Definitions

  • the present invention relates to a battery according to the preamble of claim 1 and a battery control method according to the preamble of claim 9.
  • Batteries, in particular batteries that have a large number of cell modules, are monitored with regard to electrical and physical states. This also includes the monitoring of thermal states, in particular the detection of so-called thermal breakdowns.
  • the detection of a thermal event (thermal runaway) in one or more cells of a battery or a battery system the pressure or the pressure curve is evaluated, the pressure rise as a result of the opening of a pressure relief valve, as a result of which the interior of a battery rises sharply in a short time.
  • This pressure measurement is carried out, for example, by means of a pressure sensor, which can be arranged on the main circuit board, for example, as part of the battery management system (BMS).
  • BMS battery management system
  • Such a "thermal event" (thermal runaway) is a condition in which chemical processes cause the heating to increase automatically without any external influence, such as the current load, and the chemical process is accelerated at the same time.
  • Accommodating the pressure sensor on the main circuit board is disadvantageous because this requires a further structural increase, making it difficult to accommodate it in the battery and further complicating the verification of the data from the pressure sensor on the main circuit board in accordance with the ASIL standard.
  • HV battery high-voltage battery
  • main control unit with a main circuit board, a main processor and a plurality of micro/electronic elements or components,
  • a switch box in which at least two contactors are arranged, at least one each for an HV + line and an HV line for connection to a main circuit.
  • the core of the invention is that to detect a thermal event, i.e. exceeding a target temperature, a pressure sensor is provided for measuring the pressure inside the battery, and the pressure sensor is arranged outside the main circuit board at one of the following locations:
  • a cell measurement circuit board means a circuit board that is arranged directly on or in a cell module and includes microelectronic parts and components that are essentially used to control and evaluate the respective cell module and are connected to the main control unit and are controlled by it.
  • the secondary circuit board is another central circuit board that is different from the main control unit and/or the main circuit board and that is also connected to the main control unit.
  • switch box instead of the term “switch box” used here, "S-Box”, “Switch-Box” or “BJB” (battery junction box) is also often used.
  • E-Box for the same component is also found somewhat less frequently.
  • connection is not to be understood as limiting and means both one or more connections to the voltage and power supply as well as to data-carrying communication.
  • the communication can in particular be one of the usual bus technologies or serial interfaces, such as isoSPi, be formed by separate individual cables or modulated onto one or more current-carrying individual cables.
  • a pressure sensor is arranged on a plurality of cell measurement boards, in particular if a pressure sensor is provided on each cell measurement board.
  • the great advantage of this solution is that a thermal event is immediately detected in a specific cell module or a group of cell modules in their vicinity.
  • the source of the event can be delimited from the sequence of the detecting pressure sensors.
  • a temperature sensor is also provided on at least one of the cell measurement boards, which is arranged adjacent to the at least one pressure sensor on the same cell measurement board and/or on a cell measurement board of an adjacent cell module.
  • the at least one pressure sensor is arranged on a central secondary circuit board, with the secondary circuit board being fixed in the switch box, with an improvement to this being that at least one, in particular all, microelectronic high-voltage elements (HV elements) are arranged in the switch box, by arranging them either on the secondary circuit board or on a separate high-voltage circuit board.
  • HV elements microelectronic high-voltage elements
  • the great advantage of taking over the microelectronic HV elements on a central secondary circuit board is that the status is recorded and evaluated in the vicinity of the high-voltage lines (HV+, HV-) and the cell modules, and the shielding and protection of the data from these HV- elements compared to the rest of the microelectronic elements and components on the motherboard, and compliance with ASIL standards is greatly facilitated. Since in the present case communication with the ASIL standard is required for the central secondary circuit board and this is used for the pressure signal, no additional communication interface is advantageously required.
  • HV elements here means in particular analog-digital converters (ADC) as galvanically isolated capacitive couplers, inductive couplers or opto-couplers for data transmission from the high-voltage range to a low-voltage range, as well as voltage measuring elements/chips.
  • ADC analog-digital converters
  • An m-secondary processor is advantageously arranged on the secondary circuit board and/or the high-voltage circuit board, which is primarily used for processing the data and processing of the m-components arranged on the respective circuit board and is connected to the main control unit and in particular its main microprocessor.
  • the battery has an outer battery housing, which is usually closed in a dust-tight and/or vapour-tight manner, and the battery elements are arranged overall within this battery housing.
