A method of controlling the charge current during charging of a lithium-ion battery. A battery charging controller is based on a Kalman filter, which uses estimated battery states to generate a feedback metric to continually adjust a battery cell model. The battery cell model then delivers data to an optimization process that generates the charge current.

A degradation-determination system includes a volume change detecting unit configured to detect a volume change of a lithium-ion battery, a capacity change detecting unit configured to detect a capacity change of the lithium-ion battery, and a charge control unit configured to control charge of the lithium-ion battery. The charge control unit is configured to determine that the lithium-ion battery is in a state of degradation, upon occurrence of a condition in which volume expansion of the lithium-ion battery is detected by the volume change detecting unit, in conjunction with a condition in which a decrease in a capacity of the lithium-ion battery is not detected by the capacity change detecting unit.

This application embodiment provides a method for equalizing the battery module, an apparatus, a battery module and a power management controller, including: judging whether the first battery core and the second battery core enter their respective fully-charged interval; if the first battery core enters and the second battery core doesn't enter, discharging the first battery core until the second battery core enters; if the first battery core doesn't enter and the second battery core enters, judging whether the maximum value of the first charging voltage of each battery cell in the first battery core is greater than a third preset value; if so, discharging the second battery core until the first battery core enters; if not, controlling both to rest a preset time; after resting for the preset time, discharging the first battery core and the second battery core until the SOC of each battery cell enters a same state.

A rechargeable battery jump starting device with a control switch backlight system. The control switch backlight system is configured to assist a user viewing the selectable positions of the control switch for selecting a particular 12V or 24V operating mode of the portable rechargeable battery jump starting device in day light, sunshine, low light, and darkness.

The present invention relates to a service platform implemented by one or more computers. The platform comprises one or more micro-services, each micro-service having a standardized generic structure comprising: a subservice implementing a business function, a messaging sub-service. The platform also includes a communication system for exchanging data and messages, referred to as unified communication system.

The present invention detects a predictive abnormal phenomenon in a battery pack and prevents the use of the battery pack before power is shut off at a fuse. The battery pack comprises: a battery cell; a connection unit which is electrically connected to the battery cell and is connected to an external electrical apparatus main body; and a control unit which controls the battery cell, wherein, when detecting an abnormal state such as chattering, the control unit causes a charge prevention signal (LS) and a discharge prevention signal (LD) to be continuously output and makes the charge and discharge of the battery pack impossible (steps 226-228). The continuous output of these prevention signals is configured not to be negated by an operation of a user, and the battery pack can be made unusable by software control.

The present disclosure relates to systems, devices, and methods for analyzing health of vehicle batteries. Vehicle batteries tend to degrade over time. The described systems, devices, and methods quantify this degradation (or quantify remaining health of the battery) by comparing average energy used to charge or discharge the battery by a charge level unit to a nominal quantity of energy used to charge or discharge a battery in optimal health by a charge level unit. Charge data for previous charge events of the vehicle battery can be used in the calculation, and can be filtered by identifying qualified charge events based on at least one of a number of metrics. Usage data for previous usage events of the vehicle battery can be used in the calculation, and can be filtered by identifying qualified usage events or subgroups of usage event based on at least one of a number of metrics.
