Application of energy storage 21700 battery in POS machines

Application of energy storage lithium-ion 21700 battery in POS machines. Energy storage lithium-ion 21700 battery are suitable for fixed POS machines and non-POS machines used by large and medium-sized supermarkets, chain stores, hypermarkets, large and medium-sized restaurants and all high-level management retail companies. The design method of energy storage lithium-ion 21700 battery is very flexible to meet the personalized, diversified and international chemical power supply needs of industrial users.

Application of energy storage lithium-ion 21700 battery in POS machines

The advantage of mobile POS machines is that they can be used anytime and anywhere without being restricted by scenarios. The energy storage lithium-ion battery used in general financial POS machines is composed of two 103450 lithium-ion batteries connected in series and encapsulated in a plastic shell to form a 7.4V energy storage lithium-ion battery pack.

According to customer requirements and specifications, a POS machine energy storage lithium-ion battery pack is designed to match the host, and the intelligent power meter with communication protocol, lithium-ion battery and safety protection performance are integrated into the solution to realize information sharing between the energy storage lithium-ion battery pack and the POS host. At the same time, in order to ensure the safety and stability of the energy storage lithium-ion battery pack, multiple layers of protection must be taken inside the battery pack to prevent damage to the energy storage lithium-ion battery due to overcharging, over-discharging or short circuit.

There are certain conditions for the service life of POS lithium-ion batteries. We must consider the storage conditions of industrial POS lithium-ion batteries.

Charge: 50%~60%, humidity range: 60±15%R.H

Storage temperature: less than one month: -20~60℃

Less than 6 months: -20~30℃

POS lithium-ion batteries are the power source of wireless POS machines, and the 7.4V lithium-ion battery pack can just meet the working voltage requirements of this series of POS machines. Lithium-ion batteries have many advantages such as high single-cell voltage, high specific energy, small size, long life, and no memory effect. Their application in industrial POS machines has been expanding year by year, truly realizing the wireless operation of industrial POS machines, free payment locations and small size.

Features of POS Lithium-ion Battery Pack

1>Imported lithium-ion battery cell: Two Panasonic 103450 lithium-ion battery cells are connected in series to form a lithium-ion battery pack with a nominal voltage of 7.4V.

2>Accurate power display: The intelligent power meter IC with communication protocol is integrated into the solution. The intelligent power meter can accurately calculate the remaining battery power and the remaining operating time, and transmit the calculated results to the host in real time, so that the host can better grasp the information of the POS lithium-ion battery.

3>Secondary protection: The automatic recovery PTC can prevent the high-temperature discharge and unsafe high current of the 7.4V lithium-ion battery pack.

4>Lithium-ion battery safety protection: The basic protection circuit of lithium-ion battery can prevent the occurrence of battery overcharge, over-discharge, overcurrent and short circuit, so that the battery can operate more safely and stably.

5>Metal contact output: Seamless combination with the host, better use of space, and make the product more upscale.

6>Light and beautiful plastic shell packaging: The fire protection level of the plastic shell can reach UL-94V0.

The intelligent lithium-ion battery pack for POS machines matched with the host integrates the intelligent power meter with communication protocol, lithium-ion battery and safety protection performance into the solution, which can achieve information sharing between the intelligent lithium-ion battery pack and the POS host, and finally realize a reasonable, efficient and safe battery management method.
