Problems solved by technology

like figure 1 As shown, because the battery charger in the prior art needs to sample and capture the battery voltage and current, the battery voltage sampling circuit is only connected in parallel between the output terminal of the charger and the terminal of the battery to be charged. Such a battery charger will Make the battery generate large power consumption, waste energy, and cannot achieve the purpose of zero battery loss when the battery charger has no input

Abstract

The invention discloses a battery charger, and belongs to the technical field of battery chargers. The battery charger comprises a battery voltage sampling loop connected to the output end of the battery charger in parallel; a diode and an output control switch loop with a microprocessor chip are connected between the battery voltage sampling loop and the anode of output end of the charger. According to the battery charger, when the charger is in a charging state, after the battery is detected to be fully charged, the output control switch loop closes; when the charger is in an idle or zero-input state, an inverse-connection electric-leakage preventing diode and the battery voltage sampling loop may effectively suppress the discharging current of the battery, thus being capable of perfectly playing a role in protecting the battery and also achieving zero power consumption of the battery, and greatly reducing energy waste and consumption; the circuit device can be widely applied to various battery chargers and some special power supplies.

Description

technical field [0001] The invention relates to a battery charger, in particular to a battery charger with zero battery loss when there is no input, and belongs to the technical field of battery chargers. Background technique [0002] In the field of electronic information, energy saving and environmental protection have always been the goal pursued by the industry. For the frequently used power supply and charger, because it may be in an idle state connected to the battery for a long time, the battery requires lower energy saving and smaller size. Discharge current and longer service time are particularly important. Reducing loss and saving energy are the inevitable pursuit of the development of the power supply industry. [0003] With the increasing development of the power supply industry and the continuous improvement of product requirements, the industry has introduced requirements to reduce energy consumption in power supplies, batteries, etc., with the goal of saving ...
