Problems solved by technology
Since there are many types of these rechargeable batteries, there are also many types of corresponding chargers, and the chargers are easy to be lost or confused.
If used in confusion, in the case of charging voltage mismatch, it may lead to charging failure, or the charging current is too large to affect the service life of the battery

Embodiment Construction
[0024] Below in conjunction with accompanying drawing and embodiment, the present invention is described in further detail:
[0025] refer to Figure 1-2 : Adaptive battery charging device, including mains transformer module, rectifier filter module, 5V voltage regulator module, voltage acquisition module, voltage comparison module, logic conversion module, charging voltage adjustment module, the output end of the charging voltage adjustment module is used to battery pack charging;
[0026] The mains transformer module is used to transform the 220V mains to obtain 22V alternating current. The turns ratio of the primary coil and the secondary coil of the transformer of the mains transformer module is 10:1. The output end is connected to the rectifier and filter module. The rectifier and filter module is used to rectify and filter the output voltage of the mains transformer module. The output DC voltage of the rectifier and filter module is powered by the 5V voltage stabilizer ...

Abstract
A self-adaptive storage battery charging device includes a mains supply voltage transformation module, a rectifying and filtering module, a 5V voltage stabilization module, a voltage collection module, a voltage comparison module, a logical conversion module and a charging voltage adjustment module. When a storage battery group with 1.5V nominal voltage is connected, the 1.8V charging voltage adjustment module is adopted to charge the storage battery group; when a storage battery group with 3.7V nominal voltage is connected, the 4.25V charging voltage adjustment module is adopted to charge the storage battery group; when a storage battery group with 6V nominal voltage is connected, the 7.5V charging voltage adjustment module is adopted to charge the storage battery group; when a storage battery group with 9V nominal voltage is connected, the 10.625V charging voltage adjustment module is adopted to charge the storage battery group; when a storage battery group with 12V nominal voltage is connected, the 16.25V charging voltage adjustment module is adopted to charge the storage battery group. The self-adaptive storage battery charging device has the advantage of being capable of automatically identifying the voltage levels of the storage battery group and adjusting the output voltage to charge the storage battery group.
Description
technical field [0001] The invention relates to a charging device for a storage battery. Background technique [0002] With the increasing environmental awareness of consumers and industries, the use of alkaline primary batteries and secondary batteries containing the toxic metal cadmium is increasingly restricted, and rechargeable batteries are widely used. On the other hand, as electronic appliances such as digital cameras, MP3 players, mobile phones, and notebooks gradually enter people's lives, the use of rechargeable batteries has become more popular. These rechargeable batteries require a matching charger to charge. [0003] Commonly used are No. 5 and No. 7 rechargeable batteries with a nominal voltage of 1.5V, mobile phone rechargeable batteries with a nominal voltage of 3.7V, and lead-acid batteries with a nominal voltage of 6V and 12V used in toys. Called alkaline batteries with a voltage of 9V, these rechargeable batteries are often used in people's lives. Sinc...
