Background
With the continuous enhancement of environmental awareness of people, the demand for environment-friendly new energy vehicles is increased, and various large automobile manufacturers vigorously develop gasoline-electric hybrid vehicles and pure electric vehicles. In the development process of new energy automobiles, electric appliances which directly utilize a high-voltage (hundreds of volts) power battery for power supply are increasing continuously; the battery distribution unit BDU, which is closely related thereto, serves, among other things, primarily as a switch for interfacing the power battery system with the outside world, for disconnecting the power battery system of the vehicle at a suitable time, and for distributing electrical energy.
Many electric vehicles on the market are on fire during operation, mostly because the batteries are overheated. On the one hand, the requirements of users on the safety of automobiles are increasing; on the other hand, the power performance of electric vehicles is increasing, and the current flowing through the BDU is also increasing. Therefore, when the resistance of components such as relays and fuses in the BDU cannot be further reduced, the amount of heat generated by the BDU increases as the operating time of the automobile increases. At this time, if the temperature of the BDU cannot be effectively controlled, an excessively high temperature may cause, for example, melting of part of electronic parts, and further cause short-circuiting of the power battery, thereby causing a serious safety hazard.

In the drawings:
fig. 1 is a schematic diagram of a battery distribution unit 100 according to an embodiment of the present invention.
Detailed Description
In this specification, the invention is described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown. This invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. The embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Words such as "comprising" and "comprises" mean that, in addition to having elements or steps which are directly and unequivocally stated in the description and the claims, the solution of the invention does not exclude other elements or steps which are not directly or unequivocally stated. Terms such as "first" and "second" do not denote an order of the elements in time, space, size, etc., but rather are used to distinguish one element from another.
Referring now to fig. 1, fig. 1 is a schematic diagram of a battery distribution unit 100 according to an embodiment of the present invention. The battery distribution unit 100 includes: a temperature sensor 110, a heat conductive material 120, an insulating material 130, a water cooling device 140, and a controller 150.
Wherein the temperature sensor 110 is selectively placed at one or more components in the battery dispensing unit 100. The components may typically include relays, fuses, and the like. In fig. 1, three relay assemblies (relay 1, relay 2, and relay 3) and one fuse assembly are shown by way of example. In selecting the location of the temperature sensor 110, measurements may be taken of the battery distribution unit of an existing vehicle to obtain temperature profiles of various components in the battery distribution unit under various operating conditions of the vehicle, including rapid acceleration, rapid deceleration, vehicle charging, vehicle discharging, and the like. Therefore, the components which are expected to be monitored in the battery distribution unit of the vehicle can be monitored in real time, and the real-time temperature of the components is controlled, so that part of the components are prevented from being melted or damaged in other ways due to overhigh temperature, and the safety of the whole vehicle is critical. The sensors may then be placed at one or more of the components that are the highest in temperature compared to the other components. For example, two temperature sensors 110-1 and 110-2 may be placed at the two components with the highest temperatures during vehicle charging and discharging, respectively (e.g., at the high voltage terminals of relay 1 and relay 3 of FIG. 1).
The thermally conductive material 120 may be thermally conductively coupled to one or more components. Which absorbs heat from the components to be cooled and subsequently transfers it to the water cooling device 140. According to the embodiment shown in fig. 1, the thermally conductive material 120 may be in the form of a thermally conductive glue or pad that is attached to the terminals of one or more components.
The water cooling device 140 may be connected with the heat conductive material 120 through the insulating material 130. In the embodiment shown in fig. 1, the insulating material 130 may have the form of an insulating film that is attached to the water cooling device 140 to isolate the component from the water cooling device 140. The water cooling device 140 may have the form of a water cooling plate, but it may also have various forms capable of achieving the object of the present invention, as needed. In one embodiment, the water cooling apparatus 140 may be connected in series to a water cooling system of the vehicle. Therefore, heat can be taken away from the heating component through the circulating water path of the whole vehicle, and the temperature of the component is reduced to a certain degree. In another embodiment, the water cooling device 140 may be provided at a position where the water flow in the water cooling system finally passes, i.e., a water flow outlet position.
The controller 150 controls the water cooling device 140 in response to a signal from the temperature sensor 110, which indicates the temperature of one or more components in which the temperature sensor 110 is installed. Specifically, the controller 150 may be configured to activate the water cooling device 140 if the temperature of one or more components is above a preset temperature threshold. For example, the water cooling apparatus 140 is activated whenever the temperature of any of the one or more components is above a preset temperature threshold. Alternatively, a plurality of temperature thresholds are preset for one or more components, and the water cooling device 140 is controlled to be activated as long as the temperature of any one of the components mounted with the temperature sensor 110 is higher than the corresponding temperature threshold. The controller 150 may be a controller dedicated to controlling the water cooling device 140, may be a controller dedicated to controlling the battery distribution unit BDU, or may be part of an Electronic Control Unit (ECU) of the vehicle. In connection, the controller 150 may be directly or indirectly connected to the water cooling device 140 in various ways to achieve the effect that the water cooling device 140 can be controlled.
In the embodiment of fig. 1, the structure is designed such that the terminals of the respective components are on the same plane with the copper busbar 160 (which may be on one side of the copper busbar 160), and then the copper busbar is coated with a thermal conductive paste or attached with a thermal conductive pad. The water cooling device 140 (e.g., a water cooling plate) is then subjected to an insulation process (e.g., an insulating film is attached), and the insulated side and the copper bar are attached together.
The battery dispensing unit 100 also includes a copper conductive bar 160 that connects the terminals of one or more components and that is connected to the thermally conductive material 120. For example, in the embodiment of fig. 1, the copper conductive bar 160, the heat conductive material 120, the insulating material 130, and the water cooling device 140 may be sequentially disposed in this order on one side of the component.
According to a second aspect of the invention, there is also provided a vehicle comprising a battery distribution unit 100 according to the description hereinbefore. The vehicle can effectively control the temperature of the battery distribution unit 100 under the condition of current increase in the vehicle, and prevent devices from being damaged due to overhigh temperature and a series of faults and safety problems caused by the damage. The battery distribution unit 100 according to the invention is particularly suitable for vehicles provided with a plurality of high-voltage consumers, such as motor controllers, on-board chargers, air-conditioning compressors, etc., among other things.
According to a third aspect of the present invention there is provided a method of controlling the temperature of a battery dispensing unit using a battery dispensing unit according to the first aspect of the present invention. In one embodiment, prior to use of the battery dispensing unit according to the first aspect of the invention, analysis is also performed using a Computer Aided Engineering (CAE) analysis method, and the battery dispensing unit according to the first aspect of the invention is used in case cooling is required according to the analysis result. Analyzing the temperature of the battery distribution unit using the CAE analysis method makes it possible to analyze whether there is a risk of failure due to overheating according to the temperature limit conditions of the respective sub-parts, and thus selectively use the battery distribution unit according to the first aspect of the present invention. Specifically, the method includes measuring a temperature at one or more components in the battery dispensing unit using a temperature sensor; and controlling the water cooling device in the battery distribution unit according to the first aspect of the invention in response to a signal from the temperature sensor. Wherein, control water cooling plant includes: the water cooling means is activated in case the signal from the temperature sensor indicates that the temperature at the one or more components is above a preset temperature threshold.
