As the US prepares for brutal heat, we found out how high temperatures affect EV range from battery range experts Recurrent.
Thanks to a heat dome over the US Midwest and Northeast, the National Weather Service says millions of people are facing “dangerously hot conditions” over the next five days. Heat index temperatures in the Northeast are expected to reach 105F (41C) in the coming week.
So, I checked out a new study from Recurrent, which provides EV battery health reports for owners, shoppers, and dealers. Recurrent’s study, “Summer & Hot Weather on Electric Car Range,” looked at real-world data from more than 7,500 electric cars in the US.
The short answer is that EVs work mostly fine when the temperature soars. Electric cars only lose 2-5% of range in temperatures below 90F (32C). Electric cars have robust thermal management to keep the batteries cool and safe.
However, Recurrent’s battery readings found that EVs can lose 20-30% of total range in scorching weather, ie, above 95F (35C).
When heat becomes a problem for EVs
Heat adversely affects EVs in two situations:
Leaving your EV battery at a very low percentage of charge. A car’s thermal management requires energy, so keep your battery charged to help the car keep its battery cool.
Letting a car sit for weeks in the hot sun. That’s harder on an EV than parking it in the shade or outdoors. If you have to leave your car at the airport for a week, putting it in a sheltered parking spot would be ideal, especially if extreme heat is forecast.
How air conditioning affects EV range
Using your A/C during normal summer conditions won’t reduce your range by a noticeable amount. But interior cooling, of course, requires energy, so extreme heat could cause range loss.
Air conditioning has much less of a negative impact on EV range than a resistance heater, so the range doesn’t begin to dip until the thermometer reaches 85F.
Cooling your EV’s cabin affects the range less than heating it in cold temperatures.
The best way to cool your EV
If you pre-cool your EV when plugged in, the A/C won’t affect your range. The most energy-intensive part of air conditioning is the initial cool down. It may take 3-5 kW of energy to get a 95F car to 70F, but it takes only around 1 kW to keep it at 70F.
Plus, electric air conditioners are simpler than mechanical ones, but still check your air filters and hoses regularly.
How EVs affect heat
If you want fewer days of extreme heat, driving an EV is one of the best things you can do. Fossil fuel-powered transportation is one of the most significant contributors to climate change; EVs help combat that.

As “extreme” weather events become more commonplace, the demand for reliable and portable energy continues to rise. In response to that growing demand for dependable off-grid power, Volvo has developed the new PU500 Battery Energy Storage System (BESS) designed to take electrical power when it’s needed most.
Designed to be deployable in a number of environments at a moment’s notice, the Volvo Energy PU500 BESS is equipped with approximately 500 kWh of usable battery capacity (up to 540 kWh total). More than enough juice, in other words, to power a remote construction site, disaster response effort, or even a music festival – anything that needs access to reliable electricity beyond a grid connection.
That’s great, but what sets the PU500 apart from other battery storage solutions is its integrated 240 kW DC fast charger.
“With an integrated CCS2 charger, the PU500 is designed to work with all brands of electric equipment, trucks, and passenger cars,” says Niklas Thulin, Head of BESS Product Offer at Volvo Energy. “This ensures that no matter what type of electric vehicle or machinery you rely on, the PU500 can provide the power you need, making it a truly flexible solution for any grid constrained site or location.”

The integrated charger in the PU500 has the impressive ability to charge a heavy equipment asset (be that an electric semi truck or something like a wheel loader) in under two hours. Its on-board capacity allows to fully recharge up to 3 electric HD trucks or 20 electric cars per day, making it an incredibly versatile disaster response asset.
In a bold bid to combat the crippling air pollution crisis in its capital, Delhi, Indian lawmakers have begun high-level discussions about a plan to phase out gas and diesel combustion vehicles by 2035 – a move that could cause a seismic shift in the global EV space and provide a cleaner, greener future for India’s capital.
Long considered one of the world’s most polluted capital cities, Indian capital Delhi is taking drastic steps to cut back pollution with a gas and diesel engine ban coming soon – but they want results faster than that. As such, Delhi is starting with a city-wide ban on refueling vehicles more than 15 years old, and it went into effect earlier this week. (!)
“We are installing gadgets at petrol pumps which will identify vehicles older than 15 years, and no fuel will be provided to them,” said Delhi Environment Minister Manjinder Singh Sirsa … but they’re not stopping there. “Additionally, we will intensify scrutiny of heavy vehicles entering Delhi to ensure they meet prescribed environmental standards before being allowed entry.”
The Economic Times is reporting that discussions are underway to pass laws requiring that all future bus purchases will be required to be electric or “clean fuel” (read: CNG or hydrogen) by the end of this year, with a gas/diesel ban on “three-wheelers and light goods vehicles,” (commercial tuk-tuks and delivery mopeds) potentially coming 2026 to 2027 and a similar ban privately owned and operated cars and bikes coming “between 2030 and 2035.”
Electrek’s Take

Last week, Parker Hannifin launched what they’re calling the industry’s first certified Mobile Electrification Technology Center to train mobile equipment technicians make the transition from conventional diesel engines to modern electric motors.
The electrification of mobile equipment is opening new doors for construction and engineering companies working in indoor, environmentally sensitive, or noise-regulated urban environments – but it also poses a new set of challenges that, while they mirror some of the challenges internal combustion faced a century ago, aren’t yet fully solved. These go beyond just getting energy to the equipment assets’ batteries, and include the integration of hydraulic implements, electronic controls, and the myriad of upfit accessories that have been developed over the last five decades to operate on 12V power.
At the same time, manufacturers and dealers have to ensure the safety of their technicians, which includes providing comprehensive training on the intricacies of high-voltage electric vehicle repair and maintenance – and that’s where Parker’s new mobile equipment training program comes in, helping to accelerate the shift to EVs.
“We are excited to partner with these outstanding distributors at a higher level. Their commitment to designing innovative mobile electrification systems aligns perfectly with our vision to empower machine manufacturers in reducing their environmental footprint while enhancing operational efficiency,” explains Mark Schoessler, VP of sales for Parker’s Motion Systems Group. “Their expertise in designing mobile electrification systems and their capability to deliver integrated solutions will help to maximize the impact of Parker’s expanding METC network.”

The manufacturing equipment experts at Nott Company were among the first to go through the Parker Hannifin training program, certifying their technicians on Parker’s electric motors, drives, coolers, controllers and control systems.
“We are proud to be recognized for our unwavering dedication to advancing mobile electrification technologies and delivering cutting-edge solutions,” says Nott CEO, Markus Rauchhaus. “This milestone would not have been possible without our incredible partners, customers and the team at Nott Company.”
In addition to Nott, two other North American distributors (Depatie Fluid Power in Portage, Michigan, and Hydradyne in Fort Worth, Texas) have completed the Parker certification.
Electrek’s Take

With the rise of electric equipment assets like Bobcat’s T7X compact track loader and E10e electric excavator that eliminate traditional hydraulics and rely on high-voltage battery systems, specialized electrical systems training is becoming increasingly important. Seasoned, steady hands with decades of diesel and hydraulic systems experience are obsolete, and they’ll need to learn new skills to stay relevant.
Certification programs like Parker’s are working to bridge that skills gap, equipping technicians with the skills to maximize performance while mitigating risks associated with high-voltage systems. Here’s hoping more of these start popping up sooner than later.
