Anert installs demo project on Vehicle-to-Grid technology
Anert describes the concept as a game-changing one that transforms electric vehicles (EV) into mobile energy assets. V2G-enabled EVs can send power back into the grid, helping balance energy supply and demand. EVs charged during the daytime at relatively lower tariffs can export the power back to the grid during peak hours, AnerT officials said.
Electricity Minister K. Krishnankutty inaugurated the demonstration project at the Anert headquarters at PMG on Friday.
According to Anert, the demonstration project is being implemented in association with the India Smart Grid Forum (ISGF) which has technical assistance from the University of Delaware. The International Sustainable Energy Forum is also supporting it.
'If we can indigenise that technology, then the costs will also come down significantly. Now the technology is imported,' Anert director Narendra Nath Veluri said.
Mechanism involved
The bi-directional energy transfer between EVs and the grid is is made possible by using a bi-directional charger and bi-directional modular power unit (BMPU). The first is an advanced EV charger capable of two-way energy transfer. BMPU converts AC to DC during charging and the reverse during discharge.
Vehicles with V2G facility can be directly connected to the bidirectional charger for charging and discharging power to the grid. EVs having this facility are still rare.
One of the EVs owned by Anert was used for the purpose by replacing the DC Fast charging option with a BMPU. As part of the demonstration, Anert officials are also explaining the process behind retrofitting the e-vehicles.
The Anert demo project also coincides with a draft regulation on renewable energy prepared by the Kerala State Electricity Regulatory Commission which seeks to introduce the concept in Kerala's rapidly changing renewable energy sector. The draft notes that distribution licencees should facilitate the seamless integration of V2G-enabled EVs into the grid, subject to conditions.

EVs versus hybrids: Niti Aayog enters the chat
Federal think tank Niti Aayog is examining the lifecycle emissions of electric, hybrid and conventional vehicles to determine which technology is the cleanest, two people aware of the matter said. The move comes at a time when automakers have crossed swords on providing hybrids the same incentives as pure EVs. The study, which began earlier this month, is likely to be completed over the next few months, the people cited above said on the condition of anonymity. Varying incentives for EVs and hybrids across states have sparked an intense lobbying in state capitals, even as the Centre remains neutral to technologies in the quest for clean mobility. 'The need for such a study arose as contrasting claims emerged after some studies claimed EVs are more harmful when the entire supply chain and recycling are taken into account," one of the two people cited above said on the condition of anonymity. Green tussle While Maruti Suzuki India and Toyota Kirloskar, which manufacture hybrid models, say they deserve clean mobility incentives, Tata Motors and Mahindra and Mahindra say they should be reserved for the zero-emission EVs they make. EVs have no tailpipe emissions; however, in 2023, a study by the Indian Institute of Technology, Kanpur, showed that their manufacturing, usage and scrapping emit more greenhouse gases than the same processes for hybrid or fossil fuel-based study also said EV charging required coal-fuelled power, adding to EVs' overall carbon vehicles run on a mix of fossil fuels and a battery, and strong hybrids do not have a charging port like EVs and plug-in hybrids. The Niti Aayog study will take into consideration the full life-cycle analysis (LCA) for all types of vehicles. 'That means all vehicles – two wheelers, three-wheelers, four-wheelers, public and cargo transport, everything – and it will also look at all fuel powertrains," said the first person cited above. State moves The Union environment ministry is assisting the study by holding meetings with various stakeholders, the second person added. Email queries to the NITI Aayog and the environment ministry went unanswered. Mint reported on 22 July that while the Centre has maintained its stance of supporting all forms of clean mobility, some states have put their weight solely behind EVs. In a recent amendment to its state EV policy, Chhattisgarh removed incentives for hybrid vehicles. On 22 July, the Delhi government also deferred the enforcement of its controversial EV policy to March 2026, according to a report by news agency PTI, citing transport minister Pankaj Singh. An earlier draft of the Delhi EV policy had proposed equal incentives for hybrids and electric vehicles. 'Analysing use cases of vehicles, as well as the location of the vehicles is critical in an LCA,"said Gurudas Nulkar, professor and director, Centre for Sustainable Development, Gokhale Institute of Politics and Economics. 'The results from an LCA of a vehicle in Delhi will be very different from that in, say, Pune. That is because of the location of the two cities—w dDelhi is located in a flat region, while Pune is at the foothills of the Western Ghats. These diverse geographies will impact fuel efficiency." Lifecycle emissions Experts also said an LCA includes the emissions of extraction and transport of crude oil in the case of fossil fuel vehicles, as well as emissions in mining of critical minerals for hybrid and electric vehicles. The LCA of a vehicle where its components are imported will be different from that of a vehicle where parts are sourced locally, said Nulkar, an expert in industrial sustainability and environmental management. 'Similarly, different use cases for vehicles will yield varying results. There may be some cases with hybrids coming on top, and some with electric vehicles coming on top. The data used for most LCAs is secondary data, but it is very important to vet that data with physical visits, for instance, to manufacturing locations."

