Discussed is an application that efficiently utilizes a vehicle battery by predicting performance of the vehicle battery and an available driving distance based on environmental condition of an area where a vehicle is parked and state information of the vehicle battery.

An electric marine propulsion system is configured to propel a marine vessel and comprises a lithium ion (LI) battery, a marine drive having an electric motor powered by the LI battery, and a user input device configured to receive a user input selected an emergency depletion mode. The system further includes a controller configured to determine a battery charge level for the LI battery and reserve a minimum charge level of the LI battery associated with a normal operating area for the LI battery by ceasing power delivery from the LI battery to the marine drive once the battery charge level reaches the minimum charge level. In response to selection of the emergency depletion mode, power is delivered from the LI battery to the marine drive when the battery charge level is below the minimum charge level.

An implantable medical device (IMD), includes a processor for controlling the IMD; circuitry for providing therapeutic or diagnostic medical operations for a patient; wireless communication circuitry for conducting wireless communications; a non-rechargeable battery; and device power control circuitry. The device power control circuitry includes at least one capacitor; charging control circuitry for switching between charging the at least one capacitor using the non-rechargeable battery and discharging the at least one capacitor to provide power for device operations. The IMD is configured to maintain a count related to a number of times of discharge of the at least one capacitor to provide an end-of-life estimation for the non-rechargeable battery.

The method may include: feeding the battery to a test station; bringing it to a test temperature; stabilizing the temperature within less than 2 K; measuring a load cycles using a high-precision coulometry apparatus; carrying out measurement until fulfilment of a termination criterion; ascertaining a first and a second value for a discharging capacity using two different calculation rules, wherein calibration is handled differently in the two calculation rules; carrying out an optimization process; determining a residual value of the battery; and determining whether the used battery is to be employed for use in a static energy storage device.

The battery residual value display device includes: a battery information receiving module; an attenuation function determining module; a second residual value determining module; a graph output module configured to output a graph of which one axis indicates residual values of a battery and another axis indicates information on an elapsed time from a time of manufacture of the battery; and a display unit. The graph output module is configured to output: in the graph, a display indicating a first residual value; a display indicating boundaries between a plurality of residual value ranks obtained by dividing the residual values in accordance with a level of a second residual value; and a display indicating boundaries between a plurality of groups, indicating types of applications in which the battery can be used, obtained by dividing the plurality of residual value ranks in accordance with the level of the second residual value.

Based on changes in a battery (e.g., age, temperature) of an electronic device, battery power prediction and correction logic of the electronic device may correct a power capability and/or regulate power associated with the battery. For example, the battery power prediction and correction logic may operate the battery to supply up to a maximum of a power capability with an applied correction factor based on a voltage measurement and a cutoff voltage associated with the battery.

A vehicle electrical system includes a battery, a customer connection point, a switch electrically connected in series between the battery and the customer connection point, a computer communicatively coupled to the switch, and a transceiver communicatively coupled to the computer. The computer is programmed to instruct the switch to open in response to a state of charge of the battery decreasing below a charge threshold, receive an input selecting a time limit, and instruct the transceiver to transmit a message to a remote server upon determining that the state of charge of the battery will decrease below the charge threshold in less than the time limit from a current time.

A refuse vehicle including a chassis, a body assembly coupled to the chassis, the body assembly defining a refuse compartment, an electric energy system configured to store power and supply power to the refuse vehicle, and a power control system configured to measure one or more electrical attributes of the refuse vehicle and determine a power profile for the refuse vehicle, the power profile describing a length of time the refuse vehicle can continue to operate based on a remaining power of the electrical energy system, and wherein the power control system controls operation of a lift assembly of the refuse vehicle based on the power profile.

The radiography apparatus is driven by power supplied from the battery. In the radiography apparatus, a radiation source that emits radiation to a subject, a radiation detector that receives the radiation transmitted through the subject and outputs a radiographic image, and an image processing device that performs image processing on the radiographic image are integrated. A CPU of the image processing device acquires a remaining level of the battery. The CPU performs control to operate both a first processing block that performs a noise suppression process and a visibility improvement process as first image processing and a second processing block that performs a density correction process as second image processing in a case in which the remaining level of the battery is equal to or greater than a threshold value. In contrast, in a case in which the remaining level of the battery is less than the threshold value, the CPU performs control to stop an operation of the first processing block and to operate only the second processing block.
