Definitions
- the invention relates to a battery system with at least one fan.
- Batteries for mobile applications usually include a large number of battery cells. These battery cells are limited in terms of voltage and permissible currents. In order to achieve the total voltage and total capacity of the battery required for a given application, the individual battery cells are connected in a certain way. A serial connection increases the required total voltage and a parallel connection increases the required total capacity as well as the permissible total currents.
- each individual battery cell has a certain power loss. This power loss is given off in the form of waste heat in the interior of the battery housing. Since the waste heat can be dissipated to the environment at different locations in the battery, there is an inhomogeneous temperature distribution within a closed one
- the disadvantage here is that the performance of the battery and its lifetime are impaired.
- the individual battery cells can only be operated safely up to a certain temperature. Neither for the loading process nor for the
- the discharge process allows the individual battery cells to exceed this specific temperature in order to ensure the safety of the battery. If the certain temperature is reached by a battery cell during the discharge process, the discharge current of the battery is throttled. If the battery is in charging mode, the charging process is only started if the current temperature of the battery cells is below the specified temperature.
- the battery management system throttles the performance of the entire battery as soon as a battery cell is in the critical range of the limit temperature.
- the disadvantage here is that the battery power is reduced early.
- the operating temperature also plays an important role in the life of a battery cell.
- the aging of a battery cell occurs at high
- Temperature distribution within the closed battery housing ages the battery cells that have a lower operating temperature significantly more slowly than battery cells that have a high operating temperature. Since the battery cells in such a battery cell group are not exchanged or are interchangeable, the entire battery is put out of operation as soon as a certain number of battery cells have reached the end of their life. At this point, however, all other or further battery cells could still be operated safely for a while.
- the document US 2013149583 A1 discloses a battery system with a plurality of electrical cells, a battery housing and a fan.
- a region of the battery housing, which is arranged below the battery cells, comprises an inlet opening for air.
- the side walls and an area of the battery housing above the battery cells have outlet openings for the air.
- Air outlet openings must be inserted into the battery case. Another disadvantage is that the battery case will leak.
- the object of the invention is to overcome these disadvantages.
- a battery system comprises a battery housing with a base body, which has a first cover element and a second cover element.
- the first cover element closes a first open end face of the base body.
- the second cover element closes a second open end face of the
- the battery housing is hermetically sealed from the environment.
- the battery system includes one Battery cell holder, which is arranged within the battery housing and has a plurality of battery cells.
- the battery system shows
- the battery cell holder has at least one cuboid recess, which extends from a third end face of the
- Battery cell holder extends up to a fourth end face of the battery cell holder, the third end face of the battery cell holder being arranged in the direction of the first covering element and the fourth end face of the
- Battery cell holder is arranged in the direction of the second cover element. At least one fan is between the first cover and the
- Battery cell holder is arranged, wherein the at least one fan in
- the advantage here is that the waste heat generated by the operation of the battery cells is homogeneously redistributed within the battery and the homogeneously distributed heat is released through the surface of the housing to the environment, so that the individual battery cells age uniformly and the battery power is only throttled after a longer operating time . That means a medium-fast heating of all battery cells instead of a rapid heating of the battery center and a slow heating in the peripheral areas.
- an improved temperature distribution or rapid cooling of the battery leads to the battery quickly entering a charge-capable state.
- it is advantageous that no openings in the battery housing are required for the inlet and outlet of a cooling fluid.
- neither evaporators nor condensers are required, which means that the overall system is light and inexpensive.
- the battery system is therefore also suitable for small battery applications such as 48V systems.
- the cuboid arrangement is arranged in the middle, starting from the third end face of the battery cell holder, so that central regions of the battery cells are exposed.
- Battery cell holder points in a horizontal median plane of the Battery cell holder a gap, so that the battery cells are held by the battery cell holder only in the upper area and in the lower area of the battery cell. The battery cells are therefore only partially from
- Battery cell holder enclosed. The middle of the battery cells is exposed.
- the at least one fan closes the cuboid recess in the battery cell holder.
- the advantage here is that the warm air can be redistributed efficiently.
- the second cover element has at least one further fan.
- the at least one further fan is arranged on the second cover element within the battery housing.
- the advantage here is that the at least one additional fan is limited only by the size of the second cover element. Large volume flows can therefore be generated.
- the base body is a continuous cast element.
- the battery housing is manufactured in a simple and inexpensive manner.
- the battery housing comprises metal
- Battery housing quickly through the thermally conductive surface of the body to the outside, d. H. outside the battery housing, can be dissipated.
- the use of the battery system according to the invention takes place in an electric vehicle, in particular an electrically operated two-wheeler.
- the vehicle according to the invention in particular an electrically operated two-wheeler, has the battery system according to the invention.
- Figure 1 is a plan view of a temperature distribution
- Figure 2 shows a battery system with at least one fan
- Figure 3 shows the thermal behavior of an inventive
- FIG. 1 shows a top view of an exemplary temperature distribution of a 48 V battery system 100 with a plurality of battery cells 105.
- the battery system comprises thirteen rows of fifteen battery cells 105 each connected in parallel, which form a battery cell group.
