.
