UK researchers have found a way to reduce the risk of electrocution in electric vehicles, and US utility Duke Energy says it is investigating how Ford F-150 lightning can be used as grid input. Chinese carmaker Geely posted disappointing first-half results, while IHS Markit said it expects strong uptake of battery electric vehicles in Europe by 2030.
York University Researchers have developed a new technology that is effective in reducing the risk of electrocution caused by electric cars in major road accidents. A major safety issue in EVs today is the high voltage of the DC ‘bus’ – the electrical circuits that store power at high voltage and distribute power to other circuits in the car. To reduce power surges during collisions, a circuit breaker is installed to disconnect the battery and boost converters, which normally work to boost the voltage. But the circuit breaker prevents power surges, it does not reduce the voltage set in the DC bus. “The bus voltage in most electric car models is 400V, which is 230V higher than our home voltage and 380V higher than the industrial standard,” said Yihua, from York’s School of Physics, Engineering and Technology. “To greatly reduce the risk of fatal electric shock in a car accident, we want the voltage to be 60 volts or less, and to drop to that level in less than five seconds.” New research by IEE Transactions on Power Electronics It involves designing a DC bus hybrid model that uses both the car’s internal workings and external pathways that allow safe power flow. The team developed a system that prevents energy from accumulating in the event of a circuit damage, which consumes the remaining voltage, which increases the risk of electrocution. Even in the event of an electrical failure, the team developed a power dissipation algorithm that reduces the voltage output of the DC bus to protect other circuits in the vehicle. The technology has now been tested in a car powertrain test system, and the team has shown that the voltage drops to 60V in less than five seconds after damage to the circuits.
Duke Energy He said he will explore the vehicle-to-grid potential of Ford’s F-150 Lightning all-electric vehicles in Florida as grid inputs. The U.S. utility will begin an R&D test program in the state to evaluate the new truck’s high-capacity batteries that can provide backup power for homes and small businesses for up to 10 days during power outages. It will add about five Ford F-150 Lightning trucks to its Florida fleet and conduct additional technology trials, focusing on homes with solar and storage. The pilot focuses on real-world use cases with the Ford F-150 Lightning grid, such as how the vehicles connect to other customer-owned distributed energy resources, how the batteries function in the event of a disconnection, and how the vehicles behave. It was used to feed the grid during peak periods, and how such usage affects batteries over time.
Jilly It plans to increase sales and exports of EVs following the pandemic lockdowns and supply chain problems. Shipments of AVs will account for more than 30% of total sales by the end of 2022 and will continue the upward trend in 2023, according to Geely CEO Gan Jiayu. He added that the Chinese automaker will work to strengthen exports to Europe, the Middle East, Asia Pacific and Latin America. The company’s export sales rose 64 percent, but posted a lower-than-expected half-year profit. It delivered 613,842 vehicles in the first half – just over a third of its annual figure of 1.65 million. “The group’s sales performance in the first half of 2022 was below management’s expectations, primarily due to production and sales disruptions caused by outbreak prevention and control in some cities in China and global chip shortages,” the company said.
IHS Markit It has published a new white paper predicting that the market share of battery electric vehicles (BEVs) among passenger vehicles in the EU will grow from 9.8% in 2021 to 67.9% in 2030. 56 GWh in 2021. The European Union lithium-ion battery passenger vehicle market is expected to reach 3,000 GWh by 2030. But the price of battery raw materials will peak in 2022 and then decrease from 2023 to 2024. Nickel prices will continue to see significant gains. In the year Volatility before easing in 2021, lithium spot price movements remain bullish in the short term due to logistical challenges in China. “A strong balance of supply and demand may continue in the future, but current spot prices are at very high levels and are expected to ease from such high levels,” the research firm said. By 2030, NCM811 battery chemistry is expected to dominate the EU passenger vehicle market.
CareEdge Demand for EVs in India will grow more slowly than previously estimated over the next three years, says a new report. It expects domestic EV sales to grow at a modest 75% annually over the next three years. The large-scale transition to EVs in various categories, previously expected to happen after 2023, could be delayed by at least three years. Two-wheeler EVs will continue to account for more than 90% of demand in the interim. [given their cost parity with ICE vehicles in this segment]” said the research firm. The analysts said that the shift to EVs in the car segment will continue to be driven by relatively high car prices as well as lack of infrastructure in India. Demand for EVs will suffer due to tight supply of key battery raw materials including nickel, lithium and cobalt, he said.
Volkswagen And Mahindra & Mahindra announced plans to expand their business relationship and shift the Indian car market to electric vehicles. The companies have signed on to supply MEB electric components for Mahindra’s new Anglo Electric platform, which has been under a partnership agreement since earlier this year. The partnership plans to have a lifetime volume of over 1 million units and will include five fully electric SUVs with MEB components. The two companies will explore opportunities for collaboration in a broad strategic partnership to accelerate the electrification of the Indian automobile industry.
Australian government It wants to push more EVs into the domestic market and introduce fuel efficiency standards to improve their capabilities. EVs now account for just 2% of new car sales in Australia – a rate five times lower than the global average. Climate Change and Energy Minister Chris Bowen says expanding Australia’s EV market and improving fuel efficiency standards will be the focus of the new National Electric Vehicle Strategy. Bowen said a discussion paper on this will be released for consultation in September. The government wants to set a low-emission vehicle target of 75% of new leases and purchases for the Commonwealth fleet by 2025 to encourage more EV model introductions and expand the resale market.
Bank of Australia It is looking to phase out fossil fuel car credits from 2025 to encourage more people to go electric. Sasha Courville, the bank’s chief impact officer, said the ad sends a message: “If you’re considering buying a new car, seriously consider an electric vehicle, for its impact on the climate and lifetime cost savings.” ” Courville Bank chose 2025 because the transition to electric vehicles needs to happen quickly. “With the right support policies, we believe it can bring more value for electric vehicles to Australia,” she said.
