CROSS-REFERENCE TO RELATED APPLICATIONS AND PRIORITY
The present application claims priority from the Indian provisional patent application, having application number 202241051346, filed on 08th January 2023, incorporated herein by a reference.
TECHNICAL FIELD
The present disclosure relates to the field of conditioning stations for conditioning an electric vehicle or an energy storage system. More specifically, the present specification relates to a conditioning fluid circuit embedded in a conditioning station for an electric vehicle or an energy storage system. More particularly, the present application discloses a system and a method for cleaning the conditioning fluid circuit of the conditioning station.
BACKGROUND
The subject matter discussed in the background section should not be assumed to be prior art merely as a result of its mention in the background section. Similarly, a problem mentioned in the background section or associated with the subject matter of the background section should not be assumed to have been previously recognized in the prior art. The subject matter in the background section merely represents different approaches, which in and of themselves may also correspond to implementations of the claimed technology.
In the field of conditioning stations, preferably for electric vehicles (EVs), thermal management makes it possible to not only improve the power of the energy storage system but also the longevity of the energy storage system and the performance of the electric vehicle. Therefore, for sustaining an energy storage system’s efficient peak performance, separately or for an EV, the modern conditioning stations have been embedded with a conditioning fluid circuit that maintains the optimum working temperature of the energy storage system while conditioning.
The aforementioned process of maintaining the optimum working temperature of the energy storage system may be termed ‘conditioning of the energy storage system. Now, this process further incorporates a conditioning fluid that may be used for either raising or reducing the temperature of the energy storage system. Depending on the instant temperature of the energy storage system, the conditioning process may be performed at any required time such as before conditioning, while conditioning, after conditioning, or the moment the energy storage system is connected to the conditioning station till the conditioning is complete and the energy storage system is at required optimum temperature.
The conditioning of the energy storage system via the conditioning station is the essential process responsible for managing and/or dissipating the heat generated during the electrochemical processes occurring in the energy storage system while conditioning and/or while the conditioning has to be initiated or finished, thus, allowing the energy storage system to operate safely and efficiently. This helps in preventing the accelerated deterioration of the energy storage system by managing the heat generated by its components so that it operates continuously under optimum temperature conditions.
Although the existing commercially available conditioning stations incorporate a conditioning fluid circuit for conditioning the energy storage system, however, the chances are extremely high that the conditioning fluid circuit may leak and/or get blocked due to various reasons. One of the most concerning reasons for the deterioration of the conditioning fluid circuit is the conditioning fluid itself. As the conditioning fluid travels through the thermal management system of the energy storage system and/or the conditioning station, it gets heated or cooled to extreme temperatures and loses its original chemical properties becoming harmful to the conditioning station components. While flowing through the thermal management system of the energy storage system, the conditioning fluid also takes impurities/debris from the conditioning fluid passages of the thermal management system of the energy storage system, which in turn gets travelled and deposited into the conditioning fluid circuit of the conditioning station and damage the components and conditioning fluid passages of the conditioning fluid circuit. Further, as the chemical and/or the physical characteristics of the conditioning fluid change over a period of time, it leads to the corrosion of the conditioning fluid passages. Thus, the conditioning fluid, after some usage, gets chemically/physically unstable driving impurities to the conditioning fluid circuit and leading to the conditioning fluid circuit failure, ultimately affecting the conditioning station efficiency.
Now, as mentioned above, the cleaning of the conditioning fluid circuit becomes of the utmost importance for maintaining the conditioning station working at its optimum effectiveness. For this, as known in the conventional art, the conditioning fluid circuit is dismantled, and its components and conditioning fluid passages are cleaned separately and then the conditioning fluid circuit is assembled again with the required sealing. Most of the time, some components like parts of the conditioning fluid passages, etc. are replaced with new ones while assembling the conditioning fluid circuit. This increases effort as well as wastage of conditioning fluid circuit components. Further, to reduce such wastage, conventionally, the conditioning fluid is changed within a short period. This might help in delaying the decay of the conditioning fluid circuit, but this also leads to deterioration of the conditioning fluid circuit in the longer run. It is also not commercially feasible to keep changing the conditioning fluid every now and then. Moreover, as known in the art, the process of conditioning the energy storage system and cleaning the conditioning fluid circuit are separate, which leads to a reduced usage time for the conditioning station. Thus, the conventional systems and methods for cleaning the conditioning fluid circuit of the conditioning station are not efficient both practically and commercially.
Thus, there is this long-standing need for an efficient cleaning system for a conditioning fluid circuit of a conditioning station so as to preserve and improve the efficacy of the conditioning station in conditioning the energy storage system and maintaining the energy storage system at its optimum temperature.
