The battery monitoring and protection system 100 is applied to a vehicle, including a battery module 10 and a battery monitoring and protection device 20, and a battery. The monitoring and protection device 20 is configured to monitor the tilt angle of the battery module 10, whether there is water immersion or liquid leakage, and thereby control the power supply of the battery module 10 to maintain the safety of the vehicle.

電池模組10包括一用以儲存電能的電池單元11，該電池單元11可為車輛的一電池箱或任何儲存元件，用以儲存電能或釋放電能至車輛的一主系統電路200，例如：引擎、音響等。電池模組10還包括一電連接電池單元11及主系統電路200之間的切換單元12，該切換單元12受控於電池監控及保護裝置20而在一使電池單元11與主系統電路200電連接的導通狀態，以及一使電池單元11與主系統電路200不電連接(即斷路)的非導通狀態之間切換。 The battery module 10 includes a battery unit 11 for storing electrical energy. The battery unit 11 can be a battery box or any storage component of the vehicle for storing electrical energy or releasing electrical energy to a main system circuit 200 of the vehicle, such as an engine. , audio, etc. The battery module 10 further includes a switching unit 12 electrically connected between the battery unit 11 and the main system circuit 200, the switching unit 12 being controlled by the battery monitoring and protection device 20 to electrically connect the battery unit 11 and the main system circuit 200.

電池監控及保護裝置20包含一控制模組21及一電連接於控制模組21的感測模組22，在本實施例中，感測模組22包括一加速度感測單元221、一溫濕度感測單元222、一氣體感測單元223及一電力感測單元224。 The battery monitoring and protection device 20 includes a control module 21 and a sensing module 22 electrically connected to the control module 21. In the embodiment, the sensing module 22 includes an acceleration sensing unit 221, a temperature and humidity. The sensing unit 222 , a gas sensing unit 223 and a power sensing unit 224 .

控制模組21為一微控制器(MCU)，其電連接於電池模組10的切換單元12，用以根據感測模組22的感測結果， 控制切換單元12在導通狀態及非導通狀態之間切換。 The control module 21 is a microcontroller (MCU) electrically connected to the switching unit 12 of the battery module 10 for sensing the sensing result of the sensing module 22, The control switching unit 12 switches between an on state and a non-conduction state.

加速度感測單元221為一陀螺儀感測晶片(Chip)，其可以感測靜態重力加速度、透過三軸(X、Y、Z軸)變化檢測有無運動發生、可感測任意方向的振動以進行敲擊檢測、可感測車輛是否正在掉落以進行自由落體檢測等，本實施例之加速度感測單元221可選擇的感測範圍達±16G，且電連接於控制模組21，用以感測電池模組10的傾角(相對於X、Y、Z軸)變化並對應產生一傾斜角度與撞擊力道變化並對應產生一加速度訊號，使得控制模組21根據該傾斜角度或該加速度訊號切換切換單元12的狀態，進而控制電池模組11供電與否。舉例來說，若加速度感測單元221感測到電池模組10處於傾斜狀態(例如：傾斜角度大於45度以上)，或者處於傾倒狀態(例如：車輛翻滾)，亦或者車輛已掉落山谷、落海等落下狀態或遭受撞擊時，控制模組21會將切換單元12切換至非導通狀態，以切斷電池單元11的電力輸出，以保護主系統電路200的安全。 The acceleration sensing unit 221 is a gyro sensing chip (Chip) that can sense static gravitational acceleration, detect the presence or absence of motion through three-axis (X, Y, Z-axis) changes, and can sense vibration in any direction. The sensing unit 221 can select a sensing range of ±16 G and is electrically connected to the control module 21 for sensing. The tilt angle (relative to the X, Y, and Z axes) of the battery module 10 is changed, and an inclination angle and an impact force path are generated correspondingly to generate an acceleration signal, so that the control module 21 switches according to the tilt angle or the acceleration signal. The state of the unit 12, in turn, controls whether the battery module 11 is powered or not. For example, if the acceleration sensing unit 221 senses that the battery module 10 is in a tilt state (for example, the tilt angle is greater than 45 degrees), or is in a dumping state (for example, a vehicle rollover), or the vehicle has fallen into the valley, When the sea is in a falling state or subjected to an impact, the control module 21 switches the switching unit 12 to a non-conducting state to cut off the power output of the battery unit 11 to protect the safety of the main system circuit 200.

