battery self discharge rate of the capacitor detection device and method

摘要

this invention is a battery electric vehicle in use, especiallyelectric car for a long time, long time parking or running operation when the display of the battery residual capacity is calculated by the majority of dogs can be composed so that the battery temperature is input to the input part (20) and a battery voltage input part (1) 0) and temperature input part (20) to output the analog signal to the train station, the stability of the filter and the output of the filter part to the station (30) and a low pass filter part (30) in the output of the analog signal to a digital signal to convert and output to a / d conversion part (40). the a / d conversion part (40) to the output of the digital signal to a control signal input connected to the output (50) and the company; my company (50) in the output of the control signal by the input calibration data for the above. the company (50) output to the memory part (60); my company (50) of the system when the input signal.battery related information CAN and rs - 232C according to the external control device to the output contact (70); and the power supply of a company (50) of the operation state information, the exception occurs when the reset to the uac10uc2dcubd80 (80). my company (50) in the output of digital signal input connected to the analog signal to convert the output to the d / a conversion part (90), including the characteristics of the area, such as the battery of the invention is to grasp the state of the equipment can be used, ubc30ud130. due to lack of the capacity of the drive is not a waste of time is not effective.
