<h3>Boxing Clever</h3>
<p><em>Peter Donaldson investigates a containerised system that can charge multiple vehicles and doesn’t need a grid connection</em></p>
<p>Until the electric power grid is able to support fast charging for EVs everywhere, there is likely to always be a market for something like Fellten’s Charge Qube – a containerised system that stores energy in repurposed battery packs and can charge multiple vehicles simultaneously, with or without a connection to the grid.</p>
<h5>Key Applications</h5>
<p>The system is initially intended for sites that need charging capacity and either don’t yet have planning permission for permanent installations or they don’t need it. Fleet depots transitioning to EVs may fall into the first category.</p>
<p>Building contractors wanting to replace diesel generators on site to charge electrified off-highway vehicles and other equipment, and open-air festival and show venues are likely to fall into the second category.</p>
<h5>Design and Delivery</h5>
<p>Weighing at least 3.5 t, depending on the number of battery packs installed, the system is designed to be delivered to the site on a flat-bed truck with an integral crane, and it can be positioned on any piece of level, dry ground firm enough to take its weight.</p>
<p>Once delivered, it can be put into service in under two hours. Today, the maximum capacity is 450 kWh with six 75 kWh battery packs in a 10 ft container format; 20 ft container options are being finalized with capacity up to 900 kWh.</p>
<h3>Charging Capabilities</h3>
<p>For fleet operators and businesses that need overnight charging for multiple vehicles, the system can be equipped with a pair of Type 2 AC chargers on Qube itself, and two each on five satellite ‘pavilions’.</p>
<h5>Capacity and Speed</h5>
<p>It can charge up to 12 vehicles at the same time at up to 7 kW per port. There is also an integral, 22 kW charger for rapid top-ups during the day. The smart charging software prioritizes overnight charging and recharges the onboard battery pack in 6.5 hours.</p>
<p>Qubes equipped with a pair of 150 kW Combined Charging System (CCS) fast chargers are aimed at businesses and public charging networks that need rapid charging capabilities.</p>
<h5>Operational Flexibility</h5>
<p>If needed for only a short period of time, during which it will not need recharging, Qube can operate as a standalone system. However, it can also be connected to the grid or any kind of trickle-charging device, including diesel or multi-fuel generators, solar panels, and wind turbines. Multiple Qubes can be daisy-chained together.</p>

<h3>Second-Life Packs and Containers</h3>
<p>An important part of Fellten’s business model for Qube is the use of second-life components, which cut manufacturing costs and reduce the carbon footprint, says CEO and co-founder Chris Hazell.</p>
<h5>Cost Effectiveness</h5>
<p>“The fact that we are using second-life components but others are not makes it more cost-effective for us to build, and allows us to sell it for less. There’s also a major benefit for bigger companies because the environmental impact is lower and the carbon offset is a lot better,” he says.</p>
<h5>Battery Selection</h5>
<p>The battery packs used in Qube are not those that have degraded to 80% of their original capacity. Fellten also converts classic cars to electric power and has years of experience dismantling and reworking battery packs from various manufacturers.</p>
<h3>Power Electronics</h3>
<p>At the heart of the AC charging system is an off-the-shelf inverter that was the subject of a long and thorough search, enabling Fellten to proceed with Qube’s development.</p>
<h5>Inverter and Efficiency</h5>
<p>“We designed the Charge Qube five years ago, but then found we had to buy so much power electronics that it was never going to be financially viable. Now we can use complete OEM battery packs without modifications,” says Hazell.</p>
<h3>Battery Management</h3>
<p>Qube’s main control computer, based on a Raspberry Pi, oversees the battery packs along with the rest of the subsystems. Custom software has been developed to work with the battery packs while retaining OEM safety systems.</p>
<h3>Fire Safety</h3>
<p>To deal with electrical fires, Qube has a CO2 or powder extinguisher triggered by temperature sensors. The thermal management system monitors each pack individually and automatically shuts down systems if a pack overheats.</p>
<h3>Connectivity and Monitoring</h3>
<p>Fellten plans to monitor its Qube fleet through the cloud, fitting each unit with communication systems such as wi-fi, cellular, or satellite depending on data requirements.</p>
