Description

FIELD

Embodiments disclosed herein relate to energy storage systems (ESS), and more particularly but not exclusively, to enhancing and estimating life of ESS.

BACKGROUND

ESS, such as, batteries are used to power systems, such as, electric vehicles, hybrid vehicles and uninterruptible power supply systems, among other systems. Over a period of usage the ESS starts to degrade and results in reduced performance being delivered by the ESS. The degradation of the ESS may be due to various factors, such as, pattern in which the ESS may be used, operating conditions, and improper maintenance of the ESS, among others. Further, in some cases the ESS begins to degrade faster than usual, and if corrective measures are not taken then the life of the ESS is eventually reduced.
Typically, manufacturers provide warranty with respect to performance of the ESS based on the application the ESS is meant to be used. Further, the warranty period is based on the normal working condition of the ESS in the application it is used. Generally, beyond the warranty period the ESS normally do not deliver the desired performance.
The ESS, even though normally do not deliver the performance desired for its initial application after the warrant period, they can be used beyond the warrant period for the same application for some more duration, however with lower performance. Alternatively, the ESS can be used beyond the warrant period for some other application for some more duration, where performance level lower than the initial performance level is satisfactory.
In light of the foregoing discussion, it would be desirable to know the performance the ESS may deliver. Additionally, it would be desirable to enhance the performance that the ESS can deliver and also increase the duration for which the ESS can be used.

