Description
本發明係有關於一種充電器，特別是指一種可切換正常充電與快速充電之切換式充電器。 The invention relates to a charger, in particular to a switchable charger capable of switching between normal charging and fast charging.
能源是國民經濟的基本支撐，是現代社會賴以生存的基礎。但是，現今因受到油價飆漲及石化能源可用年限有限等影響，有許多專家預測再過五十年，地球上的石油便將會消耗殆盡。加上地球環境污染日益嚴重，尤其是空氣污染，已造成地球生態的嚴重問題，近幾年由於能源危機與環保意識的抬頭，許多科技廠商紛紛研發出許多減少環境污染並且有環境保護概念的產品。現今國際環保意識抬頭，對空氣品質的要求與日俱增，由環保署之報告顯示，一台50cc機車所排放之一氧化碳是一輛2000cc汽車的2.7倍之多，可見機車是主要的移動性污染源，因此對此污染源之控制已是刻不容緩之地步。 Energy is the basic support of the national economy and the basis for the survival of modern society. However, due to the impact of soaring oil prices and limited availability of petrochemical energy, many experts predict that in the next 50 years, the oil on the planet will be exhausted. Coupled with the increasing environmental pollution of the earth, especially air pollution, it has caused serious problems in the earth's ecology. In recent years, due to the rise of energy crisis and environmental awareness, many technology manufacturers have developed many products that reduce environmental pollution and have environmental protection concepts. . Nowadays, the international environmental awareness is on the rise, and the requirements for air quality are increasing day by day. According to the report of the Environmental Protection Agency, the carbon oxide emitted by a 50cc locomotive is 2.7 times that of a 2000cc vehicle. It can be seen that the locomotive is the main source of mobile pollution. The control of this source of pollution is no longer a matter of urgency.
隨著經濟的發展，以及目前交通發展的趨勢，工商業交流熱絡，加上人口成長快速，使交通量急速增加，在地狹人稠的台灣，對機車的使用率尤其普遍，而機車的廢氣排放即成為空氣污染的主要來源，且機車所排放之廢氣又比汽車之排放量高出許多，為了有效減少機車排放廢氣，而解決造成空氣污染的問題，唯有大力發展電動機車，才能降低環境污染的源頭。石油總有一天會用完，地球只有一個，是現在世界環境保護的主流共識，因此以乾淨能源取代石油為主的電動汽機車一定是未來要走的一條路。 電動機車由於無引擎排放廢氣噪音、振動、燙傷等缺點，同時可減輕對石油之依賴，是適合發展取代傳統機車的代步工具。然而，電池的充電快速與否、安全、壽命是電動機車成功與否的主因。 With the development of the economy and the current trend of transportation development, the exchange of industry and commerce, coupled with rapid population growth, has led to a rapid increase in traffic volume. In Taiwan, where the use of locomotives is particularly prevalent, the use of locomotives is particularly prevalent. Emissions become the main source of air pollution, and the emissions from locomotives are much higher than those of automobiles. In order to effectively reduce the emissions of locomotives and solve the problem of air pollution, only by vigorously developing electric locomotives can the environment be reduced. The source of pollution. Oil will one day run out. There is only one earth, which is the mainstream consensus of the world's environmental protection. Therefore, electric steam locomotives that replace oil with clean energy must be the way to go in the future. Due to the lack of engine exhaust noise, vibration, burns and other shortcomings, the electric motor vehicle can reduce the dependence on oil and is a suitable tool for the development of replacing traditional locomotives. However, the fast charging, safety and longevity of the battery are the main reasons for the success of the electric motor car.
