APPARATUS FOR MONITORING BATTERY VOLTAGE AND TEMPERATURE

Title:

APPARATUS FOR MONITORING BATTERY VOLTAGE AND TEMPERATURE

Document Type and Number:

WIPO Patent Application WO/2010/057429

Kind Code:

A1

Abstract:

An apparatus for monitoring battery voltage and temperature includes a host controller and collection boards, and every collection board for the battery includes a voltage collection module, a temperature collection module, a host control chip MCU, A/D transformation module, an opto-couple isolation module, a CAN bus communication module and two external connection ports CN1, CN2. The input of the A/D transformation module is connected with the output of the voltage collection module and the temperature collection module, and the output of the A/D transformation module is connected with the opto-couple isolation module via SPI bus, and the I/O port of the SPI bus module in the host control chip MCU is connected with the opto-couple isolation module, and the host control chip MCU is connected with the CAN bus communication module of the host controller via the CAN bus communication module, and the collection boards are connected in turn via socket piece.
