fig. 1 is a schematic structural diagram illustrating a start signal simulation apparatus used in a test process of an intelligent battery sensor according to an exemplary embodiment of the present invention.
Detailed Description
The start signal simulation apparatus for an intelligent battery sensor and the test system and method thereof according to the present invention will be described below by way of embodiments with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention to those skilled in the art. It will be apparent, however, to one skilled in the art that the present invention may be practiced without some of these specific details. Rather, it is contemplated that the invention may be practiced with any combination of the following features and elements, whether or not they relate to different embodiments. Thus, the following aspects, features, embodiments and advantages are merely illustrative and should not be considered elements or limitations of the claims except where explicitly recited in a claim(s).
Fig. 1 is a schematic structural diagram illustrating a start signal simulation apparatus used in a test process of an intelligent battery sensor according to an exemplary embodiment of the present invention. As shown in fig. 1, the start signal simulation apparatus according to the exemplary embodiment includes a signal generator (may also be referred to as a "waveform generator") for simulating an electric signal output from a vehicle battery at the time of engine start. Compared with a high-power supply adopted in the prior art, the signal generator in the embodiment has very low cost.
In this embodiment, the analog start signal provided by the signal generator may comprise an operating voltage of the battery. The voltage value of the voltage signal provided by the signal generator is small and therefore needs to be amplified before being provided as a test signal to the smart battery sensor.
For this purpose, the start signal simulation apparatus further includes an amplification circuit through which the voltage signal supplied from the signal generator is further supplied to the smart battery sensor IBS as a test signal after performing an amplification operation.
As an example, the amplifying circuit is constituted by a voltage dividing circuit, which may include a first resistor R1 and a second resistor R2 connected in series. The voltage division circuit is low in cost and easy to realize.
Wherein the first resistor R1 is connected to the signal generator output, in particular between the positive and negative output of the signal generator, and the second resistor R2 is connected in parallel with the internal resistance R3 of the smart battery sensor IBS.
It will be appreciated by those skilled in the art that the resistance value of the second resistor R2 may be selected to be much greater than the resistance value of the first resistor R1 so that the majority of the voltage is applied to the smart battery sensor. Preferably, the resistance value of the first resistor R1 ranges from 10 to 100 ohms, and the resistance value of the second resistor R2 ranges from 500 to 5000 ohms. More preferably, the ratio of the resistance values of R1 and R2 is 1: 50. as one example, the first resistor R1 has a resistance value of 100 ohms and the second resistor R2 has a resistance value of 5000 ohms.
The invention also relates to a test system comprising the starting signal simulation device and a test method for the intelligent battery sensor. In order to complete the testing process of the intelligent battery sensor, the method implements the following steps:
firstly, an analog start signal of the battery is output by means of a signal generator;
-secondly, performing an amplification operation on the analog start signal output by the signal generator; and
-finally, providing the amplified analog start signal as a test signal to the smart battery sensor.
Further, the test method further comprises:
-reading a measurement value of a smart battery sensor on the basis of the test signal;
-comparing the measured values read by the smart battery sensor with expected values; and
-determining the measurement accuracy of the smart battery sensor by means of the comparison result.
The larger the analog starting signal power output by the signal generator is, the smaller the measurement accuracy of the obtained intelligent battery sensor is; the smaller the analog start signal power output by the signal generator, the greater the measurement accuracy of the resulting intelligent battery sensor.
According to the start signal simulation device for the intelligent battery sensor, provided by the invention, a simulation start signal can be provided in a simple and portable manner, and therefore, the performance test of the intelligent battery sensor is realized. Specifically, the start signal simulation apparatus for a smart battery sensor according to the present invention may output the current and voltage waveforms of a battery at the time of vehicle start by means of an arbitrary signal generator and load the output waveform signal to an IBS through an amplification circuit as its test signal, and the simulation apparatus does not require Integrated Development Environment (IDE) software. Which has a simplified system structure, reduced manufacturing costs, and occupies a small space.
In the present invention, the term "connected" means "electrically connected" or "communicatively connected". Furthermore, the terms "comprises" and "comprising" mean that, in addition to elements directly and explicitly recited in the specification and claims, elements not directly or explicitly recited are excluded from the scope of the present application.
