摘要： A cooling system for a battery pack in a vehicle comprises a base plate, a plurality of transverse members, a pump, a controller, and a heat exchanger. The controller causes the pump to generate fluid flow into an inlet/outlet port of the base plate. The base plate comprises a channel with segments for supplying fluid to a first set of fluid distribution ports and receiving fluid from a second set of fluid distribution ports. Each fluid distribution port is in fluid communication with a main conduit of a transverse member and transverse conduits connect the main conduits of a transverse member. Fluid flow through the channel in the base plate and the main conduits and transverse conduits of the transverse members cool the batteries and distribute heat. Cooling multiple sides of the batteries reduces the operating temperature to reduce charging times and extend the service life of the batteries.

摘要： A vehicle battery module includes battery cells and a plurality of cooling tubes, each provided to correspond to one of the battery cells and disposed either above or below, or both above and below the corresponding one of the battery cells. The battery module includes connectors each connecting one of the battery cells to a corresponding one of the cooling tubes so as to cool the battery cell through the cooling tube. A cartridge is configured to fix positions of the plurality of cooling tubes and a case is coupled to outer sides of the battery cells in a state in which the battery cells, the connectors, and the cartridge are assembled. A cooling pipe is connected to the plurality of cooling tubes so as to supply a cooling medium to each of the cooling tubes.

摘要： A method monitors the functional capability of the cooling system of an operating high-voltage accumulator for an electric drive unit of a motor vehicle. The method repeatedly measures the temperature of the high-voltage accumulator by use of a temperature sensor mounted on the high-voltage accumulator; checks whether the measured temperature value is above a cooling threshold temperature; determines a profile of the temperature of the high-voltage accumulator using a temporal sequence of the measured temperature values of the high-voltage accumulator which are above the cooling threshold temperature; and diagnoses that the cooling system is operating correctly if the temperature profile does not exceed a predetermined threshold.

摘要： A method for producing a traction battery of a motor vehicle. A battery housing of the traction battery has a receptacle for receiving a cell module. It is provided that support surfaces for supporting the cell module spaced apart from a bottom of the battery housing are formed on walls of the battery housing delimiting the receptacle compartment, and that a distance between the support surfaces and the base is measured, an amount of heat conducting calculated from the distance is applied to the bottom, and then the cell module is inserted into the receptacle compartment supported on the support surfaces.

摘要： The battery cooling structure includes a cell stacked body that has an inter-cell flow path between adjacent battery cells, a base plate that is disposed adjacent to one of surfaces of the cell stacked body, an inflow-side flow path that is disposed between the cell stacked body and the base plate and communicates with the inter-cell flow path, and an air supply port that is disposed in one end portion of the inflow-side flow path in the stacking direction and supplies air to the inflow-side flow path are included. The base plate has a branching portion that branches air in the inflow-side flow path, into a plurality of flows, and the branching portion is disposed at a position that is further from the air supply port than one endmost battery cell of the cell stacked body, the one endmost battery cell being adjacent to of the air supply port.
