Abstract: The present document describes techniques associated with a blind battery connector. The blind battery connector described herein enables a user to blindly engage, safely and securely, a battery connector with a system-side connector. In aspects, the blind battery connector includes polarity-oriented magnets at both the battery connector and the system-side connector to automatically align and engage the battery connector with the system-side connector with correct orientation. The magnets may be embedded or removably assembled to the battery connector and the system-side connector. The blind battery connector controls initial alignment of the battery connector for coupling with the system-side connector and provides additional mechanical strength to the coupling against drop, vibration, and shock. The techniques described herein may decrease battery connection time at factory assembly, increase units per hour, and lower operating costs, while decreasing the likelihood of battery connector damage and/or reverse polarity engagement.

Abstract: A battery pack includes a battery, a first temperature sensor configured to provide a first temperature value associated with a temperature of the battery, a heat source disposed proximate to the battery and configured to heat the battery, a second temperature sensor configured to provide a second temperature value associated with a temperature of the heat source, and a control board coupled to the first temperature sensor and the second temperature sensor, wherein the control board is configured to receive the first temperature value and the second temperature value. The control board is configured to compare the first temperature value and the second temperature value to determine a temperature gradient between the battery and the heat source and transmit an alert if the temperature gradient exceeds a first temperature gradient threshold.

Abstract: An indexed sequence of bits in a buffer is allocated for tracking a battery charging state. The indexed sequence of bits has a first number of bits. A battery voltage of a rechargeable battery is sampled at a sampling rate. For each sampled battery voltage, the battery voltage is compared with a voltage threshold. A next bit position in the indexed sequence of bits is identified. In accordance with a determination that a comparison result is true, a predefined first value is added to the next bit position. A second number of bits that are filled with the predefined first value is determined. A ratio between the second number and the first number is also determined. In accordance with a determination that the ratio exceeds a threshold step-down ratio, a battery charge voltage is stepped down. The rechargeable battery is charged to a step-down voltage.

Abstract: A battery provisioning method is implemented by an outdoor electronic device having a rechargeable battery. The electronic device obtains geolocation information of a geographic location where the electronic device is located. The electronic device further obtains outdoor temperature information of the geographic location based on the geolocation information. A battery setting of the rechargeable battery is determined based on the outdoor temperature information, and used to provision the rechargeable battery of this electronic device. In some implementations, the rechargeable battery is provisioned with an upper limit for a state of charge at each time of installing and initializing the electronic device. During normal operation, the rechargeable battery of the electronic device is charged up to the upper limit for the state of charge, while the upper limit for the state of charge of the rechargeable battery may be updated periodically or upon request.

Abstract: A method for monitoring battery degradation including receiving, from a pressure sensor, a first pressure value associated with a battery pack, comparing the first pressure reading to a first pressure threshold value and if the first pressure reading is greater than the first pressure threshold value, applying a first battery discharge pulse to the battery pack. The method further includes calculating a first internal resistance value of the battery pack in response to the first battery discharge pulse, comparing the first internal resistance value to an initial internal resistance value, and transmitting an alert to an electronic device if the first internal resistance value exceeds the initial internal resistance value.

Abstract: This application is directed to a battery protection system including a sense resistor, a comparator, a switching component, and a protection integrated circuit (PIC). The sense resistor is electrically coupled in series with one of a plurality of rechargeable battery cells that are coupled in parallel in a battery. The comparator is coupled to the sense resistor and configured to compare a voltage drop across the sense resistor with a reference voltage to determine whether a subset of the rechargeable battery cells is not charging in the battery. The switching component is coupled to the battery, while the PIC is coupled to the comparator and the switching component. The PIC is configured to control charging and discharging of the battery including disabling the battery from being charged in accordance with a determination that a subset of the rechargeable battery cells is not charging in the battery.

Abstract: The present document describes systems and techniques for battery management and optimization using voice integration systems. These techniques include one or more electronic devices defining a voice integration system and having connectivity to a server system. These devices are configured to provide audio data relating to battery operations, including battery charging, to a user of an electronic device. Further, these techniques enable the user of the electronic device to provide additional audio data to the voice integration system and, thereby, instruct the server system to perform one or more actions relating to battery operations associated with the electronic device. In this way, the user can manage and optimize battery operations using the voice integration system.

Abstract: The present document describes techniques associated with right-to-repair battery-replacement methodologies and applications thereof. These techniques include detecting a replacement battery in an electronic device (a new battery or the same battery reinstalled), authenticating the replacement battery, and monitoring battery characterization and health of the replacement battery. Using these techniques fulfills sustainability and right-to-repair options, aligning with customer rights and government regulations. Further, these techniques enable replacement of an embedded battery in a user's device and detection that the replacement battery was installed and is safe for use by the device. A battery health monitor may be implemented on the device to monitor the health of the replacement battery. In some aspects, the battery health monitor may be a subscription-based service implemented via an application executed on the device or via a system-level application.