溫濕度感測單元222電連接於控制模組21，用以感測電池模組10的溫度與濕度變化並對應產生一溫溼度訊號，使得控制模組21根據該溫溼度訊號切換切換單元12的狀態，進而控制電池模組11供電與否。換句話說，溫濕度感測單元222可以感測電池模組10中是否有浸水、或是所擺放的位置是否過於潮濕等情況，以避免電池單元11的接點或金屬接點(圖未示)長期處於潮濕環境而導致發生金屬氧化生鏽腐蝕或漏電。若控制模組21判斷電池模組10的溫度 或濕度出現異常，例如：濕度達90%或溫度達85℃，則將切換單元12切換至非導通狀態，以切斷電池單元11的電力輸出，以維持電池單元11的使用壽命。 The temperature and humidity sensing unit 222 is electrically connected to the control module 21 for sensing the temperature and humidity changes of the battery module 10 and correspondingly generating a temperature and humidity signal, so that the control module 21 switches the switching unit 12 according to the temperature and humidity signal. The state, in turn, controls whether the battery module 11 is powered or not. In other words, the temperature and humidity sensing unit 222 can sense whether there is water immersion in the battery module 10 or whether the placed position is too humid, etc., to avoid the contact or metal contact of the battery unit 11 (not shown) Show) Long-term in a humid environment resulting in metal oxide rust corrosion or leakage. If the control module 21 determines the temperature of the battery module 10 Or the humidity is abnormal, for example, the humidity reaches 90% or the temperature reaches 85 ° C, and the switching unit 12 is switched to the non-conduction state to cut off the power output of the battery unit 11 to maintain the service life of the battery unit 11.

氣體感測單元223電連接於控制模組21，用以感測電池單元11的氣體變化並對應產生一氣味訊號，使得控制模組21根據該氣味訊號切換切換單元12的狀態，進而控制電池模組11供電與否。在本實施例中，氣體感測單元223感測電池模組10的氣體變化主要是偵測電池單元11本體是否有產生漏液，或是電池單元11內部是否有燒毀/燃燒產生焦臭味等，在本實施例中，在電解液漏出前，電池單元11中的氣體會為LiPF(六氟磷酸鋰)，而在電解液漏出後，電池單元11中的氣體會為HF(氫氟酸)及POF3(三氟一氧化磷)。因此，當控制模組21判斷電池模組10的氣體出現異常時，則將切換單元12切換至非導通狀態，以切斷電池單元11的電力輸出。 The gas sensing unit 223 is electrically connected to the control module 21 for sensing the gas change of the battery unit 11 and correspondingly generating an odor signal, so that the control module 21 switches the state of the switching unit 12 according to the odor signal, thereby controlling the battery mode. Group 11 is powered or not. In the embodiment, the gas sensing unit 223 senses the gas change of the battery module 10 mainly by detecting whether the battery unit 11 has a liquid leakage, or whether the battery unit 11 has burnt/burned to generate a burnt smell. In the present embodiment, before the electrolyte leaks, the gas in the battery unit 11 will be LiPF (lithium hexafluorophosphate), and after the electrolyte leaks, the gas in the battery unit 11 will be HF (hydrofluoric acid) and POF3 ( Trifluorophosphorus oxide). Therefore, when the control module 21 determines that the gas of the battery module 10 is abnormal, the switching unit 12 is switched to the non-conduction state to cut off the power output of the battery unit 11.

電力感測單元224電連接於控制模組21，用以感測電池模組10的電壓或電流變化並對應產生一電力訊號，使得控制模組21根據該電力訊號切換切換單元12的狀態，進而控制電池模組11供電與否，以對電池模組10做電壓過低、電壓過高、電流過載、短路偵測等保護。若在電池模組10儲能或釋能的過程中發生電流過大或過充等情況，電力感測單元224會感測出電池模組10的電流異常，進而使控制模組21將切換單元12切換至非導通狀態，以切斷電池單元11的電力輸出。 The power sensing unit 224 is electrically connected to the control module 21 for sensing the voltage or current change of the battery module 10 and correspondingly generating a power signal, so that the control module 21 switches the state of the switching unit 12 according to the power signal, and further The battery module 11 is controlled to supply power or not to protect the battery module 10 from excessive voltage, excessive voltage, current overload, and short circuit detection. If the current is too large or overcharged during the storage or release of the battery module 10, the power sensing unit 224 senses the abnormality of the current of the battery module 10, so that the control module 21 will switch the unit 12. Switching to the non-conduction state cuts off the power output of the battery unit 11.

