POLISH INTEGRATED STARTING CURRENT LIMITER

Description

[0001] The subject matter relates to a starting current limiting system, in particular for motor vehicles with an internal combustion engine, comprising at least a first electrical connection part connectable to a battery pole, a second electrical connection part connectable to a starter, and a parallel circuit connected between the first connection part and the second connection part, comprising a branch with a current intensity control device and a branch with an electrical resistor.

[0002] Internal combustion engines in motor vehicles do not produce any torque when stationary. For this reason, such internal combustion engines cannot be started automatically by injecting fuel. This requires that the internal combustion engine within the vehicle be subjected to torque in order to start. This torque is usually provided by a starter motor or an electric motor. Such an electric motor is necessary to start or start the internal combustion engine.

[0003] The starter of the combustion engine is powered by the vehicle's battery. At the moment of starting, i.e. when the starter motor starts running, its inductive load has a low resistance and a very high current flows from the battery through the starter. The starter's inductance practically represents a short circuit at the moment of starting. The resulting high current flow leads to drops in the battery voltage at the battery terminals. During a typical vehicle start-up process, the battery voltage drops below a limit after a short time. As a result, other consumers in the vehicle's electrical system, which require a minimum voltage, can no longer be supplied with sufficient electrical energy.

[0004] The voltage drop occurs in all vehicles with internal combustion engines during the starting process when the engine is started using a starter. Vehicles can be, for example, automobiles, rail vehicles, or aircraft. Ships are also considered vehicles within the meaning of this article.

[0005] In order to prevent this voltage drop during the starting process, especially in start-stop operation, which has become common today to save fuel, there are a variety of voltage support concepts, such as the use of support capacitors, the use of additional batteries and the use of starting current limiting systems.

[0006] A starting voltage or starting current limiting system is also known as a starting voltage drop limiter (SEB), start current limiter (SCL), voltage drop limiter (VDL), or similar. Such a starting current limiting system limits the starting voltage drop by reducing the current flowing from the battery to the starter. Voltage drops down to a defined lower limit are still acceptable. Furthermore, a starting time delay is accepted, since the starter does not receive the full available electrical energy from the battery during the starting process, but only a limited amount.

[0007] DE 10 2011 014 023 A1 describes a starting current limiting system with a first electrical connection that can be connected to a motor vehicle battery terminal, a second electrical connection that can be connected to a starter and a parallel circuit connected between the first connection and the second connection.

[0008] US 2008 / 0194152 A1 discloses a connector suitable for establishing an electrical connection with any number of batteries. The connector includes any number of features for assessing the operating characteristics associated with the battery, such as, but not limited to, voltage and temperature.

[0009] During the start-up process with a conventional battery, the battery voltage drops below 8 volts after just a few milliseconds. This initial voltage drop affects all electrical consumers connected to the battery. The initial voltage drop, which only occurs briefly, could be compensated for by upstream buffer capacitors, for example. During a conventional start-up process, the battery voltage briefly recovers to above 9 volts immediately after starting, before then dropping below 9 volts again. This second voltage drop cannot be absorbed by conventional buffer capacitors, as their capacity is only sufficient to compensate for the first voltage drop. The buffer capacitors are regularly discharged after the first voltage drop, and the second voltage drop during a start-up process leads to problems within the vehicle electrical system.In particular, engine control units, airbag control units and other control units can fail in the short term, as not every control unit is designed for such a low voltage level of less than 9 volts.

[0010] Starting current limiting systems are typically located between the battery and the starter motor. Conventional vehicle electrical system topologies include a battery, a starter motor, a generator, and a load network. Depending on the concept, the starter motor and the generator are each supplied with a separate line or with a combined starter-generator line. To prevent short circuits in the event of a crash, the starter line or the starter-generator line is irreversibly disconnected from the vehicle electrical system by a so-called safety battery terminal.

[0011] In order to limit the voltage drop in the battery, a starting current limiting system must be provided in addition to the fuse in the event of a crash.

