One of the biggest drawbacks to electric cars is range anxiety, the worry created by a combination of limited range and long charging times.
More energy-dense batteries are the ultimate solution, but DC fast charging also helps to mitigate that fear. As the name suggests, DC fast charging stations can replenish an electric cars battery pack at a much quicker rate than AC Level 2? charging stations, which typically take between four and seven hours for a full charge.
However, there are a couple of drawbacks. Fast charging puts more stress on the battery, which is why most stations rapidly charge the battery part way (usually up to 80 percent) then slow down dramatically.
DC fast charging is also split among three competing standards, meaning your fast-charging car wont be able to plug into every station. Non-standardised charging is one of the major hurdles facing the electric car industry.
CHAdeMO is preferred by the Asian manufacturers, the Combined Charging Standard (CCS, also known as SAE Combo) is supposed to be used by electric cars from the big US and German manufacturers, and Tesla Motors has gone its own way the Supercharger.
Sound confusing? Heres a rundown of cars available with DC fast charging, the standards they use, and how long it takes to top them off.
