How much energy does a Chargebox consume?

sustainable energy saving methods for companies to advocate like a wind farm

We get asked this question frequently because decision-makers are keen to understand the energy cost of operating a charging service and the sustainability of our products. With recent energy price hikes, it’s an important consideration when planning which type of charging service to install.

The good news is that even a heavily used ChargeBox isn’t going to make much of a difference to your energy bills. This is down to two key factors – first, we’ve chosen very low-power components to keep ChargeBox operational and managed, which means most of the energy used is actually to charge devices. The second factor is that charging a device – even a tablet or laptop – requires surprisingly little energy compared to activities such as boiling a kettle. 

Remember also that providing a charging service isn’t necessarily increasing your electricity consumption. For example, if sockets are available to visitors, passengers, customers, staff, etc., they will charge their devices ad-hoc. So, ChargeBox is replacing this usage with a highly efficient and safely managed charging infrastructure. This can also lead to a reduced requirement to provide power sockets with reduced installation, repair, and management costs, resulting in reduced capital and operating expenditure.

Depending on the product, a single Chargebox uses just one 13A socket to power between 3 and 8 simultaneous charges. Multiple units can even use the same single socket if placed close together.  So it’s an energy win-win! 

Energy usage of ChargeBox Vs Other electrical items

Our largest ChargeBox model is our FAST6 (6-locker) charging station for fast-charging phones and devices. Based on 100 uses daily of 20 minutes average charge, with an average power of 20W – and allowing for the large advertising screen on the unit, here are the following comparisons:

  1. Boiling a kettle just 5 times in one day consumes more energy and creates more emissions than the FAST6 does in a complete day of operation. 
  2. The electricity used to charge a typical large EV to 100% just ONCE consumes more electricity than 73 ChargeBox FAST6’s in high usage – equivalent to charging 7,300 devices!
  3. Having just 10 x 10W LED lights (the most efficient ones) on in your office consumes TWICE as much electricity daily as a ChargeBox FAST6 charging 100 devices.
  4. The average UK driver emits more CO2 in a day than 24 x ChargeBox FAST6 units charging 2,400 devices.
  5. A single high-power ElectricVehicle supercharger (e.g. at 150kW) uses more electricity in just 21 days than our 300-station UK fleet in a year, which can easily charge up to 5 million devices to 40% battery.

With customers increasingly dependent on their devices, and the reducing dependence on carbon-intensive activities this brings, it’s time for companies to unleash the power of offering a world-class charging service. 

Device charging should be an essential part of the customer experience rather than encouraging ad-hoc plug socket hoarding!
