The evec vecBOLT VEC40DC-DG is a 40kW dual-gun DC rapid charger for commercial sites that want one cabinet to serve two vehicles and reduce waiting at busy bays.

Some locations are busy enough that a single rapid bay quickly becomes a bottleneck, but not yet busy enough to justify multiple rapid cabinets. VEC40DC-DG is designed for that middle ground. It is a 40kW DC charger with dual charging capability, allowing one unit to serve two EVs by splitting its output when both guns are in use. That makes it useful for retail destinations, leisure venues, public car parks, mixed-use developments and fleet sites where dwell times are short enough to need rapid charging, but budgets and site footprints still need careful control. The key commercial point is not just that it charges fast. It helps a site handle more sessions from one cabinet position without immediately doubling charger hardware.

• Best suited to: higher-demand commercial sites needing two-vehicle service from one cabinet

Two vehicles from one 40kW DC charger

The main reason to choose VEC40DC-DG is throughput. A dual-gun charger can keep a site moving when one rapid bay would otherwise create a queue or leave one side of a paired parking area underused. evec states that the charger can split its power to charge two EVs simultaneously, which is exactly the behaviour many growing sites need. It does not try to replace a larger multi-charger rapid hub. Instead, it gives one cabinet the ability to cover two vehicles and smooth out the user experience. For operators, that can be a smarter first upgrade than simply moving to a higher power single-output unit if the bigger issue is waiting time rather than the speed of one session alone.

Shared rapid charging for growing sites

Dual-gun DC charging is especially relevant when the site is moving from occasional EV use to regular demand. A retail park with steady weekend traffic, a leisure venue with repeat afternoon peaks, or a workplace visitor bay that fills at certain times can all benefit from one charger serving two cars. In those cases, the charger is not only a power device. It is a queue-management tool. More drivers can plug in during the same period, which helps the site appear more dependable and avoids one user monopolising the entire rapid offering. For businesses comparing options in commercial EV chargers, that operational benefit can matter just as much as the technical specification.

RFID, contactless payment and OCPP control

A dual-gun rapid charger only works well when access, pricing and reporting are under control. VEC40DC-DG supports OCPP 1.6 JSON, RFID, plug and play, app-led charging and optional Payter payment hardware. That mix allows the charger to be used in public, semi-public or controlled private settings. An operator can restrict access, monetise sessions, or connect the charger into a backend platform for reporting and support. That is important because two-gun charging usually means more users and more varied charging behaviour. What feels manageable on a single private bay can become messy on a dual public-facing cabinet. The control options here help the charger act like a managed commercial asset rather than a simple power outlet.

4G, Wi-Fi and Ethernet connectivity

Commercial rapid chargers are ongoing service assets, so connectivity matters after installation just as much as it does on day one. evec lists 4G, Wi-Fi and Ethernet communications for this model together with over-the-air updates. That gives the charger flexibility across a wide range of site conditions. A business park may prefer Ethernet. A more exposed or remote location may favour 4G. A site with stable local networking may use Wi-Fi. The practical benefit is that the charger is not boxed into one commissioning route, which can make rollout easier across different premises. For operators managing more than one site, communications flexibility also supports a more consistent charging offer across locations with very different infrastructure.

IP54 build, Mode 4 and mounting choices

VEC40DC-DG is built for outdoor commercial use with IP54 weather protection, CE/UKCA certification, working temperatures from -20°C to 55°C and a net weight of 75kg. evec lists wall mounting as standard, with a floor-mounted option available via a charger base. That helps specifiers position the charger in a way that makes sense for bay layout, traffic movement and cable approach. Mode 4 charging confirms its role as a true DC rapid charger rather than a higher-output AC point. These physical details matter because the dual-gun format is often chosen specifically to serve busier sites. A charger used in that way needs not just electrical capability, but a cabinet and installation approach that can cope with repeated public-facing use.

Why one dual-gun cabinet can beat two singles

On the right site, one dual-gun rapid charger can be a more sensible early investment than two separate cabinets. It can reduce waiting, improve use of paired bays and hold down hardware count, which in turn can help with visual impact, installation space and overall project cost. That does not mean it replaces larger-scale charging infrastructure everywhere. It means it can be a disciplined next step for sites whose demand is growing but still concentrated in one area. The dual-gun format is especially attractive where the operator wants more charging coverage without turning the site into a charger yard. In that sense, VEC40DC-DG is about efficient site planning as much as it is about rapid charging power.

Protection, payments and bay planning

Because this charger is likely to serve more drivers than a single-gun equivalent, bay planning matters. Payment setup, RFID rules, protective barriers and site signage all have a bigger impact once two vehicles can be connected to the same cabinet. Optional Payter payment hardware gives a route to direct user payment, while careful physical planning helps keep the charger readable and resilient in service. On exposed or public-facing bays, products such as chargepoint protectors and related industrial signs often deserve attention at the same time as the charger itself. Coordinating these details alongside EV charger installation usually produces a cleaner result than treating the charger as the only part of the job that matters.

Choosing dual-gun and single-gun vecBOLT models

Choose VEC40DC-DG when the site needs one cabinet to cover two vehicles or when queue reduction is part of the business case. Choose the single-gun version when one rapid bay is enough and a simpler one-vehicle-at-a-time operating model suits the location. In other words, the dual-gun model is the better fit for growing demand, visitor peaks and shared public-facing sites that need broader service from one charger position. It is not automatically the right choice for every rapid-charging project, but it is the logical step where one cabinet needs to do more work and serve more users without a full multi-cabinet build.
