- Ayvens customers will gain access to Fellten’s containerised Charge Qube battery and charging systems.
- The equipment can supply rapid charging from stored electricity, helping fleets manage sites with restricted connection capacity.
- Commercial value depends on vehicle schedules, daily energy needs and the time available to recharge the battery.
Ayvens has partnered with British battery storage company Fellten to offer mobile EV charging to UK fleets, targeting businesses whose electrification plans face constraints from site power or permanent infrastructure.
The arrangement gives Ayvens customers access to Charge Qube, a battery energy storage system with integrated high-power charging. The equipment stores electricity and supplies rapid DC charging when vehicles need it, allowing charging demand to be managed around an existing site supply.
The companies are positioning the system for fleets with complex or changing requirements, including temporary and remote locations where conventional installations may be difficult.
“Access to power is becoming one of the biggest practical challenges facing fleet electrification,” Fellten general manager Mike Ellenthorpe said, as reported by FleetPoint.
Fellten’s own product information describes a range from 160kWh to 1MWh and claims deployment in under two hours. Those statements concern the equipment’s capabilities; they should not be read as a guarantee that every customer site can complete all preparations within that period.
Stored energy can bridge short charging peaks
The operating principle addresses a common mismatch between the rate at which a site can take electricity and the rate at which vehicles need to charge. A battery can accumulate energy over a longer period, then discharge it quickly during a concentrated charging window.
That can make sense where vehicles return in groups, require a rapid turnaround or use premises that do not justify a permanent installation. Mobility also creates the possibility of relocating charging equipment when a contract or operating base changes.
However, battery capacity and charging power describe different things. A high-power charger can deliver electricity quickly, while the battery’s usable energy determines how much charging it can provide before replenishment becomes necessary.
For illustration, a fleet requiring 500kWh each day must obtain at least that much electricity from its supply source, with additional energy needed to cover losses. Storage can alter when the electricity is taken and delivered, but cannot remove the daily requirement.
The product specifications show why configuration matters. Fellten lists the compact CQ160 with 160kWh of storage and battery recharge power of up to 40kW. Its larger CQ450 offers a different combination of storage, input requirements and charging equipment. Customers will need specifications for the actual system proposed rather than a single headline figure for the range.
Fleet economics extend beyond installation speed
For operators, the relevant comparison is the total cost of completing the transport task. That includes vehicle utilisation, electricity purchases and equipment charges, together with any reduction in public charging or operational downtime.
A temporary system could be attractive if it allows vehicles already ordered to enter service sooner. It may be less suitable where an intensive fleet requires more electricity each day than the site can supply, even with charging spread across available hours.
Environmental performance also depends on the electricity source and how the system operates. Battery charging has no exhaust emissions at the point of use, but that does not establish zero emissions across the energy supply chain.
The partnership’s significance lies in adding another infrastructure option to fleet procurement. Evidence of its wider impact will come from customer deployments, operating costs and vehicle availability. For businesses assessing the offer now, a measured site-energy assessment will be more useful than deployment-speed claims alone.
