EV charging infrastructure for autos is inadequate
In the last seven months as an autorickshaw driver, Pavithra Prakash has learnt some hard lessons about driving an electric vehicle. 'Once charged, my auto can run for 160 km and I make it a point not to cross 110 km,' says the 29-year-old mother, happy about the financial independence ushered in by her new job. She has 'range anxiety' whenever the three-wheeler crosses that mark as it is usually difficult to find an EV charging station nearby. Even if she were to charge at a public charging point, it would require her to wait for a few hours.
'Once I was left with charge for just 30 km and the vehicle started making alarming sounds, I panicked as my house is located near Red Hills and I just wanted the charge to be sufficient for me to reach home,' says the autorickshaw driver who charges the vehicle at her home.
Pavithra's husband, who has an auto running on compressed natural gas, encouraged her to opt for an electric vehicle for the ease it would offer the young driver who learnt driving skills from Association of Non-Traditional Employment for Women (ANEW) in Anna Nagar.
'On days when I get many rides I am forced to wind up by 2 p.m. as the vehicle does not have charge. I sometimes refuse long-distance trips fearing the situation that would manifest if I run out of charge,' says Pavithra.
Anxious if the battery will drain out, autorickshaw driver R. Shanthalakshmi only takes shorts trips in and around Palavakkam where she resides. 'When I purchased the vehicle from a showroom in Tambaram, they told me there are public charging stations I could use, but in the five months since I have been driving this vehicle I have not discovered even one, so I charge the vehicle every night at home,' says Shanthalakshmi, who is content earning ₹1000 to ₹1500 a day ferrying people. Her income as an autodriver is supplemented by earnings from petty shops she runs near her home.
Showrooms retailing three-wheelers say the demand for electric vehicles is noticeably greater than what it was last year. In March this year, Chief Minister M.K. Stalin handed over 50 electric autos to women members of urban self-help groups under the Environment and Climate Change Department to empower them to be financially independent while promoting sustainable mobility.
'Unlike public charging stations for two-and-four-wheelers, there is no such facility for autorickshaws. Some showrooms selling the vehicles make provision for charging outside their store,' says R. Ashwanth, manager, Rag Motors. He says there are two variants in three-wheelers: one has 125 - 150 km range and the other 200-250 km, a majority go in for the latter and are happy as their everyday travel is usually covered by that range.
Those in the industry say public charging infrastructure should keep pace with electric vehicle sales. Giving subsidy to vendors will also encourage establishment of more facilities.
No standardisation
Ragavendra Ravichandran, co-founder and chief operating officer, Plugzmart, agrees the charging infrastructure for three-wheelers is yet to pick up. The chargers currently used by electric autos have not been standardised.
'For electric four-wheelers, there is broad standardisation among major brands when it comes to charging interfaces. AC chargers typically use the Type 2 connector, and DC fast chargers commonly use the CCS2 (Combined Charging System) connector. This allows vehicle owners to access public charging infrastructure with a standardised plug wherever they go. However, this level of standardization does not yet exist for electric three-wheelers Many manufacturers use proprietary connectors leading to compatibility issues and a lack of universal public charging access,' says Ragavendra.
Electric autos used for transporting goods go to warehouses for charging; and those used for ferrying people are dependent on public charging stations or homes, he says.
Is it okay to charge an electric vehicle at home? Yes, but it may not be as fast as a public infrastructure point. Many prefer to charge vehicles at home for the convenience it brings. A Tangedo official says so far there is no restriction on charging electric vehicles at home for domestic use, but if a petty shop is offering it at a fee to users then they must have a separate meter with commercial tariff.

