Chalmers researchers model reconfigurable EV battery packs that bypass weak cells
By Eve
Researchers at Chalmers University of Technology in Sweden, working with PHINIA and Scania, have published a study in Nature Communications assessing reconfigurable battery packs that use switches and control systems to bypass weak cells. The modelling shows that controlling each cell separately could extend battery life by over 20% in high voltage vehicles such as electric trucks and long range cars, though in practice groups of cells are more likely to be controlled together. The study examined an 80 kWh battery in a car driven 12,000 km per year.
Why it matters
Extended battery life directly reduces total cost of ownership for fleet operators and could influence procurement decisions for electric trucks and long range vehicles. The technology, developed with commercial partners PHINIA and Scania, may shape future battery pack specifications and maintenance strategies in the charging infrastructure ecosystem.

Zeekr unveils 9X plug-in hybrid SUV in Europe with 910bhp and 9.5 minute fast charge
Chinese manufacturer Zeekr launched its 9X six-seater SUV at the 2026 Paris Motor Show, priced from €119,500 (around £100,900). The 2.9-tonne vehicle combines a 2.0-litre turbocharged engine with a 55.1kWh battery and 900V electrical system, delivering almost 910bhp and a 111-mile electric-only range. The 900V architecture enables 10% to 80% charging in 9.5 minutes.
Why it matters
The 9X's 900V fast charging capability and premium positioning signal intensifying competition in the high-end electrified SUV segment, potentially driving demand for ultra-rapid charging infrastructure at luxury destinations. The vehicle's sub-10 minute charging time sets a new benchmark that may influence CPO investment decisions for premium charging networks across Europe.
Nottingham City Transport deploys first six electric double-deckers with £4.5m EMCCA backing
Nottingham City Transport has taken delivery of six Wrightbus StreetDeck Electroliner Gen 2.0 electric double-deckers, its first zero emission double-deck buses, following completion of a 62 vehicle electric single-deck rollout. The Mayor of the East Midlands and East Midlands Combined County Authority contributed £4.5m towards the double-deckers, which feature a 442kWh powertrain and up to 275 miles of range. Energy partner VEV has completed overnight charging infrastructure at NCT's Parliament Street garage, with further electric double-deckers due before Christmas to bring the zero emission fleet to 93 vehicles, representing about one-third of the total fleet.
Why it matters
The deployment demonstrates scaled depot charging infrastructure delivery by VEV and signals continued public procurement momentum for electric double-deck buses in UK cities, with EMCCA funding enabling fleet electrification beyond initial single-deck phases. The 442kWh battery specification and overnight charging model provide a reference point for operators planning similar double-deck conversions.
Hanoi deploys 53 VinFast electric buses on four routes as part of 2030 full fleet conversion target
Hanoi public transport operator Transerco introduced 53 new VinFast electric buses on routes 22A, 22B, 30 and 50 on 5 and 6 October 2026, replacing diesel vehicles. The deployment comprises 28 VinFast Green Bus vehicles and 25 VinFast EB8 buses, all manufactured in 2026 with 60 passenger capacity. Transerco aims to increase green converted vehicles to more than 51% of its fleet by end 2026, supporting Hanoi's municipal programme to replace all petrol and diesel public buses with electric and green energy vehicles by 2030.
Why it matters
The rollout demonstrates accelerating municipal fleet electrification in Southeast Asia and signals sustained procurement demand for electric bus manufacturers and charging infrastructure providers in Vietnam's capital. Transerco's 51% green fleet target by end 2026 and the 2030 full conversion deadline create a defined timeline for CPOs and equipment suppliers to secure contracts in Hanoi's public transport network.
