A method including: receiving identification information of a charging device including individual identification information of the charging device, and identification information of a power storage device, which is connected to the charging device, including individual identification information of the power storage device, from at least one of the charging device and the power storage device; determining the possibility of charging the power storage device from the identification information of the power storage device and the identification information of the charging device received; and transmitting information indicating the determined possibility of charging the power storage device to at least one of the charging device and the power storage device.

The self-powered device includes a control circuit supplied by a power supply source, and self-destruction unit configured to destroy the device by impairing the power supply source. The invention also relates to the corresponding self-destruction method.

Provided is a secondary battery cell capable of reliably preventing an integrated circuit provided to the secondary battery cell from being removed from the secondary battery cell. A secondary battery cell (20) includes an integrated circuit (IC chip) (50) that stores identification information (for example, identification number (ID number) given to the integrated circuit itself). The integrated circuit (50) includes a wiring abnormality detection circuit. When the integrated circuit (50) is removed from the secondary battery cell (20), the wiring abnormality detection circuit detects a wiring abnormality.

A battery system is provided, the battery system comprising a battery cell pack and a sensor unit comprising a charge detection sensor arranged to detect a level of charge of the battery cell pack and at least one further sensor. The battery system further comprises a cell protection unit (114) arranged between the battery cell pack and a terminal of the battery system. The battery system further comprises a kill switch circuit comprising a load and a switch arranged in series over the battery cell pack. The switch is configured initially to be in an open state and, once closed, to remain in a closed state. The battery system further comprises a controller configured to receive measurements from the sensor unit. The controller is further configured to detect, using measurements from said charge detection sensor, the level of charge being below a predetermined threshold. Upon detection of the level of charge being below a predetermined threshold, the controller is configured to disconnect the terminal from the battery cell pack using the cell protection unit. The controller is further configured to detect, using measurements from the at least one further sensor, an unauthorized displacement of the battery cell pack outside of an allowed range. Upon detection of the unauthorized displacement of the battery cell pack, the controller is configured to close the switch of the kill switch circuit to disengage the battery cell pack to a permanently depleted state.

The invention provides an anti-theft system for lithium batteries in golf carts, comprising an integrated hardware module that selectively enables or disables power output from the battery. A mobile application on a user device communicates with the anti-theft hardware through secure encrypted protocols. When activated, the system interrupts the power path between battery cells and output terminals, rendering the battery inoperable during unauthorized use attempts. The system incorporates tamper detection sensors that monitor physical interference and automatically alert users via the mobile application. Authentication mechanisms include biometric verification, passwords, and personal identification numbers to ensure only authorized users can control the functionality. Additional features include geographic boundary detection that automatically activates protection when the user device moves beyond a predetermined distance from the battery, real-time status monitoring, and comprehensive event logging for security auditing. The system provides effective protection against theft while maintaining user convenience.

A theft deterrent device configured to facilitate remote disconnection of a power supply from a powertrain of one or more vehicles may be coupled to an ignition circuit of a vehicle and may comprise a transceiver configured to send and receive data. Vehicle(s) may be grouped by myriad criteria data (which a user may define in an associated smartphone application) and may be remotely enabled/disabled based on each vehicles' association with the criteria data (membership in the group defined by criteria data). For example, based on a vehicles attribute data (e.g., lot number, VIN number, geolocation), the techniques herein may be configured to remotely enable/disable the vehicle by engaging a switch to close/interrupt an ignition circuit of the vehicle.
