Battery chargers are devices specifically designed to charge lithium batteries and lead acid batteries. Siricinko launched a 60V/6A high-power intelligent charger solution, with its self-developed SK88F064 series high-performance charging management chip as the core and using a single-chip high-precision architecture to solve the root causes of battery bulge, shrinking battery life, and unsafe charging., etc., greatly reducing the after-sales pressure of manufacturers.

In order to further improve customers 'production efficiency, Siruxinco has specially developed mass production tools. Abandoning the traditional inefficient calibration method of manual resistor adjustment, one-click automatic calibration only takes 10 seconds. The constant voltage error can be controlled within 0.5%, and the constant current error can be controlled within 1%. The accuracy of each product is uniform, greatly saving mass production labor and time costs. At the same time, in order to make it easier to configure various calibration parameters, a web version of host computer software is provided to facilitate users to quickly adjust various parameters.

The above is a schematic diagram of the full-process charging curve of a lead-acid battery. There are four processes: trickle charging, constant current charging, constant voltage charging, and floating voltage charging. Lithium batteries have three stages: trickle charging, constant current charging, and constant voltage charging. Taking lithium battery charging as an example, the whole process is as follows: Trickle charging: When SK88F064 detects that the battery voltage is lower than Vt, reduce the charging current and control the charging current within the trickle charging current range. Restores battery activity. Constant current charging: As the charging time increases, the battery voltage gradually increases. When it reaches Vt, the charging current changes to constant current charging. That is, the battery is charged with a constant high current to speed up the charging speed. Constant voltage charging: When the battery voltage reaches Vc, it switches to constant voltage mode, that is, charging at constant voltage. The charging current gradually decreases. Charging termination: When SK88F064 detects that the charging current is less than Iu, it considers the battery to be fully charged and stops charging.
