5 Things to Know About EV Charging Stations


As the transition to electric vehicles (EVs) accelerates, charging infrastructure is increasing, becoming essential components of our cities. Although their presence is becoming increasingly well known, many of their characteristics and implications remain little explored by the general public. This article delves into five surprising and often overlooked aspects of electric charging stations.

1. Fast Charging Technologies: More than a Question of Power

The ability to quickly charge an electric vehicle lies not simply in the amount of electricity transmitted, but also in how it is managed. Fast Ev chargers use sophisticated power converters that dynamically adjust voltage and current based on battery condition.

These systems are equipped with advanced sensors and software that monitor crucial parameters like battery temperature, charge rate and structural integrity. This monitoring not only allows for efficient but also secure charging, extending the life of batteries by avoiding overcharging and damage from excessive heat.

  • Average fast charge time (0-80%) : 30 minutes

  • Typical fast charging power : 50 kW to 350 kW

  • Reduced battery life by frequent fast charging : Up to 20%

2. Sustainability of Materials: An Environmental Challenge

EV chargers are often built with materials such as copper for cables and aluminum for housings, the extraction and processing of which pose significant ecological challenges. Extraction of these minerals can lead to deforestation, water pollution and other environmental impacts.

Additionally, the manufacturing process for electrical components can consume large amounts of energy and generate hazardous waste. To meet these challenges, research is turning to more sustainable alternative materials or improved recycling methods that minimize the ecological footprint of the production of charging stations.

3. Symbiosis with Renewable Energy

The integration of charging stations with renewable energy sources is a promising step forward to reduce the carbon footprint of EV charging. Photovoltaic installations on the roofs of charging stations, or nearby mini wind turbines, make it possible to produce clean electricity directly used for charging.

This approach not only reduces reliance on fossil fuels but also allows charging stations to operate autonomously during main grid outages, strengthening local energy resilience.

  • Percentage of charging stations incorporating solar panels : 15%

  • Reduction of CO2 emissions with solar energy : 50% per terminal

  • Power generation capacity of a typical solar roof : 10 kW

4. Energy Storage Centers: Beyond Charging

Some modern EV chargers function as energy storage centers. They accumulate electricity during off-peak hours, often produced by renewable sources, and redistribute it during peaks in demand.

This feature helps stabilize the power grid by reducing load during periods of high consumption. It also presents potential for innovative business models where charger operators sell stored electricity, transforming charging stations into proactive players in the energy market.

  • Typical storage capacity of terminals : 100 kWh to 1 MWh

  • Percentage of terminals offering energy storage capacities : 5%

  • Reduction in energy costs thanks to storage : 15% to 30%

  • Lifespan of storage batteries : 10 to 15 years


EV chargers for electric vehicles embody a key technology in the energy transition towards cleaner mobility. However, they are more complex and multifunctional than they seem. By exploring these little-known aspects, we can better appreciate their potential and their importance in our near and distant future.