Motorists fume as Telangana RTA drives up service charges
Hyderabad: Applicants attempting to book slots for various transactions at the Regional Transport Authority (RTA) woke up to a rude shock on Sunday as they found a sudden increase in charges across several services. The revision came into effect at 2 am. The new rate-card shows that RTA has revised fees anywhere from Rs 100 to Rs 1,000 — with a fourfold jump in rates for a no-objection certificate (NOC). Available for Rs 100 until now, every NOC will now cost a motorist Rs 435. The cost for terminating vehicle agreements for four-wheelers has also been substantially increased from Rs 2,135 to Rs 3,135. Even commonly availed costs, right from learners' licence to vehicle hypothecation, have been brought under the new price umbrella. Motorists applying for any licence will have to cough up an additional Rs 100. The only exemptions: Permits, vehicle fitness assessments, taxes on vehicles from other states, permit cancellations, life taxes, and quarterly taxes. You Can Also Check: Hyderabad AQI | Weather in Hyderabad | Bank Holidays in Hyderabad | Public Holidays in Hyderabad 10k applicants to be impacted This revision — brought in three years after a hike on life taxes — is likely to impact at least 10,000 daily applicants at all RTA offices across the state. In 2022, the Telangana govt had raised life taxes under the Telangana Motor Vehicles Taxation Act, 1963, with increases ranging from 9% to 19% based on vehicle cost and category. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Unsold 2021 Cars Now Almost Free - Prices May Surprise You Unsold Cars | Search Ads Learn More Undo Many applicants, while ruing the sharp rise, also complained about the current revision being implemented surreptitiously without prior public announcement or notification. In fact, the RTA website: is yet to be updated with these new charges. Speaking to TOI, some said that they realised that the fees had been hiked only when they went to their RTA office to avail of a service. 'I tried to secure a learner's licence slot two days ago, when the fee displayed was Rs 450. However, I encountered technical issues and couldn't complete the booking. When I tried again on Sunday, I was surprised to see that the total amount had risen to Rs 550, with the service charge component having increased from Rs 100 to Rs 200,' said K Venkatesh, an applicant from Uppal. Move to increase revenue: RTA RTA officials said that the revision was aimed at enhancing revenue. 'Only service charges, which have remained unchanged for several years, have been increased. However, we need to monitor the situation for at least one month to assess how these increased charges contribute to revenue enhancement,' MM Chandrasekhar Goud, joint transport commissioner (IT & Vigilance), told TOI. Sources, on the other hand, hinted at the move being designed to accommodate tax exemptions being offered to EV buyers. Incidentally, since the Telangana govt implemented its EV policy on Nov 16, 2024, Rs 400 crore (approx) tax has been exempted through sales of more than 50,000 EVs. 'The govt's actions are unfair, as they offer complete tax relief to electric vehicles while parallelly raising service charges,' said M Dayanand, general secretary, Telangana Auto and Motor Welfare Union.'The facilities at their offices lack essential amenities for the public, and applicants are forced to wait in long queues for their turn. It is disappointing that despite these ongoing service deficiencies, the RTA has implemented increased service charges. I urge the govt authorities to reinstate the previous fee structure, in the interest of the public.'