現今電動機車的使用上最為讓民眾怯步的，其是充電電池充電速度過慢。此外，電動機車常常因外出，如果使用太久則有可能發生電池沒有電量之情形，在沒有電量的同時要如何進行電源補給也是問題之一。針對此問題則有人提出利用便利商店當作電動機車充電站，但由於電池充電時間過長而為導致無法推廣電動機車之主因，而且現階段的電動機車電池還是以鉛酸電池為主，在短時間內將電能傳進鉛酸電池中儲存時，在這過程中會導致電池溫度快速上升並產生激烈的電能化學反應而形成電池內部壓力與氣體，如此會降低電池壽命也會造成無效電能的產生。 Nowadays, the use of electric motor cars is the most popular for people. It is that the charging battery is charging too slowly. In addition, the electric motor car often goes out. If it is used for too long, there is a possibility that the battery does not have a power. How to perform power supply replenishment without power is also one of the problems. In response to this problem, it has been proposed to use the convenience store as a charging station for electric motor vehicles. However, due to the long charging time of the battery, the main reason for the inability to promote the electric motor is that the current electric vehicle battery is mainly lead-acid battery, which is short. When the energy is transferred into the lead-acid battery for storage in the process, the battery temperature rises rapidly and a strong electrical chemical reaction is generated to form the internal pressure and gas of the battery, which will reduce the battery life and cause the generation of invalid electric energy. .
由上述可知，現今想要推展電動機車，卻有續航力不足及充電耗時過長等問題存在，因此設計一體積小以便能放置於電動機車上，且能對充電電池快速充電之充電器為現今發展電動機車之重要的課題之一。 It can be seen from the above that there is a problem that the electric motor vehicle is currently being promoted, but there are problems such as insufficient endurance and long charging time. Therefore, a charger that can be placed on the electric motor vehicle and can quickly charge the rechargeable battery is nowadays. One of the important topics in the development of electric motor vehicles.

請參閱第二圖，係本發明之控制電路之一較佳實施例的方塊圖。如圖所示，控制電路19包含一電源模組190、一靜態隨機存取記憶體(SRAM)191、一快閃記憶體192、一直接記憶體存取控制器(DMA)193、一微處理器194、一並列輸入/輸出埠(PIO)195、一唯讀記憶體(ROM)196、一顯示介面197與一通用非同步收發傳輸器(UART)198。電源模組190用於提供電源給控制電路19內部之電子元件。靜態隨機存取記憶體191、快閃記憶體192與唯讀記憶體196耦接於微處理器194，以供微處理器194讀取資料或程式而執行。唯讀記憶體196係儲存啟動程式，以供微處理器194讀取而執行，以進行啟動初始化程序。本發明之控制電路19是藉由脈波寬度調變(PWM)之方式控制第一充電驅動電路16與第二充電驅動電路17，快閃記憶體192即用於儲存脈波寬度調變之相關程式，以供微處理器194讀取而執行。 Please refer to the second figure, which is a block diagram of a preferred embodiment of the control circuit of the present invention. As shown, the control circuit 19 includes a power module 190, a static random access memory (SRAM) 191, a flash memory 192, a direct memory access controller (DMA) 193, and a micro processing. 194, a parallel input/output port (PIO) 195, a read only memory (ROM) 196, a display interface 197 and a universal asynchronous transmit transceiver (UART) 198.

The read-only memory 196 stores the boot program for reading by the microprocessor 194 for boot initialization.

The program is executed for reading by the microprocessor 194.
復參閱第二圖，微處理器194更耦接並列輸入/輸出埠195與通用非同步收發傳輸器198，以接收與傳輸資料與訊號。微處理器194更耦接直接記憶體存取控制器193，直接記憶體存取控制器193為一存取介面，其可直接將記憶體中的資料與輸入輸出設備作存取動作，而降低了微處理器194的輸入輸出工作量。直接記憶體存取控制器193允許輸入輸出設備與記憶體之間直接轉移資料，而不需經由微處理器194的參與。在週邊設備與記憶體之間需要大量資料轉移時，此種方式可說是一種不需要中斷服務程式的中斷服務，直接由硬體完成此特定的工作，節省了許多程式執行的時間，所以可有效降低微處理器194的輸入輸出工作量。微處理器194更耦接顯示介面198，以傳輸第一充電電路13或第二充電電路14之充電狀態至顯示介面198，以控制顯示器23顯示。如此，使用者即可透過顯示器23得知第一充電電路13或第二充電電路14之充電狀態，以及得知目前充電電池12之電量。 Referring to the second figure, the microprocessor 194 is further coupled to the parallel input/output port 195 and the universal asynchronous transceiver 198 for receiving and transmitting data and signals.

