We reported earlier that Tesla Motors had developed a battery swap technology that allowed dropping a new battery into the vehicles in just 90 seconds. Now the engineers at Tesla think they can drop the battery charging time down to just five minutes.
Last September, Tesla announced a network of "supercharging stations" that were design exclusively for the S model cars that would recharge the battery in as little as thirty minutes. Then in May, they announced that they had been able to drop the time to only twenty minutes.
Now Tesla's Chief Technology Officer, JB Straubel, says that they are continuing work on reducing battery charging time and thinks that in a few years they can get the charge time down to 5 or 10 minutes.
"It's not going to happen in a year from now. It's going to be hard. But I think we can get down to five to 10 minutes," Straubel said in an interview with MIT Technology Review. He noted that the current superchargers, which deliver 120 kilowatts of electricity, "seemed pretty crazy even 10 years ago." Conventional public charging stations deliver well under 10 kilowatts.
The fast charging technology will only work on Tesla vehicles at Tesla charging stations, but the advancements into charging technology will eventually hit the other automakers and help promote the viability of electric vehicles.
