Many User for the operation of electric vehicles is still a vague concept, to the charging station is charging how? Why is an electrical plug to charge a couple of hours, much slower than refueling, will not cause congestion charging stations? Beijing Institute of Technology, Vice President, National Engineering Laboratory, director of electric vehicles Feng-Chun Sun a few days ago In an interview with People’s Network User puzzled when an interview subject had to answer.
He said there are a variety of electric vehicles, one battery-powered car called the pure electric vehicles, as well as hybrid cars, hybrid cars, in many cases does not require recharging, it is to solve this problem. There are also fuel cell vehicles, is by adding hydrogen. Pure electric cars are charging, charging the former there are two kinds: one is to stop charging, charging at night because of cheaper electricity at night charging, therefore, low electricity cheaper, with today’s technology VGP-BPS9/B , VGP-BPS9A , VGP-BPS9A/B , it should be between three and four hours, but there are filling fast, but fast-charge, then it will affect battery life.
Another is that public transport, it is impossible to stop and charge four hours of electricity, because electric vehicles inside the heart is motor, do not drink out of oil, is burned electricity, batteries to provide it with electricity, the battery is over, for example to open a dedicated replace the battery station, the buses to run out of batteries from the battery to take down on the charging station, charging stations to charge a good battery and then put on the automatic replacement of electric vehicles, five minutes or so put a car battery for over, can continue to run, this does not affect the use of vehicles. Replaced the battery in the battery rack, with charging station charging inside the charger, making it very economical, very smoothly filled. The so-called electric car infrastructure mainly refers to the charge, or replace the battery of this power plant.
So how to ensure Paochang Tu electric cars do? Feng-Chun Sun said that if Paozhang Tu, running more than 1000 kilometers, it must be this model; as now the same as for gas cylinders, gas cylinders to the gas station you put it to you for one tank, gas cylinders and batteries may be the shape of shape of the package is not the same as the future of the battery pack is a package, you are simply discarded, for walking on it. Foreign stations generally replace the Sony VGP-BPS9/S battery , just as many gas stations are now bottled oil, took left are the same. Therefore, the User to worry about.