[0012] In a conventional starting current limiting system, a parallel circuit is provided in the starter cable consisting of a branch with a resistor and a branch with a switch network, for example with semiconductor switches. When the combustion engine is started, the switch network is opened and current flows exclusively through the resistor. This limits the starting current and reduces the voltage drop at the battery terminal. Subsequently, after 100 ms, for example, the parallel branch with the switches is closed. The overall resistance of the parallel circuit decreases and an increased current flows from the battery to the starter. The current through the branch with the switches can be adjusted by a type of pulse operation of the switches, whereby a time-averaged resistance of this branch is established by pulsed switching of the switches on and off.

[0013] After the start-up process, the switch network can be opened again because the starter no longer requires additional power.

[0014] However, the multitude of functional components within the starting current limitation system poses a significant challenge in terms of available installation space. Especially in the area of ​​the vehicle battery, the available installation space is very limited, so additional functions always pose a design challenge.

[0015] The object of the invention was therefore to provide a starting current limitation system which can be integrated into existing installation spaces in a particularly simple manner.

[0016] This object is achieved by a starting current limiting system according to claim 1.

[0017] It is proposed that, in addition to the second branch with the electrical resistance, the first branch with the current control device and, if applicable, the first connection part are spatially arranged within a pole of the battery terminal.

[0018] A battery is usually provided with a standardized pole. In particular, the DIN standards DIN EN 50342-2 and DIN 72311 specify standard dimensions for the pole and a housing offset running between the poles. The pole is the area containing the battery terminal and is defined by the battery's side walls on the one hand and the battery's outer edges on the other. The pole preferably has a maximum dimension of 60 mm to 72.5 mm. The height of the pole is usually between 30 and 40 mm, preferably less than 35 mm. The current limiting system in question is arranged within this installation space, preferably using the longitudinal offset running between the poles.It is understood that the physical arrangement of the electrical resistance branch, the current control device branch, and the first connection part within the pole must be understood to mean that these assemblies are largely located therein. Should one of the assemblies be partially located outside the pole, but the starting current limiting system remains largely within the pole, this is encompassed by the meaning of the term "spatially within the pole."

[0019] The resistor used to reduce the starting current at the beginning of the cranking process is preferably low-ohm and can be formed from a single-piece resistor conductor. This resistor conductor can be made of a copper alloy, for example, manganin, an iron alloy, e.g., stainless steel and steel, an aluminum alloy, or another metallic alloy. The resistor is preferably formed from a strip or sheet and formed as a flat part. The flat part can be adapted to the installation space conditions by being preformed, in particular bent, before installation.

[0020] In particular, the resistor can be shaped such that at least one section runs parallel to a boundary wall and / or an outer edge of the pole. This allows the resistor to fit particularly closely to the pole or its boundary walls or outer edges. It is also proposed that parts of the resistor be guided along the boundary wall of the pole or the outer edge of the pole. This means that parts of the resistor are guided at a distance of between 1 and 10 mm from the boundary wall or the outer edge. This leads to optimal use of the installation space, since the battery pole terminal and / or the switch network and / or the first connection part and / or the like can be guided in the area encompassed by the resistor.

[0021] Preferably, the resistor is formed as a dimensionally stable angle, which gives the entire assembly dimensional stability.

[0022] A particularly narrow design is possible when the resistor is formed as a flat part and its width runs parallel to a longitudinal axis of the battery pole or battery terminal. The height of the pole is then optimally utilized with minimal space consumption within the pole by the resistor if its width essentially extends over the height of the pole.

[0023] The resistor is preferably connected to the first connection part. The connection can be made either directly by a short circuit or via a switch network, particularly one formed from semiconductor switches, as will be discussed below. The connection between the resistor and the connection part can be a material connection. A screw connection is also possible. Other connections, such as riveting, are also possible.

[0024] The first connection part is preferably a battery terminal. A battery terminal comprises at least two clamping jaws that encompass the terminal and can be frictionally connected to the terminal by means of a screw connection. Outlets can be provided on the clamping jaws, in particular a first outlet for the first connection part and a second outlet, for example for connecting the battery terminal to the vehicle's consumer network. As already explained at the beginning, this connection does not have to be protected in such a way that a voltage drop could occur at the battery terminals. The second outlet can be located in an area of ​​the terminal spanned by the resistor. The outlet can be arranged between the resistor and the terminal.

