EVwire brief: Tesla has launched its Semi Charging for Business program, offering Megacharger and Basecharger systems for fleet operators. It’s like the Supercharger for Business program, but Tesla Semi-sized.
Tesla provides design support, optional installation, and ongoing network services, including monitoring, pricing controls, maintenance, and driver support through its software platform.
The system is designed to support both small fleet depots and large-scale logistics hubs.
Pricing starts at $40,000 for two Basechargers and $188,000 for a Megacharger system with two posts, excluding taxes and installation.
Tesla Senior Director of Charging Max de Zegher described the program on X:
Context:
Tesla’s Megacharger is built for high-throughput fleet charging. A cabinet paired with two posts delivers up to 1.2 MW DC output (shared), with a voltage range of 180–1000 VDC and efficiency above 96%.
The system supports distances of up to 100 meters between cabinet and post and uses liquid-cooled hardware designed for continuous operation.
The Tesla Megacharger features an efficiency of above 96%
The Basecharger is positioned as a lower-cost option for depot or “home base” charging for the Tesla Semi. It delivers 125 kW, adds up to 60% range in four hours, and integrates AC-to-DC conversion into a single unit. Deliveries are expected to begin in early 2027.
See how the Megacharger and Basecharger are white-labeled, just like the posts deployed in the Supercharger for Business program. This suggests businesses can put their logos on their own Megachargers and Basechargers.
The Megacharger delivers 1.2 MW, adding up to 60% of range in 30 minutes
The Basecharger delivers 125 kW, adding up to 60% range in four hours
Both systems support MCS 3.2, open communication protocols including ISO15118-2 and OCPI, and receive over-the-air updates. Tesla said the chargers include the same hardware, software, and service stack used in its own network, with uptime targeted above 97%.
Cost structures scale with deployment:
Megacharger: ~$179,000 hardware + $9,000 services/shipping = $188,000 total
Basecharger: $31,000 hardware + $9,000 services/shipping = $40,000 total
Bulk deployments reach up to 100 posts (~$9.4M) for Megachargers or 100 Basechargers (~$2M).

An end-to-end Tesla Semi charging solution
Tesla’s Semi charging program is designed as a full-service solution for fleet operators, covering deployment, operation, and ongoing support. Businesses can order systems with a minimum of two charging posts, with Tesla providing design guidance or full installation support.
Tesla highlighted these on the service’s official website:
Once deployed, operators can manage site performance through Tesla’s software platform, including monitoring utilization, adjusting pricing, and tracking operations. Tesla also handles maintenance, network operations, and driver support, with uptime targeted above 97%.
Both Megacharger and Basecharger systems include the same hardware, software, and pricing controls used across Tesla’s own network. The chargers receive over-the-air updates to improve performance over time, positioning the system as a managed infrastructure layer rather than standalone hardware.
