Embodiment Construction

[0014] Most of the known battery chargers need to manually or use other devices to adjust the battery polarity to complete the normal charging function when the battery is reversed. Some chargers have the function of recharging the battery, but they are all built with discrete components. , occupying a large PCB board area, and accurate detection voltage will further increase the circuit cost. In view of this, the present invention proposes a battery charger that can automatically identify the polarity of the battery and can charge the battery in reverse connection.

[0015] As shown in Fig. 2A, this figure is a simple schematic diagram of a preferred embodiment of the present invention. In this example, a MOS field effect transistor is used as a controlled source, wherein the first field effect transistor (110) is a P channel MOS transistor, which has a source (113), a drain (117) and a gate (115), wherein The source (113) is connected to the power supply, the drain (117) is...

Abstract

A battery charger that can automatically identificate the battery polarity, includes a state / polarity identification module (200), a controller (300) and a rechargeable drive unit (100). Wherein the state / polarity identification module (200) automaticlly identificates the unladen, short-circuit, over-current, positive battery connecting, and reverse battery connecting condition of the charger, and detects the state of the battery, so as to generate the corresponding state signal; the controller (300) controls the switching action of the rechargeable drive unit (100) according to the state signal, thus choosing the correct charging circuit and the charge current, and reaching rechargeable function of battery inverse. The circuit is integrated into a chip and greatly reduces the circuit costs.

Description

technical field [0001] The invention relates to a battery charger. Background technique [0002] The existing charger market is full of various chargers, some of which do not have the function of reverse charging, that is, the battery cannot be charged when the polarity of the battery is reversed, and the battery needs to be adjusted manually or by other devices. polarity to complete the normal charging function; although some chargers have the function of recharging the battery in reverse connection, their circuits are all composed of discrete components, which occupy a large area of ​​the PCB board, and the requirement for accurate detection of the battery voltage will further increase the circuit. cost. In view of this, the present invention proposes a battery charger that can automatically identify the polarity of the battery and that the battery can be charged in reverse connection, and integrates the circuit into the chip, which greatly reduces the circuit cost while ...
