Description

The entire content of the DE 10-2011-015746 priority application is herewith incorporated by reference into the present application.

The invention relates to a method for the handling and servicing of an electrochemical cell, a method for the handling and servicing of a battery comprising said electrochemical cells, an electrochemical cell designed to realize the method as well as a corresponding battery comprising said electrochemical cells.

Electrochemical energy storages, also referred to as electrochemical or galvanic cells in the following, are frequently produced in the form of stackable units, wherein by combining a plurality of such cells, so-called batteries can be produced for various applications, particularly for use in electrically operated motor vehicles. The invention will be described with reference to its use in a motor vehicle, whereby it is however pointed out that such a method and accordingly designed electrochemical cell, or such a battery respectively, can also be operated independently of motor vehicles, e.g. in stationary use.

Methods for handling and servicing electrochemical cells and/or batteries as well as accordingly designed electrochemical cells and/or batteries are known from the prior art, albeit associated with complicated handling and servicing.

The object of the present invention is that of an improved technical teaching for the handling and servicing of electrochemical cells and/or batteries.

This object is accomplished by a method in accordance with claim 1 for the handling and servicing of an electrochemical cell, or battery respectively, comprising a plurality of such electrochemical cells, and by an electrochemical cell in accordance with claim 11, as well as by a battery in accordance with claim 16 comprising a plurality of such electrochemical cells. The subclaims relate to advantageous further developments of the invention.

In accordance with a first aspect, a method for the handling and servicing of an electrochemical cell, preferably a battery having a plurality of such electrochemical cells, comprising a controller, particularly a cell controller, preferably a battery controller, at least one sensor connected to the controller for acquiring parameter data on the electrochemical cell or battery, a storage apparatus preferably having non-volatile memory, particularly a flash memory, and a data transmission unit, is accomplished by the method comprising the following steps: acquiring parameter data on the electrochemical cell or battery respectively, feeding the acquired parameter data to the cell controller, the controller calculating control data as a function of the supplied parameter data, feeding the control data to the storage apparatus, reading out the control data from the storage apparatus to the data transmission unit, and the data transmission unit transmitting the read-out control data to a display apparatus, the data transmission unit particularly wirelessly transmitting the read-out control data to a display apparatus.

One advantage of this design is that a user is able to readily determine the status of the electrochemical cell or battery respectively from the control data, e.g. for handling or servicing purposes, so as to initiate measures for maintaining or increasing the efficiency or safety as needed. It is also possible to selectively replace electrochemical cells or batteries during maintenance work in a shop in order to for example increase the overall performance when upgrading. This is advantageous particularly for determining the status of a slightly damaged electrochemical cell or an electrochemical cell no longer covered by maintenance service, respectively a corresponding arrangement of electrochemical cells and/or a battery, as the cells or the cell arrangement or the battery should not be transported. Moreover, obtaining control data and/or parameter data information in particular is advantageous from a safety standpoint with respect to a technician or to service, particularly in the case of large battery assemblies. This is of particular advantage when the battery fails, protective components have been actuated or a battery management system BMS and/or battery management monitoring system BMMS or a protective circuit malfunctions or ceases operation.

Control data is to be understood in the present context not only as a plurality of control data, but, where applicable, also one single control datum. Accordingly, predetermined control values in the present context is not only to be understood as a plurality of predetermined control values, but also, where applicable, one single predetermined control value.

An electrochemical cell in the present context is to be understood as an electrochemical energy storage; i.e. a device which stores energy in chemical form, dispenses the energy to a load in electrical form, and can preferably also absorb it in electrical form from a charging device. Galvanic cells and fuel cells are important examples of such electrochemical energy storages. The electrochemical cell comprises at least one first and one second device for storing electrically different charges as well as means for producing an operative electrical connection between said two devices, whereby charge carriers can be positioned between the two devices. A means for producing an operative electrical connection refers for example to an electrolyte acting as an ionic conductor.

A sensor is to be understood as a device for acquiring at least one parameter of the electrochemical cell or battery. This can include devices for detecting electrical variables such as the voltage, current, capacitance or charge, for example, or also the temperature, pressure or even the installed position of the electrochemical cell or battery.

In accordance with a further aspect, a method for the handling and servicing of an electrochemical cell comprising at least one sensor for acquiring parameter data on the electrochemical cell or battery, a storage apparatus preferably having non-volatile memory, particularly a flash memory, and a data transmission unit, is accomplished by the method comprising the following steps: acquiring parameter data on the electrochemical cell or battery respectively, feeding the acquired parameter data to the storage apparatus, reading out the stored parameter data from the storage apparatus to the data transmission unit, and the data transmission unit transmitting the read-out parameter data to a display apparatus, the data transmission unit particularly wirelessly transmitting the read-out parameter data to a display apparatus.

One advantage of this design is that a user is able to readily determine the status of the electrochemical cell or battery respectively from the parameter data, e.g. for handling or servicing purposes, so as to initiate measures for maintaining or increasing the efficiency or safety as needed.

