Abstract: Systems, methods, devices, and apparatuses associate with energy storage are provided. An apparatus can include a battery block with battery cells disposed therein. The apparatus can include an integrated current collector to electrically couple the battery cells in parallel. The integrated current collector can have a first conductive layer to connect with first polarity terminals of the battery cells, a second conductive layer to connect with second polarity terminals of the battery cells, and a circuit board layer parallel to the two conductive layers. The apparatus can include trace lines each formed on the circuit board layer and connected to the two conductive layers. The apparatus can include a battery monitoring unit (BMU) incorporated on the circuit board layer. The BMU can have inputs coupled with the two conductive layers to obtain a signal indicative of a characteristic of the battery block.

Abstract: Apparatuses, systems, and methods of controlling of an energy storage unit are detailed herein. A cold plate can be thermally coupled with an energy storage unit for powering the electric vehicle. The cold plate can have a bottom layer. The bottom layer can have a channel spanning across a top surface of the bottom layer to circulate coolant to transfer heat away from the energy storage unit. The top layer can be flush with a bottom surface of the energy storage unit. The top layer can define openings each extending between the top surface and the bottom surface. The cold plate can have inserts sealing the openings. The inserts can have a melting temperature lower than a melting temperature of the top layer to expose at least one opening when heated the melting temperature to allow release of the coolant from the channel onto the energy storage unit.

Abstract: Systems and methods of controlling temperature in energy storage units. The system can include energy storage units disposed in an electric vehicle. The system can include cold plates disposed in the electric vehicle. Each cold plate can be thermally coupled with an energy storage unit to transfer heat using a coolant. Each cold plate can have an inlet to receive the coolant from an inlet manifold, an outlet to release liquid to an outlet manifold, and a control valve coupled to at least one of the inlet and the outlet. The system can include a battery management system (BMS) connected with the energy storage units. The BMS can determine, for each cold plate, a target flow rate for the coolant using a characteristic of the energy storage unit. The BMS can send, to each cold plate, a signal to control the control valve in accordance with the target flow rate.
