Problems solved by technology

The disadvantage of this control method is that the maximum voltage of the fully charged battery varies with the ambient temperature and charging rate, and the maximum charging voltage of each single battery in the battery pack is also different, so it is impossible to judge the battery very accurately with this method. fully charged
The disadvantage of this control method is: after the battery voltage has a negative increment, the battery has been charged, so the temperature of the battery is relatively h

Embodiment

[0062] Such as figure 1 , 2 , 3 and 4, the universal fast smart charger is mainly composed of the following modules:

[0063] The power supply module adopts a switching power supply to supply the power required for the charger to work;

[0064] The battery detection and analysis module is mainly composed of a single-chip microcomputer, a voltage divider network and a pre-charging unit. Firstly, it is identified whether the pre-charged battery is within the rechargeable range? If it exceeds the charging range, an over-range alarm will be issued; if it is within the charging range, it will further identify whether it is low-voltage charging (less than 36V) or high-voltage charging (not less than 36V)? Identify the type and number of batteries when charging at low voltage; identify whether the rechargeable battery is 36V or 48V when charging at high voltage? During the working process of the charger, provide parameters for the comprehensive control and detection module in real...

Abstract

The invention discloses a general rapid intelligent charger and a charging method thereof, mainly comprising a power module, a battery test analysis module, a charging parameter regulation and dynamic control module, an integrated control test module, a charging module and an indication module. Adopting a single chip as a control unit, the charger incorporates four storage battery charging control processes of pre-charging control, rapid charging control, supplementary charging control and trickle charging control to realize the whole process control of charging execution circuit, thus greatly improving the charging effect and effectively prolonging the actual life of battery. The charger can also identify different battery types, adjust the charging procedures of the controller according to the optimum charging curve automatically and charge different types of storage batteries.

Description

technical field [0001] The invention belongs to the field of household electrical appliances, in particular to a general-purpose fast intelligent charger based on comprehensive detection and dynamic control. Background technique [0002] With the development of social economy, more and more electrical appliances have entered people's daily life, and the number and types of small-capacity batteries used in households have increased significantly. If we equip each type of battery with a charging Obviously, it will cause a great waste of resources, and with the aging of the battery, there will be more and more problems, which will eventually lead to the decline of the battery life. The increase of discarded batteries (the chargers are also discarded) will greatly pollute the environment. Therefore, it is very important to study how to prolong the service life of the storage battery, and to design and produce a high-quality, high-efficiency, universal fast smart charger that me...
