In this case study article, we learn how standardised bespoke EV switchboards from Proteus have been utilised in the rollout of EV charging infrastructure for some of the UK’s retail parks.
Did you know that Proteus offers a large range of custom designed, bespoke LV switchboards, panelboards, distribution boards and consumer units?
This service has been evidenced in a recent project where Proteus has designed and manufactured a bespoke EV switchboard for a client to roll out across multiple retail park locations across the UK.
Working closely with customers ensures that they achieve the exact switchgear arrangement that their installations require.
Specific requirements
For this particular project the customer’s requirement was to feed 5 x 100 kW EV fast chargers and provide protection against an open PEN conductor, as the supply was derived from a shared transformer with PME earthing. Additionally, the mains supply was to be rated at 1,000 A.
The challenge for the Proteus Design & Quotations department was to standardise a design to suit these requirements as closely as possible, providing a suitable solution for a 20+ site EV charger roll out installation.
A bespoke board was designed at Proteus’ Telford-based operation and fitted with 2 x 1,000 A, 3 pole, motor operated MCCBs, controlled by a matt:e O-PEN monitor to provide open PEN protection.
The monitor works in conjunction with an interlocking relay system which ensures the correct opening and closing sequence of the 1,000 A MCCBs. These MCCBs switch the supply to the distribution busbars which supplies 5 x Proteus 200 A, 4 pole, thermal/mag MCCBs for the EVC supplies.
This design was detailed in technical drawings for the client to see and approve before the manufacturing commenced. Once approved, the design was processed through the various operations within the factory, taking the materials from their raw formats to the designed and tested PRO2000 that is delivered to site.
Further challenges
There was also a width restriction at the installation location, which with the flexibility of the PRO2000 panel system and the in-house design expertise, Proteus was able to easily accommodate.
To provide further protection, the panel was also fitted with Type 2 mains surge protection and thermostatically controlled, anti-condensation heaters.
RCBOs were fitted for local services and supply to a panel mounted 3 pin socket, all designed and assembled on- site before QC, testing and despatch.
All of this resulted in a once bespoke (but now standardised for the customer) floor standing panel, with incoming cables top entry and EVC cables bottom exit.