Method for Estimating Performance That May be Delivered by ESS 102

FIG. 3 is a flowchart illustrating a method for determining performance (it may be noted that the word ‘performance’ in certain embodiments is used to refer to life of the ESS 102) that may be delivered by the ESS 102, in accordance with an embodiment. At step 302 data corresponding to the ESS 102 is collected. It may be noted that several parameters corresponding to the ESS 102 affect the performance that may be delivered by ESS 102. Hence, to determine the performance that may be delivered by ESS 102, parameters corresponding to the ESS 102 are monitored. Data corresponding to the parameters corresponding to the ESS 102 are collected by the EMS 104. In an embodiment, the EMS 104 collects data in substantially real time. In another embodiment, the data is collected by the EMS 104 at intervals of time. Further, the data collected by the EMS 104 is transmitted to the DPS 106. In an embodiment, the EMS 104 processes the collected data, and transmits the processed data to the DPS 106 through the signal transmitting and receiving device 208. Further, in an embodiment, the EMS 104 transmits all the collected data to the DPS 106. Alternatively, the EMS 104 may transmit collected data partially to the DPS 106.
The data collected from the ESS 102 is used to generate behavioral pattern of the ESS 102, at step 304. The pattern represents the manner in which the ESS 102 has been performing. The pattern can be used to estimate the performance of the ESS 102. To estimate the performance, the behavioral pattern of the ESS 102 is compared with patterns developed using historical data, at step 306. Historical data, such as parameters that are collected from the ESS 102 are collected from similar ESS over a period of time. Using this data, historical patterns are developed corresponding to the behavior of the ESS. Hence, these historical patterns indicate the manner in which ESS would behave corresponding to their behavior. In an embodiment, historical data can also mean data that is used in empirical mathematical models that are used to develop pattern against which behavioral patterns are compared. The patterns developed using empirical mathematical models are herein referred to as historical patterns. At step 306, the behavioral pattern that is developed at step 304 is compared with the historical patterns to identify a historical pattern that is similar to the current behavioral pattern. Once a historical pattern is identified, based on the behavior in the historical pattern, behavior of the ESS 102 is estimated.
The various actions in the aforementioned method can be performed in the order presented, in a different order or simultaneously. Further, in some embodiments, some actions listed in FIG. 3 can be omitted.
In an embodiment, the above method is used to estimate performance of the ESS 102 post warranty period of the ESS 102. Further, in light of the estimated performance, the value of the ESS 102 post warranty period can be calculated. Furthermore, based on the estimation, one can also determine a field in which the ESS 102 may be used post warranty period.
Further, it may be noted that performance may correspond to a number of parameters such as, energy storage capacity, power characteristics, internal impedance, and self-discharge rates, among other parameters.
In an embodiment, the EMS 104, to enable determination of the performance that may be delivered by ESS 102, collects data while the ESS 102 is being charged. When the ESS 102 is charged, the EMS 104 collects from the ESS 102, data corresponding to, state of charge at the beginning and end of the charging cycle, voltage, current, temperature, time, duration of charging and impedance, among other data. Further, additionally or alternatively, during the discharging cycle of the ESS 102, the EMS 104 collects from the ESS 102, data corresponding to, state of charge at the beginning and end of the discharging cycle, voltage, current, energy spend, temperature, time, duration for discharging, and impedance, among other data. Furthermore, additionally or alternatively, during an idle period, when the ESS 102 is neither being charged or discharged due to consumption of energy by ECS 106, the EMS 104 collects from the ESS 102, data corresponding to, state of charge, voltage, duration of idle period, self discharge and temperature, among other data. Additionally, it may be noted that, a person skilled in the art, in light of the disclosed embodiments, can enable collection of some or all of the aforementioned data, or can also enable collection of any additional data to enable determination of performance that may be delivered by ESS 102. Such modification would be within the scope of this invention.
The parameters that are collected represent the condition under which the ESS 102 is operated. The operating condition will have an effect on the performance of the ESS 102. Hence, data representing the operating conditions is collected to determine the performance that may be delivered by ESS 102. FIG. 4 illustrates an exemplary graph of affect of operating temperature on capacity of the ESS 102, in accordance with an embodiment. In the graph, line 402 represents change in capacity of the ESS 102 that is operated at 25° C., and line 404 represents change in capacity of the ESS 102 that is operated at 45° C. Further, lines 406 and 408 refer to 100% and 80% ESS 102 capacity, respectively. Furthermore, points 412 and 410 refer to life in cycles of usage of ESS 102 or years of usage of ESS 102, at which capacity of ESS 102 that is operated at 25° C. and 45° C. decreases to 80%, respectively. It can be observed that, capacity of the ESS 102 that is operated at 45° C. decrease to 80% earlier when compared to the ESS 102 that is operated at 25° C. Such effect on the performance is used to determine the performance of the ESS 102.
As aforementioned, another operating condition that affects the performance of the ESS 102 is operating condition during idle period. FIG. 5 illustrates an exemplary graph of affect of state of charge during idle period on life of the ESS 102, in accordance with an embodiment. The graph represents the effect of state of charge at which the ESS 102 is maintained during idle period, on calendar life of the ESS. As it can be seen in the graph, the calendar life of the ESS 102 which is maintained at 50% state of charge during idle period would be the highest. While determining the performance of the ESS 102, such effects are taken into consideration.
In an embodiment, in light of determination of performance and life of the ESS 102, post warranty period, based on the degradation of the ESS 102, the user of the ESS may be charged an appropriate fee. In some embodiments wherein the ESS 102 or the energy system 110 is taken on lease, while determining the compensation to be paid by the user, the extent to which the ESS 102 is degraded is also considered.
In another embodiment, based on the degradation of the ESS 102, the value of the ESS 102 is determined.
In an embodiment, the ESS 102 may be applied in a infrastructure wherein the ESS 102 is configured to electrically communicate with a grid, and supply electricity to the grid or store electricity supplied from a grid (ex: Vehicle to grid infrastructure). Using the ESS 102 in the aforementioned infrastructure may affect the performance of the ESS 102. In certain cases the ESS 102 might get degraded faster. To determine the performance/degradation of the ESS 102, the above discussed method and system are used. Further, based on the estimation made, the price at which electricity is supplied to the grid from the ESS 102 can be determined. Additionally or alternatively, one can also decide, based on the estimate, whether to use or not to use the ESS 102 in the aforementioned infrastructure.
In an embodiment, as recited earlier, historical patterns can be developed using mathematical models. It may be noted that mathematical or other models can be used in a number of ways, independently or in conjunction with empirical data (ex: data collected from similar ESS over a period of time) to develop patterns for comparison. For example, in an embodiment, a model a specific set of parameters may be used to develop a historical pattern for comparison or to estimate the ESS 102 performance degradation based on short-term or long-term usage pattern. In another embodiment, a model may be used with one or more variable parameters to fit to existing empirical data, and also further to extrapolate empirical data to a later time, to develop a historical pattern for comparison. In yet another embodiment, a model may be used to scale existing empirical data to different conditions. Scaling of empirical date to other conditions may be done if empirical data does not exist at identical conditions and scaled empirical data is considered more accurate than pure model-generated data. For example, scaling of empirical data may be done in a situation where, a ESS is operated in a way that is similar to that of existing empirical data but with some differences in the operating condition, such as, operating at a different temperature or operating at a different depth of discharge, and it is believed that the effects of the parameters that are different are accurately represented by the model. The model can be fit to the existing empirical data from similar ESS and situations, following which the relevant parameters can be altered and the model used to develop patterns under the new conditions. In another embodiment, a model may be used to disaggregate the lifetime effects of varying operating conditions and usage patterns over time. For example, if empirical data exists for the capacity degradation over a usage period of an ESS, which was operated in a variety of ways during that period, a model with parameters set appropriately for each different operating condition for the relevant amount of usage can be used to estimate what fraction of the capacity degradation resulted from each operating mode or each short-term event, even if the model would not be considered accurate enough to estimate these absolute degradations by itself. In another embodiment, a model may be used to aggregate the lifetime effects of varying operating conditions and usage patterns over time. For example, if empirical data exists from a number of similar ESS operating in different ways, and a model is fit to each of them with the differences in operating modes appropriately represented as different values of the appropriate parameters, the model can then be used to estimate the lifetime effects on an ESS operated in different modes over time.

