背景技术Background technique
参见图1，图1是现有技术的智能锁设备中锂电池的供电示意图。目前现有的智能车锁方案大部分采用的是3.6V的一次性锂电池进行供电，锂电池与MCU(微控制单元)控制芯片处于直接连接状态，由锂电池直接给MCU进行供电，驱动MCU的正常工作，从而控制其他的电路系统模块进行工作。同时，由于GSM/GPS(全球移动通讯系统/全球定位系统)模块的电压需求为3.8～4V，锂电池还要通过DC-DC(直流-直流)升压转换芯片进行升压转换，从而为GSM/GPS模块进行供电，驱动其正常工作。Referring to FIG. 1 , FIG. 1 is a schematic diagram of a lithium battery power supply in a smart lock device in the prior art. At present, most of the existing smart car lock solutions use a 3.6V disposable lithium battery for power supply. The lithium battery is directly connected to the MCU (micro control unit) control chip, and the lithium battery directly supplies power to the MCU to drive the MCU. normal work, thereby controlling other circuit system modules to work. At the same time, since the voltage requirement of the GSM/GPS (Global Mobile Communication System/Global Positioning System) module is 3.8 ~ 4V, the lithium battery also needs to be boosted by a DC-DC (direct current-direct current) boost conversion chip to provide a high voltage for GSM. /GPS module for power supply to drive it to work normally.
但是，由于锂电池为一次性供电电池，在锂电池电能不断消耗的情况下，锂电池的内阻增大，锂电池的电压会逐渐下降，而MCU的正常供电电压范围一般为2V～3.6V，通常供电电压为3.3V电压，DC-DC升压转换芯片的输入电压一般为0.7V～5V，因此当锂电池的电压下降到无法支持MCU正常工作(大约2V左右)的时候，此时需要重新更换电池，很容易造成电池的浪费，无法高效地利用电池的电能。同时，由于3.6V接近MCU的最高供电电压的临界值，故如果电池电压不稳定，也很容易造成系统运行的不稳定性，从而增加企业的维修成本。However, since the lithium battery is a one-time power supply battery, the internal resistance of the lithium battery will increase and the voltage of the lithium battery will gradually decrease when the power of the lithium battery is continuously consumed, and the normal power supply voltage range of the MCU is generally 2V ~ 3.6V , usually the power supply voltage is 3.3V, and the input voltage of the DC-DC boost conversion chip is generally 0.7V~5V. Therefore, when the voltage of the lithium battery drops to the point where it cannot support the normal operation of the MCU (about 2V), it is necessary to Re-changing the battery is easy to cause waste of the battery, and the electric energy of the battery cannot be efficiently utilized. At the same time, since 3.6V is close to the critical value of the maximum power supply voltage of the MCU, if the battery voltage is unstable, it is easy to cause the instability of the system operation, thereby increasing the maintenance cost of the enterprise.
