Abstract: Disclosed is a battery including a casing including cells housed therein and a terminal part including a connection terminal connected to an electrode terminal of a connection apparatus, in which in the casing, a functional groove having a predetermined function in which a longitudinal direction coincides with a connection direction of the connection terminal and the electrode terminal is formed, and the functional groove includes a plurality of functional units having different lengths which are continuously formed. Accordingly, since there is no part that divides a functional unit between a plurality of functional units having different lengths, a size of the functional groove in a direction in which the functional units are continuous is a sum of sizes of a plurality of functional units, and thus it is possible to reduce the size of the battery while securing high functionality.

Abstract: A battery pack (110) comprises a discharge current acquisition component (11), a status acquisition component (12), a similarity calculator (112), and a use application determination component (113). The discharge current acquisition component (11) acquires the current value of a discharge current supplied to a vehicle (30). The status acquisition component (12) acquires the speed of the vehicle (30) operated by the current value acquired by the discharge current acquisition component (11). The similarity calculator (112) compares the current value acquired by the discharge current acquisition component with the speed of the vehicle (30) acquired by the status acquisition component (12), and calculates the similarity between the two. The use application determination component (113) determines whether or not the battery pack is being used for something other than its intended use application, according to the similarity calculated by the similarity calculator (112).

Abstract: In some variations, an apparatus provides real-time monitoring of voltage and differential voltage of both anode and cathode in a battery configured with at least one reference electrode. Voltage monitors are connected to a computer programmed for receiving anode voltage signals; receiving cathode voltage signals; calculating the derivative of the anode voltage with respect to time or with respect to capacity; and calculating the derivative of the cathode voltage with respect to time or with respect to capacity. Other variations provide an apparatus for real-time assessment of capacities of both anode and cathode in a battery, comprising a computer programmed for receiving electrode voltage signals; estimating first and second electrode open-circuit voltages at two different times, and correlating the first and second electrode open-circuit voltages to first and second electrode states of charge, respectively, for each of anode and cathode. The anode and cathode capacities may then be estimated independently.