[0025] To optimise the installation space, it can be useful to attach the branch with the resistor and the branch with the current control device at different points, e.g. with different radial outlet directions or angles, on the battery pole, in particular at different points on the battery pole terminal. To make this possible, the first connection part can not only be monolithic, in one piece, but can also be formed from two spatially separated taps. A first tap can preferably be materially connected to the battery pole terminal. A second tap can also preferably be materially connected to the battery pole terminal. The two taps can be spatially separated from one another and are electrically connected to one another exclusively via the battery pole terminal. The branch with the current control device can be connected to the first tap.The branch with the electrical resistor can be connected to the second tap. The two taps are at the same electrical potential, as they are electrically shorted to each other via the battery terminal. However, the taps are spatially separated from each other, for example, arranged at different angles away from the battery terminal, thus optimizing installation space.

[0026] As mentioned, the first connection part can also be a single piece. In particular, the first connection part can be a power distribution bar. This can be formed, for example, as a flat part. In particular, the flat part of the power distribution bar and the flat part of the resistor can be arranged such that their widthwise extension directions run parallel to each other. In particular, this is essentially parallel to the longitudinal extension direction of the battery pole or the battery pole terminal.

[0027] Optimal use of installation space can be ensured in particular if the power distribution bar extends in at least two different planes. A first plane can run parallel to the longitudinal direction of the battery pole or the battery pole terminal. A second plane can run perpendicular to the longitudinal direction of the battery pole or the battery pole terminal. In the region of the second plane, a first connection region can be provided to connect the power distribution bar to the battery pole terminal. The second connection region of the power distribution bar can run at an angle to this, in particular at right angles to this, and runs parallel to the longitudinal direction of the battery pole. This second connection region can be used for connection to both the branch with the resistor and the branch with the current control device.For this purpose, for example, a connection for either the branch with the resistor or the branch with the current control device can be provided at two distal ends of the second connection region of the power distribution bar. These two distal ends can be arranged on different legs of the power distribution bar, in particular if the power distribution bar is an angle, in particular a dimensionally stable angle. The ends of the second connection region can be shaped such that they engage in a respective housing, in which a switch network is provided, on the one hand, to connect the power distribution bar to the resistor and on the other hand to form the current control device. The switches of the switch networks, which are in particular semiconductor switches, can be protected from environmental influences by the respective housings.

[0028] In particular, the second connection area of ​​the power distribution busbar can be formed as a flat part. As such, it can run parallel to a boundary wall or an outer edge of the pole in sections, or it can be routed along the boundary wall or the outer edge of the pole. This leads to optimal space utilization on the one hand, and the largest possible installation space encompassed by the second connection area on the other.

[0029] A connection for a generator or a consumer network within the motor vehicle can either be arranged on the first connection part of the power distribution rail or can be provided directly on the battery pole terminal as a further outlet next to the outlet to the first connection part.

[0030] The current intensity is adjusted when starting the combustion engine by switching a current control device on and off. In pulsed operation, switches can be switched on and off to adjust an average resistance of the current control device. Semiconductor switches are suitable for this purpose. Depending on the required current-carrying capacity, semiconductor switches can be arranged in parallel within the current control device. After starting, the starter motor no longer requires any additional current. To prevent corrosion on the starter cable and to be able to switch the starter cable to a potential-free state, it is proposed that at least a second switch network be provided in the branch with the electrical resistance.If, after the start-up process, when the combustion engine has already started, both the first and second switch networks are opened, the line between the starting current limiting system and the starter motor is completely disconnected from the battery. This disconnection is reversible and can be removed during the next start-up process. The switches within the branch with the electrical resistance can also be designed to ensure the necessary current-carrying capacity at the moment of starting.

[0031] As already explained, the maximum current-carrying capacity at the moment of starting must be ensured by the switch network in the electrical resistance branch. Therefore, the first switch network can be formed by at least two switches connected in parallel, so that the current-carrying capacity of each individual switch can be lower.

