UK startup Allye builds 400 kW fast charger from spent EV batteries to avoid grid upgrades
By Eve
London-based Allye has reused spent electric vehicle batteries to build a 400 kW fast charger, according to the report. The approach lets sites offer fast charging on their existing electricity supply, without the cost of a grid connection upgrade. Allye argues that charging sites lack power rather than energy, and that limited grid capacity is the common hurdle slowing large fleet charging rollouts.
Why it matters
Grid connection cost and delay are a major barrier to fast charging projects, so battery buffered chargers could widen the list of viable sites for CPOs and fleet operators. Procurement teams may want to assess this as an alternative to waiting for a connection upgrade.

Openreach and Allstar expand home, public and shared depot charging for 7,000 electric vans
Openreach has partnered with EV payment specialist Allstar to widen charging access for its 7,000-strong electric van fleet, where around one in three engineers cannot charge at home. Allstar Homecharge pays work-related home charging costs directly to drivers' energy suppliers, while public charging is being concentrated through fewer strategic charge point operators and Allstar Co-Pilot helps engineers find approved locations. The partnership is also developing commercial and shared depot access through partners including First Charge and Voltempo, offering larger bays, high-speed charging and bookable slots payable with existing cards such as Allstar Chargepass.
Why it matters
A large UK fleet is consolidating public charging onto fewer operators and seeking depot sites with larger bays and bookable high-speed charging, which signals what fleet buyers will favour in procurement. Operators serving commercial vehicles with card-based payment and booking have a clear route into this demand.
TellusPower and Zūm deploy bidirectional chargers for US electric school bus fleets
TellusPower is supplying bidirectional chargers to transportation-as-a-service startup Zūm, which is credited with deploying the first fully electric school bus fleet in the US, a 75-strong fleet in Oakland Unified School District for the 2024 to 25 school year. A more recent project with San Francisco Unified School District uses the same hardware, which Zūm white-labels. TellusPower CEO Mike Calise told EV Infrastructure News that the chargers act as a "power router", linking idle bus batteries with the grid, buildings and battery storage for up to 5MW of theoretical cumulative capacity.
Why it matters
Fleets with fixed duty cycles, such as school buses and refuse trucks, are being positioned as dispatchable energy assets, which could change how depots are specified and how bidirectional hardware is procured. The white-label arrangement also shows hardware vendors reaching the market through fleet service providers rather than selling direct.
Moto reports 96% customer satisfaction across its motorway services network
Independent research found satisfaction across Moto's network reached 96%, up from 94% in 2023 and 93% in 2022, while 95% of all visitors to motorway services were fairly or very satisfied. Five Moto sites (Rugby, Sawtry, Kinross, Pease Pottage and Donington Park) scored 99%, and the lowest scoring sites reached 90%. Moto CEO Ken McMeikan said the company has invested more than £260 million in its services over the last five to six years.
Why it matters
Motorway service areas are key host locations for rapid and ultra rapid charging, and sustained operator investment in site quality shapes the dwell experience that charge point operators rely on. The figures give procurement teams a benchmark when assessing host partners, though the excerpt provided does not detail the charging element.
