Abstract

The invention, which belongs to the new energy automobile field, relates to a simulation method of a new energy automobile power cell and an apparatus thereof. The method and the apparatus can be applied for test verification and design improvement of a whole car controller, a cell management system and a motor controller. The method comprises: simulation instructions concerning a voltage, a current and a cell temperature and the like are sent out by a computer; and a power cell simulator outputs a corresponded monomer voltage, a corresponded total voltage, a corresponded current and a corresponded cell temperature. The apparatus comprises a power cell simulator, a computer, software and a controller area network (CAN) communication interface, wherein the software is operated on the computer. The power cell simulator includes a temperature daughter board, a voltage daughter board, a current daughter board and an MCU. The MCU is used for controlling a temperature output of the temperature daughter board, a voltage output of the voltage daughter board and a current output of the voltage daughter board, coordinating work between all the daughter boards and receiving a command message from the CAN communication interface and making corresponded motions. The computer software is used for reading whole automobile condition data with a fixed format and data edited manually. And the CAN communication interface is used for communication between the power cell simulator and the computer. According to the invention, a power cell is simulated; power cell packaging can be avoided; costs can be reduced; and efficiency of controller development can be improved.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to a method and device for simulating a power battery.
