First, in step S310, at least one battery (for example, the first battery 113) of the battery storage device is provided. Then, in step S320, the connection status with a first network and the power supply status of an external power supply are detected. Specifically, the battery storage device can detect the connection status with the first network through the network connection unit and can detect the power supply status of the external power supply of the corresponding battery storage device through the power detection unit. When the network connection unit is connected to the first network, it is in a connection state, and when the network connection unit is not connected to the first network, it is in an offline state. Similarly, when the external power supply has enough power to supply the battery storage device, the power supply state of the external power supply is the power supply state. Conversely, when the external power supply does not have enough power to supply the battery storage device
When the device is stored or the power supply to the battery storage device is stopped, the power supply state of the external power supply is no power supply or low power state. In some embodiments, the
在一些實施例中,電池儲存裝置可透過電量偵測單元偵測並取得每一電池之一目前電量。在此實施例中,電池係指電池儲存裝置中可供使用的電池。值得注意的是,在一些實施例中,電量偵測單元可具有偵測電路或其他電量偵測的軟硬體元件,用以對各電池進行電量偵測,產生相應電池的電量資料。在一實施例中,相應電池的電量資料係用以表示電池的目前電量。當取得所有電池的目前電量之後,電池儲存裝置依據所有電池之目前電量,決定要用來供電給電池儲存裝置的供電電池位置及電池數量,其中選取的供電電池之剩餘電量高於一既定電量。在一些實施例中,既定電量可定義為高於百分之八十的電量,但不限於此。提醒的是,既定電量的數值可根據實際使用環境與策略進行調整。在一實施例中,電池儲存裝置可以先從所有第二電池中找出符合電量高於既定電量的需求的一或多顆候選電池,再由候選電池中選出一者作為供電電池。在一實施例中,供電電池係為候選電池中電量最高之一者。在另一實施例中,供電電池係為候選電池中電量最低之一者。在又一實施例中,供電電池係為候選電池中隨機選取之一者,但本發明並不限於此。 In some embodiments, the battery storage device can detect and obtain a current power level of each battery through the power detection unit. In this embodiment, the battery refers to the battery available for use in the battery storage device. It is worth noting that, in some embodiments, the power detection unit may have a detection circuit or other power detection software and hardware components to perform power detection on each battery to generate power data of the corresponding battery. In one embodiment, the power data of the corresponding battery is used to indicate the current power of the battery. After obtaining the current power of all batteries, the battery storage device determines the location and number of power supply batteries to be used to power the battery storage device according to the current power of all batteries, wherein the remaining power of the selected power supply battery is higher than a predetermined power. In some embodiments, the predetermined power amount may be defined as a power amount higher than 80%, but is not limited thereto. It is reminded that the value of the established power can be adjusted according to the actual use environment and strategy. In an embodiment, the battery storage device may first find out one or more candidate batteries that meet the requirement of a power higher than the predetermined power from all the second batteries, and then select one of the candidate batteries as the power supply battery. In one embodiment, the power supply battery is the one with the highest power among the candidate batteries. In another embodiment, the power supply battery is the one with the lowest power among the candidate batteries. In another embodiment, the power supply battery is one of the candidate batteries randomly selected, but the invention is not limited to this.
第4圖顯示依據本發明另一實施例之電動車之電池管理方法。依據本發明實施例之電動車之電池管理方法適用於一電池管理系統,如第1、2圖中之電池管理系統100且由電池儲存裝置110中的控制器118所執行。舉例來說,在一實施例中,電池儲存裝置110可為具有多個電池
插槽且其有充電及/或電池交換功能的充電站,允許電動車的使用者可將其電動車的電池插入其中一電池插槽中進行充電或者可將其電動車的電池插入其中以與電池插槽上的一電池進行一電池交換服務,但不限於此。在此實施例中,假設電池儲存裝置110連接一外部電源(例如:市電)以對第一電池113進行充電。
Figure 4 shows a battery management method for an electric vehicle according to another embodiment of the present invention. The battery management method for an electric vehicle according to the embodiment of the present invention is applicable to a battery management system, such as the
首先,如步驟S410,透過電量偵測單元,持續偵測相應電池儲存裝置之外部電源之供電狀態。當相應電池儲存裝置之供電狀態變為一供電狀態時,如步驟S420,停止透過至少一電池輸出電力至電池儲存裝置並由電池儲存裝置輸出電力至至少一電池。 First, in step S410, the power detection unit continuously detects the power supply status of the external power supply of the corresponding battery storage device. When the power supply state of the corresponding battery storage device becomes a power supply state, in step S420, stop outputting power to the battery storage device through the at least one battery and output power from the battery storage device to the at least one battery.
