specific Embodiment approach 2

[0035] The evaluation method utilizing the above-mentioned power-type power battery evaluation system for hybrid electric vehicles in this embodiment,

[0036] Step 1. Under the condition that the ambient temperature is 0°C to 40°C, use the power battery performance testing device to test the voltage, current, charging capacity, discharging capacity, acceleration capacity of the whole vehicle to 100 kilometers, and the overall Car starting ability, braking energy recovery ability, energy efficiency, coulombic efficiency ability, temperature and time parameters are tested; among them, energy efficiency refers to the battery discharge power and charging time under constant current conditions, within the same charging and discharging time. The percentage of electricity becomes the energy efficiency of the storage battery; among them, the energy-type power battery performance test device for pure electric vehicles uses the power battery test device produced by Arbin Company of the ...

specific Embodiment approach 3

[0069] Different from the second specific embodiment, in the evaluation method of the power-type power battery evaluation system for hybrid electric vehicles in this embodiment, the process of evaluating the corresponding capabilities of the seven test test data described in step 4 is as follows:

[0070] Evaluation basis: According to the seven ability tests of charging ability, discharging ability, 100km acceleration, vehicle starting ability, braking energy recovery ability, energy efficiency and coulombic efficiency at an ambient temperature of 0°C to 40°C, compare the corresponding performance of each ability at 25°C Based on the test results, the seven-item capability evaluation conclusions of power-type power batteries for hybrid electric vehicles are obtained;

[0071] Evaluation conclusion: compared with the corresponding indicators of each ability at 25°C,

[0072] When the ambient temperature is from 0°C to 10°C, the seven capabilities of charging capacity, discharg...

Abstract

A power-type power cell evaluation system used for a hybrid electric vehicle and an evaluation method belong to the cell evaluation system field. The power-type power cell evaluation system used for the hybrid electric vehicle and the evaluation method lack a basis. The power-type power cell evaluation system used for the hybrid electric vehicle especially comprises a power-type power cell capability evaluation control module used for the hybrid electric vehicle and a power-type power cell capability determination database used for the hybrid electric vehicle. In the power-type power cell evaluation method used for the hybrid electric vehicle, under a normal temperature, a cell capability parameter of a power-type power cell used for the hybrid electric vehicle is tested; tested cell capability test data is transmitted to the power-type power cell capability evaluation control module used for the hybrid electric vehicle; and the power-type power cell capability evaluation control module used for the hybrid electric vehicle calls an evaluation subprogram module to carry out capability evaluation.

Description

technical field [0001] The invention relates to an evaluation system and evaluation method of a power type power battery for a hybrid electric vehicle. Background technique [0002] Power-type power batteries for 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. At present, in the field of hybrid electric vehicles, there is no evaluation basis for the performance test of hybrid electric vehicles, and the corresponding evaluation systems and methods for power-type power batteries for automobiles are still blank. [0003] The battery is used directly, and it is impossible to know whether the existing energy-type power battery meets the needs of pure electric vehicles. Accidents are prone to occur during driving, and the battery cannot be fully utilized...
