The page is about POS terminal battery information. They include POS machine, POS terminal, handheld POS machine, POS machine with printer, cash POS machine, billing POS machine, payment terminal.

POS machine battery

Design scheme of intelligent battery based on POS machine

  • According to the customer’s requirements and specifications, design the intelligent battery pack matched with the host, and integrate the intelligent fuel gauge with communication protocol and battery safety protection into your solution, which can achieve the information sharing between the battery pack and the host, and finally achieve a reasonable , Efficient and safe battery management solutions.

  • In the design process of the whole scheme, the direction of achieving the most perfect integration with the host is to ensure the safety of the battery, the battery pack and the entire system, and the first consideration is to meet the corresponding design regulations and certification regulations. In recent years, due to the rapid development of lithium batteries, many portable products use the voltage measurement value to estimate the remaining battery capacity, but the relationship between the battery voltage and the remaining battery capacity will change with the discharge rate, temperature and battery aging. The error rate of the method can be up to 50%.

  • Due to the increasing market demand for products that last longer, more precise solutions are required when designing. Using a fuel gauge IC to measure the charge or drain of the battery will provide a more precise estimate of battery charge over a wide range of application power levels. At the same time, in order to ensure the safety and reliability of the lithium battery, multiple layers of protection must be adopted inside the battery pack to prevent the lithium battery from being damaged by overcharge, overdischarge or short circuit.
POS Terminal
  1. Protection Board (PCM): It is mainly a protection circuit designed for rechargeable battery packs (generally refers to lithium batteries). Due to the chemical characteristics of lithium batteries, it is necessary to provide overcharge, overdischarge, short circuit, overcurrent, etc. and overtemperature, etc. Protective function. In order to avoid the danger of burning and explosion.

  2. Protection IC: The main protection function chip of the design scheme, which performs online monitoring of overcharge, over-discharge, overcurrent, short current and other functions of the cell. Make the cells work in a safe, stable and efficient range.

  3. Overcurrent Protection Sheet (PTC): Mainly designed for secondary protection function. The PTC resettable fuse has the dual function of overcurrent protection and automatic recovery. PTC in battery products can prevent high temperature discharge of batteries and the occurrence of unsafe high currents.

  4. Battery model: 18650 2S1P battery pack, or 103450-3.7V-1800mAh.

  5. Field-effect transistor (MOSFET): MOSFET plays a switching role in the protection circuit, so that the voltage across the load will never increase or decrease, ensuring voltage stability.

What is the reason why the POS machine cannot be charged?

  1. The battery level display may be a problem caused by a malfunctioning POS system. This problem is the easiest to solve. You can directly shut down and restart, which is equivalent to refreshing the data, and the total power display will return to normal.

  2. There is a problem with the charger. This fault is the main reason why the POS machine cannot be charged. So how to judge the quality of the charger?
    It’s actually very simple, just try a different charger. If the charger can be charged, it can be determined that the charger is broken.

  3. The charger is in poor contact with the POS machine. It’s also very common because the POS user is not careful and the charger doesn’t get plugged in. The fix is simple: replace the socket back and forth.

  4. There is a problem with the POS battery. Lithium batteries should be checked when faulty chargers and POS systems are found. If the battery is found to be bulging, it means that the battery is defective and needs to be replaced.

  5. The POS machine itself has quality problems. Need to return to the factory for repair.
