A battery system with a large-format Li-ion battery powers attached equipment by discharging battery cells distributed among a plurality of battery packs. The discharging of the battery cells is controlled in an efficient manner while preserving the expected life of the Li-ion battery cells. Each battery pack internally supports a battery management system and may have identical components, thus supporting an architecture that easily scales to higher power/energy. Battery packs may be added or removed without intervention with a user, where one of battery packs serves as a master battery pack and the remaining battery packs serve as slave battery packs. When the master battery pack is removed, one of the slave battery packs becomes the master battery pack. Charging and discharging of the battery cells is coordinated by the master battery pack with the slave battery packs over a communication channel such as a controller area network (CAN) bus.

The present invention is a message updating system for an electronic label. The system comprises a message updating device, wherein a controller thereof controls a power-supply transmission unit and a message-update transmission unit to respectively transmit a charging signal and a message-updating to the electronic label for charging the electronic label and updating label information of the electronic label. A detection device picks up the label information to generate label content information, transmits the label content information to the controller to make the controller compare the label content information with update comparison information, and generates an alert message if the label content information is different from the update comparison information. The present can charge the electronic label that is mounted on an article and update label information simultaneously while the article is being transported.

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.
