Description

Technical Field

[0001] The present invention relates to a cover of a cell contact system for an electrical energy storage device for a vehicle. The present invention also relates to an electrical energy storage device and a vehicle including the cover or the electrical energy storage device. Background Art

[0002] Vehicles batteries known in reality (for example, vehicle batteries used as energy storage devices or traction batteries in hybrid or electric vehicles) typically have a plurality of battery storage cells arranged in stacks, which form one or more battery cell stacks (Batteriezellenstapel). The cell electrodes of these battery cell stacks are usually electrically connected or interconnected using a cell contact system (Zellkontaktiersystem). A cell control device or a cell module controller (also referred to as a cell management controller) is also used to control the energy flow. Especially in a battery system consisting of a plurality of battery cell stacks arranged one above the other and / or side by side (i.e., a so-called multi-layer high-voltage battery or multi-layer battery), the cell control device is usually located laterally beside the battery cell stacks. Thus, the cell control device disadvantageously occupies the position required for an additional battery cell stack in the battery system. Therefore, the solutions adopted by known systems arrange the cell control device outside the grouped battery cell stacks or completely outside the electrical energy storage device. The main disadvantage of this is that the wiring work is increased, and the cell control device is more vulnerable to damage from external influences. Especially for multi-layer high-voltage batteries or multi-layer batteries, it is desirable to more effectively utilize the required installation space without these disadvantages.

[0003] In this context, document D1 (US 10,714,717 B2) proposes a solution that integrates the cell module controller into the cell contact system. The disadvantage of this is that when the cover is removed, for example, when replacing a defective cell module controller, the live parts of the cell contact system are exposed and may thus pose a danger to bystanders. In addition, the position of the cell module controller is disadvantageously restricted to the arrangement between the cell electrodes. This position is disadvantageously located above the exhaust port of the battery storage cell, such that in the case of exhaust of the battery storage cell, the risk of damage to the cell module controller system is increased due to the escaping hot air. Summary of the Invention

[0004] The object of the present invention is to provide a technology that can avoid the disadvantages of known methods. In particular, the object of the present invention is to improve the installation space required for known energy storage devices without compromising the safety of bystanders from electric shock and / or without increasing the risk of damage to the cell control device during exhaust.

[0005] These objects are achieved by a device having the features of the independent claims. Advantageous refinements are specified in the dependent claims and in the description.

[0006] The basic idea of the invention is to integrate a control device (e.g., at least one cell control device) into the insulating body of the high-voltage cover. In this regard, the control device and the insulating body form a combined component.

[0007] On the one hand, it relates to a cover for a cell contact system of a vehicle electrical energy storage device.

[0008] The cover includes an insulating body (e.g., plate-shaped) and at least one control device. To provide an anti-touch protector (e.g., to prevent electric shock), the insulating body is designed to cover the cell contact system.

[0009] The at least one control device can preferably be designed as a cell control device, which is configured to control the electrical energy flow through the cell contact system. The at least one control device is at least partially accommodated by the insulating body.

[0010] The advantages of the invention are that in the event of a malfunction of the control device, the cover can be removed and replaced as a whole (i.e., the insulating body together with the at least one control device). Thereby, the risk of bystander electric shock can be reduced during the disassembly process. At the same time, the integration of the at least one control device in the insulating body can represent an advantageous arrangement option, because in this way the installation space released on the side of the battery cell stack can be utilized, for example, for other battery cell stacks or other purposes. At the same time, the at least one control device is no longer limited to being located above the exhaust port, but can be arranged at any suitable position on the insulating body, thereby reducing the risk of damaging the at least one control device during exhaust. By integrating the at least one control device into the insulating body, the installation space required in the height direction (Z direction) can also be reduced. Advantageously, the functions of the two components are combined into one component in order to minimize the required installation space.

[0011] The at least one control device can be, for example, a Cell Management Controller (CMC). The at least one control device can be designed to detect the duration of the electrical energy flow and / or the temperature of the cell contact system (e.g., in the contact area in contact with the cell electrodes of the battery cell stack). The insulating body can be, for example, an insulating plate and / or an insulating cover. The connection between the storage cell and the control device can be fixed or detachable.

[0012] In one embodiment, the insulating body may include at least one recess (e.g., at least one indentation). The at least one control device can be fixed in the at least one recess. For example, the at least one recess defines an internal volume, and the at least one control device (e.g., completely) is arranged in the internal volume. For example, the insulating body can be a housing base (Gehäuseunterschale) of the control device. Thereby, the installation space required in the height direction can be further reduced.

[0013] In one embodiment, the at least one control device can be (e.g., completely) embedded and / or buried in the at least one recess. Optionally, the end side (e.g., the upper side) of the at least one control device opposite to the insulating body can be substantially flush with the end side (e.g., the upper side) of the insulating body and / or terminate at the end side of the insulating body. For example, the end side of the at least one control device opposite to the insulating body and the end side of the insulating body are in one plane. It is also conceivable that the at least one control device does not protrude outside the insulating body. Thereby, the at least one control device can be protected from external damage and / or the installation space required in the height direction can be further reduced.

[0014] In one embodiment, the at least one control device can be non-removably connected to the insulating body. Preferably, the at least one control device is non-removably connected to the insulating body by at least one fixing rivet. Optionally, the insulating body can be designed as a plastic injection molded part (Kunststoff-Spritzgussteil). For example, it is conceivable that the at least one control device is at least partially integrated into the insulating body by overmolding. However, any other suitable fixing means can also be conceivable, such as a form-fitting means (e.g., in the form of locking elements) and / or an interference fit means (e.g., by pressing the at least one control device into the insulating body) and / or a material bonding means (e.g., by means of an adhesive). The advantage of this is that the cover can be assembled and disassembled as an integral unit.

