Cases & enclosures
EVs drive demand for
robust charging enclosures As e-mobility demand increases year-on-year, a corresponding requirement is placed on supporting infrastructure, primarily the charging point. Protecting the charging points against adverse weather or impact damage is vital to maintaining safe and reliable charging, which puts enclosures at centre stage. Here, Chris Lloyd, managing director at Spelsberg UK, explains the key drivers behind e-mobility enclosure design.

n 2020 more than 10 per cent of all UK car registrations comprised of electric vehicles (EV). The gathering pace of EV
sales is of little surprise and is set to increase; one reason being the closing proximity of the UK’s deadline on the ban of combustion engine car sales, brought forward from 2040 to 2035. Concerning public transport, between 2020
and 2024 the electric bus market is expected to grow at a rate of nearly 50 per cent. The e-mobility sector is of course also joined today by e-bicycles. In the Netherlands, albeit with a strong history of participation in cycling, over 50 per cent of all adult bikes sold in 2018 were electric. According to a recent report, it is predicted that by 2023 the number of e-bikes, including those privately owned and publicly shared, will reach over 300 million, a 50 per cent increase over 2019’s figures. The growth in EVs means a corresponding
requirement for growth in charging points. To meet demand, as of January the UK had over 30,000 publicly available electric vehicle charging points across nearly 14,000 locations.

Charging points include electrical distribution, the interface between the vehicle and the power grid, which is as crucial to an EV as its battery. To achieve safe, reliable charging whatever the conditions, a robust enclosure has to provide protection to the electrical distribution unit while ensuring safe operation to users and the wider electrical circuit. Working with leading car manufacturers,
Spelsberg developed bespoke enclosures to ensure safe, secure and easy to use vehicle charging, from domestic applications through to semi-public installations, such as car parks. Each project is characterised by a unique specification which depends upon the design of the power supply distribution circuit and components, and all meet the required standards, including VDE and UL. Spelsberg enclosures tailored for e-mobility
charging are designed to bespoke required dimensions for the location, which could range from a car park charging pillar to a distribution board for a garage or car port. Consideration of the installation’s location and the number of charging points is also combined with climatic
