The component of charging control chip
It is used to control current, voltage, power and other parameters during charging to ensure charging efficiency and safety. At the same time, it can realize the dynamic adjustment of charging speed and time, and provide protection functions, such as overload protection, short circuit protection, over temperature protection, etc.
Main component
Configure charging current through external resistor, such as in SUM4056 chip, charging current formula is: IBAT = 1000 / RIREF.
Support dual lights to indicate charging status, such as SUM4056 chip, red light is used to indicate charging status, green light is used to indicate full status.
integrated battery temperature NTC detection and protection, such as SUM4056 chip support battery temperature NTC detection.
used to control the compromise between chip temperature and charging current, effectively protect the chip from overheating damage.
Integrated LED indicates charging status to ensure stable brightness of indicator light.
Integrated trickle, constant current and constant voltage three-stage linear charging management, in line with lithium battery charging specifications.
For chip enabled control, such as the EN of SUM4056 for chip enabled control.
built-in anti-backflow circuit, such as SUM4056 integrated anti-backflow circuit, automatically cut off the current path of the battery backflow chip after the input voltage is pulled out or short circuit.
Provides the battery overvoltage protection function to prevent the battery from overcharging.
Integrated chip overheating protection to protect the chip from high temperature damage.
Integrated battery unconnected detection, such as SUM4156 chip when not connected two indicator lights alternately flashing.
DC CHARGING PIlE SERIES
DC charging pile is an efficient charging facility for electric vehicles, which uses direct current (DC) to directly charge the vehicle battery, significantly reducing the charging time. Compared with traditional AC charging piles, DC charging piles are able to provide higher power output and can usually charge an EV to 80% of its capacity in 30 minutes, providing users with a convenient charging experience.
