Ionna tops JD Power public charging satisfaction study, ahead of Tesla Supercharger network
By Eve
JD Power's latest study found Ionna, the charging network backed by eight automakers including GM, Honda and Stellantis, scored highest for overall satisfaction among national DC fast charging networks in the United States, surpassing Tesla's Supercharger network. The study reported the lowest rate of visits where drivers could not charge since tracking began, with improvements in satisfaction around charging costs and safety. Ionna offers chargers delivering up to 400 kW and does not require a dedicated app or subscription, with locations typically featuring food, drink and restroom facilities.
Why it matters
The findings signal that non-Tesla networks are closing the reliability and user experience gap, potentially influencing procurement decisions for CPOs evaluating which hardware and network partnerships deliver the highest customer satisfaction. Ionna's app-free model and amenity-rich sites may set a new benchmark for site design and operational standards in the competitive DC fast charging market.

BYD workforce hits 1.02 million, exceeding Toyota, GM, Ford and Tesla combined
BYD now employs more than 1.02 million people, including up to 120,000 R&D engineers, chairman Wang Chuanfu told the China Society of Automotive Engineers' 33rd annual conference on Wednesday. The Chinese automaker added roughly 150,000 staff in 10 months despite falling vehicle sales, bringing its total above the combined headcount of Toyota, GM, Ford and Tesla. Around 960,000 work in China and 60,000 abroad, with R&D focused on battery cells, motors, electronic controls and semiconductors.
Why it matters
BYD's vertical integration strategy, keeping batteries, chips and motors in house, underpins its scale and signals intensifying competition for EV supply chain talent and manufacturing capacity. The workforce expansion, even as sales dip, suggests the company is investing heavily in R&D and production infrastructure that could reshape global EV and charging component markets.
Ford casts 5,000 unicastings for Fathom EV truck in Tesla style shift
Ford has produced more than 5,000 large aluminium unicastings for its Fathom electric pickup, due in 2027 at $28,350, with each truck using two castings that replace 146 individual parts. The castings are made at Ford's Shelbyville Technical Center and shipped to Louisville Assembly Plant for testing, following the manufacturing approach Tesla introduced with its Giga Press six years ago. Ford is working on cutting cycle time and designing the castings for modular repairability, addressing the repair cost concerns that have made other automakers hesitant about larger cast parts.
Why it matters
The shift to unicasting signals a major change in EV manufacturing that could reshape supply chains and reduce part counts, potentially affecting procurement strategies for assembly tooling, casting equipment and repair infrastructure. Ford's focus on modular repairability may also influence how fleet operators and charging site developers plan for vehicle servicing and downtime at depot charging locations.
Solar powered EV charging in Andhra Pradesh still at an early stage despite favourable conditions
A report on Nellore says Andhra Pradesh has abundant sunshine, a growing renewable energy ecosystem and rising interest in electric mobility, but solar powered charging remains nascent. Stations use rooftop or ground mounted solar panels with Battery Energy Storage Systems (BESS) to smooth fluctuations, drawing from the grid only when necessary. The article notes that public charging infrastructure in the state remains sporadic despite growing EV sales and strong government backing, and that Convergence Energy Services Ltd. (CESL), a subsidiary of Energy Efficiency Services Ltd. (EESL), was the first to deploy an integrated solar powered charging station in India.
Why it matters
Lower electricity costs at solar and BESS equipped sites could let charge point operators pass savings on to drivers, which makes Andhra Pradesh a potential market for integrated solar plus storage charging projects. The patchy public network, particularly for intercity travel, points to unmet demand for developers and funders.
