Description

車用二次鋰電池 Secondary lithium battery for vehicles

本創作涉及汽機車的啟動電池,進一步而言,尤指一種車用二次鋰電池。 The present invention relates to a starter battery for a steam locomotive, and more particularly to a secondary lithium battery for a vehicle.

汽車或機車等交通工具的電力供應系統主要由一發電機、一交/直流轉換模組及一啟動電池組成,交/直流轉換模組的輸入端與該發電機電性連接,交/直流轉換模組的輸出端與啟動電池的電極端子耦接,汽機車的用電設備藉由電導線與啟動電池的電極端子耦接。 The power supply system of vehicles such as automobiles or locomotives mainly consists of a generator, an AC/DC converter module and a starter battery. The input end of the AC/DC converter module is electrically connected to the generator, and the AC/DC converter module is connected. The output end of the group is coupled to the electrode terminal of the starting battery, and the electric device of the steam locomotive is coupled to the electrode terminal of the starting battery by an electric wire.

發電機運轉產生交流電,交/直流轉換模組將交流電轉換為直流電,供應啟動電池的電力儲存及用電設備的用電需求,啟動電池主要是提供汽機車的啟動馬達運轉所需電力,藉由啟動馬達的運轉,啟動汽機車的引擎運轉,引擎的運轉驅動發電機運轉。 The generator operates to generate alternating current, and the AC/DC converter module converts the alternating current into direct current, supplies the power storage of the starting battery and the power demand of the powered device, and the starting battery is mainly to provide the power required for the starting motor of the steam locomotive to operate. Start the operation of the motor, start the engine running of the steam locomotive, and the operation of the engine drives the generator to run.

隨著鋰電池技術趨於成熟,二次鋰電池逐漸應用作為汽機車的啟動電池;二次鋰電池主要具有一蓄電單元、及一充電迴路、一放電迴路及一繼電器,其中,蓄電單元具有數個電池胞(cell),各電池胞串/並聯構成蓄電單元,蓄電單元、充電迴路及放電迴路分別與繼電器電性連接,充電迴路及放電迴路分別控制充/放繼電器的開/斷,據使蓄電單元充/放電。 As lithium battery technology matures, secondary lithium batteries are gradually applied as starting batteries for steam locomotives; secondary lithium batteries mainly have a power storage unit, and a charging circuit, a discharging circuit and a relay, wherein the power storage unit has a number a battery cell, each battery cell serial/parallel constitutes a power storage unit, the power storage unit, the charging circuit and the discharge circuit are electrically connected to the relay, respectively, and the charging circuit and the discharging circuit respectively control the opening/closing of the charging/discharging relay, according to The power storage unit is charged/discharged.

充電迴路於蓄電單元充電時,平衡各電池胞的充電,避免任 一電池胞充電過度而發生危險,並於蓄電單元的電壓上升至額定的高電壓值時,充電迴路控制繼電器斷開,中止對蓄電單元充電,達到過充保護的作用,蓄電單元放電時,當蓄電單元的電壓下降至額定的低電壓值,放電迴路控制繼電器斷開,中止蓄電單元對外放電,避免蓄電單元放電過度,影響蓄電單元的使用壽命,達到過放保護的作用。 When the charging circuit is charged, the charging circuit balances the charging of each battery cell to avoid any When a battery cell is overcharged and dangerous, and when the voltage of the power storage unit rises to a rated high voltage value, the charging circuit control relay is turned off, the charging of the power storage unit is stopped, and the overcharge protection function is achieved, and when the power storage unit is discharged, when The voltage of the power storage unit drops to the rated low voltage value, the discharge loop control relay is turned off, the storage unit is suspended, and the storage unit is prevented from being excessively discharged, which affects the service life of the power storage unit and achieves the function of over-discharge protection.

引擎未運轉的熄火狀態下,繼電器開通,蓄電單元對汽機車的行車電腦、防盜器等用電設備供應電力,發動引擎時,啟動電池對啟動馬達供應電力,待引擎發動運轉並驅動發動機運轉發電後,由於發電機的電壓高於蓄電單元的電壓,在發電機與蓄電單元存在電位差的情況下,發電機對用電設備提供電力,而蓄電單元不放電,但由於發電機運轉發電前,蓄電單元對用電設備及啟動馬達供應電力電,蓄電單元的蓄電下降,故而,發電機提供電力對蓄電單元充電,使蓄電單元的蓄積電力回復至飽滿狀態。 When the engine is not running, the relay is turned on, and the power storage unit supplies power to the electric equipment such as the driving computer and the anti-theft device of the steam locomotive. When the engine is started, the battery is started to supply power to the starting motor, and the engine is started to run and the engine is driven to generate electricity. After that, since the voltage of the generator is higher than the voltage of the power storage unit, in the case where there is a potential difference between the generator and the power storage unit, the power generator supplies power to the power equipment, and the power storage unit does not discharge, but the power is stored before the generator operates. The unit supplies electric power to the electric equipment and the starter motor, and the electric storage unit is reduced in electric storage. Therefore, the electric generator supplies electric power to charge the electric storage unit, and returns the accumulated electric power of the electric storage unit to a full state.

熄火狀態的引擎發動運轉時,二次鋰電池供應啟動馬達運轉所需電力,引擎運轉後,發電機運轉對用電設備供應電力,二次鋰電池停止對用電設備供電,且蓄電單元的蓄電下降,而發電機受引擎帶動運轉發電,發電機對用電設備供應電力,並對二次鋰電池充電,待二次鋰電池回復蓄電飽滿狀態,繼電器斷開,蓄電單元停止充/放電。 When the engine in the flameout state is started, the secondary lithium battery supplies the power required to start the motor operation. After the engine is running, the generator operates to supply power to the power equipment, the secondary lithium battery stops supplying power to the power equipment, and the power storage unit stores power. The generator is driven by the engine to generate electricity. The generator supplies power to the electrical equipment and charges the secondary lithium battery. When the secondary lithium battery returns to the full state of the storage, the relay is disconnected and the storage unit stops charging/discharging.

然而,實務上發現,在某些情況下,當二次鋰電池回復蓄電飽滿狀態,繼電器斷開,蓄電單元停止充/放電時,交/直流轉換模組亦斷開對外放電,此時,雖然發電機保持運轉,用電設備卻無法有效獲得來自於發電機的電力供應,經過一段時間後,交/直流轉換模組由於用電設備的用電需求而再度連通,回復對外放電,用電設備再度獲得來自於發電機的電 力供應,前述交/直流轉換模組斷開的時間雖然極為短暫,卻造成了汽機車在行駛過程中發生短暫的缺電現象,容易造成用電設備使用壽命上的不利影響,且在此短暫的缺電期間,依賴電力作動的動力方向盤無法有效運作,容易引發汽車在行駛中的安全危害。 However, in practice, it is found that, in some cases, when the secondary lithium battery returns to the full state of the storage, the relay is turned off, and the storage unit stops charging/discharging, the AC/DC converter module also turns off the external discharge. The generator keeps running, but the power supply can not effectively obtain the power supply from the generator. After a period of time, the AC/DC converter module is connected again due to the power demand of the power equipment, and the external discharge is restored. Get the electricity from the generator again Force supply, although the time when the AC/DC converter module is disconnected is extremely short, it causes a short power shortage during the running of the steam locomotive, which is likely to cause adverse effects on the service life of the electric equipment, and is short-lived. During the power shortage, the power steering wheel that relies on electric power cannot operate effectively, and it is easy to cause the safety hazard of the car during driving.
