EV share of new car sales in Singapore crosses 20% in July 2023

STRAITS TIMES https://www.straitstimes.com/singapore/transport/ev-share-of-new-car-sales-in-singapore-crosses-20-in-july-led-by-byd-tesla-bmw SINGAPORE – Car buyers are gradually but surely warming to electric vehicles (EV), with one in five new cars registered in July being battery-powered models. According to Land Transport Authority (LTA) figures, 486 new electric cars were registered in July, accounting for 20.4 per cent of the 2,382 passenger cars put on the road that month. This compared with a share of 18.5 per cent in June, and 11.7 per cent at the end of 2022. The latest tally brings the share of EVs in the first seven months of the year to 15.2 per cent, or 2,378 cars. In the first six months, the EV share was 14.3 per cent (1,892 cars) – up from 13.4 per cent (1,462 cars) in the January to May period. July’s spurt was spearheaded by BYD, Tesla and BMW. For the seven months, BYD, Tesla and BMW registered 474, 451 and 400 cars, respectively, to become the three best-selling electric brands. Mercedes-Benz followed at a distance with 249 cars, and Hyundai with 200. Ranked by country, German EV brands led the way, with a share of 36.2 per cent, or 861 cars, followed by Chinese brands with 23.4 per cent, or 577 cars, and American makers with 19 per cent, or 451 cars. This may change. Dr Zafar Momin, an adjunct associate professor at the National University of Singapore Business School and a former automotive expert at Boston Consulting Group, said: “The Chinese will eventually lead because they are furthest ahead in EV market development. “The Japanese, depending on whether they do create superior batteries, will slowly but surely join the top three as they are the leading mass market carmakers.” Observers said uncertainty over the status of EV tax breaks may have fuelled the sharp uptake in registration of electric models in July. For instance, the EV Early Adoption Incentive – which gives a rebate of 45 per cent off the Additional Registration Fee, capped at $20,000 – is due to end on Dec 31, 2023. Rebates in the revised Vehicular Emissions Scheme have not yet been spelt out. Industry players however, expect the authorities to pare down monetary enticements to encourage EV adoption – just like they had done for commercial vehicles. As at April, incentives for cleaner commercial vehicles were halved to $15,000 for those that meet criteria for Band A emissions, and $5,000 for those meeting criteria for Band B. Singapore University of Social Sciences associate professor Walter Theseira reckons that EV adoption is currently held back because Japanese makers do not have a range of products, and family-oriented options such as seven-seaters are not yet widely available. “It is more realistic to see a potential tipping point closer to the latter half of this decade, when we will have more COEs (certificates of entitlement), and prices are expected to fall. And based on current progress in battery technology, we also expect to see substantial improvements in range, charging speed and cost,” he said. “We also expect Japanese carmakers to have more credible electric models by then. And the Chinese EV brands should have more established reputations, too.” But Prof Theseira added that the tipping point may not happen if all these factors do not fall in place during the COE supply boom years of 2025 to 2029, when “the majority of car owners will replace their cars”. As at end-July, there were 8,873 electric cars on the road, accounting for merely 1.4 per cent of the passenger car population of 650,323, according to LTA figures. Together with other vehicle types, there were 12,733 EVs here at end-July, or 1.3 per cent of the total vehicle population of 968,537.

