Problems solved by technology

Of course, computer-based overall vehicle analysis systems for analytical purposes are available and effective, but such systems are usually specific to one specific model of vehicle and are therefore only applicable to an extremely narrow range of vehicles, and in any case are not suitable for roadside use
[0004] Another question arises from the fact that many failures are episodic and generally untraceable using existing legacy equipment before it becomes severe enough to persist
[0005] Furthermore, such methods and devices must be ready to be used by inspectors providing roadside assistance in severe weather conditions, and with respect to the state of maintenance of the vehicles inspected under similar severe conditions, the fact that Many modern vehicles are built to be very resistant to rain and snow, as well as oil and other fluids, so it is relatively difficult to gain access to certain parts of the car, at least the running system, especially the starting system and related electrical components.

Embodiment Construction

[0028] In the embodiment of Figure 2 (and the corresponding figure 1 prior art), in figure 1 In the representative prior art shown, a battery 100 is connected to a load 104 via a switching circuit 102 forming part of an overall detection arrangement 106 and the heat generated therefrom is absorbed by a heat sink 108 accordingly.

[0029] Circuitry 110 provides a voltage curve analysis which refers to known voltage data curves established in a corresponding database to determine the battery type.

[0030] In the embodiment of FIG. 2 , handset 120 is connected to battery 124 via closed loop current control circuit 122 such that switching circuit 128 applies transient load 126 to generate the battery's normal operating current (approximate value), which is displayed at 130 .

[0031]The switching circuit turns on the load 126 (typically) for about 20 milliseconds, and the circuit 122 is set to draw current from the battery 124 on the order of 100 amps. The generated voltage cur...

Abstract

The invention relates to a method and apparatus for automotive and other battery testing. Particularly, but not exclusively, the invention relates to such method and apparatus applicable to the roadside testing of automotive vehicles' batteries, and the corresponding testing of such vehicles' batteries in diagnostic and service-oriented functions.

Description

Technical field: [0001] The invention relates to a method and a device for testing motor vehicle batteries and other batteries. In particular, but not limited to, the present invention relates to methods and apparatus which can be used for roadside testing of motor vehicle batteries, as well as for diagnostic testing and functional testing of such motor vehicle batteries for maintenance purposes here. A particular practical use of embodiments of the present invention is to provide methods and apparatus that are particularly useful to patrol officers providing roadside assistance to motorists. [0002] The invention will also find use in non-motor vehicle applications. Background technique: [0003] A specific practical problem in the fault diagnosis of motor vehicles consists in providing simple and practical means capable of quickly pointing out common faults in basic operating systems. Of course, computer-based overall vehicle analysis systems for analytical purposes ar...
