Electric car industry growth: CEO of Tata Elxsi emphasizes importance of fast charging infrastructure
Table of Contents
The sustainable growth of the electric vehicle (EV) industry and the achievement of Europe’s ambitious climate goals are directly dependent on the rapid development of widely available charging infrastructure. As Tata Elxsi CEO Manoj Raghavan emphasized, without adequate expansion of the charging network, it will become increasingly difficult to continue the current pace of development. His comments come from the mouth of the head of a global design and engineering company that works closely with India’s space research organization and is actively working on solutions for the auto industry, including car manufacturer Jaguar Land Rover, owned by the Tata group.
Cost and availability of European charging points: Key obstacles
Raghavan points out that the main factors hindering Europeans from switching to electric vehicles are both the high price of EVs themselves and the availability of charging stations. There are currently estimated to be around one million public charging points in Europe, mainly concentrated in major cities in the Netherlands, Germany and France. But to really sustain rapid growth in the EV industry, a significantly higher number is needed. Manoj Raghavan estimates that Europe needs at least 3.5 million public charging points, with as many as 8 million.
Fast charging stations: Need and current situation
But the problem is not only in the total number of charging points. “The availability of fast charging stations is also an issue,” added Raghavan. There is currently about one charging point per EV in Europe, which he says is far too few. For EVs to become a convenient and attractive choice for a wide range of people, this ratio should be around 1:2 or 1:3. More critically, it is necessary to ensure that 60-70% of all charging stations are fast charging stations, but currently only about 13% of stations provide such capacity. Raghavan warns, “Having more EVs on the road, especially during peak hours or the holiday season when everyone is on the road and charging stations are full, doesn’t make for a good user experience. People will soon start longing for their internal combustion engines.”
Battery innovation and sustainability
In addition to the charging infrastructure, the future of the industry is also influenced by the development of battery technology. Although issues related to EV battery fire safety, failure, and cost have significantly decreased, the cost of raw materials and the security of their supply remain a pressing issue. Manoj Raghavan expressed hope for the use of alternative materials, such as silicon, sand or sodium, which are available in larger quantities and would reduce the need to mine lithium and other rare earth metals. He predicts that in the next 5-10 years, new battery materials will allow users to travel 1000 km after only 5 minutes of charging. Also, the need to increase the recycling capacities of existing generation EV batteries is emphasized.
Digital solutions for battery management
Tata Elxsi has developed innovative solutions to address these challenges. The “battery passport” they created allows companies to track materials throughout their life cycle – from extraction to recycling. This solution is especially important because manufacturers, even as they bring more and more EV variants to market, will need to understand and manage the many different battery systems. In addition to the “battery passport”, a “digital twin” solution is also offered, which allows monitoring the performance of each individual battery, even down to the level of individual cells. These tools and techniques promote the recycling and reuse of lithium, reducing the burden on the planet.
