POS Machine Battery

Custom processing: Brand: SANYO / Sanyo Model: 103450AR rated capacity: 1900 (mah) Standard voltage: 7.4 (V) charge current: 1 (A) Dimensions: 100 * 34 * 50 (mm) application types: bank POS Product Certification: CCC applied models: iData MC80 First, the design requirements: according to customer requirements and specifications, design and a host of supporting intelligent battery pack that will take communication protocol intelligent power meter and battery safety protection features integrated into POS machine to solve program to go, lithium batteries can be achieved with the host information sharing, and ultimately to achieve a reasonable, efficient, and safe battery management solutions. In the design process of the entire program in order to achieve the perfect integration with the host as a direction to make sure the lithium battery, the battery pack and the safety of the entire system as a prerequisite to meet the appropriate regulations and certification regulations for the design of choice for consideration. Meanwhile, in order to ensure the safety and reliability of lithium batteries, the internal battery should take a multi-layer protection to prevent the lithium battery overcharge, over discharge or short circuit is destroyed. Second, the design: 1) the protective plate (PCM): mainly for rechargeable battery pack (usually lithium battery) protection circuit design, due to the chemical characteristics of lithium batteries themselves need to provide overcharge, over discharge, short circuit, overcurrent and overtemperature protection. In order to avoid burning and explosion caused. 2) protection IC (Protection IC): The main protection chip design of batteries overcharge, over discharge, online constantly monitor overcurrent, short flow and other functions. Make batteries working in a safe, stable and efficient range. 3) overcurrent protection films (PTC): designed mainly for secondary protection functions. PTC recoverable fuse over-current protection, automatic recovery dual function. Where PTC battery products can prevent battery discharge temperature and the occurrence of large current insecurity. 4) 103450 Sanyo lithium batteries / 103450 Li-ion cell (SANYO). 5) field effect transistor (MOSFET): MOSFET tube, acts as a switch in the protection circuit, the voltage across the load is always not increase nor decrease ensure voltage stability. 6) The power management controller chip (BQ26500): Full-featured power detection meter having a measuring voltage and temperature analog to digital converter (ADC) and a measured current and charge sensing ADC. Power detection meter has a microprocessor, responsible for implementing the power detection meter to provide the remaining battery status (Remaining State of Capacity) and other information, bq26500 products also provide the remaining run time (Run Time to Empty). The host can always check this information to gauge battery detection, battery information will inform the user. Use a battery gauge is very easy to detect. Allowing users to keep abreast of the battery power. 7) Lithium battery package (plastic shell). 8) design schematics:
