Definitions
- the invention relates to a cycle testing method for at least one rechargeable battery.
- a battery may be for example a NiCD battery, a NiMH or lithium-ion battery.
- Other batteries are also possible.
- Such batteries are used for example for single-battery emergency lights, which may be part of a corresponding emergency lighting system.
- the respective luminaire has, as a luminous means, one or more fluorescent tubes, LEDs or the like, possibly also in modular construction.
- the battery is on site, i. near the appropriate load, connected to a power supply to at least charge the battery.
- the invention relates to the automation of the formation.
- a first step i) the battery is charged by means of the supply device to 100%.
- the charging is interrupted for a particular predetermined time in a step ii) to lower a temperature of the battery.
- a certain amount of energy is usually converted into heat, which is dissipated in this way.
- step iii) After interrupting the charging for the predetermined time takes place in a step iii) discharging the battery to the discharge end voltage. Subsequently, the foregoing steps i) to iii) of loading, interrupting charging, and discharging are repeated, i. performed several times.
- This cycle test procedure forms a new battery and optimizes the capacity of the battery.
- the battery is monitored at all times.
- NiCd and NiMH cells are charged with a constant current depending on the battery temperature.
- the maximum charging voltage is monitored.
- a trickle charge is switched to balance the self-discharge of the cells. For lithium batteries up to a max. Charging voltage charged and then completely shut off the charge. The charge is switched on again when the voltage of the lithium battery falls below a certain value and the capacity has fallen below a certain value, which could jeopardize the emergency light duration.
- the battery in a separate housing and to connect it with the load, in particular explosion-proof.
- the battery and the corresponding housing can be used in potentially explosive areas; the corresponding contact between the housing and the load can be made, for example, via Ex-d plug contacts or the like.
- the supply device may be designed in the required explosion protection.
- the supply unit can also be used in potentially explosive areas and, similar to the battery, can be exchanged with its housing, if necessary.
- step i) number of batteries and / or types of batteries are detected. This detection is usually carried out by the supply unit, so that different numbers of batteries or even different types can be charged or discharged by only one supply unit and can also be subjected to the cycle test procedure.
- Such a critical situation is given, for example, when an emergency supply time of the load by the battery is less than a predetermined emergency supply minimum time. This can occur, for example, with NiCd batteries when a so-called memory effect occurs or when batteries have not been discharged for a longer period of time until the final discharge voltage.
- the corresponding steps of the cycle test method may be performed after detecting this too short emergency supply time. That is, it is attempted by the cycle test method to regenerate the battery again so far that it can be used for emergency supply.
- the corresponding "self-healing" of the battery is achieved by discharging the battery to the final discharge voltage.
- the circuit has a redundant deep discharge protection, which reliably prevents destruction of the batteries by discharging below the discharge end voltage.
- the corresponding cycle of the test procedure is carried out several times in a predetermined number. If, after completion of the cycle test procedure, a corresponding emergency supply minimum time is again reached by the battery, the battery is switched to reuse for supplying the load in normal operation. That is, the battery again reaches the required discharge time and thus emergency supply minimum time and the corresponding critical situation is eliminated. The normal operation of the load and in particular the single-battery emergency light can be resumed.
- the cycle test method can be performed one more time or more times.
- an error message can be output by means of, for example, a display device of the supply device. This informs the user of the malfunction of the battery.
- such an error message can be displayed if, after the corresponding steps of the cycle test procedure, at least one battery parameter is outside a predetermined range. This can also be determined by the supply unit.
- the corresponding cycle test procedure for forming the battery should only be initiated when the mains voltage was continuously present for a certain period of time.
- the corresponding supply device of the battery may have different components.
- the supply unit is designed, for example, with a charging device for the battery and / or a processor and / or a constant current source and / or a display device and / or a battery monitor and the like.
- the supply device can be used to charge, discharge, monitor and store all battery parameters and the like.
- the supply unit can then carry out a cycle test if, for example, in the case of a fully charged battery in emergency lighting mode, a supply of the corresponding load for the specified emergency supply minimum time is no longer guaranteed.
- the supply unit also for the corresponding supply of the connected load, see for example an electronic ballast for a fluorescent lamp or an LED module.
- supply unit and electronic ballast are separate components.
- the corresponding cycle is controlled by the processor of the supply device. That is, the processor also monitors, for example, the charge of the battery via a corresponding constant current from the constant current source.