在一些實施例中,相應於偵測到與第一網路為離線狀態且外部電源之供電狀態為未供電或低電量狀態時,電池儲存裝置可透過第一網路以外的一第二網路例如無線網路或藍芽網路或4G網路等傳送一提醒訊息至一特定標的,其中特定標的可以是相應電池儲存裝置的管理人員或維修人員。上述提醒訊息可以是簡短訊息,用以告知相應電池儲存裝置的管理人員或維修人員關於電池儲存裝置的供電已停止,需盡快派人處理。藉此,電池儲存裝置仍可以在外部電源停止供電之後維持一段時間的運作,使得管理人員或維修人員在接收到提醒訊息後,有更多的時間能夠在電池儲存裝置完全停止運作之前前往處理,增加危機處理能力。 In some embodiments, when it is detected that the first network is offline and the power supply state of the external power supply is unpowered or low power state, the battery storage device can pass through a second network other than the first network For example, a wireless network or a Bluetooth network or a 4G network sends a reminder message to a specific target, where the specific target can be the management or maintenance personnel of the corresponding battery storage device. The above-mentioned reminder message can be a short message to inform the management or maintenance personnel of the corresponding battery storage device that the power supply of the battery storage device has been stopped, and someone needs to be dispatched to deal with it as soon as possible. In this way, the battery storage device can still operate for a period of time after the external power supply is stopped, so that after receiving the reminder message, the management or maintenance personnel have more time to process before the battery storage device completely stops functioning. Increase crisis management capabilities.
在一些實施例中,相應於偵測到與第一網路為離線狀態且外部電源之供電狀態為未供電或低電量,可以致使電池儲存裝置進入一功能限用模式,其中,在功能限用模式中,僅允許電池儲存裝置執行一特定必要操作並禁止電池儲存裝置執行其他操作。在一些實施例中,其中特定必要操作係為一顯示操作,例如只顯示電源即將用完的提示或只提供必要顯示的電力,而不允許進行電池充換電或關閉其他地方的電力,藉此可節省不必要的電力消耗。 In some embodiments, corresponding to the detection that the first network is offline and the power supply state of the external power supply is unpowered or low power, the battery storage device may enter a function-restricted mode. In the mode, the battery storage device is only allowed to perform a specific necessary operation and the battery storage device is prohibited from performing other operations. In some embodiments, the specific necessary operation is a display operation, such as displaying only a prompt that the power is about to run out or providing only necessary display power, and not allowing battery charging or switching off or shutting down the power in other places, thereby Can save unnecessary power consumption.
在一些實施例中,電池儲存裝置可更包括一備用電源(例如:一不斷電系統(UPS)),當電池儲存裝置偵測到與第一網路為離線狀態且相應電池儲存裝置之供電狀態為未供電狀態時,電池儲存裝置先透過備用電源供電至電池儲存裝置。接著,電池儲存裝置持續偵測相應備用電源之一供電狀態。當相應備用電源之供電狀態為未供電或低電量狀態時,透過 至少一電池輸出電力至電池儲存裝置。也就是說,在此實施例中,當電池儲存裝置內建有備用電源時,會先使用備用電源進行電力供給,一旦備用電源的電力快用完了,便可透過至少一電池輸出電力至電池儲存裝置,從而可以延長電池儲存裝置的有效使用時間。 In some embodiments, the battery storage device may further include a backup power source (for example: an uninterrupted power system (UPS)), when the battery storage device detects that the first network is offline and the corresponding battery storage device is powered When the state is not powered, the battery storage device first supplies power to the battery storage device through a backup power source. Then, the battery storage device continuously detects the power supply state of one of the corresponding backup power sources. When the power supply status of the corresponding backup power supply is no power supply or low power status, through At least one battery outputs power to the battery storage device. That is to say, in this embodiment, when the battery storage device has a built-in backup power supply, the backup power supply will be used for power supply first. Once the power of the backup power supply is almost used up, it can output power to the battery storage through at least one battery Device, which can extend the effective use time of the battery storage device.
