The 314-kilometre drive from Houston to San Antonio, taking roughly 208 minutes, is well within the real-world range of most modern EVs, even in Houston’s hot climate, which can reduce battery efficiency due to increased air-conditioning use. With 131 charging stations available along the route, drivers have abundant options for top-up stops, though a single charge at the start should suffice for the entire journey. San Antonio, with 35 stations in the city, offers adequate destination charging, while Houston’s 117 stations provide a strong departure point. The route is not cross-border, eliminating any customs or charging connector concerns. For EV drivers, the flat terrain of this Texas corridor minimizes elevation-related range drain, making the trip straightforward. However, planning a brief charging stop midway could provide a buffer against Houston’s heat-induced range loss, ensuring a stress-free arrival in San Antonio without relying on the city’s smaller charging network.
