Experts Say EVs Will Soon Charge in Just 10 Minutes

According to experts in the industry electric vehicle charging times will plummet over the next five years and that even high capacity batteries should be able to be charged in less than ten minutes, taking no more time than a stop at your favorite gas station.
This is a two-part prediction as both ultra-fast charging and the way batteries are designed need to be handled. In the case of the batteries this will likely be improvement on the current chemistry and not something entirely new.

Currently the majority of EVs use 400V electrical systems. These are rated as high-voltage systems.

To get more power in watts than an EV can deliver—the charge it will accept—either voltage or current need increasing. Higher current requires bigger cables, heavier duty cables and thicker insulation; all of this creating a lot more heat. Rather than this, the voltage could be increased. Porsche has introduced the 800V electrical system which gets us two things we want: higher performance and lower charging times.

Last year Ionity introduced 150kW and some ultra-rapid charges running at 350kW in their public charging stations. The Porsche Taycan is the first vehicle able to take advantage of the 350kW chargers using its 800v electrical system.

Porsche claims that a Yaycan battery can get from a 5% charge to 80% charge at one of Ionity’s stations in just over 20 minutes. Even then the Taycan isn’t calling on the full power of the charging station.

Remember this is a story in two parts, the second part being how quickly the battery cells can accept a charge. So the rest of the story waiting to be told is who comes up with the new battery technology that completes this half of the equation.

Experts Believe We Are Only 5 Years from 10 Minute Car Charges for EVs

Walmart Puts in Truck Order with Tesla

According to an article in Motor Trend, Wal-Mart Stores Inc., who operate thousands of trucks, said Friday they had reserved Tesla’s truck, which Chief Executive Elon Musk revealed at an event in Hawthorne, Calif., on Thursday. The first highway-ready vehicles aren’t due out until 2019, but the company is taking $5,000 deposits.

The Semi is designed to run up to 500 miles on a single charge, and incorporates Tesla’s semi-autonomous driving system, which the company said could allow big rigs to travel in autonomous convoys with other of its trucks. The company did not provide a sticker price, but said the truck would be cheaper to operate than diesel rivals and could potentially cost less than transport by rail.

Walmart has preordered five units for the U.S. and 10 for its Canadian division, and sees potential for the trucks to help meet company targets for lower emissions, a spokesman said Friday. The company has one of the largest private fleets in the U.S., with some 6,000 trucks. Walmart has tested other new vehicle technology, including diesel-electric hybrid trucks and some that run on liquefied natural gas or other alternative fuels.

The Semi’s 500-mile range on a single charge exceeds what some analysts had expected but could still limit its use on long-haul routes, at least until a nationwide network of charging stations is built. The battery’s weight could also be an issue, as heavier trucks can carry less freight. Tesla says it is planning to build a global network of “megachargers” where truckers could recharge vehicles in about 30 minutes, gaining another 400 miles of range.