The input and output workload of the microprocessor 194. The direct memory access controller 193 allows direct transfer of data between the input and output devices and the memory without the involvement of the microprocessor 194. When a large amount of data transfer is required between the peripheral device and the memory, this method can be said to be an interrupt service that does not need to interrupt the service program, and the specific work is directly performed by the hardware, which saves a lot of program execution time, so The input and output workload of the microprocessor 194 is effectively reduced.

本發明之切換式充電器係依據一正常充電曲線與一快速充電曲線，而 對充電電池12進行正常充電或者快速充電，即控制電路19依據正常充電曲線與快速充電曲線控制第一充電電路13與第二充電電路14，以對充電電池12進行正常充電或者快速充電。本發明所依據之正常充電曲線為一般常用之充電曲線，所以本發明再此即不多加以贅述。以下係配合第三圖與第四圖，而說明本發明之控制電路19如何進行快速充電。 The switching charger of the present invention is based on a normal charging curve and a fast charging curve. The rechargeable battery 12 is normally charged or rapidly charged, that is, the control circuit 19 controls the first charging circuit 13 and the second charging circuit 14 according to the normal charging curve and the fast charging curve to perform normal charging or fast charging of the rechargeable battery 12. The normal charging curve according to the present invention is a commonly used charging curve, so the present invention will not be repeated here. The following is a description of how the control circuit 19 of the present invention performs fast charging in conjunction with the third and fourth figures.
請一併參閱第三圖與第四圖，係本發明切換式充電器之一較佳實施例的快速充電流程圖與曲線圖。如圖所示，首先進行步驟S1，進行初始化，此步驟係量測充電電池12目前之電量，以及充電電池12之外殼溫度。之後，如步驟S2所示，判斷充電電池12是否安全，如不安全則進行步驟S14，而結束充電，以免發生危險。此步驟係依據充電電池12之溫度進行判斷，若充電電池12之溫度超過一預定溫度，即表示充電電池12並不適合進行充電，而進行步驟S14，而結束充電，以免發生危險。本發明之預定溫度之一實施例為45度，但不侷限本發明之預定溫度僅能為45度。此外，此步驟更會進一步判斷充電電池12之儲存電量是否飽合，若充電電池12之儲存電量為飽和，即執行步驟S14而不需要進行充電。 Please refer to the third and fourth figures together, which is a quick charging flow chart and a graph of a preferred embodiment of the switching charger of the present invention. As shown in the figure, step S1 is first performed to perform initialization. This step measures the current power of the rechargeable battery 12 and the temperature of the outer casing of the rechargeable battery 12. Thereafter, as shown in step S2, it is judged whether or not the rechargeable battery 12 is safe. If it is not safe, step S14 is performed, and charging is terminated to avoid danger. This step is judged according to the temperature of the rechargeable battery 12. If the temperature of the rechargeable battery 12 exceeds a predetermined temperature, it means that the rechargeable battery 12 is not suitable for charging, and the process proceeds to step S14, and the charging is terminated to avoid danger. One embodiment of the predetermined temperature of the present invention is 45 degrees, but is not limited to the predetermined temperature of the present invention of only 45 degrees. In addition, this step further determines whether the stored power of the rechargeable battery 12 is saturated. If the stored power of the rechargeable battery 12 is saturated, step S14 is performed without charging.