[0032] According to one exemplary embodiment, it is proposed that the branch with the current control device is arranged predominantly within a first circular segment around the battery terminal, and that the branch with the electrical resistance is arranged predominantly within a second circular segment around the battery terminal, different from the first circular segment. This leads to optimal use of installation space. It is understood that the circular segments can partially overlap, as long as a predominant area of ​​the circular segment does not overlap. In other words, the branch with the electrical resistance can partially extend into the first circular segment, and conversely, the branch with the current control device can partially extend into the second circular segment.

[0033] The subject matter is explained in more detail below using a drawing showing exemplary embodiments. The drawing shows: Fig. 1 shows a voltage curve on a conventional battery during a starting process without starting voltage drop limitation; Fig. 2 shows a schematic network topology between battery, starter, generator and consumer with starting voltage drop limitation, which is not part of the invention. Fig. 3 shows a schematic topology of a starting current limitation system with reversible shutdown; Fig. 4a shows a view of a battery terminal; Fig. 4b shows a plan view of a battery with battery terminals; Fig. 5 shows a schematic plan view of a spatial arrangement of a starting current limitation system; Fig. 6 shows a plan view of another spatial arrangement of a starting current limitation system; Fig. 7 shows a view of a possible arrangement of a starting current limitation system.

[0034] Fig. 1 shows the voltage 2 curve over a time 4 of approximately one second during a starting process. Two voltage curves 6a and 6b are shown, which are typical for a starting process. The voltage curves are preferably taken between the positive and negative battery terminals. It can be seen that the voltage curves 6a and 6b are similar to each other. The voltage curves 6a and 6b show the conventional, unregulated behavior of a voltage at battery terminals during the starting process.

[0035] It can be seen that at the moment of starting, at time Te, the voltage drops below 8 volts. The voltage then recovers, only to drop again below 9 volts at time T1. The voltage then continues to recover and reaches its initial value of approximately 12 volts after approximately 1 second.

[0036] The first voltage drop at time Te can be absorbed by buffer capacitors in the control units, ensuring that it never falls below 9 volts. However, the buffer capacitors are then discharged, and at the latest at time T1, when the voltage drops below 9 volts again, consumers in the vehicle's consumer network would be affected. This can lead to malfunctions and consumer failures. In addition to failures of navigation systems and entertainment systems within the vehicle, which are less safety-critical, it can also lead to failures of safety-relevant components, which must be avoided at all costs. This means that, in addition to increased comfort, safety aspects are also relevant for starting current limitation.

[0037] The electrical topology of a starting current limiting system is shown as an example in the Figuren 2 und 3 illustrated.

[0038] Fig. 2 shows a battery 8 with a first battery terminal 10 and a second battery terminal 12, with terminal 12 preferably being the positive terminal. A first line 14a branches off from battery terminal 12 to a consumer network 14. Consumer network 14 can be made up of comfort functions, such as air conditioning, navigation systems, entertainment systems, and the like, as well as safety-relevant systems, such as airbag control units, driver assistance systems, power steering, and the like. Consumer network 14 requires a constant voltage from battery 8 that is regularly above 9 volts. If the battery voltage drops below such a limit, malfunctions can occur within consumer network 14. Another line 16a branches off to a generator 16. Generator 16, also known as an alternator, represents an electrical energy source during operation for charging battery 8.

[0039] Furthermore, a cable 18a, which can also be designed as a terminal, is connected to pole 12 and leads to a starter 18. The starter 18 is an electric motor used to start the internal combustion engine. At the moment of starting, the internal combustion engine has no torque and can only be started by an external torque provided by the starter 18.

[0040] The starter 18 is a high-torque electric motor which, as an inductive load, has very low resistance when stationary. This means that a significant current flows from the battery 8 through the starter 18 at the moment of starting, which leads to the Fig. 1 shown voltage dips. To prevent such voltage dips, a starting current limiting system 20 is provided, which is formed from a branch 22a with a resistor 22 and a branch 24a with a current control device 24.

[0041] The operation of such a starting current limiting system 20 is well known. At the moment of starting, current flows exclusively through branch 22a. After a short time, for example, 100 ms, branch 24a is connected, forming a parallel circuit consisting of resistor 22 and current control device 24, through which the current flows. The current control device 24 can be operated in a pulsed manner, so that an average resistance is established across branch 24a. This allows the current to be adjusted via the starting current limiting system 20 such that the voltage at battery 8 across terminals 10 and 12 does not drop below 9 volts. Appropriate control electronics are provided.

