Description

Energy Storage System Monitoring and Protection System The present disclosure relates to systems and methods for the monitoring and protection of Energy Storage Systems (ESS), used for the storage of electrical energy, against the risk of overheating, thermal runaway, and/or discharge of combustible gases.
Battery packs are used in increasing amounts for storage of electrical energy.
One of the risks involved with the use of such battery packs is overheating of the batteries. Overheating may occur as a result of external causes, internal damage or overcharging. Overheating can lead to high internal energy loss, leading to over-pressurisation and discharge of volatile, hazardous and/or combustible gases.
Prior art monitoring systems have detected discharge of hazardous gases but do not prevent or suppress the process leading up to such discharge By this time significant and costly damage has typically occurred.
The present invention arose in a bid to provide an improved system, in particular a system capable of preventing or suppressing the process leading up to the discharge of gases.
Representative features are set out in the following clauses, which stand alone or may be combined, in any combination, with one or more features disclosed
in the text and/or drawings of the specification.
According to the present invention in a first aspect, there is provided a system for the monitoring and protection of an energy storage system comprising a plurality of energy cells, the monitoring and protection system comprising: at least one temperature sensor; a suppression agent discharge system for discharging a suppression agent in the vicinity of the energy cells; and a control system for constantly monitoring the rate of change of temperature measured by each of the at least one temperature sensor, and for controlling the discharge of the suppression agent from the suppression agent discharge system, wherein the control system is arranged to trigger a discharge of the suppression agent by the suppression agent discharge system upon detection of a rate of increase of temperature by the at least one temperature sensor above a predetermined maximum permitted rate of increase.
The term energy cell as used herein covers battery packs, fuel cells and alternative electrical energy storage means. It may in some contexts cover individual cells within battery packs.
According to the present invention in a further aspect, there is provided a method of monitoring and protecting energy storage systems using the system defined above.
Further, preferable, features are presented in the dependent claims.
Non-limiting embodiments of the invention will now be discussed with reference to the following drawings: Figure 1 shows a schematic plan view of a system according to an embodiment of the present invention; and Figure 2 shows a sensor arrangement for use in embodiments of the present invention.
It must be noted that whilst the detailed description that follows focusses on the monitoring and protection of battery packs, the disclosed arrangements and any discussed alternatives may be used in respect of the monitoring and protection of individual battery cells and further alternative energy storage systems, including but not limited to such systems utilising fuel cells or otherwise, as will be readily appreciated by those skilled in the art.
With reference to Figures 1 and 2, there is shown, schematically, a system 1 for the monitoring and protection of an energy storage system that comprises a plurality of battery packs 2. As may be seen, the monitoring and protection system 1 comprises at least one temperature sensor 3, a suppression agent discharge system 4 and a control system 5. The suppression agent discharge system 4 is arranged to discharge the suppression agent. It discharges the suppression agent in the vicinity of the energy cells 2. The control system 5 is arranged to constantly monitor the rate of change of temperature measured by each of the one or more temperature sensors 3 and to control the discharge of the suppression agent from the suppression agent discharge system 4. The control system 5 is arranged to trigger a discharge of the suppression agent by the suppression agent discharge system 4 upon detection of a rate of increase of temperature by the one or more of the temperature sensors 3 113 above a predetermined maximum permitted rate of increase.
The system may be arranged such that the control system 5 activates an alarm sequence that is dependent on the detected rate of rise of temperature, detected temperature and/or oxygen level, following initial activation. In addition to providing cooling, the system may be configured to provide additional ventilation and/or inerting of the air around the energy cells to dilute any emitted hazardous gases to a safer level and prevent combustion of the gases, as discussed in greater detail below.
The control system may have set points for temperatures or rates of increase of temperature which would incur pre-alarm, alarm and activation conditions. In addition, as mentioned, there can be a variable output to control the mass/volume of the suppressing agent based on the rate of rise of temperature, the temperature, and/or the sensed oxygen level. Note that the variable output may increase or reduce the flow rate of the suppression agent in dependence on any of these factors or any combination of these factors The suppression agent preferably comprises an inert gas. The suppression agent may comprise carbon dioxide, nitrogen, Argon, HFC125, HFC227ea, FK-5-1- 12, or mixtures thereof. As will be appreciated by those skilled in the art, the suppression agent may be selected to suit the needs of the system as configured and in particular in dependence on the type of energy cells to be monitored/protected.
It is preferable that the at least one temperature sensor 3 is arranged to monitor the temperature in the vicinity of each of the energy cells. As discussed, the energy cells 2 in the disclosed arrangement comprise battery packs. The battery packs 2 may be arranged in racks 8, as seen in Figure 2. They may of course be arranged other than in racks and there may be more or less battery packs than are shown in the figures. The system 1 is fully adaptable and scalable. The at least one temperature sensor 3 may be immediately adjacent to each of the battery packs. It may be directly on top of each of the battery packs. It may be in direct contact with each of the battery packs. In the depicted arrangement, as seen in Figure 2, the at least one temperature sensor 3 may comprise one or more linear thermal detectors that are provided in sleeves 7 and are provided on top of the battery packs 2. The linear thermal detectors in the sleeve may be attached to the battery packs 2.