然後，如步驟S3所示，檢測充電電池12的端電壓U並傳送至控制電路19。接著，如步驟S4所示，控制電路19判斷充電電池12內的含電量是否大於一第一門檻電壓U2，即如第四圖所示，判斷充電電池12的端電壓U是否大於第一門檻電壓U2。若如第四圖所示，充電電池12的端電壓U之起初電壓為U1，而小於第一門檻電壓U2時，則進行步驟S5，以對充電電池12進行預充電，直到充電電池12的端電壓U大於第一門檻電壓U2。由於，對長期不用的充電電池，新充電電池或充電初期已處於深度放電狀態的充電電池進行充電時，若一開始就用大電流快速充電是會影響充電電池12之使用壽命。因此，若充電電池12之起初電壓為U1並小於第一門檻電壓U2時，進行步驟S6而一開始先施行穩定小電流I1對充電電池12進行充電，讓充電電池12之電 壓U上升，直到充電電池12的端電壓U大於第一門檻電壓U2。如此，可延長充電電池12之使用壽命。 Then, as shown in step S3, the terminal voltage U of the rechargeable battery 12 is detected and transmitted to the control circuit 19. Then, as shown in step S4, the control circuit 19 determines whether the power content in the rechargeable battery 12 is greater than a first threshold voltage U2, that is, as shown in the fourth figure, determining whether the terminal voltage U of the rechargeable battery 12 is greater than the first threshold voltage. U2. If the initial voltage of the terminal voltage U of the rechargeable battery 12 is U1 and less than the first threshold voltage U2 as shown in the fourth figure, step S5 is performed to precharge the rechargeable battery 12 until the end of the rechargeable battery 12 The voltage U is greater than the first threshold voltage U2. Since, for a rechargeable battery that has not been used for a long time, a new rechargeable battery or a rechargeable battery that has been in a deep discharge state at the beginning of charging, charging with a large current at the beginning may affect the service life of the rechargeable battery 12. Therefore, if the initial voltage of the rechargeable battery 12 is U1 and less than the first threshold voltage U2, step S6 is performed and the stable small current I1 is first applied to charge the rechargeable battery 12 to charge the rechargeable battery 12. The voltage U rises until the terminal voltage U of the rechargeable battery 12 is greater than the first threshold voltage U2. Thus, the life of the rechargeable battery 12 can be extended.
當充電電池12的端電壓U大於第一門檻電壓U2時，則如步驟S6所示，進行脈衝快速充電，其是在先前預充電階段，讓充電電池12之端電壓U上升到第一門檻電壓U2，接著利用較大充電電流I4對充電電池12進行脈衝快速充電，並且隨著充電電池12之電量的增加，即端電壓U逐漸升高，讓充電電流由較大充電電流I4等級開始降低到較小充電電流I5與I6，使充電電流的脈衝幅度與寬度隨著充電電池12的端電壓U升高而分級減少，這樣一來可防止充電接近飽和時，而產生振盪現象及過度充電之問題。 When the terminal voltage U of the rechargeable battery 12 is greater than the first threshold voltage U2, then as shown in step S6, pulse fast charging is performed, which is to increase the terminal voltage U of the rechargeable battery 12 to the first threshold voltage in the previous pre-charging phase. U2, then the rechargeable battery 12 is rapidly charged by the larger charging current I4, and as the amount of the rechargeable battery 12 increases, the terminal voltage U gradually rises, so that the charging current is reduced from the larger charging current I4 level to The smaller charging currents I5 and I6 cause the pulse amplitude and width of the charging current to be stepped down as the terminal voltage U of the rechargeable battery 12 rises, thereby preventing the phenomenon of oscillation and overcharging when the charging is near saturation. .
此外，於進行步驟S6之充電過程，係會進行步驟S7、S8與S9，檢視充電電池12之端電壓U，以判斷充電電池12之端電壓U是否小於一第二門檻電壓U3。若充電電池12之端電壓U是否小於第二門檻電壓U3時，則接續進行脈衝快速充電。但，再接續進行脈衝快速充電之前，必須先檢測充電電池12的溫度，如果充電電池12之溫度大於45度，則結束充電。若充電電池12之溫度未大於45度，則接續進行脈衝快速充電。如此，可避免充電電池12因快速充電而發生溫度過高之情形，而影響充電電池12之使用壽命。上述之45度僅為本發明之一實施方式，並非限制本發明僅能依據45度進行判斷。 In addition, in the charging process of step S6, steps S7, S8 and S9 are performed to check the terminal voltage U of the rechargeable battery 12 to determine whether the terminal voltage U of the rechargeable battery 12 is less than a second threshold voltage U3. If the voltage U of the terminal of the rechargeable battery 12 is less than the second threshold voltage U3, the pulse fast charging is continued. However, before the pulse fast charging is continued, the temperature of the rechargeable battery 12 must be detected first. If the temperature of the rechargeable battery 12 is greater than 45 degrees, the charging is terminated. If the temperature of the rechargeable battery 12 is not greater than 45 degrees, the pulse fast charging is continued. In this way, the situation that the rechargeable battery 12 is overheated due to rapid charging can be avoided, and the service life of the rechargeable battery 12 is affected. The above 45 degrees is only one embodiment of the present invention, and the present invention is not limited to the determination based on 45 degrees.