[0042] Fig. 3 shows one to the in Fig. 2 In addition to the similar topology presented in Fig. 2 used assemblies, a further switch network 22b is provided in branch 22a with resistor 22. The current control device 24 and the switch network 22b can be formed by semiconductor switches, in particular semiconductor switches connected in parallel. The switches present in the switch network 22b are closed during starting. After the starting process is complete, the switches of the switch network 22b and the switches of the current control device 24 can be fully opened, so that the line 18a between the starting current limitation system 20 and the starter 18 is potential-free. This prevents corrosion on the line 18a and increases safety in the event of a crash.

[0043] The presented starting current limiting systems 20 must be installed within available space. According to the invention, it has been recognized that this is possible in the pole, preferably of the positive battery terminal 12. Fig. 4a shows a battery 8 with one pole 12 and one pole 10. The two poles 10, 12 are each surrounded by a pole 26a, 26b. The pole 26a is delimited by the two boundary walls 8a and 8b of the battery 8 as well as the outer edges 8c, 8d of the battery 8.

[0044] The spatial alignment of the boundary walls 8a, 8b and the outer edges 8c, 8d is shown below in the Fig. 4a The boundary wall 8a preferably runs parallel to the xz plane. The boundary wall 8b preferably runs parallel to the yz plane. The outer edge 8c runs parallel to the x-axis, and the outer wall 8d runs parallel to the y-axis. The longitudinal propagation direction 12a of the battery pole 12 or the battery pole terminal runs parallel to the z-axis.

[0045] Between the pole 26a and the pole 26b there is an offset 26c, the volume of which can be used in the design of the starting current limiting system 20.

[0046] The structure of the battery 4a essentially corresponds to DIN EN 50342-2.

[0047] The battery according to the Fig. 4a is in the Fig. 4b shown in a top view. The surfaces of the poles 26a, 26b are visible. The subject starting current limiting system 20 is preferably arranged within the surface of the pole 26a and can extend into the surface of the offset 26c.

[0048] Fig. 5 shows the arrangement of a starting current limiting system 20 in the pole 26a. It can be seen that a battery pole terminal 28 is connected to the battery pole 12. A connection part formed as a power distribution bar 30 is connected in a materially bonded manner to the battery pole terminal 28. In the region of the connection between the battery pole terminal 28 and the power distribution bar 30, the power distribution bar 30 can be formed as a flat part and extend, for example, parallel to the xy plane. This would be a first electrical tap of the first connection part. The first connection part can extend from this first electrical tap into a second electrical tap, which is arranged at an angle to the first electrical tap.

[0049] The power distribution rail 30 can preferably be formed as a curved flat part, wherein the second electrical tap, which is formed for connection to respective switches 32a, 32b, can extend perpendicular to the xy plane. The second electrical tap preferably extends partially parallel to the xz plane and partially parallel to the yz plane. In particular, the region of the second electrical tap that is directed in the direction of the switches 32a extends parallel to the yz plane. The region that runs in the direction of the switches 32b is preferably arranged parallel to the xz plane. The width direction of the power distribution rail in the region of the second tap preferably runs parallel to the z direction. An arrangement in a respective plane preferably means that the width direction of the respective flat part runs parallel to such a plane.

[0050] The switches 32a are semiconductor switches and correspond to the switches of the switching network 22b. The switches 32a connect the power distribution bar 30 to the resistor 22. The resistor is preferably shaped as a dimensionally stable, curved angle. In particular, the resistor 22 is formed as a flat part, with its width extending in the direction of the z-axis. A first leg of the resistor 22 can run parallel to the xz plane. A second, angled leg can preferably run parallel to the yz plane. Starting from the first leg, the resistor 22 extends from the switches 32a to the second connection part 34.

[0051] The power distribution busbar 30 is connected at its first tap to switches 32b, which are designed to control the current intensity during starting and are controlled accordingly. Via these switches 32b, the power distribution busbar 30 is connected to the second connection part 34. Starting from the second connection part 34, the line 18a extends to the starter 18. The electrical connection between the line 18a and the second connection part 34 can extend into the offset 26c.

