技术领域technical field
本发明涉及电池状态监测及校准技术领域，特别是涉及一种备用电池供电电路、备用电池的电池状态监测及校准方法。The invention relates to the technical field of battery state monitoring and calibration, in particular to a backup battery power supply circuit and a battery state monitoring and calibration method for the backup battery.
背景技术Background technique
在存储产品设计中，若使用到BBU(Backup Battery Unit，备用电池模块)，由于系统设计需求，系统通常需隔几天要做电池状态监测来检查BBU的放电能力，另外还需要每隔一定时间为BBU做校准检查BBU的电化学特性。In storage product design, if a BBU (Backup Battery Unit, backup battery module) is used, due to system design requirements, the system usually needs to monitor the battery status every few days to check the discharge capacity of the BBU. Calibrate the BBU to check the electrochemical properties of the BBU.
现有存储产品设计中BBU的设计方法是BBU与PSU(Power Supply Unit电源供应器模块)电路或门设计，当需要执行BBU电池状态监测时，关闭PSU输入开启BBU输入，执行BBU监测；当需要执行BBU自放电校准时，通过开启BBU内部放电电路来完成。具体的，现有BBU应用设计方案如图1所示：在做BBU检测工作状态时，关闭选通电路10的通路1，打开通路2，BBU在此状态下为存储整机系统11和风扇12供电，BBU的输出功率等于存储整机系统11和风扇12的总功率，如果存储整机系统配置高，此时BBU就存在发生过流的风险；执行BBU校准时，PSU正常供电，开启BBU内部放电电路来实现BBU校准。The BBU design method in the existing storage product design is BBU and PSU (Power Supply Unit power supply module) circuit or gate design. When it is necessary to perform BBU battery status monitoring, turn off the PSU input and turn on the BBU input to perform BBU monitoring; When performing BBU self-discharge calibration, it is completed by turning on the BBU internal discharge circuit. Specifically, the existing BBU application design scheme is shown in Figure 1: when the BBU is detecting the working state, the channel 1 of the gating circuit 10 is closed, and the channel 2 is opened. In this state, the BBU is the storage system 11 and the fan 12 For power supply, the output power of the BBU is equal to the total power of the storage system 11 and the fan 12. If the configuration of the storage system is high, there is a risk of overcurrent in the BBU at this time; discharge circuit to achieve BBU calibration.
现有设计方案中，BBU是按照正常备电流程进行设计，执行BBU检测时，存储整机系统当前工作状态与PSU供电时保持一致，存储整机系统所需功率值有可能超过BBU所能提供的最大值，如出现此状态BBU会发生过流保护造成存储整机掉电；在执行BBU校准时，通过开启BBU内部放电电路来实现，BBU内部放电功率只有5瓦左右，而BBU的容量一般都在30瓦，电芯并联的BBU容量都有几十瓦，因此校准的时间比较长。In the existing design scheme, the BBU is designed according to the normal power backup process. When the BBU detection is performed, the current working status of the storage system is consistent with that of the PSU, and the power required by the storage system may exceed what the BBU can provide. If this state occurs, the BBU will be over-current protected and the whole storage machine will be powered off; when performing BBU calibration, it is realized by turning on the internal discharge circuit of the BBU. The internal discharge power of the BBU is only about 5 watts, and the capacity of the BBU is generally They are all at 30 watts, and the capacity of the BBU with cells connected in parallel is tens of watts, so the calibration time is relatively long.