在一些實施例中,電池儲存裝置在透過至少一電池輸出電力之後,可持續透過網路連接單元偵測與第一網路之連線狀態且當偵測到與第一網路為一連線狀態時(亦即:網路連線恢復時),可以透過第一網路傳送一電力不足通知至一伺服器。伺服器於透過第一網路接收到電力不足通知後可發送通知給相關人員進行故障排除或後續處理,以免電池儲存裝置因電力不足或電力中斷而造成長時間無法使用。在一些實施例中,電池儲存裝置在透過至少一電池輸出電力之後,電池儲存裝置持續偵測相應電池儲存裝置之供電狀態且當相應電池儲存裝置之供電狀態變為一供電狀態時(亦即:供電恢復時),停止透過至少一電池輸出電力至電池儲存裝置並輸出電力至至少一電池。 In some embodiments, after the battery storage device outputs power through at least one battery, it can continuously detect the connection status with the first network through the network connection unit and when it detects that it is a connection with the first network In the state (that is, when the network connection is restored), a power shortage notification can be sent to a server through the first network. After the server receives the power shortage notification through the first network, it can send a notification to the relevant personnel for troubleshooting or subsequent processing, so as to prevent the battery storage device from being unavailable for a long time due to insufficient power or power interruption. In some embodiments, after the battery storage device outputs power through at least one battery, the battery storage device continuously detects the power supply state of the corresponding battery storage device and when the power supply state of the corresponding battery storage device becomes a power supply state (ie: When power supply is restored), stop outputting power to the battery storage device through at least one battery and output power to at least one battery.
以下舉一例子進行說明,然而可理解的是,本發明並未限定於此。在此實施例中,外部電源(例如:市電)供應電池儲存裝置所需的電力且電池儲存裝置透過一第一網路連線至一伺服器,以對電池儲存裝置的插槽中的所有電池進行充電。當發生停電時,外部電源的供電將會停止或中斷且網路連線也會中斷,電池儲存裝置將會偵測到相應電池儲存裝置的外部電源之供電狀態為未供電或低電量且電池儲存裝置與第一網路為一離線狀態,因此便根據電池儲存裝置的電池的剩餘電量與相應電池儲存裝置的電量需求,使電池放電,透過一或多個電池輸出足夠的電力至電池儲存裝置以維持電池儲存裝置的正常運作。此時,可以根據實際需求,限制部分的功能,以延長電池儲存裝置的使用時間。之後,當電力恢復之後,外部電源的供電將會恢復且網路也會重新連線,電池儲存裝置將會偵測到相應電池儲存裝置的外部電源之供電狀態變為供電狀態且電池儲存裝置與第一網路變為連線狀態,因此電池儲存裝置便停止透過至少一電池輸出電力。在一些實施例中,電池儲存裝置可以將這些用來作為緊急電源的電池重新進行充電。 The following is an example for description, but it is understandable that the present invention is not limited thereto. In this embodiment, an external power source (e.g., utility power) supplies the power required by the battery storage device and the battery storage device is connected to a server through a first network, so that all batteries in the slot of the battery storage device Charge it. When a power failure occurs, the external power supply will be stopped or interrupted and the network connection will also be interrupted. The battery storage device will detect that the external power supply status of the corresponding battery storage device is not powered or low and the battery is stored The device and the first network are in an offline state, so according to the remaining battery power of the battery storage device and the power demand of the corresponding battery storage device, the battery is discharged, and sufficient power is output to the battery storage device through one or more batteries. Maintain the normal operation of the battery storage device. At this time, some functions can be restricted according to actual needs to extend the use time of the battery storage device. Later, when the power is restored, the external power supply will be restored and the network will be reconnected. The battery storage device will detect that the external power supply state of the corresponding battery storage device has changed to the power supply state and the battery storage device The first network becomes connected, so the battery storage device stops outputting power through at least one battery. In some embodiments, the battery storage device can recharge these batteries used as emergency power sources.