[0052] Fig. 6 shows a further embodiment of an arrangement of a starting current limiting system in a pole 26a. It can be seen that, starting from the battery pole terminal 28, the power distribution bar 30 has a first electrical tap 30a connected to the battery pole terminal and a second electrical tap 30b connected to the battery pole terminal 28. The electrical taps 30a, 30b are both electrically connected to the battery pole terminal 28, but are spatially separated from each other. In contrast, the power distribution bar 30 according to the Fig. 5 in one piece and connected at their distal ends to a switch network 32a, 32b.

[0053] A plurality of switches of the switch network 32b can extend from the first tap 30a, which can be formed as a flat part and, for example, be U-shaped. These switches of the switch network 32b can be connected to one end of a second connection part 34, which engages the U of the first tap 30a. The first tap 30a, the second tap 30a, and / or the battery terminal 28 can have connections for the generator line 16a and the line 14a to the consumption network 14.

[0054] The second electrical tap 30b can be connected to the resistor 22 via a switch network 32a. In this case, the resistor runs as a flat part parallel to the yz plane.

[0055] As in the Figuren 5 und 6 As can be seen, the connection between the respective switching network 32a, 32b and the resistor 22 can be made of two parts. In particular, the resistor can be formed from a different alloy than the flat parts of the switching networks 32a, 32b. The flat parts that connect the switching networks 32a, 32b to the resistor are preferably made of copper or alloys thereof. The resistor 22 is preferably made of a resistance alloy, such as a copper-manganese alloy with further components of nickel, aluminum, tin, and / or iron.

[0056] Fig. 7shows a further schematic view of a structure of a starting current limitation system 20. It can be seen that, starting from the battery terminal 28, an electrical tap 29 extends parallel to the xy plane and is connected to the power distribution bar 30. Starting from this electrical tap 29, the power distribution bar 30 is bent such that a first end 30', in the installed state, runs parallel to the boundary wall 8b and along the boundary wall 8b. A second end 30" runs parallel to the boundary wall 8a and along it.

[0057] The first end 30' terminates in a housing 36b, in which the switch network 32b is housed. Extending from this switch network 32b, an electrical tap 33 formed as a flat part extends from the housing 36b and is connected to the resistor 22 outside the housing 36b. The tap 33 is connected to the connection part 34.

[0058] The second end 30" of the power distribution bar 30 extends into a housing 36a in which the switch network 32a is arranged.

[0059] The width direction of the resistor is parallel to the z-axis. A first leg 22' of the resistor 22 runs parallel to the x-axis when installed. A second leg 22" of the resistor runs parallel to the y-axis when installed.

[0060] The leg 22" is connected to an output of the switching circuit 32a. The leg 22' is connected to an output of the switching circuit 32b.

[0061] The resistor 22 is a bent angle that extends from the leg 22' into the leg 22" running at a right angle thereto. The leg 22' runs parallel and along the outer edge 8c. The leg 22" runs parallel and along the outer edge 8d. The resistor 22 opens into the second connection part 34.

[0062] An electrical tap 38 of the battery pole terminal 28 is provided in the area spanned between the legs 22' and 22". Via this electrical tap 38, which is preferably spatially arranged between the battery pole terminal 28 and the resistor 22, a consumption network and / or a generator can be electrically connected to the battery pole 12.

[0063] The branch with the resistor 22 runs in the region of the outer edges 8c and 8d, whereas the current distribution bar 30 and the branch with the current control device formed by the switching circuit 32b are arranged in the region of the boundary wall 8b and the outer edge 8c. Thus, the areas used by the respective branches only partially overlap, and the respective branches are predominantly arranged in mutually different circular segments around the battery terminal 12.

[0064] Preferably, the power distribution bar 30 surrounds the battery pole 12 in a first circular segment and the resistor 22 surrounds the battery pole 12 in a second circular segment.

[0065] By arranging the starting current limiting system 20 in the Polish 26a, installation space is optimized while ensuring electrical safety.
