Problems solved by technology
[0007] However, according to the above-mentioned charging method, the conventional circuit also has technical difficulties, because the conventional circuit is not a circuit that charges and discharges, and its switch control tube is the focus of the fault. If the switch tube is in a pulsed state, it will be easier. The probability of becoming damaged is one, and the second is because the circuit has the control of charging and the control of discharging part (or stop charging), so the damaged part has doubled, so if the traditional design is used, it must be The circuit is complicated, and new fault points have been added. How to solve these contradictions has become a new difficulty

The invention provides a low-carbon silicon controlled rectifier type environment-friendly charger, and belongs to the electronic technology. The charger is formed by an innovative silicon controlled rectifier charging unit, an execution control unit, an annular oscillation type pulse generation unit, a charging display unit, a discharge unit, an end-start adjustable threshold unit, an end shaping amplification unit, an end control circuit, and a load unit. When the innovative silicon controlled rectifier charging unit is charging, the discharge unit is switched off; when the innovative silicon controlled rectifier charging unit is switched off, the discharge unit is switched on, and a pulse charging pattern in which the charging time is longer than the discharge time is formed; when a charged cell is fully charged and a threshold of the end-start adjustable threshold unit is reached, the end shaping amplification unit is started, and the innovative silicon controlled rectifier charging unit and the discharge unit are switched off. A maintenance trickle current is provided for the charged cell by a trickle resistor in the innovative silicon controlled rectifier charging unit, quick-break of the silicon controlled rectifier is realized through the innovative silicon controlled rectifier, the switch-on and switch-off of the innovative silicon controlled rectifier charging unit can be guaranteed, and a backup circuit forms the charging substitute so that the lifetime of the charger and the charged cell can be guaranteed.
Description
technical field [0001] It belongs to the field of electronic technology. Background technique [0002] Our company applied for a series of security products some time ago, and this product must have a backup battery, otherwise, when there is no mains power, the security function will become a fake, and when there is no mains power, it may be the peak of security accidents when. So a backup battery is required. And the performance of the backup battery is directly related to the overall performance. [0003] But the backup battery must be charged and maintained, and the scientific maintenance of the backup battery is directly related to the life and capacity of the backup battery. Some sources believe that batteries are often not worn out, but damaged due to improper charging. Batteries in security equipment are special-purpose batteries, which have special requirements for volume and capacity, and are more demanding than general products. Therefore, how to ensure that t...
