Abstract

The invention provides a hybrid-power-automobile-used power type power battery evaluation system suitable for cold regions and a method thereof, relates to a power battery evaluation system and a method thereof, aims at solving problems that a hybrid-power-automobile-used power type power battery under the low-temperature environment of the cold regions lacks evaluation basis, and provides the hybrid-power-automobile-used power type power battery evaluation system suitable for the cold regions and the method thereof. The system comprises a battery capacity evaluation control module and a database. The method is realized through the following steps that step one, temperature of a low-temperature box is set; step two, the hybrid-power-automobile-used power type power battery is placed in the low-temperature box; step three, seven test and experiment data are tested; step four, the seven test and experiment data are transmitted to the database; step five, the evaluation criteria of the seven test and experiment data are obtained; and step six, low temperature capacity of the seven test and experiment data is respectively evaluated. The hybrid-power-automobile-used power type power battery evaluation system suitable for the cold regions and the method thereof are applied to the field of power battery evaluation.

Description

technical field [0001] The invention relates to an evaluation system and method for a power type power battery for a hybrid electric vehicle, in particular to an evaluation system and method for a power type power battery for a hybrid electric vehicle adapted to cold regions. Background technique [0002] Hybrid vehicles usually use power-type power batteries to start the motor and power battery system when starting, climbing and accelerating. The power-type power battery of a hybrid electric vehicle plays the role of short-term power output to ensure the power of the vehicle. [0003] At present, in the field of electric vehicles, there is a lack of evaluation basis for the ability test of hybrid electric vehicles in low temperature environments in cold regions. At present, the evaluation system and method of power type power batteries for hybrid electric vehicles in cold regions lack the ability to accelerate to 100 kilometers in low temperature environments, The starting...
