Certain example embodiments relate to battery management systems and/or methods, and for example to a method and/or an electronic device for an on-device real-time customization of charge profiles for a battery in the electronic device.
The existing methods and systems provide a static implementation of charge profiles of a battery.

Further, battery temperature and usage behaviour (behavior) have a huge impact on battery charging and still they are not taken into account. In different operating conditions, fixed charge profiles must not be presumed to meet the controlled environment results. Also, the existing methods and systems do not cater well in different operating/usage conditions (e.g., temperature throttling of the battery, user involvement of the battery, or the like) so as to results in reducing the user experience.
Further, the existing methods and systems attempt to generate an adaptive charge profile for the battery, but the existing methods and systems requires extra circuitry/hardware elements and look-up data information.

The processor (110) is coupled with the communicator (120), the memory (130), the charge profile customization controller (140), the machine learning model controller (150) and the battery (160).
The charge profile customization controller (140) determines one or more charging behavior parameter(s) of the battery (160) during every charging cycle. The one or more charging behavior parameter(s) can be, for example, but not limited to a charging duration for which the battery (160) is charged, a cable plugin time, a number of times the cable is plugged in, a charging rate, a charging instance of day, and a cable plug out time.
Further, the charge profile customization controller (140) determines one or more discharging behavior parameter(s) of the battery (160) subsequent to every charging cycle. The one or more discharging behavior parameter(s) can be, for example, but not limited to an amount of the battery (160) consumed by each application of the electronic device (100), a duration of battery consumption of each application of the electronic device (100), a calendar input, a discharge rate of the battery (160), and a discharging instance of day for significantly different discharge rate. The application can be, for example, but not limited to a game application, a chat application, a social media application, a map application or the like.
Based on the one or more charging behavior parameter(s) and the one or more discharging behavior parameter(s), the charge profile customization controller (140) generates a charging profile for charging the battery (160). The charging profile is generated by applying one or more machine learning (ML) model(s) on the one or more charging behavior parameter(s), and the one or discharging behavior parameter(s) of the battery (160) using the machine learning model controller (150). Further, the charge profile customization controller (140) charges the battery (160) using the generated charging profile for subsequent charging-discharging cycles.
The charge profile is customized for a particular user after analysing user's charge and discharge behavior. The charge profile is customized in terms of charge time, charge trajectory and degradation. The charge profile can be, for example, but not limited to a retro charging profile, an optimistic charging profile, an aggressive charging profile, and a balanced charging profile.
The retro charging profile is used by a user who plug in the charger cable all the time. The retro charging profile may be used in overnight charging, during long work hours, while travelling in cars etc. The optimistic charging profile is used by the user who want more life from the battery (160) with minimal or small increase in charge time. The aggressive charging profile provides a quick charging before meeting or quick boost when the battery (160) is fully drained or sudden travel plan without charge connection availability etc. The aggressive charging profile provides the quick charging at electrical vehicle (EV) station for an EV. The balanced charging profile is used by a user who need initial quick burst and still want to maintain decent battery life.
In another embodiment, the charge profile customization controller (140) measures an amount of time for which the battery (160) is charged, during every charging cycle and monitors a discharge pattern due to usage of the electronic device (100), subsequent to every charging cycle. The charge profile customization controller (140) applies the charging profile in response to the measured time and discharge pattern such that battery operation is optimized (e.g. minimum degradation, temperature control, charging time etc.).
Further, the charge profile customization controller (140) generates the AI model including a correlation of the time, discharge pattern and the charging profile that minimizes or reduces the rate of discharge of the battery (160). The AI model selects the charging profile in response to time and discharge pattern of the battery (160). The current battery characteristics (e.g. temperature of the battery) is also fed as an input to the AI model.
Further, the charge profile customization controller (140) determines usage characteristics of the electronic device (100) and modifies the generated charging profile based on the usage characteristics of the electronic device (100). The usage characteristics can be, for example, but not limited to a user type, a current location of the electronic device (100), calendar events, current health characteristics of the battery (160), and current context of the user. The user type can be, for example, but not limited to an aggressive user having full fast charging requirement, an aggressive user having partial fast charging requirement, a passive user having fast charging with better life requirement, a passive user having balanced charging requirement, and a passive user having life squeezer charging requirement.

By using the modified charging profile, the charge profile customization controller (140) charges the battery (160).
The charge profile customization controller (140) is physically implemented by analog and/or digital circuits such as logic gates, integrated circuits, microprocessors, microcontrollers, memory circuits, passive electronic components, active electronic components, optical components, hardwired circuits and the like, and may optionally be driven by firmware.
Further, the processor (110) is configured to execute instructions stored in the memory (130) and to perform various processes. The communicator (120), comprising communication circuitry, is configured for communicating internally between internal hardware components and with external devices via one or more networks. The memory (130) also stores instructions to be executed by the processor (110). The memory (130) may include non-volatile storage elements. Examples of such non-volatile storage elements may include magnetic hard discs, optical discs, floppy discs, flash memories, or forms of electrically programmable memories (EPROM) or electrically erasable and programmable (EEPROM) memories. In addition, the memory (130) may, in some examples, be considered a non-transitory storage medium. The term “non-transitory” may indicate that the storage medium is not embodied in a carrier wave or a propagated signal. However, the term “non-transitory” should not be interpreted that the memory (130) is non-movable. In certain examples, a non-transitory storage medium may store data that can, over time, change (e.g., in Random Access Memory (RAM) or cache).
Further, at least one of the pluralities of modules/controller may be implemented through the AI model using the machine learning model controller (150). The data driven controller can be a ML model based controller and AI model based controller. A function associated with the AI model may be performed through the non-volatile memory, the volatile memory, and the processor (110). The processor (110) may include one or a plurality of processors.

The one or a plurality of processors control the processing of the input data in accordance with a predefined operating rule or AI model stored in the non-volatile memory and the volatile memory. The predefined operating rule or artificial intelligence model is provided through training or learning.
Here, being provided through learning indicates that a predefined operating rule or AI model of a desired characteristic is made by applying a learning algorithm to a plurality of learning data. The learning may be performed in a device itself in which AI according to an embodiment is performed, and/o may be implemented through a separate server/system.
The AI model may comprise of a plurality of neural network layers.
