Definitions
- the invention relates to a method for monitoring and / or charging control of a battery composed of modules, in particular in a battery-operated vehicle according to the preamble of claim 1 and a device according to the preamble of claim 7 for carrying out this method.
- Electric vehicles are already used for a number of purposes, and draw their energy from rechargeable batteries, in particular from lead accumulators connected in series. Such environmentally friendly drives are also beginning to gain acceptance in road vehicles.
- a major problem is to monitor the operational readiness of the battery modules and to indicate their ready status.
- Measurement data for determining the state of charge are recorded in the remote control transmitter and transmitted to the device to be controlled using a transmission medium such as infrared light, ultrasound or electromagnetic waves.
- An evaluation circuit and a display element for displaying the state of charge are contained in the device to be controlled.
- Such Wireless transmission of measurement data recorded on the battery to an evaluation unit is only possible under favorable circumstances and is not suitable in particular for a motor vehicle.
- the object of the invention is to develop a method of the type mentioned at the outset such that the operating state of a battery can be monitored with little effort and with good functionality.
- the evaluation unit is connected to the power cable.
- the measurement data recorded directly on the battery, in particular the terminal voltage and the temperature, are transmitted to the evaluation unit by means of a coded AC voltage via the power cable.
- the signal lines previously used can be completely eliminated. Electrical isolation is no longer necessary.
- the circuit outlay for the coded transmission of the measurement data is considerably less in comparison to additional signal lines, in particular if batteries are used which are made up of a plurality of modules and / or cells and the individual modules and / or cells for a statement about the functional state of the entire association should be monitored.
- the measured values can each be transmitted directly coded to the evaluation unit or passed on to other modules and / or cells and transmitted from there to the evaluation unit.
- the transmission is advantageously serial and frequency modulated.
- the simultaneous acquisition of measurement data on the individual modules is essential for the assessment of the functional status of a battery from individual modules of an overall association.
- the acquisition of the measurement data is advantageously triggered by the central evaluation unit, so that these are acquired simultaneously on all modules.
- These measurement data are digitized and then temporarily stored in memory circuits on the modules and from there serially queried and evaluated by the evaluation unit, each module being assigned a controllable module address.
- an oscillating circuit is used in a manner known per se to generate an alternating voltage, a modulation voltage dropping due to the excitation of the oscillating circuit on the battery and / or the modules and / or the cells.
- a microcomputer is used to evaluate the measurement data.
- the evaluation circuit can be integrated in a microcomputer that is also used for other functions.
- Memory circuits for temporarily storing measurement data are advantageously integrated in each module, so that no complex wiring is required between the sensors and these intermediate memories.
- Fig. 1 is a block diagram of an apparatus for performing the method for a
- Fig. 2 is a circuit diagram for a series resonant circuit for the transmission of measurement data with a coded AC voltage.
- a battery 1 is shown, from the power cables 2 and 3 lead to consumers, which are shown schematically as a load resistor 4.
- a power shunt 5 and a main switch 6 are included in the power cable 2.
- the measuring shunt 5 is connected to a central evaluation unit 9 via measuring lines 7 and 8. This also has a connection to the power cables 2, 3 via signal lines 10, 11.
- the battery 1 is intended to represent the energy source in a battery-operated vehicle, the load resistor 4 essentially representing an electric drive motor.
- the battery 1 is constructed in a modular manner, with conventional lead-acid batteries being used as modules 12 to 17 connected in series.
- a module circuit as a module controller 19 to 24 is integrated in each module 12 to 17.
- each module controller 19 to 24 is connected to the terminals 25, 26 of each assigned module 12 to 17 for detecting the terminal voltage. Furthermore, each module controller 19 to 24 is connected to further measuring sensors (not shown) assigned to each module, for example to temperature sensors.
- the central evaluation unit 9 contains, in particular, high-voltage filters, rectifiers, amplifiers and a microcomputer.
- the module controllers 19 to 24 further contain digitizing and buffering devices that interact with the central evaluation unit 9 and a connection to a series resonant circuit via whose alternating voltage buffered measurement data can be transmitted.
- the area 27 framed by dashed lines is on the battery side, reference number 28 denoting a module of the battery and R1 indicating an ohmic resistance and L2 indicating an inductance of a complex internal resistance of the battery.
- Inductors L2 and L3 represent the leads with line inductances.
- the remaining area of the circuit is assigned to the module controller.
- the feed lines with the inductors L2 and L3 are connected to a transistor Q2 which, in conjunction with further resistors, in particular R2, R3, R4, R5 and a capacitor C1, forms a series resonant circuit which is operated close to the resonance frequency.
- An alternating voltage which is generated via an oscillator 1, is fed in via a further capacitance C2 at the branching point of the resistors R3, R4, R5.
- the Positive pole 29 in the battery-side part is connected to resistor R4 via an inductor L4 and further to ground 30 via a smoothing capacitor C3
- the circuit part of the central evaluation unit 9 (FIG. 1) for sending coded information is constructed similarly. There are differences in the tuning of the resonant circuit L1, R1, L2, L3 and C1, since the entire battery 1 (FIG. 1) is effective as the source voltage 28
- FIGS. 1 and 2 have the following function
- the module voltage and the module temperature are recorded on the individual modules 12 to 17. If a module consists of several cells, these are also monitored with regard to their voltage level
- the temporarily stored measurement data are queried sequentially by the central evaluation unit 9.
- an address code is transmitted via the power cable.
- the addressed module controller replies in the echo process, with the help of a start bit (low potential), 8 data bits and a stop bit (high potential) successively transmitting the temporarily stored voltage value and temperature value from a module controller to the central evaluation unit Then a next module controller is queried.
- the evaluation is carried out there according to criteria known per se and the charge status of the battery is displayed
