Research On Hybrid Power Armored Vehicles Power Grid Parameters Test System

Power flow testing and battery energy technology research according to the maincontroller commands and system control strategy of hybrid vehicle engine, electric motors,main suspension, electric chemical artillery, storage battery and DC-DC converter decives,such as battery energy one of the power flow and power source of the real-time monitoring, tomaster the various equipment power flow conversion and loss under different workingconditions. According to the test results, designers can take appropriate measures to preventthe adverse effects when the peak current, surge voltage, high-power electrical equipment isstarted on the system, to prevent the poor battery performance affect vehicle dynamics, so asto optimize the vehicle performance.This thesis is set in the hybrid power armored vehicletanks, on which the network parameters(power flow and battery power) testing technology isstudied, through the current and voltage detection module, for each input and output voltageelectrical equipment, and current of electrical equipment and the total voltage charge anddischarge voltage and current of battery collection, storage, data processing, vehicle powerflow conversion model is established, power flow of vehicle conversion, the efficiency andperformance of the battery are analyzed.In this paper, according to the power grid parametric testing system of modular designideas, from both hardware and software design of this to test the functionality of the system isexpounded. The system is mainly composed of sensors, the power management circuit, signalconditioning circuit, USB readout circuit, and computer, etc. The hardware part mainly usedFPGA to realize the system logic sequential control and data storage, grid parameters in thetest system is achieved after the completion of the characteristics of the data is not lost whenpower supply drop.Based on hybrid power armored vehicles power grid parameter analysis of the test results,show that the hybrid armored vehicles grid parameters test system meant the requirementmentioned in the overall design of the indicators.
