Charger for automatically recognizing battery

Abstract

The invention relates to a battery charger, in particular to a charger for automatically identifying batteries. The battery charger comprises a transformer, a rectifier, controllable silicon, a current detector, a singlechip and a voltage detector. The controllable silicon is connected with the transformer and the singlechip respectively, which converts alternating current output by the transformer into constant DC which is provided for batteries. The current detector is connected with the controllable silicon and the singlechip respectively. The current detector detects the current of batteries charged from time to time, and feeds the current signals back to the singlechip; the singlechip is connected between the rectifier and the voltage detector, and used for determining the types and the capacities of the batteries and outputting control signals for adjusting the turn-on time of the controllable silicon; the voltage detector monitors the voltages at the two ends of the batteries charged from time to time, and feeds the voltage information back to the singlechip. The battery charger can automatically determine the types of the batteries, and can control the time and the magnitude of charging current and charge various types of batteries.

Description

technical field [0001] The invention relates to a battery charger, in particular to a charger for automatically identifying batteries. Background technique [0002] With the progress of society and the improvement of material life step by step, there are more and more high-end electronic products and portable electric tools that need to be powered by batteries. However, different equipment and tools need to be equipped with different batteries and the voltage of the battery is also different. The capacity of the battery is also different, especially the capacity of the lead-acid battery, which is as small as a few ampere hours and as large as hundreds of ampere hours. In order not to waste materials, most of the batteries used today are rechargeable batteries, but for various types of batteries, almost every charger can only charge batteries of one or several capacities. Otherwise, charging a large-capacity battery with a low-current charger will take too long; charging a s...

Problems solved by technology

In order not to waste materials, most of the batteries used today are rechargeable batteries, but for various types of batteries, almost every charger can only charge batteries of one or several capacities.

Otherwise, charging a large-capacity battery with a low-current charger will take too long; while charging a small-capacity battery with a high-current charger will easily overcharge and damage the battery.

This not only causes a variety of chargers at home, which not only wastes resources, but also increases the consumption cost of consumers, and also brings inconvenience to consumers.
