[0001] DESCRIPTION

[0002] A DAMAGE PREDICTION SYSTEM

[0003] Technical Field

[0004] The present invention relates to a damage prediction system which enables the resistance of the cooling plates to be measured instantaneously by means of a coating on the cooling plates, and the damage status and damages that may occur in the future to be predicted depending on predefined resistance values.

[0005] Background of the Invention

[0006] Lithium-ion batteries are used in electric vehicles, portable electronic devices, renewable energy storage systems and in many other applications. The efficiency, safety and lifetime of battery packs are of critical importance to control the temperature and cooling of the cells they comprise. Lithium-ion batteries play a fundamental role in the performance and safety of electric vehicles. Efficient and reliable operation of these systems is of critical importance for the widespread adoption of electric vehicle technology. However, leaks caused by damage to the cooling plates used in the cooling systems of battery systems can both adversely affect the performance of the battery and compromise vehicle safety. In conventional cooling systems used today, leaks can often be detected later and can cause serious problems when intervention is delayed. Detecting these leaks before they occur and informing the end user and technical services when damage may occur is of great importance to prevent major damage. For this reason, today, there is a need for solutions that enable precautions to be taken in advance by predicting the damage status of the cooling plates.

[0007] The Japanese patent document no. JP2022181011A, an application included in the state of the art, discloses a battery cooling system that reduces damage byelectrode coating. The invention subject to the said Japanese patent document aims to provide a technique that reduces the damage applied to the battery by an electrode layer. The respective battery unit consists of a battery module in which a plurality of electrode sheets are laminated along a first direction; and a cooling plate which is arranged so as to be overlapped onto a front surface of the battery module. Each electrode sheet comprises a coated part having an active material on at least one front surface; and an uncoated part adjacent to the coating part and having no active material on both sides of them. The cooling plate comprises a body plate that is opposite to the coated part and cools the battery module; and at least one sensor holder that is attached along an outer edge of the body plate and holds a sensor for detecting information related to the battery module. In the battery unit, a boundary between the coated part and the uncoated part in each electrode sheet and a boundary between the body plate and the sensor holder on a contact surface of the cooling plate are not overlapped in a section extended in parallel with each other in view along a first direction.

[0008] Summary of the Invention

[0009] An object of the present invention is to realize a damage prediction system which enables the resistance of the cooling plates to be measured instantaneously by means of a coating on the cooling plates, and the damage status and damages that may occur in the future to be predicted depending on predefined resistance values.

[0017] An inventive system (1) which enables the damage status of cooling plates and damages that may occur in the future to be predicted comprises;

[0018] at least one cooling plate (2) which is coated with a mixture comprising carbon nanotubes and comprises, at the ends thereof, at least two electrodes (3) configured to enable voltage and current to be applied and electrical resistance changes occurring after voltage and current application to be shared; and

[0020] The cooling plate (2) included in the inventive system (1) comprises two electrodes (3), one at each end, and is configured to exchange data with the processing unit through the electrodes (3). The cooling plate (2) is configured to share with the processing unit (4) data on changes in electrical resistance that occur after the voltage and current applied through the electrodes (3). The cooling plates (2) provide data to the processing unit (4) about the electrical resistance changes occurring thereon, the temperature changes and possible damages of theplates. Surface is protected by the coating comprising nanotubes on the cooling plate (2) and its thermal conductivity properties are increased.

[0021] The processing unit (4) included in the inventive system (1) is configured to be in communication with the cooling plate (2); to apply voltage and current through the said communication; to monitor in real time the electrical resistance changes occurring after the applied voltage and current; to keep a record of the data; and to generate predictions about the health and damage status of the battery by analyzing the data. The processing unit (4) is configured to analyze resistance change data of the cooling plates (2) in comparison with predefined resistance values; to use algorithms for damage detection; and to obtain information on the health status of each cooling plate (2).

[0023] By means of the inventive system (1), damage on the battery pack cooling plates (2) can be detected early. For this, the resistance changes of the cooling plates (2) are monitored and their internal damage is tried to be predicted by comparing them with historical data, thus unexpected failures are prevented. At the same time, the processing unit (4) enables future damages to be predicted by associating potential damages to the plates with a future date by using data analysis and algorithms. In this way, costs are reduced by planning maintenance.Within these basic concepts; it is possible to develop various embodiments of the inventive “A Damage Prediction System (1)”; the invention cannot be limited to examples disclosed herein and it is essentially according to claims.
