Residential EV charging at scale
Problem Addressed
- The lack of reliable and affordable charging solutions
- System deliveries with larger power capacity requirements
- requiring more upstream infrastructure (cabling, substations etc)
Case Study
Residential development in Bow: Pod Point installed a Load Balancing Solution for an underground carpark.
Devon’s Road is a mixed use development comprising apartment blocks and individual plots, with a large underground car park in Bow, East London. In such developments a London-wide planning condition requires the installation of electric vehicle chargepoints in 20% of the development’s parking bays at build stage (“active” provision) and the provision of infrastructure for future installation of chargepoints in an additional 20% of the development’s parking bays (“passive” provision). In order to satisfy the condition there must be enough available power for both the active and passive provision. For Devon’s Road, the requirement equated to 23no active chargepoints, with passive provision for a further 23no chargepoints.
Challenges
- insufficient substation capacity to account for all 46no 7kW chargepoints and upgrading to allow for a further 150kVA was not feasible, logistically or financially
- Available supply to the underground car park was insufficient for the planned 23no chargepoints in that location
- Site underground location and the potential lack of a 3G or 4G signal
Solution
As well as providing chargepoints, systems and installation services for the Devon’s Road project, Pod Point also acted as consultant to the client; designing a bespoke solution and a phased implementation plan.
Result
23no wall mounted 7kW solo units were installed in the underground car park, utilising cable trays fit specifically for EV charging to run power and data cabling neatly at high-level, over a 50m stretch, and then down to each individual unit position. The cabling from the tray to each unit ran behind the wall, giving a visually appealing “Floating Pod” appearance at each chargepoint enabled parking bay.
Thanks to the Pod Point Load Balancing System, all 23no chargepoints in the underground car park have the infrastructure to be used simultaneously from just a 100A three phase supply, saving the client significant budget and protecting the site’s electrical infrastructure. The 7kW units have the capacity to deliver up to 30 miles of range per hour of charge, which the resident will pay for via their Pod Point smart phone app. The client manages this by allowing only residents of the development access to the chargepoints, and setting a tariff to cover the cost of electricity used. Pod Point handles the full billing process, rebating the client and leaving them without an ongoing administrative burden
