发明内容Contents of the invention
依据本发明提出一种电池和具有该电池的机动车。电池包括在隔热外壳中的至少一个电池电芯，其中，在外壳中还设置有电加热元件和恒温器，并且电加热元件和恒温器通过调节器这样相互连接，即，加热元件在冷却到或低于预先规定的最低温度时以这种程度加热，使得最低温度得到保持或重新达到。电池的特征在于，加热元件实施为柔性带。According to the invention, a battery and a motor vehicle with the battery are proposed. The battery comprises at least one battery cell in a thermally insulated housing, wherein an electric heating element and a thermostat are also arranged in the housing and are connected to each other via a regulator in such a way that the heating element cools down to or below a predetermined minimum temperature to such an extent that the minimum temperature is maintained or re-established. The battery is characterized in that the heating element is embodied as a flexible strip.
这样可以使加热元件紧贴地设置在电池电芯上并因此高效地加热电池电芯。This enables the heating element to be arranged snugly on the battery cell and thus to heat the battery cell efficiently.
在一种实施方式中，电池包括至少两个电池电芯并且加热元件至少部分地设置在电池电芯之间。In one embodiment, the battery comprises at least two battery cells and the heating element is arranged at least partially between the battery cells.

加热元件可以由至少一个电池电芯供能。The heating element may be powered by at least one battery cell.
此时，电池的温度管理与外部的充电电源无关。At this time, the temperature management of the battery has nothing to do with the external charging power supply.
在此，可将由至少一个电池电芯的供能限定成在电池未与用于为电池充电的外部电源连接的情况下进行。In this case, the supply of energy by the at least one battery cell can be restricted to take place without the battery being connected to an external power source for charging the battery.

此外，调节器可设计成在通过至少一个电池电芯供给时至少在使用至少一个电池电芯的充电状态的情况下确定加热持续时间。Furthermore, the controller can be designed to determine the heating duration when being supplied by the at least one battery cell, at least using the state of charge of the at least one battery cell.

