I am working in a project which requires to measure accurate battery DC voltage and internal resisitance, these readings will be read by a microcontoller (microcontroller selection not yet determined) however output of the requested circuit levels will be matched with suitable controller (suggestions for possible controllers are welcomed). 1. DC voltmeter requirements: High impedence voltmeter is required to read battery voltage (FET input or equivelant). 1.1: voltmeter to read 12V battery, voltmeter range is 9V-15V. 1.2: voltmeter to read 6V battery, voltmeter range is 4.5V-7.5V. 1.3: voltmeter to read 2V battery, voltmeter range is 1.5V-2.5V. *accurecy of voltmeter to be provided. 2. Internal resistance requirements: 2.1: 12V battery internal resistance measurement circuit. Reading range is 1.5mOhm-100mOhm. 2.2: 6V battery internal resistance measurement circuit. Reading range is 0.8mOhm-80mOhm. 2.3: 2V battery internal resistance measurement circuit. Reading range is 0.1mOhm-20mOhm. Note: 1. Three models are required for each reading range. For example 12V battery model is required to have voltmeter and internal resistance of 12V range. 2. An option to power on the microcontroller from battery voltage to be added, taking into considration controller input voltage acceptable voltage window and the module should have (if mandatory) a circuit to convert input voltage to match controller acceptable voltage range. Please contact me if you require further clarifications.
