1. Battery recharge time DESCRIPTION
Slow conventional rechargeable battery to full power for about 7-8 hours, so the choice of many owners or night electricity for the car charging trough. When you need a very short period of time the battery is fully charged, it seemed normal charging mode “stretched”, and at this time, is the debut of the fast charge time. Generally refers to fast charge the battery in a relatively short period of time at or near A charging method for the fully charged state. And compared to conventional cars, electric vehicle charging time is generally longer length of the defect. Fast Charge special equipment requirements, the charging time to reach an internal combustion engine fuel filling degree of temporal proximity. Although the cost compared to conventional charging methods to be high, but therefore this research technique has great application value and practical significance. Electric vehicle charging station to use more quickly to shorten the art electric vehicle charging time, rapid charging techniques including pulse charging method, 2REFLEXTM fast charging method, alternating current intermittent charging method, variable voltage intermittent charging method, variable alternating current voltage waves batch plus or minus zero pulse fast charge method. While various specific techniques, but the principles are generally high charge current to the battery in a short time. But note that not all electric cars can be fast charging, this is due to the fast charging, the battery will withstand a short time high current “shock”, thus causing ordinary batteries overheating, there are security risks. Thus, the vehicle early stage of development, need to select a special battery for fast charging, of course, in any case optimize battery, fast charging will start both the performance and battery life have an impact.
