Vehicle battery performance testing method and vehicle battery performance testing system

Abstract

The invention discloses a vehicle battery performance testing method and a vehicle battery performance testing system. The vehicle battery performance testing method comprises the following steps of S1, on the condition that an on-vehicle terminal detects finishing of high-voltage connection, recording data on the on-vehicle terminal; S2, on the condition that the on-vehicle terminal detects vehicle charging or normal driving, performing recording in a charging management table or operation management table; S3, after the on-vehicle terminal finishes data recording, performing data packing and transmitting data packages to a remote vehicle database server; S4, after the server receives the data, checking the data for determining whether the data are effective and reliable, if yes, updating the server database, and otherwise, abandoning the data; S5, analyzing the battery state by a monitoring center, obtaining a safe operation range, when the battery state is not in the safe operation range, performing a next step, and otherwise, keeping the battery state in the safe operation range; and S6, if the battery state of a certain vehicle is not in the safe operation range, taking a corresponding measure. The vehicle battery performance testing method and the vehicle battery performance testing system can perform comprehensive analysis on the battery performance of an electric vehicle, thereby better ensuring performance of the electric vehicle.

Description

technical field [0001] The invention relates to the technical field of battery performance testing, in particular to a vehicle battery performance testing method and system thereof. Background technique [0002] With the lowering of the entry threshold for pure electric vehicles, more and more companies are participating in the R&D and production of pure electric vehicles. Pure electric vehicles are limited by battery conditions. Under the influence of temperature, high-power charge and discharge, and the number of charge and discharge cycles, the battery performance is easy to decay, and the power and battery life of electric vehicles will be reduced. Various test confirmations before the vehicle goes on the market help the research and development personnel to fully understand the vehicle performance. In order to reduce the workload of the test personnel, the R&D personnel read the vehicle data through the remote monitoring center, and obtain / calculate the battery perform...

Problems solved by technology

The advantages of this patent: It provides an effective management method for the demonstration operation of newly developed vehicles, improves the test level and quality of new vehicles, and also provides important reference data for the continuous improvement of the quality of new vehicles in real time and accurately; the disadvantage of this patent: only collection Test data cannot automatically and conveniently analyze battery performance

The advantages of this patent: only one discharge test of the battery is required during the road test, and the rest of the test work can be completed in the laboratory by connecting the battery to be tested to the load, which reduces the manpower and material resources consumed in the process of battery performance testing ; The disadvantage of this patent: the hardware device for collecting data can only store the data in the storage device, and cannot realize remote reading of data
