A supercharging tweak from Hyundai could fill an electric car battery to ninety percent in 10 minutes. The new algorithm uses artificial intelligence to ramp up and reduce voltage and current sequentially while maintaining battery health. The technique could be used on any standard electric car battery and could fill the battery in 10 minutes. It could also increase battery life. The new algorithm is being tested by companies including Hyundai and Tesla.
Tesla’s early high peak of charging power is a smart strategy
The charging power of a Tesla Model S is front-loaded, meaning that it reaches its peak power in the early part of the charge. This strategy is highly efficient, as it provides added range while minimizing battery degradation. Non-Tesla EVs, on the other hand, spend the majority of their charge cycle at power levels that are limited by their charging hardware. In addition, pack voltage cannot be increased post-hoc. Consequently, recharging the battery will raise the pack voltage to its maximum potential difference.
A similar strategy could be implemented for charging other electric vehicles. A bidirectional system would allow a Tesla to provide power to another electric vehicle. This would reduce peak demand and make electric utilities happy. Using this model, Tesla would sell access to its network to electric utilities. This would allow the electric utility to use the vehicle’s energy as a resource and reduce their demand on the grid.
Hyundai’s supercharging tweak could fill electric car batteries 90% in 10 mins
Unlike internal combustion vehicles, electric cars require fewer maintenance tasks. Hyundai offers five tips for extending battery life, from preventing it from discharging too low to making sure you always have a full charge. The automaker also recommends charging the car frequently, every two to three days, to prevent the battery from degrading too quickly. In addition to regular charging, you’ll also need to charge the car when you plan to make long journeys.
Supercharging is a technique in which a car’s battery is charged quickly. The faster the charger is able to recharge the battery, the less time it will take. While most automakers use liquid cooling to keep the battery temperature low, this approach can leave a buffer, resulting in a difference in the driver’s perception of battery capacity. As a result, Hyundai says its supercharging tweak could fill an electric car’s battery 90 percent in 10 minutes. The tweak is a big deal for the automaker.
StoreDot’s “extremely fast-charging” battery technology
According to an Israeli startup called StoreDot, its new battery technology could fill electric car batteries by 90% within 10 minutes. The company says that it has already produced 4680 battery cells with its new technology and is dispatching them to global automakers for testing. Despite the company’s adamant refusal to name any automakers, it’s hard to imagine any automaker not taking this promising new technology seriously.
Tesla’s relaxed its upper buffer on the battery charging limit
The EPA hasn’t been happy with the Tesla drivers’ complaints about range, so the company has eased its upper buffer on battery charging limits. In the manuals, owners are warned to not drive the car down to 0 percent charge, but the car has been getting a range boost after the upgrade. And Tesla’s engineers weighed in, saying that the safety buffer is bad for the battery.
The 80% charge point is where the Bolt has a problem, but charging the car to this level should solve that. The 7kW charger does not slow the charging process. This is because the charging rate is already slow compared to the battery capacity. However, Tesla has also relaxed its upper buffer on battery charging limits. The EV should still be charged to 100% when parked and driven as usual.
