Disclosed herein are a methods and system for monitoring battery temperature and providing alerts when temperatures are abnormal, comprising: wirelessly receiving temperature measurement data from a single monobloc or a plurality of monoblocs that are electrically connected in series or parallel, wherein a temperature measurement data represent the temperatures inside each of said plurality of monoblocs; calculating a temperature value, T.sub.PDAVE, equal to an average of the temperature measurement data wirelessly received from all the plurality of monoblocs in a battery; calculating a high temperature difference, T.sub.PDH, as an absolute value of the difference between the highest monobloc temperature in the battery and the T.sub.PDAVE; calculating a low temperature difference, T.sub.PDL, as an absolute value of the difference between the lowest monobloc temperature in the battery and the T.sub.PDAVE; and establishing an alert when the T.sub.PDH is greater than a predetermined high temperature threshold.

Described herein are method and systems for detecting an unauthorized removal of a battery. The system comprising: a battery monitor circuit attached to or embedded in the battery; a remote device, wherein the remote device stores instructions that when executed on the remote device cause the remote device to perform operations comprising: receiving, at the remote device, a wireless signal from the battery monitor circuit comprising voltage and temperature data; evaluating, by the remote device, whether the battery is in its expected location by confirming for each battery, which is expected to be present, whether there has been an unexpected interruption in the wireless signal from the battery; providing an alert notification when there has been an unexpected interruption in the wireless signal.

The disclosure relates to an electrically operated vehicle having an electrical charging cable, by which a vehicle-side accumulator is chargeable by a vehicle-external power supply network in a charging procedure, wherein the charging cable can be unplugged from a vehicle-side terminal at least after completion of the charging procedure, in particular independently and without locking. According to the disclosure, the vehicle and/or the charging cable has a check function, which enables a charging cable usage if a usage authorization is present and blocks the charging cable usage if a usage authorization is not present.

A portable power source for power tools. The portable power source includes a housing defining a battery support and an power outlet, a circuit supported by the housing and including an input terminal on the battery support, an output terminal on the power outlet, and an inverter electrically connected between the input terminal and the output terminal, a battery power source including a battery housing supported on the battery support, at least one battery cell, and a battery terminal connected to the battery cell and electrically connectable to the input terminal, power being transferrable from the battery cell to the circuit to be output through the power outlet, and a frame connected to the housing and extending beyond a periphery of the housing and of the supported battery power source, the frame inhibiting contact with the housing and the battery power source.

A system for battery binding includes a service end electronic device, at least one battery device and at least one carrier device. The service end electronic device is configured to send a carrier identifier corresponding to a carrier device to a battery device for storage therein in order to bind the battery device to the carrier device.

A verification method for battery power supply is to be implemented by a carrier device corresponding to a unique carrier identifier and communicable with a power supply device that stores a reference carrier identifier which corresponds to a carrier device. The verification method is characterized by: by a carrier microcontroller of the carrier device, determining whether or not verification of the power supply device succeeded based on a verification result associated with the unique carrier identifier of the carrier device and the reference carrier identifier stored in the power supply device; and by the carrier microcontroller, controlling the carrier device to utilize electrical energy provided by the power supply device to operate when it is determined that the verification of the power supply device succeeded.

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.

A portable power source for power tools. The portable power source includes a housing defining a battery support and an power outlet, a circuit supported by the housing and including an input terminal on the battery support, an output terminal on the power outlet, and an inverter electrically connected between the input terminal and the output terminal, a battery power source including a battery housing supported on the battery support, at least one battery cell, and a battery terminal connected to the battery cell and electrically connectable to the input terminal, power being transferrable from the battery cell to the circuit to be output through the power outlet, and a frame connected to the housing and extending beyond a periphery of the housing and of the supported battery power source, the frame inhibiting contact with the housing and the battery power source.

An electric movable body transmits a signal including identification information identical to identification information retained in a first power storage pack via near-field communication when the first power storage pack is detached from the electric movable body. A charging device wiredly transmits the identification information received from the electric movable body to a second power storage pack. The second power storage pack transmits via near-field communication a signal including the identification information received from the charging device. The electric movable body collates whether or not the identification information included in the received signal matches the identification information retained in the first power storage pack.

A security device for a battery pack includes a cap, which covers at least a portion of a slide mechanism of a slide battery pack, and a strap. The cap includes a first collar disposed around a first opening and a second collar disposed around a second opening, with the first collar and the second collar aligned along a longitudinal axis of the slide battery pack. The strap matches a contour of the slide battery pack and includes a first projection and a second projection. The strap is positioned along the longitudinal axis of the slide battery pack and the cap is positioned over the strap with the first projection inserted through the first opening and the first collar and the second projection inserted through the second opening and the second collar to secure the cap to the strap and to the slide battery pack.
