In a first charging phase the charging circuit charges the batteries with a large current and at a second charging phase the charging circuit charges the batteries with a much smaller current. The charging circuit includes a current detection circuit which detects a charge current and provides a detection voltage proportional to the charge current. The battery charging control circuit also includes an amplifier circuit to amplify the detection voltage and a comparison module compares the amplified detection voltage with a reference voltage. If the amplified detection voltage is lower than the reference voltage, the comparison module outputs a switch signal to a control module. The control module controls a charging module to charge the battery in a trickle mode when receiving the switch signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Battery charging circuit with trickle charging mode","description":"The present invention provides a battery charging control circuit to charge batteries in phases.
