A busbar for a battery system according to an exemplary embodiment of the present invention includes: a first bar member and a second bar member which are spaced apart from each other; and a third bar member which connects the first bar member and the second bar member to define a common bar, in which the third bar member is shunt resistance having ohmic resistance and electrically connects the first bar member and the second bar member. In addition, a battery system according to the exemplary embodiment of the present invention includes the busbar.

A sensor arrangement for a network of busbar links of a battery module is provided, the sensor arrangement comprising: an array of sensors, each sensor having an output arranged to provide an indication of current in a respective busbar link of the network; a processor coupled to the outputs of the sensors and configured to: receive data from the sensor outputs; process the data to determine a current in each of a set of busbar links that are connected at a node of the network; and compare the currents in the busbar links of the set to determine an overall current at the node.

A method for measuring a battery reserve capacity of a storage battery is applied to a battery detection device which is electrically connected to the storage battery by a Kelvin connector. The method includes: sending an input signal to a storage battery to control the discharging of the storage battery, and acquiring an output signal which is fed back, within an input duration of the input signal, by the storage battery regarding the input signal; determining a target battery parameter according to the output signal; acquiring a battery capacity table, wherein the battery capacity table includes a correlation between a battery parameter and a battery reserve capacity; and according to the battery capacity table and the target battery parameter, determining a battery reserve capacity corresponding to the target battery parameter. The measurement time for a battery reserve capacity of a storage battery is reduced, and the measurement efficiency is improved.

A battery sensor for detecting a current flowing through an electrical conductor, wherein the battery sensor has at least two mutually independent measuring devices for detecting the current flowing through the electrical conductor. The measuring devices are structurally and/or electrically completely isolated from one another.

A battery management system includes a monitoring device and a controller. The monitoring device is arranged in a housing accommodating a battery, monitors the battery and acquires battery monitoring information that includes information indicating a state of the battery. The controller performs wireless communication with the monitoring device and execute a predetermined process based on the battery monitoring information. The controller transmits a request for battery monitoring information to the monitoring device. The monitoring device transmits the battery monitoring information to the controller in response to the request. The controller determines whether missing of the battery monitoring information has occurred based on a correlation between the battery monitoring information acquired from the monitoring device via wireless communication and relationship information held by the controller related to the battery monitoring information.
