Problems solved by technology

[0002] At present, the commonly used multi-gear battery chargers mostly charge the battery mechanically after the user connects it. However, in some cases, the user may connect the charger to the wrong gear. The battery cannot be effectively charged if the low-voltage gear is placed; in other cases, the low-voltage battery is connected to the high-voltage gear, so the battery will be damaged

Embodiment Construction

[0016] In order to further illustrate the essence of the invention of the present invention, a preferred embodiment will be described in detail below in conjunction with the accompanying drawings: This embodiment is a step for automatically judging the voltage of a charging battery in a 12V / 24V charger to prevent mischarging, as shown in the figure: 1st The first step is to select the gear position to electrify the storage battery, but in order to prevent wrong selection, the second step of the present invention is to charge the storage battery with a current of 28V and a constant 1A for 20S, and the maximum voltage is limited to 28V, and the third step is to charge the storage battery voltage. Sampling, compare the sampling voltage, if the sampling voltage value is higher than 16V, it can be preliminarily determined that it is a 24V battery. After the voltage sampling and comparison, step 41 stops charging for 10 seconds, and step 51 samples the battery voltage to determine whe...

Abstract

Present invention relates to a charger automatically judging charging accumulator voltage preventing miss charged method. Said method can automatically judge accumulator voltage, automatically adjusting charging position, in time stopping charging in charger user switching wrong position to protect accumulator and sending alarm signal. In said method, user selecting charging switch position in the beginning of charge, in process of charging to sample and compare by multiple times to accumulator to determine whether user is miss charging and whether connected accumulator is normal, which can prevent accumulator damage due to miss charging and capable of automatically selecting suitable switch position for charging.

Description

technical field [0001] The invention relates to a method for automatically controlling the charging of a charger, in particular to a method for automatically judging the voltage of a charging battery by a battery charger to prevent mischarging. Background technique [0002] At present, the commonly used multi-gear battery chargers mostly charge the battery mechanically after the user connects it. However, in some cases, the user may connect the charger to the wrong gear. The battery cannot be effectively charged if the low-voltage gear is turned on; in other cases, the low-voltage battery is connected to the high-voltage gear, and the battery will be damaged. Therefore, a method that can automatically determine the voltage of the battery, automatically adjust the charging gear, and stop charging in time to send a signal to remind the user to protect the battery when the user connects to the wrong gear can successfully solve the above-mentioned hidden worries.
