Smart meter
Apr. 22, 2024
As a new technology in the field of Internet of Things and the future development direction, NB-IoT, with its wide coverage, large connection, low efficiency, high security and other technical characteristics, has brought better technical solutions and more abundant application scenarios for the construction of smart gas. The smart gas meter is the second meter product in NB-IoT applications that has reached a million applications in addition to the smart water meter. It is a general trend for NB-IOT smart gas meters to replace traditional membrane gas meters. For users using iot gas meters, the data can be quickly queried and summarized.
SUNJ's ER26500H and ER34615H batteries, their energy density is about 4 times that of alkaline batteries, a single battery voltage can reach 3.6V, can easily withstand 100mA pulse current; In addition, the single battery capacity is large, and the annual self-discharge rate is less than 1% at normal temperature, which is the most suitable gas meter power supply.Lora NB-IOT intelligent remote water meter we recommend SUNJ lithium thionyl chloride （LiSoCl2）capacity battery + super capacitor scheme, er26500h + epc1520, which mainly has the following advantages:
Compared with power battery er26500m and lithium manganese（LiMnO2） battery CR26500, the safety and reliability are greatly improved, and the maintenance free time is greatly prolonged;
The super capacitor epc1520 can discharge with high pulse current when communication needs or mechanical action, up to 2A current;
This scheme can fully use the capacity of the battery and prolong the service life of the LiSoCl2 battery er26500h;
It can broaden the working temperature range of the system - 55 to 85 ℃;
The voltage delay of LiSoCl2Lisocl2 battery can be avoided.
Er14250 lithium battery, Li-SOCL2, with rated voltage of 3.6V and rated capacity of 1200mAh, is mainly used as the supporting power supply for functions such as timely clock (RTC) power failure display and data collection and transmission in smart meters. It is the core component of smart electricity meters.
