In the second quarter of this year, Ford sold 23,957 electric vehicles in the United States, a 61% increase from the same period last year, when total electric vehicle sales were 14,843. Meanwhile, Ford’s sales of hybrid vehicles rose 55 percent year over year. However, sales of internal combustion engine cars were down 5 per cent year on year.
Ford saw double-digit sales growth for several of its electric vehicles. Sales of the Ford F-150 Lightning rose 76.9% to 7,902 units. While new competitors such as the Tesla Cybertruck and the Chevrolet Silverado EV RST have all hit the U.S. market, the Ford F-150 Lightning remained the best-selling electric truck in the U.S. in the first half of the year, with 15,654 units sold.
Second-quarter sales of the Ford Mustang Mach-E were up 46.5% year-over-year to 12,645 units. In the first half of this year, 22,234 units of the Mustang Mach-E were delivered, the best performance ever. Sales of Ford’s E-Transit electric van continued to climb in the second quarter, rising 95.5 percent to 3,410 units from a year earlier.
In the first half of 2024, Ford sold a total of 44,189 electric vehicles in the U.S. market, up 72% from 25,709 in the same period last year.
Ford CEO Jim Farley said the automaker is shifting to smaller, more affordable electric vehicles to close the gap with Tesla and fend off competitors like BYD worldwide. Referring to Americans’ love affair with “larger vehicles,” Farley said smaller electric vehicles are “very important to driving the decarbonisation of American society and the development of electric vehicles.”
Ford’s surge in electric vehicle sales in the US market is enough for it to continue to overtake General Motors. In the United States, GM delivered 21,930 electric vehicles in the second quarter, compared with 38,355 in the first half of 2024.
GM is also ramping up production by introducing new models, with electric models such as the Chevrolet Blazer, Equinox and Silverado coming to the U.S. market. While Tesla did not give specific sales figures by region, its second-quarter electric vehicle sales worldwide exceeded expectations, delivering 443,956 electric vehicles and remaining №1 in the U.S. market.
As competition in the U.S. electric vehicle market intensifies, other competitors, including Hyundai and Kia, also set new EV sales records in the second quarter. Hyundai Motor, for example, set a new sales record with its IONIQ 5 model, which sold 18,728 units in the first half of the year. Meanwhile, sales of Kia’s first three-row electric SUV, the EV9, are also climbing.

link hidden, please login to view Electric car maker Fisker said on June 12 it would recall more than 18,000 vehicles in North America and Europe due to software glitches and non-compliance with safety standards, the latest setback for the cash-strapped electric car start-up.
Fisker is voluntarily recalling 11,201 Ocean vehicles sold in the United States, Canada and Europe to fix a software issue that could cause the vehicles to enter safe state protected mode, potentially causing the motors to lose power.
In addition, Fisker is recalling 6,864 Ocean vehicles in the United States because the dashboard and display prompt ICONS do not comply with the Federal Motor Vehicle Safety Standard (FMVSS). The company will also recall an additional 281 vehicles in Canada as a result.

The startup plans to address these issues with an OTA update to Ocean OS in-car software by June 30. The company said vehicles that have been updated to the latest version of the software are not affected by the recall.
The National Highway Traffic Safety Administration (NHTSA) is investigating four safety incidents involving the Ocean SUV, the only Fisker model currently in production. NHTSA said last month that it was investigating complaints that the Ocean Automatic Emergency Braking System was accidentally activated.
Cash-strapped Fisker is looking for alternatives after talks with a major automaker over a potential investment collapsed. The company’s Austrian subsidiary filed for bankruptcy protection in May.

