A battery module and a method of assembling a battery module are provided. The method includes selectively applying a light-cure adhesive to recesses in a first side of a carrier layer and inserting battery cells into respective recesses. The method further includes exposing the first side of the carrier layer to light to at least partially cure the light-cure adhesive with the carrier layer in a first orientation, moving the carrier layer into a second orientation, and exposing a second opposite side of the carrier layer to light to fully cure the light-cure adhesive. The recesses may include a sidewall having crush points spaced apart along the sidewall and a bottom portion having an opening between a pair of crush points, where adhesive is not disposed between the pair of crush points.

A separating device for a battery module. The separating device includes a first separating element and a second separating element, which are arranged congruently with respect to one another and adjacent one another. Furthermore, the first separating element and the second separating element enclose a chamber between them, and the chamber is filled with a flame-retarding and/or insulating fluid.

A heat pump system for a vehicle may adjust a temperature of a battery module by use of one chiller that performs heat exchange between a refrigerant and a coolant and improves heating efficiency by use of waste heat generated from an electrical component, including: a cooling apparatus of circulating a coolant in a coolant line to cool at least one electrical component provided in the coolant line; a battery cooling apparatus of circulating the coolant to the battery module; a chiller for heat exchanging the coolant with a refrigerant to control a temperature of the coolant; a heating apparatus that heats an interior of the vehicle using the coolant; and a first, second, third, and fourth connection line.

The invention relates to a supporting housing for a battery compartment of electric drive vehicles by using flat metallic sheets as deep-drawn shells which are fitted into each other whereby at least one double-floor is created into which a passive and partly integrated thermal management system for cooling and heating is integrated. The invention also relates to the integration of further functionality-elements like sensors for status measurement are integrated into the “double-floor” and connected with the battery management system.

An air-conditioning apparatus for an electric vehicle and a method of controlling the same, may include a heat exchanger performing heat exchange between a first fluid and a second fluid while the first fluid and the second fluid flow separately from each other therethrough; a heat source connected to the heat exchanger through a line through which the second fluid flows to allow the second fluid to circulate between the heat exchanger and the heat source, and heating or cooling the second fluid; a circulator imparting a circulation force to the second fluid such that the second fluid circulates between the heat exchanger and the heat source; and a controller determining a required flow rate of the second fluid by use of a flow rate of the first fluid flowing through the heat exchanger and controlling the circulator on the basis of the required flow rate of the second fluid.

A technique is performed on a vehicle having a lithium battery and a temperature control apparatus. The technique involves receiving a temperature reading from temperature sensing circuitry. The technique further involves performing a comparison operation that compares the temperature reading from the temperature sensing circuitry to a target temperature range. The technique further involves, in response to a result of the comparison operation indicating that the temperature reading is outside the target temperature range, automatically providing electric power from an external battery charger to the temperature control apparatus of the vehicle. The external battery charger is distinct and separate from the vehicle. Additionally, the temperature control apparatus adjusts the temperature of the lithium battery of the vehicle in response to the electric power automatically provided from the external battery charger (e.g., heating or cooling the lithium battery to improve battery capacity and preserve battery life).

A rechargeable battery pack includes: a battery housing having an accommodation space; a plurality of cell modules in the accommodation space an having a plurality of unit battery cells connected to each other, and obliquely arranged; a holder part supporting the cell module inside the battery housing; and a bus bar at an upper side of the holder part and connecting electrode terminals of the unit battery cells, wherein the bus bar is between the cell modules at the upper side of the holder, and a lead part connected to the electrode terminal is obliquely protruded from at least one side of the bus bar.

An electrical energy storage device includes prismatic energy storage cells arranged adjacent to one another such that interfaces of adjacent storage cells run at a distance from one another such that the interfaces of the adjacent storage cells form an intermediate space. A respective first layer is arranged between the interfaces of adjacent storage cells, the first layer abutting one of the two interfaces of the adjacent storage cells under pressure. Either the respective first layer also abuts the second of the two interfaces of the adjacent storage cells under pressure, or a second layer is arranged between the interfaces of adjacent storage cells, the second layer abutting the second of the two interfaces of the adjacent storage cells under pressure. A heat-conducting device is arranged in or between the first layer and the second layer is conducted out of the intermediate space between the adjacent storage cells.

A battery module includes a plurality of battery cell assemblies, each having at least one battery cell; a bottom case configured to accommodate the plurality of battery cell assemblies; an upper case mounted to an upper side of the bottom case to expose a part of an upper side, a part of a front side and a part of a rear side of adjacent battery cell assemblies of the plurality of battery cell assemblies; and a cooling unit configured to cover the exposed parts of the adjacent battery cell assemblies and having a phase change material for cooling the adjacent battery cell assemblies.
