摘要： In one aspect, computer-implemented method may include receiving, from one or more sensors associated with a battery pack, one or more measurements pertaining to voltage, temperature, or both. The method may include transforming the one or more measurements into a time-series sequential window format, determining, based on the time-series sequential window format of the one or more measurements, a voltage score and a temperature score, and predicting, based on the voltage score and the temperature score, whether the battery pack is experiencing a fault condition. The prediction is performed by one or more trained machine learning models. Responsive to predicting the battery pack is experiencing the fault condition, the method may include performing one or more preventative actions.

摘要： A battery detection system includes a battery assembly and an electronic device. The battery assembly includes a first connector and a detection module connected to the first connector. The electronic device includes a second connector and a control module connected to the second connector. When the first connector is connected to the second connector, the detection module is configured to output first identification information to the electronic device through the first connector. When the second connector receives the first identification information, the control module confirms that the battery assembly is in a connected state. After the first connector is disconnected from the second connector, the detection module generates and outputs second identification information. When information received by the second connector changes from the first identification information to the second identification information, the control module confirms that the battery assembly is disconnected.

摘要： For each cell in a plurality of cells from a same manufacturing run, a first and a second cell characteristic are received in order to obtain a plurality of cell characteristics. For each cell, a batch compatibility number that is associated with a number of compatible cells that that cell is compatible with is determined based at least in part on the plurality of cell characteristics. The plurality of cells is sorted according to the batch compatibility numbers to obtain a sorted list of cells. A plurality of compatible cells to include in a battery is selected from the plurality of cells, including by evaluating the plurality of cells according to the order of the sorted list of cells and beginning with the lowest batch compatibility number.

摘要： Presented are passive temperature control systems for thermal management of electrical components, methods for making/using such thermal management systems, and aircraft equipped with smart-material activated temperature control systems for passive cooling of battery modules. A thermal management system is presented for passively cooling an electrical component stored inside a module housing. The thermal management system includes a cooling chamber that movably attaches adjacent a module housing that contains an electrical component, such as a rechargeable battery module. The cooling chamber contains a sublimable cooling agent, such as dry ice. A biasing member biases the cooling chamber away from the module housing. A smart material actuator is attached to and interposed between the cooling chamber and module housing. The smart material actuator extracts thermal energy from the module housing and, once heated to a phase transformation temperature, contracts and thereby pulls the cooling chamber into contact with the module housing.

摘要： The technology relates to a capacity indicator for use with a battery. One aspect of the technology provides an improved activation circuit for a capacity indicator that is easier to use and less prone to false alarms. A further aspect of the technology provides an improved indicator which is able to indicate battery capacity without requiring the use of expensive battery labels such as thermochromic strip. A further aspect of the technology provides a capacity determination circuit which is housed within a battery and which is able to provide a more accurate indication of battery capacity.

摘要： Provided is a system and medical device that includes self diagnosing control switches. The control switch may be slidable within a slot in order to control activation of some function of the medical device. Due to natural wear and tear of movement of a control switch, the distances along the sliding slot that correspond to how much energy is used for the function may need to be adjusted over time in order to reflect the changing physical attributes of the actuator mechanism. The self diagnosing control switches of the present disclosures may be configured to automatically adjust for these thresholds using, for example, Hall effect sensors and magnets. In addition, in some cases, the self diagnosing control switches may be capable of indicating external influences on the controls, as well as predict a time until replacement is needed.
