Embodiment 1
[0023] Such as figure 1 As shown, first, use the computer data line to collect the battery voltage (UBat) signal data and the battery current (IBat) signal data from the vehicle's battery management system (BMS) through the interface of the on-board automatic diagnosis system (ie, the OBD interface). Here, the signal data is collected under NEDC operating conditions (NEDC is the operating conditions under the European fuel consumption and emission assessment standards). Of course, it can also be collected under other operating conditions, such as UDC (Urban Cycle Operating Conditions) or EUDC (Suburban) Cycle conditions) and so on.
[0024] The collected signal data is transmitted to the computer through the computer data line, and the computer runs the INCA (Integrated Calibration and Application Tools) software. First, the MaxOf2Input function in the software is used to separate the current signal data into positive current and negative current. The collected current data is c...
