Battery charger combining charging time and service life of battery

Abstract

The invention relates to a battery charger combining charging time and the service life of a battery. The battery charger comprises a master controller, a charging control circuit, a voltage acquisition module, a current acquisition module, a temperature detection module, a protective circuit module, a working state indication module, a display module and a power conversion module, wherein the master controller is connected with the charging control circuit, the voltage acquisition module, the current acquisition module, the temperature detection module, the protective circuit module, the working state indication module and the display module respectively; and the charging control circuit, the voltage acquisition module, the current acquisition module and the temperature detection module are connected with the battery to be charged respectively. The battery charger further comprises a human-computer interaction module connected with the master controller. Compared with the prior art, the battery charger has the advantages of enabling a user to self-define the charging time and realizing reduction in the ageing of the battery by regulating a charging rate under the condition of relatively longer charging time, prolonging the service life of the battery, and the like.

Description

technical field [0001] The invention relates to a battery charger, in particular to a battery charger which takes both charging time and battery life into consideration. Background technique [0002] With the rapid development of science and technology, secondary batteries are widely used in various fields. The ability of a battery to actually store power is an important parameter to measure battery performance. For the same battery (group), there is a great correlation between the power that can be released and the power that can be charged, so the power charged is a measure of battery life. An important indicator, in order to ensure the normal operation of the device for a long time, the battery needs to store enough power, which requires charging as much power as possible within the time allowed by charging; secondly, the service life of the battery is also a crucial It is of great significance to reduce the cost of equipment and protect the environment to maximize batte...

Problems solved by technology

[0003] The charger is a special device for supplementing battery energy, but the chargers currently on the market can only charge according to the default setting mode. The shortcomings of this type of charger can be summarized as follows: (1) Users cannot set The charging time, the charging process cannot be controlled, and the charging speed cannot be adjusted; (2) The charger charges according to a fixed charging rate, and the effect of the charging rate on battery aging is a fixed value. The controller cannot realize the function of reducing battery aging and prolonging battery life by adjusting the charging rate