附图说明Description of drawings
现借助附图和后面的说明对本发明的实施例进行详细说明。其中：Exemplary embodiments of the invention will now be described in detail with the aid of the drawings and the following description. in:
图1示出了依据本发明的电池的一个实施例的外观图；Fig. 1 shows the appearance diagram according to an embodiment of the battery of the present invention;
图2示出了在图1中所示电池的剖面图；以及Figure 2 shows a cross-sectional view of the battery shown in Figure 1; and
图3示出了依据本发明的电池的另一实施例的剖面图。FIG. 3 shows a cross-sectional view of another embodiment of a battery according to the invention.
具体实施方式detailed description
图1示出了依据本发明的电池1的一个实施例的外观图。电池1的外壳具有引线，其实现与电池的电池电芯的电接触。例如，一个电池电芯或多个电池电芯可以连接在高压电网或低压电网上。FIG. 1 shows the appearance of an embodiment of a battery 1 according to the present invention. The housing of the battery 1 has leads which make electrical contact with the battery cells of the battery. For example, a battery cell or a plurality of battery cells can be connected to a high-voltage grid or a low-voltage grid.
图2以剖面图示出了在图1中所示的电池1。在内部中有多个电池电芯3-1...3-n，但唯一的电池电芯也是可行的。在内部中还有用于电子装置和逻辑电路-确切地说调节器4、加热元件6(例如具有正温度系数的也被称为PTC电阻的电阻)和温度传感器7-的区域。电池电芯3-1...3-n设置在由盖板封闭的外壳1-1内，其中，外壳和盖板具有隔热件5。加热元件6在此实施为在电池1的内部中的柔性带。FIG. 2 shows the battery 1 shown in FIG. 1 in a sectional view. There are several battery cells 3-1...3-n in the interior, but single battery cells are also possible. In the interior there are also areas for the electronics and the logic circuit, precisely the regulator 4 , the heating element 6 (for example a resistor with a positive temperature coefficient, also called PTC resistor) and the temperature sensor 7 . The battery cells 3 - 1 . The heating element 6 is here embodied as a flexible strip in the interior of the battery 1 .
在图3中示出了本发明的另一示例性的实施方式。在此加热元件9围绕电池电芯3-1...3-n缠绕并且特别是设置在电池电芯3-1...3-n之间。此外，加热元件可以如该示例中所示的那样分布。A further exemplary embodiment of the invention is shown in FIG. 3 . The heating element 9 is wound around the battery cells 3 - 1 . . . 3 - n and is arranged in particular between the battery cells 3 - 1 . . . 3 - n. Furthermore, the heating elements can be distributed as shown in this example.
对于外界温度降低到最低温度T0以下的情况，通过使加热元件6或9与例如利用PID算法实现的温度调节器8连接将在封装物(Pack)内部中的电池电芯的温度保持成高于最低温度T0。为此受调节地通过调节器8要么从电池电芯、要么从外部的电源向加热元件准确地输送适当的功率。加热元件在此这样安置，即，其热量尽可能仅用于电池电芯，并且尽可能少地丧失其中的热量，而无需加热电池电芯，也就是例如在电池电芯之间的中间。The temperature of the battery cells in the interior of the Pack is kept high by connecting the heating element 6 or 9 with a thermostat 8, for example implemented with a PID algorithm, for the case where the outside temperature drops below the minimum temperature T 0 at the lowest temperature T 0 . For this purpose, the heating element is supplied with precisely the appropriate power via the regulator 8 either from the battery cells or from an external power source. The heating element is arranged in such a way that as far as possible its heat is used only by the battery cells and as little heat is lost therein as possible without heating the battery cells, ie for example in the middle between the battery cells.
因为在也被称为蓄电池组的电池的内部中的材料的热传导能力明显优于隔热件的热传导能力，而且所要求的加热功率相当低，所以加热元件安置在何处并不那么重要。调节器8可集成到蓄电池组的其他的电子控制装置或电池管理系统中。Since the thermal conductivity of the material in the interior of the cells, also called accumulator packs, is considerably better than that of the insulation, and the required heating power is considerably lower, it is not so important where the heating elements are placed. The regulator 8 can be integrated into other electronic control units of the battery pack or into the battery management system.
如果加热元件是PTC电阻，那么该元件可以自动调节温度。If the heating element is a PTC resistor, then the element can automatically adjust the temperature.
对于在工作温度与环境温度之间的所追求的温差必要的加热功率取决于隔热件的厚度和通向电池的电导线的横截面。如果横截面约为250mm2并且厚度约为5cm，那么按照一个实施例一个电池需要100瓦的加热功率，以保证20开尔文的温差。The heating power necessary for the desired temperature difference between the operating temperature and the ambient temperature depends on the thickness of the heat insulation and the cross-section of the electrical lines leading to the battery. If the cross-section is about 250 mm 2 and the thickness is about 5 cm, according to one embodiment a battery requires a heating power of 100 watts to ensure a temperature difference of 20 Kelvin.
在一个实施例中，通过由调节器8或电子控制装置或电池管理系 统防止冷却来避免热量通过在附图中未示出的电池冷却系统而损耗。In one embodiment, heat loss through the battery cooling system, not shown in the figures, is avoided by preventing cooling by the regulator 8 or the electronic control unit or the battery management system.
在车辆没有与充电导线连接的情况下，用于加热元件6的功率可以源自电池电芯3-1...3-n。In the event that the vehicle is not connected to a charging line, the power for the heating element 6 can originate from the battery cells 3 - 1 . . . 3 -n.
此时可为有利的是，在使用电池1的电池电芯3-1...3-n的充电状态的情况下在时间上限制加热持续时间，以防止过度放电。In this case it may be advantageous to limit the duration of the heating in time using the state of charge of the battery cells 3 - 1 . . . 3 - n of the battery 1 in order to prevent excessive discharge.
除了充电状态，可利用外界温度或环境温度和/或驾驶员对停车的持续时间的查询来限制加热持续时间，以防止过度放电。In addition to the state of charge, the duration of the heating can be limited by the outside temperature or ambient temperature and/or the driver's query of the duration of the stop in order to prevent excessive discharge.
