Charier, a major player in public works, is pursuing an ambitious CSR strategy. One of the pillars of this strategy is to encourage employees to adopt electric vehicles.

To support this transition, Charier has decided to install 16 charging points and an Eiko power cube in the car park at its head office in Couëron.

Already equipped with 8 charging points, the company wanted to increase its capacity in response to the rapid electrification of its vehicle fleet. However, a conventional installation would have required 7 times more power.

The challenges of recharging for businesses: the Charier case study

As part of a strong CSR policy, introducing recharging in the workplace is a major challenge on several levels.

Save on energy bills with second-life batteries

Eiko’s built-in second-life batteries store energy during off-peak hours and redistribute it during peak hours. This innovative French solution offers a number of advantages:

  • Lower electricity bills: The company buys energy when it is cheaper and uses it when it is more expensive, resulting in substantial savings.
  • Contributing to the energy transition: Using second-life batteries reduces the carbon footprint of their manufacture, contributing to even more sustainable electric mobility.

Optimising recharging with an intelligent solution

Mob-Energy’s approach to recharging aims to maximise the use of resources such as power. Responding to Charier’s needs was a two-stage process:

  • Identify the energy needs of the fleet of vehicles in the company car park, so as not to oversize the electrical infrastructure and lead to under-utilisation of the installed power.
  • This sizing of requirements highlighted the benefits of the Eiko solution and its battery energy storage. With a grid connection of just 30 kW, Eiko fulfils the same mission as traditional charging points, which would have required the allocation of almost 200 kW of power in total.

Producing energy using photovoltaic panels

The solar panels on the Charier site enable this passive building to produce the energy it consumes. To further increase self-consumption of the energy produced by these solar panels, a project to connect them to Eiko’s batteries is under way. By storing surplus production before redistributing it to electric vehicles, Eiko will enable Charier to make even greater savings on its energy bill while contributing to the company’s CSR objectives.

Eiko is the intelligent recharging solution for our electric vehicles.
It’s also a storage solution that allows us to lower the cost of our energy consumption (thanks to off-peak hours).
We are equipping our head office car park with Eiko, 2 storage batteries for 80kWh, and 16 charge points.
We were won over by the intelligence and optimisation of the system, which means that with just 30 kW of power allocated, we can fulfil the same mission as with a 200 kW connection for traditional charging points.
The support provided by the Mob-Energy teams also enabled us to better understand the energy needs of our fleet in a car park like ours, and to avoid installing power that would never have been necessary in reality.
By relying on Mob-Energy, we are also pursuing our CSR commitment, through the use of second-life batteries and our Made in France purchasing policy.