Method of Enhancing Performance that the ESS 102 Can Deliver

FIG. 6 is a flow chart illustrating a method for enhancing performance/life of the ESS 102, in accordance with an embodiment. At step 602, the DPS 106 and/or the EMS 104 identify adaptations that can be made to enhance the performance/life of the ESS 102. Further, if any adaptations can be made to enhance the performance/life of the ESS 102, post warranty period, then such adaptations are made at step 604. In an embodiment, after identifying the adaptations that can be made to enhance the performance/life of the ESS 102, the DPS 106 or the EMS 104 determines whether such adaptations affects the performance of the ESS 102 or performance of systems that are dependent on the ESS. Thereafter, if it is determined that performance of the ESS 102 or any dependent systems may get affected, then user of the ESS 102 is informed about the same, and adaptations are made based on the command of the user. In an embodiment, prior to making any adaptations, the user's permission is sought. Alternatively, adaptations can be made without taking user's permission.
In an embodiment, before identify adaptations that can be made to enhance the performance/life of the ESS 102, an estimation of the performance that may be delivered by the ESS 102 is made.
FIG. 7 illustrates an adaptation that is made to the ESS 102, in accordance with an embodiment. The adaptation is made in light of ESS 102 charge and discharge pattern that is illustrated in FIG. 8. In light of FIG. 8, it is can be seen that user of the ESS 102 has a habit of charging the ESS 102 everyday but using the car which is powered by the ESS 102 only on weekends. His usage pattern shows that the car is kept idle on full charge over most parts of the week. As seen in FIG. 5 this has an effect of reducing the life of the ESS 102. The life of the ESS 102 can be enhanced if the ESS 102 is maintained at about 50% state of charge during the idle period.
To enhance the performance/life of the ESS 102, the charging regime of the ESS 102 is adjusted such that the charge level during the idle period is limited to a percentage that enhances the life.
FIG. 7 depicts a new charging regime. The DPS 106 or the EMS 104 ensures that the ESS 102 gets charged to about 50%. Further, DPS 106 or the EMS 104 ensures that charging is initiated such that ESS 102 gets charged completely on late Saturday before the user needs to use the car. The ESS 102 life is thus enhanced without compromising usage requirements.
In light of the foregoing discussion, it will be clear to a person with ordinary skill in the art that power usage pattern and storage temperature pattern can also be adjusted to enhance the performance/life of the ESS 102.
In an embodiment, the ESS 102 may be rented out and the compensation to be paid for taking the ESS 102 on rent can be determined based on the estimation of performance/life of the ESS 102. When the ESS 102 is being used while it is rented, data corresponding to the ESS 102 is, collected. The data that is collected is used to generate behavioral pattern of the ESS 102 and the same is used for estimating performance/life of the ESS 102. Based on this estimation, if the usage of ESS 102 is such that the performance/life of the ESS 102 is increased, then the rent is reduced by certain factors. Alternatively, if the usage of ESS 102 is such that the performance/life of the ESS 102 is decreased, then the rent is increased by certain factors. In an embodiment, the user may be allowed to reduce the rent for the ESS 102 by allowing adaptations to be made to the ESS 102 that would enhance the performance/life of the ESS 102.
The embodiments disclosed herein can be implemented through at least one software program running on at least one hardware device and performing network management functions to control the network elements.
