Definitions
- the invention relates to a battery, in particular an electrochemical battery, such.
- a lead-acid battery As a lead-acid battery and a method for producing a battery.
- electrochemical batteries are known, which are used as starter batteries for vehicles. It is well known that the performance and life of such batteries are highly temperature dependent.
- a lead-acid battery has a housing made of an acid-resistant plastic. So far, the trial and small series production frame, the electronic components such as heating, temperature sensors and the electronic control circuit were glued to the battery case. This ensures good heat transfer.
- this adhesive technology requires a lot of effort in the maintenance of individual parameters, such. As the constant composition of the adhesive, the purity of the bond, but also the humidity and the ambient temperature during bonding. If the optimum parameters are not met, the bond may come off. This causes the heat transfer between the film heater and the battery case to deteriorate.
- the battery according to the invention consists of a conventional battery housing, in which the known electrochemical components are arranged.
- a typical battery of this type is a lead-acid battery.
- the battery is surrounded by a heat-insulating housing.
- the material for such a housing consists of a foamed plastic.
- the electronic components are arranged in or on the inside of the heat-insulating housing. This is especially true for the components that must be in thermal contact with the housing, ie, the heater that is provided to heat the battery and the sensors that sense the temperature of the battery housing.
- the invention has a number of advantages, which are also in connection with the process invention according to claim 6 and are therefore described together:
- the cost of attaching the electronic components is low because the material of the heat-insulating housing is sufficiently thick, so that the components are pressed into recesses and thus already held by clamping. It is up to the skilled person to additionally secure the components by means of adhesive, if that should be necessary. Furthermore, the person skilled in the art can select such an insulating material which has the required elastic properties in order to clamp the components securely in the recesses. Another advantage of the invention is that the components can be connected to the insulating material with various highly effective technologies. So it is z. B. possible to use the electronic components by means of a robot to make the wiring also automatically and make the contacting of the lines with the electronic components by means of a soldering robot.
- a resilient intermediate layer is arranged in an advantageous development of the invention according to claim 2 between the material of the heat-insulating housing and the electronic component. This elastic intermediate layer presses the heater and the temperature sensors to the battery case.
- a further improvement of the heat transfer is achieved if according to claim 3 between the electronic components and the housing of the battery an elastic or soft plastic heat conduction layer is provided.
- the method of manufacturing the battery according to claim 1 is claimed, the method comprising the steps of:
- the battery is constructed so that the heater is to be arranged on one longitudinal side of a starter battery and the temperature sensors including the control electronics on the opposite longitudinal side, then the respective insulation plates must be previously equipped with these components and kept ready.
- the insulating parts for the bottom surface and the four side surfaces of the battery form a unit. This means that the bottom surface and the four side surfaces have either been cut together or cut out one at a time and then joined together.
- the parts for the bottom surface and the four side surfaces are connected to each other by means of foil joints.
- These foil joints are particularly necessary when the insulating material is relatively thick and otherwise can not be bent by 90 degrees.
- the preparation of such joints can be done by pressing heated stamp, etc. If, as described above, the individual cut-out insulating parts are adhesively bonded to a self-adhesive film, the desired foil joints also result.
- Fig. 1a and b show cut Isoliermaterialplatten, wherein
- Fig. 1a shows the plate for the bottom surface and the side surfaces
- Fig. 1b the plate for the top of the battery.
- Fig. 2 shows a conventional battery.
- Fig. 3 shows the process steps in the isolation of the battery.
- FIG. 1a shows cut-out insulation material 1 for insulating the bottom 2 and the side surfaces 3 of a battery 4 according to FIG. 2.
- FIG. 1b shows the insulation material 5 for covering the battery.
- Reference numeral 6 denotes a recess for receiving the heater and 7 are recesses for receiving temperature sensors.
- FIGS. 3 a, b show the method step of applying the insulation to the side walls of the battery.
- the portions between the bottom insulation 2 and the side surfaces 3 are formed as joints 8.
- the application of isolation can be done manually or automatically z. B. by means of controllable pressure plates.
- the insulation material 5 can be placed to cover the battery by hand or automatically.
- Fig. 3c shows schematically the completely insulated battery.
- This example of making a battery shows just one of several possibilities.
- the insulation can also consist of 6 individual plates, which are attached by suitable means to the battery.
- the decisive features for the application of the technical teaching according to the invention is that in at least one of these plates a recess for receiving at least one electronic component is provided and this component is arranged in this plate before the plate is attached to the battery.
