A pluggable state-of-charge (SOC) indicator and methods of use are disclosed. The pluggable SOC indicator includes at least one voltage input jack for connecting to a battery, at least one instance of control electronics, and at least one SOC indicator, such as a 5-bar liquid crystal display (LCD). Embodiments of the pluggable SOC indicator include, but are not limited to, a pluggable single-connector SOC indicator, a pluggable dual-connector SOC indicator, and a pluggable quad-connector SOC indicator.

A battery indicator system for a vehicle. In one embodiment, the battery indicator system includes a power port for the vehicle, the power port having a socket and battery monitor in electrical communication with a power source on a vehicle. The battery monitor is operable in a status mode in which it indicates or communicates to an indicator at least one of the state of charge and the state of health of the power source on the vehicle while a device is being charged or powered via the power port. The power port can include an integrated indicator, such as one or more lighting elements. The power source can provide power to the device to charge and/or power the device and provides power to the battery monitor so that a viewer of the port can easily monitor the status of the charge of the power source itself (versus the charging status of the device) via the power port to ensure the power source is not inadvertently drained. In one embodiment, the battery monitor can be mounted to the power source separate from the power port, and communicate at least one of the state of charge and state of health information for display on an indicator.

The battery monitoring chips each include a battery monitoring function section that is provided so as to correspond to a respective battery cell group and to monitor a state of each battery cell contained in the corresponding battery cell group, and a regulator that generates a drive voltage to supply to a configuration circuit of the battery monitoring function section based on power supplied from the battery. The battery monitoring chips are connected together in series to give a communication path, with an input end of the regulator electrically connected to an output end of another regulator. A microcomputer is connected to a battery monitoring chip, and is driven by a drive voltage generated by the regulator of the battery monitoring chip accompanying power consumption by each of the battery cells.

Provided are an information processing device, an information processing system, an information processing method, and a computer program capable of visually and easily grasping a state of an energy storage device. An information processing device includes: an acquisition unit configured to acquire information including a state of an energy storage device by communication at predetermined time intervals; a storage processing unit configured to store the acquired information in a storage medium in association with information for identifying the energy storage device; a transmission processing unit configured to transmit screen information of a state screen including an image of a system including the energy storage device and a graphic indicating the state of the energy storage device to a communication terminal device; and an automatic monitor unit configured to update information of the graphic based on latest information stored in the storage medium and periodically transmit the information of the graphic to the communication terminal device.

A method for indicating a state of a battery of a vehicle when the vehicle has suffered an accident, in which acoustic signals, which include coded items of information about at least one operating parameter of the battery, are sent by a loudspeaker of the vehicle. The acoustic signals are received by a microphone of a terminal and the coded items of information are decoded and output by the terminal.

In various implementations, a housing for a battery tester may include a body with a first side and an opposing second side. The first side may include a presentation member, such as a screen and an input member. The screen may include a touch screen and/or the input member may include a keypad, such as a keypad with arrows. The second side may be magnetic such that the battery tester can be coupled to a magnetic surface. The second side may, in some implementations, include holster(s) that allows clamps to be stored in the holster. The holster(s) may be removable.

An indicator device for a rechargeable battery pack, in particular, a rechargeable battery pack of a power tool, for indicating a charge state of the rechargeable battery pack, including at least one charge state indicator unit, which includes at least one indicator element for indicating the charge state of the rechargeable battery pack, and including at least one control line for transmitting at least one electrical and/or electronic signal, in particular, as a function of a charge state of the rechargeable battery pack, from a separate control unit of the rechargeable battery pack, in particular, structurally separated with respect to the charge state indicator unit, in particular, from main control electronics of the rechargeable battery pack to the charge state indicator unit. The charge state indicator unit is configured to short-circuit at least one indicator element as a function of the electrical and/or electronic signals transmitted via the control line.

A method for displaying a battery level, an electronic device, and a non-transitory computer-readable storage medium are provided. The method includes operations as follows. Obtaining an estimated increment of the power of an electronic device based on a charging current of the electronic device; and the battery indicator of the electronic device is updated based on the estimated increment of the battery level of the electronic device, where the battery indicator is configured to display the battery level and presented in percentage.

A module battery system is disclosed and, more specifically, a module battery system which can select and output a desired capacity through a combination of a plurality of battery modules and notify the outside of an abnormal situation through a self-diagnosis and performs a self-protection operation as necessary at the same time.

A system and method is disclosed for detecting remaining battery voltage or capacity in an infusion device and generating alarms based on the detection. The battery lifetime extension method includes providing an infusion device that derives its power from a rechargeable battery. The infusion device may derive its power from a rechargeable battery. Furthermore, the infusion device receives, at predetermined intervals of time in real-time sensor data comprising: a voltage, a change in the voltage over the predetermined interval of time, an average current, a temperature, and a remaining voltage or capacity reported by a battery gas gauge integrated circuit (“IC”) associated with the rechargeable battery. An improved and customized neural network model utilizes the sensor data to determine an indicia of the actual remaining voltage or capacity of the rechargeable battery in real-time. The indicia may be used to lengthen and/or abate ongoing medical infusion therapy.