- Each Battery cell 105 supplies a voltage of approximately 3.6 V, so that the battery can supply a total voltage of 48 V. Due to the dense arrangement of the battery cells 105, different results result from the waste heat emitted by the individual battery cells during operation of the battery system 100
- first temperature ranges 120 Exemplary in FIG. 1 are first temperature ranges 120 and a second
- Temperature range 121 a third temperature range 122 and fourth
- Temperature ranges 123 shown.
- the first temperature ranges 120 have a lower temperature than the second temperature range 121 and the third temperature range 122.
- the fourth temperature ranges 123 are at
- Battery housings can deliver than the battery cells 105, which are arranged inside the battery cell group.
- the battery management system 109 additionally functions as a heat source.
- FIG. 2 shows a battery system 200 with a battery housing, the one
- the battery housing also has a first cover element that lies opposite the second cover element 203. For reasons of clarity, it is not shown in FIG. 2.
- the first cover element closes a first open end face of the base body 201 and comprises a battery management system, not shown here, the second
- Cover element 203 closes a second open end face of base body 201.
- the battery housing thus forms a closed space which functions as a receiving space for a battery cell holder 204.
- the battery housing is thus sealed from the environment or sealed airtight.
- the battery cell holder 204 comprises receiving areas for a multiplicity of battery cells 205 and has a cuboid-shaped recess which extends from a third end face 207 of the battery cell holder 204 to a fourth end face 208 of the battery cell holder 204, the third end face 207 of the battery cell holder 204 covering the first covering element lies opposite and the fourth end face 208 of the battery cell holder 204 lies opposite the second cover element 203.
- the cuboid recess has, for example, a rectangular one on the third face 207 of the battery cell holder 204 and the fourth face 208 of the battery cell holder 204 Footprint on.
- the center of the battery cell is exposed through the rectangular recess.
- At least one fan 206 is arranged between the first cover element and the battery cell holder 204.
- An arrangement of the fan 206 with respect to the cuboid recess on the third end face 207 of the battery cell holder 204 is particularly advantageous.
- the fan 206 is arranged on the first cover element.
- multiple fans 206 are on the first
- the fan 206 closes the cutout on the third end face 207 of the battery cell holder 204.
- the fan 206 is inserted in the opening of the third end face 207 of the battery cell holder 204 with a precise fit.
- multiple fans 206 are inserted into the recess.
- the recess is rectangular, so that several square fans can be arranged next to and on top of one another in order to
- the fan 206 is larger than the base area of the rectangular recess in the third end face of the battery cell holder 204.
- the battery cell holder 204 does not completely fill the receiving space of the battery housing. This means that the battery housing and the battery cell holder 204 are spaced apart from one another parallel to the end faces. In other words, there are empty spaces or cavities above and below the battery cell holder 204 accommodated in the battery housing. A circulation of the warm air is made possible by the fact that between the first cover element and the battery cell holder 204, as well as between the
- fan 206 can circulate air movement within the
- the air flow represents a pure circulation of the air inside the battery.
- the warm air within the battery is exchanged between areas of high and low temperature, so that the different temperature areas within the battery are equalized.
- the waste heat from the battery cells 205 is redistributed within the battery.
- the battery cell holder 204 can have air channels which are arranged between the individual battery cells 205 in the battery cell holder 204, so that there is an optimal flow around the individual battery cells 205. These air channels can also only be present at the locations of the battery cell holder 204 which the operating temperature of the battery cells 205 is very high, for example in the third temperature range 122 shown in FIG. 1.
- a further fan can be arranged on the second cover element 203.
- Battery case represented by the battery cell holder 204.
- Temperatures within the battery housing are recorded, for example, by means of NTCs at various points in the battery cell network.
- the fan 206 is dependent on the battery management system
- the base body 201 of the battery housing is designed in one piece and tubular and has a metal.
- the metal can comprise aluminum or manganese, for example.
- the base body 201 can be made using a
- the invention can also be used at the module level, the
- Battery cells are to be replaced by battery modules.
- the fan is arranged within the individual battery modules, each of which has its own housing.
- Battery pack level which is the temperature of the individual battery modules
- the battery cell holder must go through a
- Receiving element for battery modules to be replaced or designed such that it can accommodate battery modules.
- FIG. 3 shows the thermal behavior 300 of a battery system with a fan, the volume flows of the fan being different.
- the waste heat from each battery cell is approximately 1.36 W.
- the operating state during a discharge process is shown here, in which a temperature threshold value of 60 ° C. is reached or exceeded for the first time at one point in the battery. This is generally done in one of the centrally located battery cells.
- Figure 3 shows the thermal behavior of those known from Figure 1
- Temperature ranges namely the first temperature ranges 120, the second temperature range 121, the third temperature range 122 and the fourth temperature ranges 123.
- the abscissa represents the individual
- a first curve 301 represents the thermal behavior of the battery without a fan.
- a second curve 302 shows the thermal behavior of the battery with a fan that has a volume flow of 0.72 m 3 / h. The course of the curve of the second curve 302 in the temperature ranges 120 and 121 can be explained by the fact that the edge areas have already warmed up due to the low volume flow of the fan when the battery center is at 60 ° C.
- a third curve 303 shows the thermal behavior of the battery with a fan which has a volume flow of 4.6 m 3 / h and a fourth curve 304 shows the thermal behavior of the battery with a fan which has a volume flow of 9.6 m 3 / h.