因此，透過感測模組22感測電池模組10的溫溼度、電流充放電狀態，或是感測是否處於強烈撞擊、傾斜、翻倒、落下、浸水等狀態，並於發生異常情況時，即時切斷電池模組10的電力輸出，使其對外絕緣隔離避免發生短路產生火花發生危險。特別說明的是，本實施例的感測模組22是包括加速度感測單元221、溫濕度感測單元222及氣體感測單元223，以有更多方面的感測內容，當然，感測模組22也可以只包括加速度感測單元221、溫濕度感測單元222及氣體感測單元223其中至少一，同樣能達到本案維持車輛安全的功效，故並不以本實施例為限。 Therefore, the sensing module 22 senses the temperature and humidity of the battery module 10, the current charge and discharge state, or senses whether it is in a state of strong impact, tilt, tipping, falling, water immersion, etc., and when an abnormal situation occurs, The power output of the battery module 10 is immediately cut off to isolate the outer insulation from the occurrence of a short circuit to generate a spark. Specifically, the sensing module 22 of the present embodiment includes an acceleration sensing unit 221, a temperature and humidity sensing unit 222, and a gas sensing unit 223 to have more aspects of sensing content, of course, sensing mode. The group 22 may also include at least one of the acceleration sensing unit 221, the temperature and humidity sensing unit 222, and the gas sensing unit 223, which can also achieve the safety of the vehicle in the present case, and is not limited to the embodiment.

此外，本電池監控及保護裝置20還可包括一電連接於控制模組21的儲存模組23，該儲存模組23可為一記憶體，當控制模組21判斷發生異常情況時，可先將感測模組22的感測結果儲存於儲存模組23中，以便於事後的分析及維修。再者，本電池監控及保護裝置20也可包括一電連接於控制模組21的警示模組24，當異常情況發生時，控制模組21可同步控制警示模組24發出警示訊號，本實施例之警示模組24可為蜂鳴器、車輛中的顯示或燈光設備等，所對應之警示訊號可為聲音訊號、光訊號等，警示模組24還可以為一警示訊號收發器，用以傳送警示訊號至一中繼站或中央控制系統(圖未示)，以告知相關人員。 In addition, the battery monitoring and protection device 20 can further include a storage module 23 electrically connected to the control module 21, and the storage module 23 can be a memory.

步驟S10，加速度感測單元221感測電池模組10的傾 角及加速度變化，並將感測結果傳送至控制模組21。 In step S10, the acceleration sensing unit 221 senses the tilt of the battery module 10 The angle and acceleration change, and the sensing result is transmitted to the control module 21.

步驟S20，溫濕度感測單元222感測電池模組10的溫度與濕度變化，並將感測結果傳送至控制模組21。 In step S20, the temperature and humidity sensing unit 222 senses the temperature and humidity changes of the battery module 10, and transmits the sensing result to the control module 21.

步驟S30，氣體感測單元223感測電池模組10的氣體變化，並將感測結果傳送至控制模組21。 In step S30 , the gas sensing unit 223 senses the gas change of the battery module 10 and transmits the sensing result to the control module 21 .

步驟S40，電力感測單元224感測電池模組10儲能或釋能時的電流變化，並將感測結果傳送至控制模組21。 In step S40, the power sensing unit 224 senses the current change when the battery module 10 is stored or released, and transmits the sensing result to the control module 21.

