NOVELTY - The system has thermally managed battery cells whose battery matrices (A) connected to a grid power through bi-directional power electronic devices (B) i.e. Inverters. A battery control and management system (C) includes a control algorithm and sensing units for controlling charge or discharge of the battery based on grid command or internal battery management system control algorithms. The electrical energy stored in the battery cells flows through DC charging interface devices and charge ports (D) to charge up multiple electric vehicles (EV) at the same time.    USE - Grid optimizing direct current (DC) charge system for use as a DC to DC charge station to provide electrical energy to electric vehicles, and as an effective power factor correction device to improve the grid efficiency, and for facilitating system Regulation for bi-directional power electronic devices, for storing electrical energy from renewable energy generating sources such as windmills, solar panels, and for providing uninterrupted backup power to critical facilities and emergency services during power outage.    ADVANTAGE - The system uses energy stored in battery to provide DC fast charge to electric vehicles while functioning as a grid load leveling energy source and frequency regulating device. The system uses a battery matrix as a multi-purpose energy source for the large scale adoption of electric vehicles by providing DC fast charge services at a very high charge rate and to enable power plants to operate more efficiently and emit less pollution by running at a constant optimized power output, thus reducing the associated emissions of Carbon dioxide (C02), Sulfur dioxide (S02), and nitrogen oxides (NOx). The battery management system ensures that the battery matrices function under optimal conditions through temperature control, cell balancing, and state of charge management, thus managing the data communication between the charge station and power grid, and commanding the safety system of the battery matrices. The system shapes the charging load dynamically according to grid needs for efficiency optimization.