  • a battery housing should also be understood as a multi-part housing if the individual housing parts are connected to one another via a connecting channel or connecting space, but continue to form a common battery space on the outside. This could be the case here if the switch box is flanged or screwed onto or on a battery housing and an opening or channel is formed between the switch box and the interior of the battery housing, which is sealed against the atmosphere. As a rule, connecting lines are laid in this channel or this opening.
  • the switch box In order to shield the interior of the battery, shield against electromagnetic interference and protect against contamination, it is advantageous if the switch box has its own at least partially closed, in particular completely closed, box housing. In the event that electronics are installed in the box, it is advantageous if this box has a metal housing or is formed from it. The great advantage here is the easy handling and the possibility of prefabrication.
  • a switch box which consists of many components, can be manufactured externally as a unit and connected to the HV battery to form a unit in just a few steps.
  • the invention also includes a method for operating a battery, in particular an HV battery, which includes a battery management system (BMS) with a main controller and a main circuit board and has a plurality of cell modules.
  • BMS battery management system
  • the essence of the inventive method is that at least one pressure sensor is provided in the interior of the battery and/or in the area of a cell compartment or the cell modules to detect when a thermal limit value, generally referred to as a thermal event, is exceeded and is arranged outside the main circuit board .
  • a thermal limit value generally referred to as a thermal event
  • high-voltage primarily means a voltage range of 60V to 2,000V DC, in particular 60V to 1,500V DC, which particularly affects the power requirements of e-vehicles, such as electrically powered cars, trucks and buses.
  • FIG. 1 shows a schematic plan view of an HV battery with a two-story cell compartment
  • Fig. 2 shows a schematic, alternative embodiment of a HV battery with a one-story cell compartment and a secondary circuit board in the switch box and
  • FIG. 3 shows a further embodiment of an HV battery, similar to FIG. 2, the secondary circuit board comprising the HV elements.
  • HV battery 1 shows a schematic structure of an HV battery 1, which has a battery housing 15 as essential components, within which a main control unit 10, a switch box 20 and a cell compartment 30, which has two levels 35, 36.
  • the cell compartment 30 is divided into a plurality of cell modules 31.1...31.n, which is indicated by a dashed transverse line was implied. Each cell module 31.1...31.n has an associated cell measurement board 32.1...32.n.
  • the main control unit 10 and its main circuit board 11 are connected via the LV line 43 to a central control and supply unit 2 in a data-carrying and power-carrying manner.
  • the battery 1 is connected to one or more loads 3 via the HV lines 40, 41, as indicated very schematically.
  • the HV+ line 40 is routed into the switch box 20 and to the contactor 8 there, via which the line 40 is switched.
  • the HV - line 41 is also in the switch box 20 and the contactor 9 out.
  • an auxiliary current path 42 is provided in the switch box 20 on the HV+ line for the operation of the contactor 12, which acts as a pre-charging contactor.
  • a current sensor 24 is provided in the switch box 20, other fuses, resistors or other components are not shown.
  • the main circuit board 11 is connected via the line connection 44 to the switch box 20 or individual components and components in the switch box 20, which was not differentiated in detail here.
  • the main circuit board 11 comprises a plurality of micro/electronic elements 5.1, 5.2, 5.3 and a main microprocessor 4.
  • the pressure sensor 6 according to the invention is arranged in the switch box 20 and is connected to the main control unit 10 or its main circuit board 11 via a separate line connection 45 tied together.
  • a temperature sensor 7 is fitted on the cell measuring circuit board 32.2 and thus in the direct vicinity of the pressure sensor 6 .
  • the temperature sensor 7 is applied directly to the cell measuring circuit board 32.2 as a surface mounted device (SMD component).
  • SMD component surface mounted device
  • the battery 1 has only one level of a cell compartment 30 . It is central that a secondary circuit board 21 is arranged in the switch box 20, on which the pressure sensor 6 is placed as an SMD component. This secondary circuit board 21 also includes an m-secondary processor 23 and for detecting and processing the HV states required microelectronic HV elements 5.1.

  • ADC analog-to-digital converters
  • the current sensor 24 of the HV line is connected to the secondary circuit board 21 and/or the m-secondary processor 23 via a separate line 47 .
  • This secondary circuit board 21 itself, as a subordinate element in the BMS, is connected on the one hand via the line 44 to the main circuit board 11 and the components of the cell compartment 30 via the line 46 .
  • This means that all components that monitor and process the HV functions are combined in a separate room, namely the switch box 20, and can be suitably shielded and protected.
