摘要:
A method for managing a battery module includes receiving data relating to one or more operational parameters of the battery module. The method also includes determining whether a first operational parameter of the one or more operational parameters violates a first threshold. Additionally, the method includes transitioning the battery module from an operational mode to a sleep mode in response to a determination that the first operational parameter violates the first threshold.

A battery tester, includes a voltage controlled display. The battery tester is disposed on a battery with a first voltage divider having a terminal coupled to a terminal of the voltage controlled display and a second voltage divider having a terminal coupled to a second terminal of the voltage controlled display. The second voltage divider includes a nonlinear device. A major advantage of the tester compared to other testers is that a consumer can merely look at the tester on the battery to determine whether the battery is good or not. This tester eliminates the need to hold the battery and depress a switch to engage the battery tester.

A battery strength tester (10) used on a battery (18) which has indicating means (17) to indicate the strength of the battery and switching means (24) which can easily be employed to complete a circuit so as to place the indicator means across the terminals of the battery and display the charge of the battery and wherein said switch (24), after a predetermined interval or temperature is reached, automatically opens to break the electrical contact across the battery terminals (20). A light emitting material employed as the indicator material is another special feature of the battery strength tester.

A status tester for an electrochemical cell (1), comprising an (1) elecrically resistive element (18), switchably contactible with the (18) terminals of the cell, and visual heat responsive means (24) thermally connected with the resistive means such that, on passage of electric current through the resistive element, heat generated thereby excites the heat responsive means, has at least two switches (65a, 65b) for one (65a, 65b) terminal, each switch being associated with an overall different electrical resistivity of the resistive element, thereby to allow testing for suitability for high and low drainage devices. Incorporation of a variable resistivity element, where resistance changes with ambient temperature, allows the tester to provide consistent results over a range of ambient temperatures.

The combination of an electrochemical cell having two external termini, a label and a covered cell condition indicator;
said cell comprising: a sealed cylindrical container an outer surface whereof provides one of said termini; a cover sealing said container; a further one of said external termini; and means for conducting electricity from the inner side of said container to said further terminus; said indicator being disposed externally of said sealed container and comprising a resistance heating element and a thermochromic display and said resistance heating element having two electrical contacts which in the operation of said indicator are electrically conducted to respective said termini, characterised in that a contact is disposed to contact one of said termini and the other contact is disposed at the other one of said external termini of said sealed cylindrical container, the first of said contacts being separated from electrical contact with a first of said termini by an apertured insulator on the side of said cell whereby in operation of said indicator said first contact may be brought into electrical contact with said first terminus by application of external pressure to cause it to pass through an aperture in said insulator and come into electrical contact with said first terminus, and whereby said electrical contact is broken by removal of said external pressure, and in that said indicator is positioned between the external surface of said label and one of said first termini; and further characterised in that said thermal insulator is the minimum thickness necessary to permit the cell condition indicator to function reliably, said thermal insulation being positioned between said resistance heating element and the external surface of said cylindrical container.