Korean industry giants bet on battery recycling as global EV market matures
South Korea's leading industrial players are ramping up their efforts in the electric vehicle (EV) battery recycling sector, reflecting growing expectations that the currently sluggish market will develop into a vital part of the battery value chain, the Korea Herald reported on June 20. The LG Energy Solution , the South Korea's top battery manufacturer, has recently established joint ventures in both Europe and the United States -- partnering with France's Derichebourg and Toyota Tsusho Co., respectively. These initiatives mark LG's first direct entry into recycling operations in these key global markets. Meanwhile, SK Ecoplant, the construction and engineering arm of SK Group, is expanding its European operations in the Netherlands. The facility will add an annual processing capacity of 25,000 metric tons of black mass, with the expansion slated for completion in 2025, the South Korean English-language daily newspaper added. Going further, Posco-GS Eco Materials -- a joint venture between Posco Holdings and GS Energy, with ownership split 51:49 -- has also made a notable move by acquiring full ownership of its recycling unit, Posco HY Clean Metal. This was achieved by purchasing the 35 percent stake held by China's Huayou Cobalt in April, the South Korea's news platform added. These strategic shifts come amid a prolonged downturn in the battery recycling sector, fueled by weakened EV demand and falling prices of core battery minerals such as nickel, lithium, and manganese. Lithium carbonate prices, which exceeded 450 Chinese yuan (USD 63) per kilogram in January 2023, have plummeted to about 50 yuan. Nickel has also seen a steep drop from over USD 31,000 per ton to around USD 20,000. As a result, SungEel HiTech -- one of only two battery recycling companies listed on Korea's tech-heavy Kosdaq -- has faced falling profitability and declining free cash flow for two consecutive years. A joint recycling venture between SungEel HiTech and SK Innovation, announced in 2022, has been postponed indefinitely. Additionally, SK Ecoplant's planned facilities in Gyeongju, North Gyeongsang Province, and in Kentucky have shown little to no progress for several years. The news report added that the Korean industry watchers expect a sharp rise in used EV batteries reaching end-of-life status, generally around 10 years after initial use -- a timeline that aligns with the global EV sales boom in the 2010s, which topped one million units by 2015. With global EV adoption continuing to rise, the battery recycling market -- valued at USD 8 billion in 2022 -- is forecast to grow to as much as USD 53.57 billion by 2030, according to SNE Research. Experts argue that participating in the recycling segment is becoming crucial for maintaining competitiveness in the battery industry, especially as regulatory pressure mounts globally for the use of recycled materials. The European Union, for instance, mandates that EV batteries sold in the region must contain minimum percentages of recycled metals by 2031: 16 percent for cobalt, 85 percent for lead, 6 percent for lithium, and 6 percent for nickel. These thresholds will increase by 2036. In the United States, the Inflation Reduction Act excludes EVs from tax credits if key battery materials are sourced from "foreign entities of concern," further pushing manufacturers to procure materials domestically -- often through recycling.

Three-wheeler EV adoption gains traction in Tamil Nadu
Three-wheeler electric vehicle (EV) penetration in Tamil Nadu so far in the calendar year 2025 has already surpassed the numbers for 2024, data show. As per data available on Vahan portal, a total of 2,802 electric three-wheelers have been registered in 2025 till May. EV adoption or penetration (measured in terms of EV sales as a percentage of the total vehicle sales) stood at 16.07% in 2025, as compared to 13.92% for the entire 2024. 'In Tamil Nadu, there has been consistent rise in the penetration of EVs, with 'Passenger Autos' rising from almost 4% in 2023 to above 8% in 2025. The penetration in the cargo vehicle segment is above 27%,' Roy Kurian, business head – last-mile mobility, Montra Electric, said. Montra Electric is the electric mobility brand of the Murugappa Group. 'State-level incentives — road tax exemptions and registration benefits — have helped lower the entry barriers for drivers. At the same time, availability of more reliable products has opened up a wider market,' Mr. Kurian said. Tamil Nadu has also been at the forefront in the usage of EVs, such as e-carts being used in waste management activities. The fast pace at which the government is focused on developing Public Urban transport like Metro Rail will also support growth of the last-mile EV solutions, he added. Montra Electric has seen strong traction for its EV three-wheelers in Tamil Nadu, with demand emerging from not only Chennai but also being driven by cities such as Madurai, Kanniyakumari, Coimbatore, Tirunelveli, and Tiruchi. Most of the initial customers being those who can charge the vehicles at their homes. Smaller towns, where travel distance is less, are quickly picking up EVs, Mr. Kurian said. The cargo segment is being driven by the logistics and e-commerce players, who have realised the benefits of EVs over internal combustion engine (ICE) vehicles for better profitability. They can also set up the charging and service infrastructure to support the fleet relatively easily, he said. However, Mr. Kurian said there was a long way to go for both the industry and government to come together on specific areas, including: affirmative actions to discourage purchase of ICE three-wheelers and actively move to EVs and earmarking space for charging stations in the key market areas, Mr. Kurian said. Ragavendra Ravichandran, co-founder and chief operating officer, Plugzmart, a Chennai-based EV charger manufacturer, said the increase in adoption was mainly driven by economics — rising fuel prices and the much lower running cost of EVs. K.P. Karthikeyan, chief executive officer and director of Zeon Electric Private Limited, said even though three-wheeler adoption was rising, the numbers were still below the national average (which is at 45.27%). With the State government looking at improving charging infrastructure, the numbers will go up, he added. Sriram J, senior manager, charging infrastructure at said availability of more product options and drivers' comfort level had been driving the three-wheeler EV adoption. K.P.

