Definitions
- the invention relates to a device with a carrier having an opening for receiving a battery cell on the shell side, which has a measuring channel for a measuring head extending between an outer wall of the carrier and the opening, which has a locking mechanism for a measuring position set against the battery cell shell.
- Battery cells are a basic requirement for carrying out fundamental processes in the field of electromobility, such as determining the state of charge of the battery module and adjusting the optimal
- battery modules are known that accommodate battery cells and have temperature, voltage and humidity sensors
- Battery module and in the battery cells which reduces their service life, performance and operational reliability.
- the invention is therefore based on the object of an inhomogeneous distribution of the state variables within a battery module and within a
- the invention solves the problem in that the measuring head has a
- the battery cell can be easily inserted into the opening and aligned with the carrier without a measuring head being withdrawn into the measuring channel or completely removed from it Damage to the measuring head is also to be feared during industrial joining processes.
- the measuring channel remains accessible via the outer wall of the carrier, so that the measuring head is inserted and attached to the battery cell after joining Battery cell casing can be positioned in a predefined measurement position so that, for example, a galvanic contact or a good
- the measuring channel preferably runs transversely to a longitudinal axis of the battery cell within the carrier. If several openings for several individual battery cells are provided on a carrier according to the invention, several measuring channels can be provided for at least some of these battery cells so that inhomogeneous state variables within a battery module with one
- the carrier according to the invention can be detected.
- the measurement of the state variables can take place at different positions on the battery cell casing, so that positions representative of the state variables can be selected for the measurement.
- the measuring head can be fixed by means of a locking device, for example designed as a latching connection.
- This locking device can also be designed to be detachable for maintenance or for the replacement of a defective measuring head.
- Signal lines for the measuring head are routed to the outside.
- the measuring head made of plastic, the measuring head can be in a measuring position
- Alignment can also be done using several locking springs or
- Locking stops may be provided. Particularly advantageous conditions arise when the measuring head has, on its end section facing away from the battery cell, a cover plate that closes off the measuring channel towards the outer wall of the carrier.
- This cover plate can have a passage opening for releasing the detent spring.
- the cover plate can comprise a further passage opening or a connection socket for a signal line leading to the sensors.
- Battery cells form two electrical poles, which are usually accessible as electrical contact points at predefined positions.
- one pole forms the battery cell jacket, which makes handling easier
- the measuring head has a galvanic contact point of a voltage sensor which, in the measuring position, rests against the battery cell jacket forming an electrical pole.
- Battery cell casing is electrically insulated, it can be peeled or stripped before joining at least in the area of the measuring channel opening into the opening, so that a pole can be contacted via the battery casing.
- An electrical contact can be established between the voltmeter and the battery cell casing as a pole via the galvanic contact point of the measuring head, because the galvanic contact point rests against the battery cell casing in the measuring position and enables the voltage to be picked up.
- the measuring head includes a deformation sensor for measuring a jacket-side expansion of the battery cell. This is because it has been shown that critical operating conditions can be identified at an early stage by means of minor deformations of the battery cell. Such deformations are particularly evident in battery cells with a wound electrode core
- Battery cell casing can be determined, so that especially a casing-side tap a allows early error detection.
- the deformation sensor can be a strain gage attached to the measuring head at a suitable point, possibly pretensioned.
- the battery cell is floating within the opening, for example by means of seals.
- the position of the battery cell relative to the carrier within the opening changes during operation. Therefore, in order to enable reliable measurements regardless of the relative position of the battery cell to the carrier within the opening
- the measuring head forms a clamp which partially encompasses the battery cell casing in the measuring position. Because the clamp partially encompasses the battery cell casing, relative movements between the measuring head and the battery cell are avoided.
- the clamp offers the possibility of attaching different sensors to several measuring points, whereby the non-positive clamping connection along the clamp arms, in particular in the area of the free end sections, results in matching measurement conditions.
- a deformation sensor such as, for example, can be used in the area of the fork of the clamping arms
- Strain gauges are attached. These measurement conditions can be further improved if there is not only a force fit but also a form fit between the terminal and the battery cell, in that the clamping arms have the largest diameter of the battery cell starting from the mouth of the
- the clamp can form the locking mechanism for the measuring head.
- the clamp can form the locking mechanism for the measuring head.
- the clamp supplements one provided in the measuring channel
- the in Measuring position of the battery cell jacket facing end portion of the measuring head forms a fastening portion for a flexible sensor carrier.
- the sensor carrier can be the same for different, different battery cell geometries, because it is adapted to a specific battery cell geometry via the shape of the fastening section of the measuring head.
- This fastening section can be opposite a stop surface of the
- End section be set back so that a sufficient height for the individual sensors is achieved.
- Fastening section and the stop surface can be along the
- Fastening section a groove running along the end section, wherein the groove base can have elevations and / or depressions.
- Execution of the measuring head and the sensor carrier as two components can also increase the areas of application of the measuring heads by prefabricating the sensor carriers with sensors for different state variables at different positions on the sensor carrier and then placing them on the measuring head.
- a particularly dynamic control behavior in particular for the temperature of the battery cells, can be achieved in that a cooling fluid flows directly against the battery cells.
- a detection of the state variables with a slight time delay and preferably directly in the area of the battery cells exposed to the flow is required.
- the invention therefore also relates to the fact that the carrier delimits a fluid flow channel through which the battery cell passes and that a seal is located downstream of the measuring channel mouth in the opening in the direction of the fluid flow channel.
