Tesla is upgrading its supercharging stations to be the fastest chargers in the world, cutting average charging time down to as little as 15 minutes.

We’ve solved the range problem with electric cars. Now, a single battery charge can go about as far as a single tank of gasoline. However, electric cars still have a problem: it takes maybe 5 minutes to fill up a tank, but as long as an hour to top off a battery.

Not everyone can just take an hour-long pow-wow in the middle of a cross-country road trip. We need a way of getting batteries charged as fast as it takes to fill a tank with gasoline. We’re not quite there yet, but Tesla is getting awfully close.

Unveiled at the Fremont, California plant on Wednesday, Tesla introduced the world to its new 250 kW Version 3.0 supercharger--the fastest charging port on the market. Backed by 1MW power cabinets that ensure that up to 4 electric cars can charge from a single cabinet, these charging stations will provide a Tesla Model 3 Long Range up to 75 miles of range in just 5 minutes.

As a fancy statistic, Tesla said that the hour it took to charge a battery before will now provide the Model 3 with 1,000 miles of range if it only had a battery big enough to store all that juice.

This cuts the average time to charge in half when combined with Tesla’s other big update: On-Route Battery Warmup. This little upgrade starts pre-warming the battery when it notices you’re on the way to a charging station which reduces charge time by 25% from a standard 125 kW charging station.

So on-route warmup plus a beefier 250 kW charger means 50% reduced charging time. Which is cool.

Unfortunately, the 250 kW charger it’s still in beta and won’t be coming around to stations until next year. Fortunately, a slightly boosted 145 kW charger is being rolled out now and should git Tesla’s 12,888 charging stations over the course of 2019.