After Tesla's desi debut, Vietnamese EV maker VinFast opens first showroom in India
Vietnamese EV manufacturer VinFast has opened its first showroom in India, located in Surat, Gujarat, ahead of the launch of its upcoming manufacturing plant, days after Tesla made its desi debut. Located in Piplod in Surat and spread out on 3,000 the facility will offer product experiences, vehicle purchase journeys, and after-sales support. The Showroom will showcase VinFast's upcoming range of premium electric SUVs - VF 6 and VF 7. India is also the first market where VinFast is launching the right-hand drive version of the VF 7 and VF 6. As part of its ambitious roadmap, the company aims to launch 35 dealerships by year-end, across 27 plus cities, the company said in a officially opened pre-bookings for its premium electric SUVs, the VF 6 and VF 7 on July 15, can now book their preferred VinFast premium electric SUV either at the exclusive showrooms or through the official website, with a fully refundable booking amount of Rs 21,000. The vehicles will be locally assembled at VinFast's upcoming factory in Thoothukudi, Tamil Nadu, reinforcing the company's long-term commitment to India as a strategic market and future hub for electric vehicle Sanh Chau, CEO, VinFast Asia, said, "The first VinFast Showroom in Surat, Gujarat is a symbol of our deep commitment to India. We are excited to bring the VinFast experience closer to Indian consumers. With this dealership in Gujarat, we aim to offer not just electric vehicles, but a complete ownership journey built on quality, trust, and service excellence."VinFast has entered the Indian market at a time when both local and global players are already establishing their presence, yet significant opportunities remain in this rapidly growing EV market is rapidly growing, with electric passenger vehicle sales rising from just 5,000 units in 2020 to over 113,000 in EVs currently make up less than 3% of total car sales, the central government's ambitious goal to increase this share to 30% by 2030 underscores the sector's tremendous latest player, VinFast, a small and unprofitable EV maker, briefly became the world's third most valuable automaker in 2023, behind Tesla and Toyota, after its Nasdaq debut sent shares soaring nearly 700%. Now, the company plans to open a car assembly plant in India by the end of in 2017, VinFast began making EVs in 2021. It is backed by Vingroup, Vietnam's largest conglomerate. VinFast in January last year signed an agreement with Tamil Nadu to invest as much as $2 billion in the country. Work on the plant started soon after, with an initial investment of $500 loss-making startup had initially planned to focus on America for its foreign sales, but slow progress in the United States, even before growing uncertainty caused by U.S. tariffs, pushed the company to change strategy. VinFast's entry in itself may not be a significant challenge for Tesla in India, but it points at a crowded EV space, which might make it hard for Tesla to cruise into the Indian VinFast, the real challenge begins with rivals like Tesla, which has already made its India debut. Tesla opened its first showroom in Mumbai's upscale Bandra Kurla Complex on July 15. The 4,000-square-foot space will showcase Model Y crossovers imported from China, priced at over $56,000 before taxes—roughly $10,000 more than the U.S. base price, according to Bloomberg.A second showroom is expected to open in New Delhi by the end of July, and Tesla has beefed up local hiring and secured warehousing space. But with no plans to set up a manufacturing plant in the world's third-largest automobile market, Tesla's entry into India is less about racking up immediate sales volume gains and more about gaging demand for its EVs and building up the brand's company has flirted with the idea of establishing a local manufacturing base — something the Indian government has courted and that could sidestep heavy import tariffs — but so far Tesla hasn't committed to doing Asia CEO Pham Sanh Chau has said the company doesn't view Tesla or BYD as direct competitors. Still, India's complex market dynamics—shaped by established Indian incumbents, pricing sensitivities, and evolving consumer preferences—present their own set of hurdles. As the EV race picks up pace, only time will reveal how VinFast navigates these challenges and where it ultimately stands.
