Walmart Launches 400 kW EV Fast-Charging Network Across 100 Stores

Walmart recently announced the expansion of its proprietary electric vehicle (EV) fast-charging network to 100 stores nationwide, spanning 20 states. The milestone site is located at the Walmart Supercenter in Monument, Colorado (address: 16218 Jackson Creek Parkway), equipped with eight charging ports — four compliant with the CCS1 standard and four with the North American Charging Standard (NACS) — each capable of delivering up to 400 kW peak power.

Note that most currently available EVs cannot accept full 400 kW input; actual charging speed depends on the vehicle's battery management system and thermal management capabilities. Shayne Wahlmeier, Senior Vice President of Walmart Energy, stated: "Reaching 100 sites marks a significant milestone. Leveraging our extensive physical footprint, we're making charging more accessible for local communities — and expanding how we serve our customers."

Walmart's fast-charging sites typically feature eight to 16 ports, evenly split between CCS1 and NACS standards. The Monument location's eight-port configuration represents a typical setup for smaller- to mid-sized stations. On the hardware side, Walmart deploys two 400 kW-class systems: the ABB E-mobility A400 All-in-One (Swiss-made) and the Alpitronic HYC400 Hypercharger (Italian-made). The Monument site uses ABB equipment.

According to ABB's official documentation, the A400 supports simultaneous dual-vehicle charging — delivering up to 200 kW to each car, or concentrating the full 400 kW to a single vehicle. Alpitronic's unit employs a similar architecture: one host unit integrates both CCS1 and NACS cables to serve two parking spaces. During an earlier pilot at Walmart's McKinney, Texas store, EV expert Tom Moloughney charged the GMC Hummer EV — achieving over 300 kW peak power and raising state-of-charge from 1% to 53% in just 27 minutes (source: InsideEVs test).

Notably, Walmart does not outsource its software platform. Its charging management system was developed in-house by Walmart Global Tech, enabling charger connectivity, real-time status monitoring, and payment processing. It also pushes live data — including availability and pricing — to major navigation and charging platforms such as Apple Maps, Google Maps, PlugShare, ChargeHub, and Chargeway. User-facing features — including station search, session start/stop, payment, and real-time progress tracking — are deeply integrated into the Walmart app. No separate charging app is required. Walmart+ members receive discounted charging rates.

Adam Happel, General Manager of Walmart's Retail EV Charging Business, emphasized: "When customers pull into a Walmart charging station, we want the experience to feel as reliable and effortless as shopping. Hitting 100 sites is a key milestone — but our core mission remains building a trusted network that delivers on its promise, every time."

Walmart previously committed to installing EV charging infrastructure across thousands of Walmart and Sam's Club locations by 2030. With over 5,200 U.S. stores — and the geographic advantage that 90% of Americans live within 10 miles of a Walmart — the network has strong potential to become one of the largest third-party fast-charging infrastructures in the country.
