Hyundai and Toyota have both come under fire recently by the Advertising Standards Authority (ASA) over ads detailing the two firms’ quick charging times. The ASA found that the car adverts relating to Hyundai’s Ioniq 5 and Toyota’s bZ4X were ‘misleading’, due to many variables and limitations at play, especially when it came to the availability of the quickest EV chargers. But what are the different types of public EV chargers in the UK, how long can you expect a typical EV to charge with each and what is the availability of each type of charger like? Here we explain. AC slow charging – speeds up to 6kW There are two main types of EV charger – alternative current (AC) and direct current (DC). The first is used for slower charging, with the latter adopted for quicker speeds. If you’re in no rush, what’s classed as a ‘slow charger’ is the best bet. These are rated at speeds up to 6kW, and are ideal for if a car is parked up for an extended period of time. They are typically found in on-street chargers, including those in lamp posts. Let’s use Hyundai’s Ioniq 5 as an example. When equipped with the smaller 58kWh battery (an average size for an EV’s battery), it would take 16 hours to complete a charge. ‘Slow’ units are the second most popular type of charger in the UK. According to data from Zap-Map, one of the leading EV charging navigation firms, as of the end of May 2023, there were 10,699 slow chargers across Britain. AC fast chargers – 7kW to 22kW The most popular type of charger in the UK is what’s known as a ‘fast charger’. Rated between 7kW and 22kW, the smaller number is the most common type. These are often found in places where cars are usually stopped for several hours, such as in shopping centre and workplace car parks. The 7kW output is the typical output of a specific home EV charger, and with the Ioniq 5, it would take nine hours for a full charge. If you hooked up to a quicker 22kW charger, the time is reduced to six hours. According to Zap-Map data, there are 24,443 fast charging points currently in the UK. DC Rapid charger – 25kW to 99kW If you’re looking to speed things up a notch, it’s worth trying to find what’s known as a ‘rapid charger’. These are rated between 25kW and 99kW, though 50kW is the most common output. Often found in the car parks of supermarkets and fast food outlets, it would take around 45 minutes to charge the Ioniq 5’s 58kWh battery, according to Hyundai’s data, with one of these units. . As of May 2023, there were 5,182 rapid electric car charging points located across the UK. DC Ultra-rapid charger – 100kW + If you’re looking to top up an EV’s battery as quickly as possible, it’s an ultra-rapid charger that are the one to find. These are rated from 100kW upwards. They are typically found at motorway service stations, though specific EV hubs are now being set up with banks of these quicker units. Most Porsche dealers also have 350kW units, which are available to use by the public. It’s worth noting that every EV will have a maximum charging speed, with some older electric cars – or those with a smaller battery – having a maximum charging speed of 50kW, meaning there’s not a lot of point in using an ultra-rapid charger over a standard ‘rapid’ as it won’t charge it any quicker. But the Ioniq 5 is one of those that can charge at up to 350kW, however, meaning that in ideal conditions, it could take just 18 minutes to charge the battery to 80 per cent capacity. The trouble, however, as the ASA pointed out, is that there is limited availability of 350kW units. While, according to Zap-Map data, there are 3,302 ultra-rapid chargers across the UK, there are only around 70 individual locations across the whole of the UK that have 350kW chargers. The whole of Scotland, for example, has just six places that can deliver such charging speeds, while there are only three in Wales, and all of them are located in the south.

LONDON--(BUSINESS WIRE)--Jul 25, 2023--

Scientists believe they have discovered the cause of the megalodon's extinction – and no, it’s not Jason Statham. Experts have been conducting research on fossils of teeth from the biggest species of shark the world has ever seen, which went extinct around 3.6 million years ago and measured at least 15 metres long. Research published in the journal Proceedings of the National Academy of Sciences explains that the animal was actually partially warm-blooded. Unlike most cold-blood sharks, the body temperature is thought to have been around 27 degrees. The temperature is higher than the sea temperatures around the time. Sign up to our free Indy100 weekly newsletter Study co author Robert Eagle, who is professor of marine science and geobiology at UCLA, said [via CNN]: “We found that O. megalodon had body temperatures significantly elevated compared to other sharks, consistent with it having a degree of internal heat production as modern warm-blooded (endothermic) animals do.” They were able to prove that the animals were warm-blooded by analysing how carbon-13 and oxygen-18 isotopes were closely bonded together in the fossilised teeth. Senior study author Kenshu Shimada is a paleobiologist at DePaul University in Chicago, who said: “A large body promotes efficiency in prey capture with wider spatial coverage, but it requires a lot of energy to maintain. “We know that Megalodon had gigantic cutting teeth used for feeding on marine mammals, such as cetaceans and pinnipeds, based on the fossil record. The new study is consistent with the idea that the evolution of warm-bloodedness was a gateway for the gigantism in Megalodon to keep up with the high metabolic demand.” The fact it was warm-blooded means that regulating body temperature could have been the cause of its eventual demise. The Earth was cooling when the animal went extinct, which could have been a critical factor. “The fact that Megalodon disappeared suggests the likely vulnerability of being warm-blooded because warm-bloodedness requires constant food intake to sustain high metabolism,” Shimada said. “Possibly, there was a shift in the marine ecosystem due to the climatic cooling,” causing the sea level to drop, altering the habitats of the populations of the types of food megalodon fed on such as marine mammals and leading to its extinction. “One of the big implications for this work is that it highlights the vulnerability of large apex predators, such the modern great white shark, to climate change given similarities in their biology with megalodon,” said lead study author Michael Griffiths, professor of environmental science, geochemist and paleoclimatologist at William Paterson University.
