Ultra fast charging system on lithium ion battery

Even with the advancement of the high technology nowadays, the popularity of electric vehicle is still limited and unable to make it a common usage. The main reason is due to the limitation of the battery pack which is bulky, heavy, slow charging, short lifespan and toxicity hazardous. Among these problems, slow charging speed becomes the main consideration when purchasing an electric vehicle. Hence, different charging methods have to be studied thoroughly to seek for the best solution to overcome these problems. In today's competitive battery charging method, a lot of charger manufacturers claim that they can amazingly short charge times of 30 minutes or less. In this project, different charging method such as Constant Voltage charging, Constant Current charging, Pulsed charge etc, have been studied and compared to optimize the charging time suitable for different kind of battery pack.
