Electric Vehicle Charging is the provision of electricity to recharge the batteries of hybrid or electric vehicles.
Forecasts for 2030 estimate that there will be more than 145 million electric vehicles worldwide. This trend is reinforced by the decision of the European Union to put an end to the sales of new thermal cars from 2035.
The democratization of electric mobility raises new challenges in terms of the deployment of recharging infrastructures and the optimization of recharging processes.
After unidirectional charging (V1G), one of the main lines of development is now focused on “Vehicle-to-Grid” (V2G) technology. This new bi-directional charge system redistributes the energy stored in the electric vehicle battery to the grid.
France has more than 1.5 million electric and plug-in hybrid vehicles by the end of 2023, according to AVERE. Electric car sales have increased 47% over 2022 (source: PFA), demonstrating commitments to electric mobility and energy transition.
To reach the challenges of charging electric vehicles, the country had 118,009 public electric charging stations as of December 31, 2023 (source: AVERE).
The government supports the deployment of electric mobility through multiple purchasing aids (electrical bonuses, conversion bonuses, social leasing, charging station subsidies, etc.) A total of €1.5 billion to reach the 100% electric car target by 2035.
“In order to meet demand and the rise in electric vehicles, the challenge now is to deploy more charging infrastructures as well as improve their operation and interoperability.”
The challenge is to continue deploying public charging station networks in both urban and rural areas. Particular attention needs to be paid to high-power charging on expressways, as well as to the equipment of collective residential buildings.
Charging stations will also be increasingly faster, to optimize and reduce charging times for electric and hybrid vehicles.
Interoperability between different types of recharging stations and electric vehicles will help ensure that drivers can easily use different recharging infrastructures, whatever their vehicle model.
Some CES 2024 exhibitors have revealed some projects and ongoing research such as wireless charging through a smart robot, or charging vehicles by induction. The power and speed of recharging are also a subject under development, with the aim of reducing the recharging time. There are also workstreams to develop very high-power recharging to enable trucks to access electric mobility. “
Another focus of innovation is to develop Vehicle-To-Grid, a technology that enables electric vehicles to supply electricity to the grid. Using bi-directional charging and discharging systems, Vehicles can inject electricity stored in their batteries into the grid during periods of high demand or when electricity is more expensive.
The V2G offers the possibility to optimize the use of energy resources, strengthen the stability of the grid, contribute to the use of decarbonized electricity and reduce Co2 emissions.
Software République, in partnership with IoTecha Corp, has launched Mobilize Powerbox®: the beginning of the realization of V2G technology in France.
LACROIX manufactures this bidirectional charging station in the French Symbiose electronic assembly plant.
The Mobilize Powerbox® communicates with the car and the “cloud” to recharge the battery or send electricity back to the grid based on the need to recharge the battery, domestic needs and incentives from the energy market and the public grid. In short, it calculates the right time to recharge the car’s battery when the energy market prices are at their lowest. The rest of the time, the vehicle’s battery is used to power the energy consumed by the home.
LACROIX provides its manufacturing know-how to help players produce these charging stations in France. A number of charging stations, the most modern of which will be manufactured in our factories. We work on electric charging stations, but we also have equivalent activities on other forms of low-carbon mobility. “
