Abstract: A battery electric device includes a battery cell, e.g., a pouch, prismatic, or cylindrical cell, connectable to an electric load, and a direct-to-air thermoelectric assembly (TEA) or another heat pump connected to a surface of the cell. A pressure control device maintains constant pressure on the cell surface when the cell is connected to the load. Connection to the load causes the TEA/heat pump to pump heat from the cell. A sensor, e.g., thermocouple(s) and/or heat flux sensor(s), generate an output voltage signal indicative of the quantity of heat. A battery system includes the device and a processor in communication with the cell, the load, and the power supply. The processor generates an electronic control signal in response to the quantity of heat.

Abstract: A system and method for rapid lithium ion battery charging are provided. The method for rapid charging a lithium ion battery may include generating a reduced order electrochemical model (ROM) of the lithium ion battery in which a state-of-charge (SOC) model, a side reaction model and a degradation model are embedded. The method may further include calculating an SOC, a side reaction rate, and a lithium plating rate from the ROM. The method may further include generating a charging protocol based on the SOC and a required SOC, and applying the charging protocol to the lithium ion battery.

Abstract: A charging apparatus includes a control unit configured to determine an average ion concentration, a surface ion concentration and a solid phase potential for anode particles and an electrolyte potential in an anode, using a predefined electrochemical reduced order model. The control unit is further configured to determine a side reaction rate from the solid phase potential and the electrolyte potential. The control unit is further configured to reduce the magnitude of the charging current applied to a secondary battery based on at least one of a cutoff voltage, the surface ion concentration and the side reaction rate.
