Problems solved by technology

However, the defect of this technology is that it uses the traditional split transformer magnetic induction power supply method, which is the one with the lowest efficiency and the smallest transmission distance in the wireless induction power supply technology; When passing through the metal shell of the farad capacitor, a strong eddy current will be induced. In CN202334009U, no means are used to prevent the generation of the eddy current, which will inevitably cause the eddy current to consume unnecessary electric energy, which will not only greatly reduce the power supply efficienc...

Description

technical field [0001] The invention relates to a device in the technical field of daily necessities, in particular to a capacitive energy storage rechargeable battery that can replace a dry battery and a charging device thereof. Background technique [0002] At present, many electronic devices are powered by dry batteries, such as remote controls of household appliances, wireless mice, electronic clocks, and electric toys for children. Most of these devices consume very little power, such as household remote controls, the standby power consumption is only microwatts, the current consumption during transmission is only 10-20mA, and the duration of infrared transmission is very short, usually at the millisecond level, only dry batteries can Work for months or even longer. Some consume more power, such as children's electric toys, which consume a lot of battery when used. These electronic devices consume billions of dry cells every year. Because dry batteries contain heavy ...
