【摘要】：隨著全球能源危機(jī)與環(huán)境問題日益加劇，傳統(tǒng)汽車工業(yè)正面臨著前所未有的嚴(yán)峻的挑戰(zhàn)，低能耗、更環(huán)保的新能源汽車成為汽車工業(yè)發(fā)展的趨勢(shì)。純電動(dòng)汽車作為一種新型的節(jié)能環(huán)保汽車，與傳統(tǒng)燃油汽車相比具有低能耗、結(jié)構(gòu)簡(jiǎn)單、振動(dòng)及噪聲低、無污染物排放等優(yōu)點(diǎn)，是未來汽車發(fā)展的一個(gè)重要方向。動(dòng)力電池作為驅(qū)動(dòng)純電動(dòng)汽車唯一的能量源，，對(duì)整車的性能表現(xiàn)有直接影響。鋰離子動(dòng)力電池以其工作電壓高、比能量和比功率大、自放電率低、循環(huán)使用壽命長(zhǎng)、無記憶效應(yīng)、無環(huán)境污染等一系列的優(yōu)點(diǎn)，成為電動(dòng)汽車動(dòng)力電池的首選。 純電動(dòng)汽車在運(yùn)行過程中，其動(dòng)力電池組不斷充放電而產(chǎn)生大量的熱，這些熱量若未及時(shí)散失將導(dǎo)致電池組溫度上升，當(dāng)電池組頻繁大電流放電時(shí)電池組溫升尤為明顯。過高的溫度將影響鋰離子電池組使用性能，降低使用效率和循環(huán)壽命，甚至有可能導(dǎo)致電池永久性失效。因此，電池組充放電時(shí)的溫度必須予以控制。 本文針對(duì)純電動(dòng)汽車用鋰離子動(dòng)力電池組大電流放電時(shí)生熱量過大而導(dǎo)致溫升難以控制的問題，制定了基于電池組過溫的輸出功率控制策略：電池組溫度過高時(shí)，通過適當(dāng)?shù)乜刂破漭敵龉β�，以達(dá)到降低電池組生熱量從而限制電池組溫升的目的。 本文所做的主要工作如下： ①?gòu)募冸妱?dòng)汽車整車動(dòng)力性與經(jīng)濟(jì)性要求出發(fā)，結(jié)合整車基本參數(shù)，對(duì)純電動(dòng)汽車動(dòng)力系統(tǒng)關(guān)鍵參數(shù)進(jìn)行匹配。 ②對(duì)鋰離子動(dòng)力電池的結(jié)構(gòu)、工作原理、特性參數(shù)及生熱特性進(jìn)行了研究與分析，建立了鋰離子電池生熱速率計(jì)算模型。在此基礎(chǔ)上，基于汽車仿真軟件ADVISOR建立了純電動(dòng)汽車鋰離子動(dòng)力電池組仿真模型。 ③針對(duì)純電動(dòng)汽車用鋰離子動(dòng)力電池組在頻繁大電流輸出工況下溫升難以控制的問題，制定了基于電池組過溫的限功率模糊控制策略。同時(shí)，為驗(yàn)證控制策略的有效性，進(jìn)行了多工況下純電動(dòng)汽車性能仿真與分析。
[Abstract]:With the increasing global energy crisis and environmental problems, the traditional automobile industry is facing unprecedented severe challenges, low energy consumption, more environmentally friendly new energy vehicles become the trend of automotive industry development. As a new type of energy saving and environmental protection vehicle, pure electric vehicle (EV) has the advantages of low energy consumption, simple structure, low vibration and noise, no pollutant emission and so on, which is an important direction of future automobile development. As the only energy source for driving pure electric vehicles, power battery has a direct impact on the performance of the whole vehicle. Li-ion power battery has become the first choice of electric vehicle battery because of its high working voltage, high specific energy and specific power, low self-discharge rate, long cycle life, no memory effect, no environmental pollution and so on. During the operation of pure electric vehicle (EV), a large amount of heat is produced by charging and discharging the power battery, which will cause the temperature of the battery to rise if it is not lost in time, especially when the battery is discharging frequently with high current. If the temperature is too high, it will affect the performance of lithium ion battery, reduce the efficiency and cycle life, and even lead to the permanent failure of the battery. Therefore, the battery charge and discharge temperature must be controlled. In this paper, the output power control strategy based on excessive temperature of lithium ion battery pack for pure electric vehicle, which is caused by excessive heat generation during large current discharge and difficult to control the temperature rise, is developed: when the battery pack temperature is too high, the output power control strategy is proposed in this paper. By properly controlling the output power, the heat generation of the battery pack is reduced and the temperature rise of the battery pack is limited. The main work of this paper is as follows: According to the requirements of power and economy of pure electric vehicle and the basic parameters of the whole vehicle, the key parameters of the power system of pure electric vehicle are matched. (2) the structure, working principle, characteristic parameters and heat generation characteristics of Li-ion battery are studied and analyzed, and the calculation model of heat generation rate of Li-ion battery is established. On this basis, the simulation model of lithium ion battery pack of pure electric vehicle is established based on the vehicle simulation software ADVISOR. In order to solve the problem that the temperature rise of Li-ion power battery for pure electric vehicle is difficult to control under the condition of frequent and high current output, a power limiting fuzzy control strategy based on overtemperature of battery pack is developed. At the same time, in order to verify the effectiveness of the control strategy, the performance simulation and analysis of pure electric vehicle under multiple working conditions are carried out.