High Electric Vehicle Adoption: Grid Reinforcement vs Smart Charging

Accommodating Charging Load Due to High Electric Vehicle Adoption and Tackling Grid Impacts: Grid Reinforcement vs Smart Charging Written by Angshu Plavan Nath and Zakir Hussain Rather https://smartgrid.ieee.org/bulletins/june-2023/accommodating-charging-load-due-to-high-electric-vehicle-adoption-and-tackling-grid-impacts-grid-reinforcement-vs-smart-charging   Electric vehicles have seen rapid growth as a response to increased concerns over global warming and climate change. By eliminating the tailpipe emissions, the EVs would help in improving the local air quality while also being a tool for energy security [1]. Powering these fleets of EVs can add a significant load to the electricity grid. While the additional energy needed to power the EVs would roughly constitute 2.7% of individual countries’ total energy generation, the impact on the local energy distribution is far more significant [1]. The distribution grids were designed to cater to the traditional loads in the system. With the increasing adoption of EVs in the grid, the power infrastructure may face different challenges such as voltage drops, overloading in grid infrastructure, congestion, phase imbalance, etc [2]. To address the grid impacts of increased EV adoption on the electrical networks, large-scale reinforcement of the electrical grid may be needed. However, the requirements would be highly dependent on the individual grid networks, the local EV growth, and the headroom availability in the network. Grid reinforcement is not only capital-intensive but also time-consuming.   While grid reinforcement may be inevitable, it can be deferred by controlling and coordinating the charging of EVs, thereby reducing the stress in the grid. In smart charging (V1G), the EV charging is controlled by shifting the time of charging and regulating the charging power depending on the operating conditions of the network and the requirements of the EV owner, i.e., an external controller controls the EV charging based on predefined objectives and constraints. Unlocking smart charging requires different components and infrastructure as mentioned below:     Smart Charging Capable Electric Vehicle Supply Equipment: The EVSE that is being used to charge the vehicle should have smart charging capability with communication capabilities. Smart chargers are generally 20%-70% costlier compared to similarly rated dumb chargers, dependent on the connectivity features such as LAN, WLAN, Bluetooth, etc. [3] Smart Meter: The next important piece of equipment to facilitate smart charging is a smart meter, to enable logging of energy consumption with time of use. The smart meter also acts as the communication gateway between the utility and the user. With most utilities already moving towards replacing traditional energy meters with smart energy meters around the world, this would not constitute an additional expense for smart charging. Charging Management Software: The charging management software is the central hub that coordinates the charging of the EV. The cost of the management system is vendor specific and depends on the included functionalities. Information and Communication infrastructure: The information and communication infrastructure includes the data storage, management, and analysis component and the physical communication infrastructure that needs to be installed such as fiber cables/ telephone lines/ radio wave transmission system, etc. based on the connection technology being used. For an electric utility like a distribution network operator, this would probably be one of the added investments to enable smart charging. However, the same infrastructure could also be used for other smart grid applications. The different requirements for the implementation of smart charging have been provided in Figure 1.   Figure 1. Requirements for enabling smart charging [4] Compared to grid reinforcement, where the utility has to invest significant capital on the grid infrastructure, in smart charging the investment made by the utility is significantly reduced. A study at Hamburg’s distribution grid in Germany determined that a 9% increase in the EV stock in the city corresponding to 60,000 EVs would cause bottlenecks in 15% of the distribution network feeders in the city. Grid reinforcement to accommodate the EVs would need an investment of at least 20 million Euros, while the estimated investment for smart charging is only around 2 million Euros. So, the cost of implementation of smart charging to control the EV load is 90% less than the grid reinforcement cost [5]. The Green eMotion project conducted across different cities in the European Union also found that smart charging can reduce the grid reinforcement cost by 50%, while a separate study by the Sacramento Municipal Utility in the United States found that smart charging can reduce grid reinforcement costs by 70% [5]. Another much cheaper alternative to communication-based active smart charging is the use of tariffs for passive control of EV charging. The use of time-based EV tariffs such as time-of-day, time-of-use, and real-time pricing incentivizes the EV user to shift their charging to off-peak periods leading to a potential reduction in the peak load of the network [6]. Using such passive smart charging, the cost of implementation for the utility is further reduced, as they do not need to invest in any additional information and communication infrastructure other than that smart metering infrastructure. Conclusion With the increasing penetration of electric vehicles, the electrical grid is expected to experience various technical issues unless adequate countermeasures are in place. While grid reinforcement may be needed, the requirement may be significantly reduced and deferred by controlling the charging profile of EVs through the use of smart charging.   Acknowledgment This work was supported by the India-EU collaborative project SUSTENANCE funded by the Department of Science and Technology (DST) on the Indian side and the European Commission on the EU side.     References IEA, “Grid Integration of Electric Vehicles: A manual for policy makers,” International Energy Agency, 2022.

Vietnam promotes the EV industry and green transition

The Ministry of Transport (MoT) submitted an incentive for  #EV producers and usersto the Government to promote the transition from fossil fuel cars and reduce GHG emissions toward net zero by 2050. Accordingly, about 1,000 USD would be subsidized for each EV purchase, which aimed to change consumption behavior away from fossil fuel vehicles. Three types of EVs, including battery-powered EVs, fuel cell electric vehicles (FCEVs), and solar Evs, may receive incentives. The MoT proposed to add EV manufacturing and assembly and battery production to the list of industries that receive special investment incentives, as well as an exemption and reduction of import tax on equipment, production lines, and import of complete components and components for the production and assembly of EVs and batteries. For EV manufacturing, assembly, and maintenance companies, the ministry asked for a preferential mechanism that helps them access financial sources. A tax incentive mechanism for imported EVs is also needed. The registration fee for EVs is exempt for the first five years from March 1, 2022. In the next five years, from March 1, 2027, this will be 50% of the fee for petrol and diesel cars with the same number of seats. The MoT also proposed exemptions of import tax on components and equipment for electric charging stations, corporate income tax, land fee for five years, and a reduction of 50% for the next five years. The number of EVs in Vietnam has increased rapidly in recent years. From 2018 to 2021, there were only 167 vehicles. By July 2023, the number increased to nearly 12,600 with the majority are passenger cars and city buses. Source: Vietnam Initiative for Energy Transition (LinkedIn) Photo: VLR