- An easy way to load is a capacity dependent load. With such charging, charging can take place to a full capacity of the battery, in particular taking into account a charging factor of the battery. Such a charging factor corresponds to the reciprocal of a charging efficiency. The charging efficiency corresponds to the ratio of the withdrawn capacity to the supplied capacity.
- the charging factors are known for different battery types. For example, the charging factor for NiCd batteries is approximately 1, 4 and for NiMH batteries approximately 1, 2.
- the charge factor, the charging current and the maximum charge quantity can also be used to determine the approximate charging time of the battery.
- the battery can be discharged in particular via the load. It may also be advantageous if there is a separation of the mains voltage from the electronic ballast for supplying a fluorescent lamp or an LED module as a load during discharge and a supply of the ECG via a particular push-pull converter from the battery forth.
- a push-pull converter is a circuit that converts a DC electrical voltage into another DC electrical voltage.
- Figure 1 is a simplified schematic representation of a circuit for performing the cycle test method and Figure 2 graphs of current, voltage and temperature, especially during the cycle test procedure.
- FIG. 1 shows a greatly simplified sketch of a corresponding circuit arrangement for carrying out the cycle test method according to the invention.
- the circuit comprises at least one rechargeable battery 1 or several of these.
- the battery or batteries 1 are arranged in a housing 4, in which optionally also a display device 15 is integrated. This can be connected to a supply unit 3 in a luminaire via appropriate explosion-protected contacts, for example, according to explosion protection Ex-d connectable.
- a supply unit 3 in a luminaire via appropriate explosion-protected contacts, for example, according to explosion protection Ex-d connectable.
- the battery or batteries 1 are connected to a supply unit 3. This makes the battery rechargeable and monitorable. In particular, such charging, discharging and monitoring takes place during the cycle test method according to the invention.
- the supply unit 3 has in the illustrated embodiment, various components.
- a component is, for example, a charging device 12, which carries out the charging of the respective battery 1 from the mains voltage 16 ago.
- the supply unit 3 has a battery monitor 19, a constant current source 14 and a processor 13.
- the charging of the respective battery 1 by means of the charging device 12 from the constant current source 14 can be monitored by the processor 13.
- the processor 13 can also control and monitor the discharge of the respective battery 1, in particular via the load 2 and optionally the electronic ballast 17.
- the charging of the respective battery is dependent on the capacity.
- the load 2 may be an emergency light, which has as a light source, for example, a fluorescent lamp, an LED module or the like.
- the electronic ballast 17 may be used to control the light source.
- At least the battery 1 may be associated with a temperature measuring device 20 in order to carry out charging or discharging of the battery as a function of charging current, charging voltage and temperature by means of the supply device 3 and in particular of the processor 13.
- FIG. 2 shows various diagrams for current 7, voltage 8 and temperature 9 both before carrying out the cycle test method according to the invention and during, for example, three cycles, see cycle 10.
- the temperature 9 increases initially when fully charged the battery to an elevated temperature, which then drops to a substantially constant temperature.
- a first cycle is run after the battery has an inadmissible value by monitoring the supply device in a battery parameter.
- the cycle takes place during initial commissioning after the mains voltage has been applied to the supply unit for a certain time.
- the battery is first charged via the supply unit.
- the charging takes place in particular via a constant current and capacity-dependent. Charging will continue until full capacity.
- Subsequent to the charging takes place an interruption 21 of the store for a predetermined time and then a discharge, in particular to deep discharge.
- the cycle is carried out again, see Loading, interrupting the charging, and discharging to deep discharge 1 1.
- Such a cycle 10 can be carried out two, three or even several times in succession. If it is determined at the end of the cycle test procedure that a corresponding "self-healing" of the battery has taken place, a return to normal operation and use of the battery is again in the emergency lighting system.
- the supply unit 3 has a charging device 12 with a constant current source 14. Discharging takes place via the connected load 2 and optionally via ballast 17.
- the mains voltage 16 is separated from the ballast 17 and this supplied via the push-pull converter 18 from the battery forth.
- the control usually takes place via the processor 13.
- a simple circuit results for carrying out a cycle test method by which a battery or a plurality of batteries is monitored and in the event of a malfunction and in particular a decreasing capacity of the battery, the battery is improved in terms of their Notumpssmindestzeit so far that it can be used again in an emergency lighting system in normal operation.
- the described cycle is carried out once and usually several times. This leads to a "self-healing" of the battery.In addition, with a non-recoverable error of the battery, the corresponding malfunction of the battery can be displayed.
