Product Details

Hlcbattery has been producing 18650 li ion battery cell packs since 2014. We cooperate with LG, Samsung and Chinese cell factory with excellent BMS into battery pack. All are trying to meet customer demands.

According to the customer’s requirements and specifications, design the POS machine intelligent battery pack matched with the host, and integrate the intelligent fuel gauge with communication protocol, lithium battery and safety protection performance into the solution, which can reach the intelligent lithium battery pack and the POS machine host. Information sharing, and finally realize a reasonable, efficient and safe battery management solution.

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. 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 due to overcharge, overdischarge or short circuit.

Intelligent battery design scheme:

Protection board (PCM): It is mainly a protection circuit designed for rechargeable intelligent battery packs. Due to the chemical characteristics of lithium batteries, it is necessary to provide intelligent power calculation, overcharge, overdischarge, short circuit, overcurrent and overtemperature protection functions. . To avoid fire, explosion and other hazards.

Protection IC (Protection IC): The main protection function chip of the design scheme, which performs online monitoring of overcharge, overdischarge, overcurrent, short circuit and other functions of the cell. Make the cells work in a safe, stable and efficient range.

Overcurrent Protection Sheet (PTC): Mainly designed for secondary protection function. PTC resettable fuse with overcurrent protection, automatic recovery dual function. The PTC in the battery product can prevent the high temperature discharge of the battery and the occurrence of unsafe high current.

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.
