Charging control method of battery and charger

Abstract

The invention discloses a charging control method of a battery and a charger. The charging control method of the battery comprises the following steps: a temperature compensation corresponding relationship of multiple types of batteries is integrated into a control software and programmed into the charger in advance; in the subsequent battery charging control, the corresponding temperature compensation corresponding relationship can be directly determined according to the received type information of the battery to be charged; and the charging control is performed according to the current temperature of the battery to be charged and the determined temperature compensation corresponding relationship. Therefore, by using the charging control method of the battery, each charger only needs tobe programmed with the one control software integrated with the temperature compensation corresponding relationship of the multiple types of batteries; therefore, the tedious process of individually configuring control software for different types of batteries is eliminated, the programming errors caused by frequently changing and programming the control software are avoided, the mismatch betweenthe temperature compensation corresponding relationship and the battery is effectively prevented, and the charging reliability and safety of the battery are improved.

Description

technical field [0001] The invention relates to the technical field of storage battery charging, in particular to a storage battery charging control method and a charger. Background technique [0002] At present, there are many kinds of storage batteries. The batteries commonly used in railway passenger cars usually include nickel-cadmium type and nickel-hydrogen type. In addition, the charging and discharging current of the battery can be divided into medium rate and high rate. When charging, it is supplemented or float charged according to the corresponding temperature compensation relationship of the storage battery, so as to meet the demand for emergency power supply of the storage battery. [0003] The control software in the charger (including the temperature compensation correspondence) must perform a series of settings such as the highest voltage, the lowest voltage, and the current limit value according to their respective temperature compensation correspondences.

Problems solved by technology

If there are many types of batteries, it is necessary to burn different control software into different chargers. The burning process is cumbersome, and it is easy to cause wrong programming, which will cause a mismatch between the temperature compensation correspondence and the battery, and cause Abnormal charging or even battery damage reduces the charging reliability and safety of the battery