[0015] In one embodiment, the insulating body may include a material that is a non-electric conductor. For example, non-conductors include plastics (e.g., glass fiber reinforced plastics), ceramic materials, glass materials, and / or silicone resin materials.

[0016] Alternatively or additionally, it is conceivable that the at least one control device has an electrical insulation protection cap, which is arranged on the end side (e.g., the upper side) of the at least one control device opposite to and / or facing away from the insulating body. Preferably, the end side is substantially flush with the end side (e.g., the upper side) of the insulating body. Thereby, the risk of electric shock to bystanders can be further reduced.

[0017] In one embodiment, the cover may further include at least one conductor device configured to electrically connect the at least one control device to the cell contact system. Preferably, the at least one conductor device includes a flexible conductor foil. Thereby, the weight of the cover can be advantageously reduced.

[0018] It is conceivable that the insulating body includes at least one through-hole, and the at least one conductor device extends from the side (e.g., the upper side) of the insulating body where the at least one control device is arranged, through the at least one through-hole to the side (e.g., the lower side) of the insulating body opposite to the control device.

[0019] In one embodiment, the at least one control device may include a plurality of control devices. The insulating body may include a plurality of recesses (e.g., a plurality of depressions). One of the plurality of control devices may be fixed in a corresponding one of the plurality of recesses. Thereby, the wiring workload can be further reduced. Advantageously, for example, the control devices for a plurality of battery cell stacks can also be accommodated in the insulating body.

[0020] Other aspects relate to an electrical energy storage device. The electrical energy storage device includes a battery cell stack, a cell contact system, and a cover as disclosed herein. The battery cell stack includes a plurality of cell electrodes. The cell contact system electrically connects and / or interconnects the cell electrodes (e.g., in series with each other). The insulating body covers the cell contact system to form an anti-touch protector (e.g., completely and / or substantially flush). Optionally, the electrical energy storage cell includes a housing. The battery cell stack, the cell contact system, and the cover are arranged in the housing. The housing may further include, for example, a housing cover that covers the cover. The battery cell stack may include a plurality of storage cells arranged successively in a stacking direction. However, it is also conceivable that the battery cell stack includes multiple rows of storage cells arranged successively in a direction transverse to the stacking direction.

[0021] In one embodiment, the cell contact system may be arranged between the cover and the battery cell stack. This means that the energized cell contact system will not leak out, thereby further improving electrical safety.

[0022] Alternatively or additionally, the at least one recess may be arranged on the side of the insulating body opposite to and / or facing away from the cell contact system (e.g., the upper side).

[0023] In one embodiment, the insulating body and / or the battery cell stack may include at least one exhaust port for discharging the gas escaping from the battery cell stack. For example, the at least one control device may be arranged not to overlap with the at least one exhaust port. Alternatively or additionally, the at least one control device may be arranged not to be aligned with the at least one exhaust port. Alternatively or additionally, the at least one control device may be arranged to be laterally offset (e.g., along a direction transverse to the stacking direction of the battery cell stack) with respect to the at least one exhaust port. Thereby, the escaping gas can be guided past the at least one control device in the case of battery exhaust. Thereby, damage to the at least one control device caused by the escaping gas during exhaust can be prevented.

[0024] In one embodiment, the at least one control device may include a plurality of control devices. Alternatively or additionally, the at least one conductor device may include a plurality of conductor devices. When viewed in the stacking direction of the battery cell stack or in a direction transverse to the stacking direction of the battery cell stack, the plurality of control devices and / or the plurality of conductor devices may be arranged to be offset from each other. Thereby, the wiring work can be further reduced.

[0025] In one embodiment, the cell contact system may include a carrier plate and at least one cell electrode connector received by the carrier plate. Preferably, the at least one cell electrode connector electrically connects a part of the plurality of cell electrodes (e.g., two cell electrodes among the plurality of cell electrodes) to each other. The at least one conductor device may electrically connect the at least one cell electrode connector to the at least one control device.

[0026] In one embodiment, the electrical energy storage device may include other battery cell stacks as disclosed herein, other cell contact systems as disclosed herein, and other covers as disclosed herein. The other battery cell stacks may include a plurality of cell electrodes. The other cell contact systems may electrically connect the cell electrodes of the other battery cell stacks (e.g., connect them in series and / or connect them). The insulating body of the other cover may cover the other cell contact system to form a touch protection device. The other battery cell stacks may be arranged laterally beside the battery cell stack or in a stacked manner above the cover. Thereby, the installation space released by integrating the at least one control device into the insulating body can be advantageously used for the other battery cell stacks, so that the battery capacity can be increased.

[0027] Other aspects relate to a vehicle (e.g., a motor vehicle) that includes a cover as disclosed herein or an electrical energy storage device as disclosed herein. Preferably, the motor vehicle is a commercial vehicle. In other words, a commercial vehicle can be a motor vehicle designed for transporting people, transporting goods, or towing a trailer by its construction and equipment. For example, the motor vehicle can be a truck, a bus, and / or a semi-trailer that is at least partially electrically driven.

[0028] The foregoing preferred embodiments and features of the present invention can be combined with each other as needed. BRIEF DESCRIPTION OF THE DRAWINGS
