Battery charging interface
The WISMO Quik Q24x6 Series module supports one battery charging circuit
for Li-Ion batteries. This circuit uses an interface which consists of a current
source inputs (CHG_IN) where the constant current has to flow in order to
charge the battery. This current value depends on the battery capacity. It is
recommended to provide a current equal to the value of the capacity plus
50mA. For a 550mA battery the current will be 600mA. The maximum current
is 800mA.
A specific AT command (AT+WBCM), available from 4.3 level, allows to
manage the charge battery (start and stop the charge, enable or disable
unsolicited Battery Charge Indications and set the battery charge parameters).
The WISMO Quik Q24x6 Series module monitors the battery voltage to detect
the end of the charge. WISMO Quik Q24x6 Series also monitors the
temperature of the battery through the BAT_TEMP pin which has to be
connected to a temperature sensor inside the battery (a NTC resistor for
instance).