承接上述，若如第四圖所示，充電電池12之端電壓U是否大於第二門檻電壓U3時，即如步驟S10所示，對充電電池12進行補足充電。由於上述之脈衝快速充電終止後，充電電池12並不一定充足電量，為了保證充電電池12充入100%的電量，本發明對充電電池12還要進行補足充電。此階段之充電方式係採用恆壓充電，可使充電電池12之電量快速恢復，此時充電電流I會逐漸降低。上述進行補足充電之過程，係會進行步驟S11，判斷充電電流I是否小於一門檻電流I2，若充電電流I未小於門檻電流I2時，則接續 進行補足充電，直至充電電流I小於一門檻電流I2。 In the above, if the terminal voltage U of the rechargeable battery 12 is greater than the second threshold voltage U3 as shown in the fourth figure, the rechargeable battery 12 is fully charged as shown in step S10. Since the above-mentioned pulse fast charging is terminated, the rechargeable battery 12 is not necessarily fully charged. In order to ensure that the rechargeable battery 12 is charged with 100% of the power, the rechargeable battery 12 of the present invention is further charged. The charging method at this stage is to use constant voltage charging, so that the power of the rechargeable battery 12 can be quickly recovered, and the charging current I will gradually decrease. In the above process of making up the charging, the process proceeds to step S11 to determine whether the charging current I is less than a threshold current I2. If the charging current I is not less than the threshold current I2, then the connection is continued. Make up the charge until the charging current I is less than a threshold current I2.
承接上述，當充電電流I小於一門檻電流I2時，則如步驟S12所示，對充電電池12進行浮充電，其是用來補充充電電池12自放電所消耗的電量，其只要充電電池12接在本發明之充電器上，並且充電器接通電源11，第一充電電路13就會對充電電池12不斷補充電荷，這樣可使充電電池12處於充足電量之狀態。此步驟之充電電流I是非常小，而接近門檻電流I2。上述進行浮充電之過程，係會如步驟S13所示，判斷充電電池12之溫度，若充電電池12之溫度未大於45度，則回到步驟S12進行浮充電，如果充電電池12之溫度大於45度，則結束對充電電池12進行充電。 In the above, when the charging current I is less than a threshold current I2, the rechargeable battery 12 is floated as shown in step S12, which is used to supplement the self-discharge of the rechargeable battery 12, as long as the rechargeable battery 12 is connected. In the charger of the present invention, and the charger is powered on, the first charging circuit 13 constantly recharges the rechargeable battery 12, so that the rechargeable battery 12 is in a state of sufficient power. The charging current I at this step is very small, and is close to the threshold current I2. In the above process of performing floating charging, the temperature of the rechargeable battery 12 is determined as shown in step S13. If the temperature of the rechargeable battery 12 is not greater than 45 degrees, the process returns to step S12 for floating charging, if the temperature of the rechargeable battery 12 is greater than 45. Then, the charging of the rechargeable battery 12 is ended.
由上述可知，本發明之控制電路19會依據充電電池12之端電壓、第一充電電路13之充電電流與充電電池12之溫度，而控制第一充電電路13對充電電池12充電之狀態。因此，可有效避免充電電池12因為快速充電而影響使用壽命，而可有效延長充電電池12之使用壽命。 As can be seen from the above, the control circuit 19 of the present invention controls the state in which the first charging circuit 13 charges the rechargeable battery 12 in accordance with the voltage of the terminal of the rechargeable battery 12, the charging current of the first charging circuit 13, and the temperature of the rechargeable battery 12. Therefore, the rechargeable battery 12 can be effectively prevented from affecting the service life due to rapid charging, and the service life of the rechargeable battery 12 can be effectively extended.
此外，第四圖下方係顯示本發明第一圖實施例中之放電電路15的放電狀態。放電電路15用於在充電電池12充飽電力之後，而藉由放電電路15快速調查充電電池12之放電時間。 Further, the lower portion of the fourth figure shows the discharge state of the discharge circuit 15 in the embodiment of the first embodiment of the present invention. The discharge circuit 15 is for quickly investigating the discharge time of the rechargeable battery 12 by the discharge circuit 15 after the rechargeable battery 12 is fully charged.