Tata Motors expects to achieve 30% EV penetration ahead of target: Chandra
Tata Motors is hoping to beat its target year of 2030 and have 30 per cent of its portfolio comprising electric vehicles (EVs), according to Chairman N Chandrasekaran, who was speaking at the company's last annual general meeting (AGM) ahead if its demerger. EVs constitute 15 per cent of the company's sales. As it eyes growth in EVs, the company is keeping a close watch on shortages in rare-earth magnets (critical EV components) and also exploring alternative sourcing options. 'We are not facing any issues. We are able to source the magnets that we need and we also have plans for having the right level of inventory,' Chandrasekaran said. He added that the company was working with the government and also sourcing from alternative sources. 'As of now this is not a concern, but this is something that we are watching carefully,' Chandrasekaran said. Earlier this week R C Bhargava, chairman, Maruti Suzuki India, had said the company had stocks of rare-earth magnets imported from China and those would last until the end of July. It will prepare a 'contingency plan', including exploring alternatives if the issue remains unresolved by then. Analysts, however, have pointed out that China's export restrictions on rare-earth magnets could delay the penetration of EVs in India. India Ratings and Research said on Friday it believed that while the immediate impact on auto sales in FY26 was expected to be limited, given the low level of EV penetration in the country, prolonged constraints could disrupt the overall automotive production, including internal combustion engine (ICE) vehicles. Rare-earth magnets are used in a major way for motors and batteries, two of which are the core components of an EV. A prolonged restriction on the import of these could hinder EV penetration in the country, the analysts said. 'In contrast, the amount of rare-earth magnets used in ICE components is fairly little and given their alternatives available, the overall production of ICE vehicles is unlikely to be material,' said Shruti Saboo, director, India Ratings. Chandrasekaran said the net-zero (emission) goal for Jaguar Land Rover (JLR) was 2039, for passenger vehicles (PV) 2043 and for commercial vehicles (CV) 2045. However, on hydrogen-powered vehicles, Chandrasekaran said market growth in the segment would happen in the near-term. The company has 12 hydrogen vehicles (CVs) running and will also continue to invest in the technology. The cost of operation and cost of production are way too high for hydrogen vehicles to gain market traction, he said. As for the impact of tariffs, the chairman said they were a major issue, primarily for JLR. 'From 2.5 per cent the tariffs would have gone up to 27.5 per cent, but with the United Kingdom-United States trade deal, they would not drop to 10 per cent. The impact of this is around 1.6 billion pounds. But JLR has taken a lot of steps to reduce the impact of this to around 600 million pounds,' Chandrasekaran said. The Tata Motors demerger is expected to happen in the October-December quarter. The passenger-vehicle company will list first, and the commercial-vehicle company will do so a couple of months later. PB Balaji, group chief financial officer, said: 'The intention is to carry the legacy of the automotive group, the continuity of purpose, strength of culture and clarity of execution.' The free cash flows, profitability and return on capital employed (RoCE) will continue after the demerger of the firm. Looking ahead, Balaji said he expected the free cash flow in the commercial-vehicle business to be 7-9 per cent of revenue (post tax) by 2027.