特別說明的是，上述步驟S10至S40是分別由加速度感測單元221、溫濕度感測單元222、氣體感測單元223及電力感測單元224四個感測單元執行，因此，上述步驟S10至S40的執行順序可以任意對調或是同步執行。此外，上述已說明感測模組22可以只包括加速度感測單元221、溫濕度感測單元222及氣體感測單元223其中至少一，故步驟S10至S40可配合感測模組22中感測單元的數量作對應的增減。 Specifically, the above steps S10 to S40 are performed by the four sensing units of the acceleration sensing unit 221, the temperature and humidity sensing unit 222, the gas sensing unit 223, and the power sensing unit 224, respectively. The execution order of the S40 can be arbitrarily reversed or executed synchronously. In addition, the above-described sensing module 22 can only include at least one of the acceleration sensing unit 221, the temperature and humidity sensing unit 222, and the gas sensing unit 223, so the steps S10 to S40 can be matched with the sensing in the sensing module 22. The number of units is correspondingly increased or decreased.

步驟S50，控制模組21判斷加速度感測單元221、溫濕度感測單元222、氣體感測單元223及電力感測單元224其中之一的感測結果是否達一保護條件，若是，則執行步驟S60；若否，則重複執行步驟S10~S40。上述的保護條件是指該些感測單元的感測結果的安全臨界值，例如：若車輛已傾斜45度角以上，則控制模組21即判定車輛處於傾斜狀態，故加速度感測單元221的感測之傾角若超過45度(即保護條件)，則執行步驟S60，或是加速度感測單元221的感測之加速度若超過4G(即保護條件)，控制模組21即判 定車輛遭受撞擊，故同樣執行步驟S60。 In step S50, the control module 21 determines whether the sensing result of one of the acceleration sensing unit 221, the temperature and humidity sensing unit 222, the gas sensing unit 223, and the power sensing unit 224 reaches a protection condition, and if so, performs the steps. S60; if not, repeat steps S10 to S40. The above-mentioned protection condition refers to a safety threshold value of the sensing result of the sensing units. For example, if the vehicle has been tilted by more than 45 degrees, the control module 21 determines that the vehicle is in an inclined state, so the acceleration sensing unit 221 If the inclination of the sensing exceeds 45 degrees (ie, the protection condition), step S60 is performed, or if the sensed acceleration of the acceleration sensing unit 221 exceeds 4G (ie, the protection condition), the control module 21 determines The vehicle is subjected to an impact, so step S60 is also performed.

步驟S60，控制模組21控制切換單元12切換至非導通狀態，以切斷電池單元11的電力輸出，並同時控制警示模組24發出警示。電池監控及保護裝置20若包括儲存模組23，則控制模組21會先各感測單元的感測結果儲存於儲存模組23中，才控制切換單元12切換至非導通狀態。 In step S60, the control module 21 controls the switching unit 12 to switch to the non-conduction state to cut off the power output of the battery unit 11, and simultaneously controls the warning module 24 to issue an alarm. If the battery monitoring and protection device 20 includes the storage module 23, the control module 21 stores the sensing results of the sensing units in the storage module 23 before controlling the switching unit 12 to switch to the non-conduction state.

綜上所述，本電池監控及保護系統100藉由電池監控及保護裝置20中的感測模組22感測電池模組10的各種狀態，例如：溫溼度、電壓、電流、電池容量計算、短路偵測、是否處於強烈撞擊、傾斜、翻倒、落下、浸水等，並於發生異常情況時，即時切斷電池模組10的電力輸出，使得本電池監控及保護系統100更趨向於安全、穩定、可靠，故確實能達成本發明之目的。 In summary, the battery monitoring and protection system 100 senses various states of the battery module 10 by the sensing module 22 in the battery monitoring and protection device 20, such as temperature, humidity, voltage, current, battery capacity calculation, Short-circuit detection, whether it is in strong impact, tilt, tipping, falling, water immersion, etc., and when the abnormal situation occurs, the power output of the battery module 10 is immediately cut off, so that the battery monitoring and protection system 100 tends to be safer. It is stable and reliable, so it can achieve the object of the present invention.

惟以上所述者，僅為本發明之較佳實施例而已，當不能以此限定本發明實施之範圍，即大凡依本發明申請專利範圍及發明說明內容所作之簡單的等效變化與修飾，皆仍屬本發明專利涵蓋之範圍內。 The above is only the preferred embodiment of the present invention, and the scope of the invention is not limited thereto, that is, the simple equivalent changes and modifications made by the scope of the invention and the description of the invention are All remain within the scope of the invention patent.
