摘要： A deterioration estimation apparatus includes a storage processing unit and a calculation unit. The storage processing unit acquires a plurality of models from a model generation apparatus, and stores the models in a model storage unit. A plurality of models are generated by performing machine-learning on training data, the training data using, as input values, measurement data for training indicating a result of measuring a state of a storage battery when the number of charge and discharge times is αi to αj (where j≥i), and using, as a target value, SOH indicating a deterioration state of the storage battery when the number of charge and discharge times is β (where β>αj). The calculation unit uses a plurality of models stored in a model storage unit to calculate an estimation result of transition of SOH of a storage battery managed by the deterioration estimation apparatus.

摘要： Disclosed is a method for producing a sensor and a battery pressure detecting sensor produced thereby, which operate in a short mode when a pressure of a standard level or more is applied, thereby preventing the breakage and ignition of a battery due to swelling. The disclosed battery pressure detecting sensor disposes a membrane sheet formed with a first accommodation hole under a conductive sheet, has a part of the conductive sheet connected to a first terminal through a first accommodation hole, and has the membrane sheet connected to a second terminal.

摘要： A method and system for monitoring a non-rechargeable battery of an IoT device are described. Voltage values of the non-rechargeable battery when a load is applied to the non-rechargeable battery are determined over a first interval of time. Based at least in part on these voltage values a determination of whether a voltage of the non-rechargeable battery has decreased for more than a predetermined threshold is performed. In response to determining based at least in part on the voltage values that the voltage of the non-rechargeable battery has decreased for more than the predetermined threshold, a prediction of an end of life parameter value for the non-rechargeable battery is performed, and the end of life parameter value is transmitted to an electronic device of an administrator of the IoT device.

摘要： A used secondary battery module management system server manages a manufacture of a battery assembly. The server stores, in a memory, a correspondence relationship of each of secondary battery modules among identification information, ranks, and status information. The server extracts an available rank from the ranks in response to a rebuilding request for the battery assembly. The available rank is a rank in which the number of the secondary battery modules having the status information indicating that the secondary battery modules are available is equal to or larger than the number of the secondary battery modules required to constitute the battery assembly. The server receives, from an external terminal, the identification information on each of selection secondary battery modules having an identical rank.

摘要： Disclosed herein is a method for predicting the performance characteristics of a Li-ion battery over the course of the lifetime of the battery. A model based on integration of a set of ordinary differential equations is used to predict the voltage and thermal characteristics of the battery in a short period of time and a universal ordinary differential equation is used to predict the degradation of the battery by changing the parameters of the system of ordinary differential equations. The degradation of the battery is predicted in terms of change in various parameters of the battery (e.g., capacity, resistance, thermal behavior).