Parameter data is to be understood in the present context not only as a plurality of parameter data, but also, where applicable, one single parameter datum. Accordingly, predetermined parameter values in the present context is not only to be understood as a plurality of predetermined parameter values, but also, where applicable, one single predetermined parameter value.

With the handling and servicing methods, it is preferential for at least one parameter data on the electrochemical cell or battery acquired by the sensor to be selected from among a parameter group which includes at least one of the following parameters: the state of charge (SOC) of the electrochemical cell or battery, the temperature of the electrochemical cell or battery, the voltage of the electrochemical cell or battery, the load on the electrochemical cell or battery, the charging characteristics of the electrochemical cell or battery, the status of a protective apparatus, particularly a PTC resistor or a power cutoff apparatus, the functioning of the sensor or the pressure in the electrochemical cell or battery respectively. One preferential embodiment provides for an algorithm during servicing or periodically which checks and saves the parameters, particularly the operational states such as the temperature, load, charging characteristics and/or the functioning of the protective apparatus and the sensors in or on the electrochemical cell or battery, whereby said data is then locally available if needed without high analytical expense.

Further proven advantageous is for the method to comprise the step: reading out the bar code information associated with the electrochemical cell or battery.

It is particularly preferential for the method to comprise at least one of the steps: activating the electrochemical cell or battery via the data transmission unit as a function of the displayed control data or displayed parameter data respectively, effecting a treatment of the electrochemical cell or battery or releasing the electrochemical cell or battery for transport. One advantage of this method lies in being able to improve the safety and provide a basis for evaluating whether a component might be subject to a ban on being transported or which state, particularly state of charge (SOC), the electrochemical cell or battery is in. In large-scale and small-scale assembly cells, protective apparatus such as PTC resistors or power cutoff apparatus and the like are disposed on the cell contacts, in cells or on or in the battery respectively. Upon or subsequent to being actuated, the cell or the battery may be damaged in a high state of charge so that it is advantageous to be able to draw conclusions as to the specific model of the components, protective apparatus, the testing status of the components which can otherwise only be obtained at great cost in electrical/electrochemical shops or battery institutes. Drawing on the production lot, the provided UN certification of the components and the current data on the components and protective apparatus, the user is able to carry out extensive preliminary prognoses and/or maintenance and/or repairs.

The method can further comprise the step: the electrochemical cell or battery being activated via the data transmission unit as a function of the control data display step and the bar code information read-out step, respectively as a function of the parameter data display step and bar code information read-out step. One advantage of this method is that specific steps can be initiated to improve battery operation efficiency and contribute to the long-term overall efficiency of the system.

It is preferential in the handling and servicing method for at least one parameter data on the electrochemical cell or battery acquired by the sensor to be selected from among a parameter group which includes at least one of the following parameters: the number of previous charging cycles in the electrochemical cell or battery, the characteristics of the previous charging cycles in the electrochemical cell or battery, the capacitance of the electrochemical cell or battery at the last full charge, the original capacitance of the electrochemical cell or battery, the maximum voltage of the electrochemical cell or battery at the last full charge, the original voltage of the electrochemical cell or battery, or the manufacturer of the electrochemical cell or battery.

In accordance with a second aspect, an electrochemical cell having a controller, particularly a cell controller, comprising at least one sensor for acquiring parameter data on the electrochemical cell or a battery respectively, at least one storage apparatus, preferably having non-volatile memory, particularly a flash memory, and at least one signal transmission unit, particularly a wireless signal transmitting unit, is accomplished by the electrochemical cell being designed to perform one of the above-cited methods.

Preferentially, the sensor for the electrochemical cell is designed to acquire parameter data on the electrochemical or on the battery respectively which is selected from among a parameter group comprising at least one of the following parameters: the state of charge of the electrochemical cell or battery, the temperature of the electrochemical cell or battery, the voltage of the electrochemical cell or battery, the load on the electrochemical cell or battery, the charging characteristics of the electrochemical cell or battery, the status of a protective apparatus, particularly a PTC resistor or a power cutoff apparatus, on or in the electrochemical cell or on or in the battery respectively, the functioning of the sensor or the pressure in the electrochemical cell or battery respectively.

The sensor of the electrochemical cell can furthermore comprise at least one of the following sensor units: a state of charge sensor unit, a temperature sensor unit, a voltage sensor unit or a pressure sensor unit.

It has proven advantageous for the storage apparatus to be designed to store at least one of the following parameters: the number of previous charging cycles in the electrochemical cell or battery, the characteristics of the previous charging cycles in the electrochemical cell or battery, the capacitance of the electrochemical cell or battery at the last full load, the original capacitance of the electrochemical cell or battery, the maximum voltage of the electrochemical cell or battery at the last full load, the original voltage of the electrochemical cell or battery, or the manufacturer of the electrochemical cell or battery.

The electrochemical cell can furthermore comprise an activating apparatus which is designed to activate the electrochemical cell or the battery respectively via the wireless signal transmission unit.

The present invention moreover relates to an arrangement of such electrochemical cells designed for use in a motor vehicle. The present invention particularly relates to a battery having a plurality of the above-cited electrochemical cells.

This design has the advantage of preventing damage to the electrochemical cells in the event of improper installation.