link hidden, please login to view According to foreign media reports, the Australian Federal Automobile Industry Chamber of Commerce released automobile sales data in May, the month of new car sales in Australia hit a record high. Sales of hybrid vehicles doubled year on year to reach 15.8 percent of the market, compared with a 0.4 percent increase in electric vehicle sales.
Almost one in every four new cars in Australia is currently a low-emission vehicle, so hybrid and electric vehicles are taking a greater share of the market. Meanwhile, Australians’ love affair with larger cars is still on the rise, with SUVs still dominating and ute sales continuing to grow.
This trend has more than doubled the popularity of hybrid cars in 2024, with more than 66,000 units sold, compared to less than 30,000 in the same period in 2023.
Electric vehicle sales also increased in Australia in May, with more than 8,900 units sold, accounting for 8.1 per cent of all new car sales, with more than 40,000 new electric vehicles on the road in Australia in the first five months of the year.
Tony Weber, the chamber’s chief executive, said the auto industry is working hard to meet the needs of drivers. “The continued growth in vehicle sales underscores consumer confidence and demonstrates the industry’s ability to meet the diverse needs of Australian consumers in the face of the current economic challenges,” he said.
However, large vehicles remain a popular choice for drivers regardless of fuel consumption, with SUVs accounting for more than half of vehicles sold and light commercial vehicles accounting for 22 percent of new vehicles. UTE also took three of the top five best-selling cars in May, with the Ford Ranger taking the top spot, followed by the Toyota Hilux and Isuzu’s D-Max light truck in fourth place.

Toyota was again the top-selling car manufacturer in Australia for the month, followed by Ford, Mazda, Kia and Hyundai. The data also showed a drop in sales for electric car leader Tesla, with the US company selling 3,567 vehicles in Australia in May, compared with 4,476 in the same month last year.
Its main electric car rival BYD, however, saw sales climb, with the Chinese company selling 1,914 electric vehicles in the month, up 32 percent from a year earlier.
The growing sales of electric and hybrid vehicles come ahead of the introduction in January of Australia’s first fuel efficiency standard, a legal standard that will set emissions limits on carmakers’ fleets of passenger cars, large and commercial vehicles in an attempt to reduce transport emissions by 2030.

This winter, extreme weather patterns have been disrupting daily routines nationwide. Flooding, snowfall and subzero temperatures all have taken a toll on our roadways and vehicles, leaving many stranded or unable to leave their homes. For those who can make it out to the streets, driving conditions can be hazardous. Having a reliable, fully charged battery is critical during these weather events.
Several news reports lately have highlighted the negative effects of extreme weather on the growing segment of electric vehicles (EVs). Just as the lead-acid batteries found in conventional automobiles suffer during cold snaps, the battery packs found in EV and hybrid vehicles endure a similar kind of stress. As temperatures drop to freezing and below, EV efficiency (measured in miles per kilowatt-hour, or m/kWh) can be reduced by as much as 34%, shortening effective range. Unfortunately for EV owners, the reduction in range brought about by these cold temperatures means more frequent charging events.
As temperatures plunge, these charging events can take even longer. EV batteries need to achieve a minimum internal temperature before accepting a charge, so the vehicle prioritizes battery preheating before it begins the actual charging process, which itself is less efficient at low temperatures. These delays can lead to lines at public charging stations, and increased numbers of immobile EVs stranded roadside when batteries go flat before reaching a charging station.
Our customers with EVs still have the same type of 12-volt auxiliary battery commonly found in ICE-powered vehicles featuring stop-start technology. The BCI groups 400 and LN1 are just two of the popular AGM applications in this category. For ESS or hybrid vehicles, this battery is necessary for powering accessories when the engine is off, while EVs need a 12-volt power source isolated from their high-voltage traction systems. Maintenance-free AGM batteries are most often used in these applications, due to their ability to recharge quickly and a longer service life when compared to other types of lead-acid batteries.
Lithium-ion batteries (like those used in cordless tools around the shop) are becoming a popular auxiliary option for EVs as well as ICE-powered vehicles. Lithium-ion batteries have a higher energy density than their lead-acid counterparts, so they can pack the same amount of power into a smaller (and lighter) case. Tesla has been using lithium-ion technology for its auxiliary battery in the Model 3, S, X and Y since 2021.
Intelligent Battery Sensors
As batteries and charging systems become more advanced, use of an intelligent battery sensor (IBS) is becoming more commonplace. BMW has used battery sensors since 2002, and uniquely requires “registration” to notify the PCM that a new battery has been installed. This update allows the PCM to tailor the battery-management system to the output of the new battery. The sensor now has a reset “baseline” to make decisions on charging voltage, idle speed and other parameters that affect drivability and battery life. In addition to measuring current in and out of the battery, the IBS also may monitor battery state of charge, state of health and even temperature.
No matter if you’re daily-driving an ICE or an EV, a properly maintained battery and charging system is critical to reliable starting in all kinds of weather. Fortunately, given today’s battery technologies, it’s even easier to maintain and monitor these systems than ever before!