In alternative arrangements, rather than the at least one temperature sensor 3 comprising one or more linear thermal detectors, there may be provided a plurality of separate temperature sensors, wherein each temperature sensor is associated with a single respective one of the battery packs, such that the rate of rise of temperature of each individual battery pack may be monitored independently. Such an arrangement may be implemented in combination with an agent discharge system 4 that allows for controlled localised discharge of the suppression agent, at least initially following activation.
It is preferable that the system 1 further comprises at least one gas detection sensor 6 connected to the control system 5 for detecting gas released by the battery packs 2. The at least one gas detection sensor is preferably arranged to monitor for gas in the vicinity of each of the battery packs 2. In the depicted arrangement, the at least one gas detection sensor 6 comprises a tubular aspirating gas detector. Each of the tubular aspirating gas detectors may be provided with one of the linear thermal detectors in one of the sleeves 7. Each of the tubular aspirating gas detectors may thereby be mounted in the manner of the one or more temperature sensors 3, as discussed above.
As will be appreciated by those skilled in the art, the at least one gas detection sensor 6 is not limited to a tubular aspirating gas detector and may take various alternative forms. Moreover, as discussed in respect of the at least one temperature sensor 3, there may be a plurality of gas detection sensors, wherein each gas detection sensor is associated with a single respective one of the battery packs, such that the release of gas from each individual battery pack may be detected independently. This may feed into the provision of an arrangement of the agent discharge system 4 that allows for controlled localised discharge of the suppression agent, at least initially following activation, as mentioned above.
The control system 5 is preferably configured to discharge the suppression agent at a first rate when there is no detection of released gas, and at a second, increased, rate when there is a detection of released gas. The rate of discharge of the suppression agent may additionally or alternatively be varied in dependence on the measured temperature, the measured rate of rise of temperature and/or the sensed oxygen level as discussed below.
The system preferably further comprises at least one oxygen sensor connected to the control system 5. The oxygen sensor may be integral with the gas detection sensor 6. The disclosed tubular aspirating gas detector may, in this case, both monitor for the release of gas and monitor oxygen levels.
With the preferred monitoring of oxygen levels, the control system may be configured to vary the rate of discharge of the suppression agent in dependence on the sensed oxygen level. The system may be configured such that following activation, the sensed oxygen level is reduced to a level below a predetermined level in the proximity of the energy cells and is subsequently maintained below that level. The predetermined level may be dependent on the form of the energy cells. It may be 13% or less.
As is preferred, in the present arrangement the suppression agent discharge system 4 comprises one or more pressure vessels, a main on/off valve 4b, a mass/flow regulating valve 4c and a distribution network 4a consisting of a tubular grid with nozzles (not shown) discharging in between or underneath the battery packs, to provide cooling and inerting of the environment immediately surrounding the battery packs. The arrangement may be such that each battery pack has a nozzle provided directly beneath it. Numerous alternative suppression agent discharge system configurations will, however, be possible as will be readily appreciated by those skilled in the art.
The present invention is particularly useful in controlling the environment surrounding energy cells. The energy cells may be provided in a substantially closed space 100, which may take numerous different forms. The space may, for example, be a room, a standalone unit, or a compartment of a vehicle There may additionally be provided a ventilation system 9 connected to the control system 5 for ventilating the space 100. In the present arrangement the ventilation system comprises a plurality of smoke control dampers 10a, 10b. The smoke control dampers preferably comprise fans. A first smoke control damper 10a may be provided to draw in air. It may be provided at a low level. A second smoke control damper 10b may be provided to expel air and gases. It may be provided at a high level. The configuration and number of smoke control dampers is not particularly limited, as will be appreciated by those skilled in the art.
In some arrangements, there may be one or more smoke control dampers that are connected to the suppression agent discharge system 4. In such case, there may or may not be provided the distribution network 4a, as described above. Without the distribution network 4a, one or more smoke control dampers would alone provide the means of introducing the suppression agent.
The system may further comprise a liquid based extinguishing system 11, which comprises a valve lla under control of the control system 5. The liquid may be water. There may be provided one or more sprinklers or nozzles of conventional form. The control system 5 may be arranged to activate the liquid based extinguishing system in the event the readings from the temperature sensors 3 indicate there is a thermal runaway. The liquid based extinguishing system 11 may be activated simultaneously with the agent discharge system 4 or subsequently.
The control system 5 may be configured to communicate with additional systems. It may be arranged to communicate with external monitor or alarm systems to provide updates of status. The control system 5 may have a manual control for activating or deactivating the system. The manual control can allow for an emergency override.
The described system can have various iterations with detection and discharge systems. The energy cells can comprise Li-ion cells, Lead-acid batteries, hydrogen fuel cells and other high energy storage technologies.
Numerous alternative arrangements and modifications to the system as described herein will be readily appreciated by those skilled in the art within the scope of the appended claims.
When used in this specification and claims, the terms "comprises" and "comprising" and variations thereof mean that the specified features, steps or integers are included. The terms are not to be interpreted to exclude the presence of other features, steps or components.
The features disclosed in the foregoing description, or the following claims, or the accompanying drawings, expressed in their specific forms or in terms of a means for performing the disclosed function, or a method or process for attaining the disclosed result, as appropriate, may, separately, or in any combination of such features, be utilised for realising the invention in diverse forms thereof.
Although certain example embodiments of the invention have been described, the scope of the appended claims is not intended to be limited solely to these embodiments. The claims are to be construed literally, purposively, and/or to encompass equivalents.
