Lead and plug type: customized according to customer requirementTwo, 14.8V intelligent battery design:
1, the protection board ( PCM ): mainly for rechargeable smart battery protection circuit design, because lithium battery chemical characteristics itself, need to provide intelligent power calculation, overcharge, overdischarge, short circuit, over-current and over-temperature protection function. In order to avoid burning, explosion hazard.
In 2, IC ( Protection IC ): protection of design scheme of the main protection function for electric core chip, overcharge, overdischarge, over current, short circuit and other functions of the online real time monitor. That the electric core in the safe stable and efficient range.
3, overcurrent protection film ( PTC ) : mainly two protection function design. PTC recoverable fuse with overcurrent protection, automatic recovery function. Battery products in the PTC can prevent the battery discharge and unsafe current occurrence.
4, 18650 lithium ion batteries
In 5, the field effect tube ( MOSFET ): MOSFET tube, the protection circuit with switch function, will make the voltage across the load will not increase nor decrease, ensure the voltage stability.
6, power management control chip ( BQ26500 ): the functional integrity of the electricity meter, with a measurement of voltage and temperature of the analog-to-digital converter ( ADC ) and a measuring current and charge sensing module converter. Electricity meter having a microprocessor, is responsible for the implementation of electricity meter, can provide the remaining state of charge ( Remaining State of Capacity ) and other information, BQ26500 products also provide the remaining run time ( Run Time to Empty ). The host may at any time to the electricity meter query the information, information to inform the user of the battery. Electricity meter is very convenient to use. Allowing users to grasp the battery power.