- both the seal against the fluid flow channel between the battery cell casing and the carrier and the measurement of the state variables on the battery cell casing can be accommodated within the carrier immediately following this seal, so that not only does a particularly compact design result, but also the measuring point can be arranged in the immediate vicinity of the fluid flow channel and thus the area of the battery cell jacket where the fluid flows.
- the device can be exposed to vibrations or other mechanical stress during operation.
- mechanical stresses can arise that stress sensitive parts of the device, such as soldered electrical contacts.
- a temperature sensor be used
- entropy elastic buffer is attached to the measuring head. This enables mechanical forces that occur to be directed into the entropy-elastic buffer, which is reversibly and non-destructively deformed. This avoids these forces being directed into more sensitive parts of the device and possibly damaging them in the process.
- the entropy elastic buffer prevents unintentional electrical contact between the battery cell and the measuring head due to its insulating properties. In this case, of course, the temperature sensor must have a corresponding heat-conducting insulation with respect to the battery cell jacket.
- the entropy-elastic buffer can be biased so that the temperature sensor is pressed against the battery cell jacket, so that there is always a reliable contact between the battery cells even in the event of vibrations or other mechanical influences
- Entropy elastic buffers can be made of rubber, for example.
- the measuring head is in contact with a circuit board via contact pins so as to be displaceable in the direction of the measuring channel.
- the board carries the ones emanating from the measuring head
- Battery state variables can be avoided if a plug receptacle for the contact pins is provided on the side of the board opposite the measuring channel.
- the connector receptacle surrounds the contact pins and prevents both mechanical damage to the contact pins and unintentional electrical contacts between the contact pins and any conductive components that may be present in the immediate vicinity of the device.
- a pin strip and a socket strip are provided, which are electrically connected to the measuring head via signal lines.
- Adjacent devices for example a battery stack, can be easily and reversibly detachably connected to one another via the pin and socket strips, so that cable lines and installation space can be saved and the measured state variables can be read out via a central output and / or a bus system.
- Show it 1 shows a section of a device according to the invention with inserted
- FIG. 2 shows a section along the line II-II in FIGS.
- FIG. 3 shows a section, corresponding to FIG. 1, of a further embodiment
- a device has an opening 1 for receiving battery cells 2 on the shell side in a carrier 3.
- the carrier comprises a measuring channel 5 extending between the outer carrier wall 4 and opening 1.
- a measuring head 6 is inserted into this measuring channel 5 and fastened by means of a locking device so that it can be positioned against the battery cell casing 7. As a result, the measuring head 6 can only be inserted into the measuring channel 5 after the battery cell 2 has been inserted into the opening 1, so that the measuring head 6 does not hinder the joining process.
- the measuring head 6 can be locked in the measuring position in the measuring channel 5 via a locking stop 8, which is engaged from behind by a locking spring 9 attached to the measuring head 6.
- the latching stop 8 can be part of the carrier outer wall 4.
- the measuring channel 5 is opened via the detent spring 9 on the detent stop 8
- the form fit of the cover plate 10 with the carrier outer wall 4 enables a visual inspection when the detent spring 9 is engaged with the detent stop 8 whether the measuring head 6 has reached the predefined measuring position.
- the cover plate 10 can also have openings for releasing the detent spring 9, or for
- Signal lines 1 1, which lead to the sensors on the measuring head 6, include.
- the measuring head 6 has a galvanic contact point 12 of a voltage sensor, which contacts the battery cell jacket 7 as soon as the measuring head 6 has been locked in the measuring position.
- the measuring head 6 can comprise several different sensors, such as one
- Deformation sensor 13 for measuring the shell-side expansion of the
- Measuring head 6 can be adapted to the circumstances and prevailing geometries. In the case of conventional cylindrical battery cells 2, the measuring head 6 can form a clamp which grips around the battery cell in a non-positive manner and, depending on the embodiment, also positively. By a suitable choice of the material, such as plastic, for the measuring head 6, geometries adapted to the battery cell shape can be easily implemented in terms of production technology. Instead of being attached directly to the measuring head 6, the sensors can be attached to a flexible sensor carrier 15. The sensor carrier 15 is subsequently on a
- This fastening section 16 is designed in such a way that, for example, by local elevations,
- the fastening section 16 can also form a groove running along the end section of the measuring head 6 facing the battery cell 2, the groove bottom of which has corresponding elevations and depressions in order to optimize the contact and measuring conditions with regard to the different sizes and shapes of the sensors.
- the device according to the invention can also be used with fluid-cooled battery cells 2, with the opening of the measuring channel 5 in the direction of a fluid flow channel 17 being followed by a seal 18 to establish a flow connection between the electrically conductive components of the measuring head 6 and the fluid channel 17 to prevent.
- 3 shows an embodiment of the device according to the invention in which the measuring head 6 has a temperature sensor 19 for contacting the battery cell 2 on the casing side in the measuring position and the temperature sensor 19 is attached to the measuring head 6 via an entropy-elastic buffer 20.
- Entropy elastic buffer 20 prevents unintentional electrical contacts between the battery cell 2 and the battery cell 2 due to its insulating properties
- the temperature sensor 19 can be pressed against the battery cell casing 7. This increases the reliability of the temperature measurement in the event of disruptive mechanical vibrations.
- the signal lines 11 can be routed over a common circuit board 22, with the temperature sensor 19 being able to be mounted displaceably in the direction of the measuring channel 5 via contact pins 21 and be electrically connected to the measuring head 6. This allows rigid connections, such as
- the ends of the contact pins 21 can be electrically shielded from the surroundings of the device by means of a plug receptacle 23, whereby, for example, short circuits or the incorrect reading of the battery state variables can be avoided.
