Safety of Li-ion Battery Energy Storage System in the Electric Vehicle Charging Station

DC fast charging station is considered a viable route to facilitate the long-distance travel of electric vehicle along the highway. Installing energy storage system in conjunction with the electric vehicle charging station helps reduce cost by balancing the demand to grid at peak time. With its high energy density and capacity, lithium ion battery has become the choice of many newly installed energy storage system. In this presentation we will discuss the potential hazards associated with the energy storage system and standards applicable to evaluate the safety of the energy storage used in the DC charging station.
