Problems solved by technology

[0008] The reason for the lack of current products is that there is no constant current and pulse charging circuit, and this circuit has a relatively simple circuit, and can flexibly adjust the relationship between charging and stopping, and the second is that it does not have a limited voltage. A circuit that combines the end of charging (this method is suitable for activated batteries) and the end of timing (this method is suitable for charging non-activated batteries and a large class of batteries such as acid)
The third is that there is no way to use active components for conversion to solve the problem that the charging tube is fragile
If the switch tube is in a pulsed state, it is more likely to become damaged and increase the overall scrapping of the charger

Embodiment Construction

[0099] figure 1 , 2 , 3 and 4 examples show an example of an implementation part, image 3 Example of detection map in implementation.

[0100] 1. Selection of components: The charge conversion diode is composed of two face-to-face diodes connected in series. All triodes use the same type of triode. The counting capacitor is connected in a non-polar form with two electrolytic capacitors, the negative poles of the two electrolytic capacitors are connected, the positive pole of one electrolytic capacitor is connected to the first oscillation terminal, and the other electrolytic capacitor is connected to the counting center point. The end counter uses CD4060.

[0101] 2. Make the circuit control board, welding components: connect figure 2 Make the circuit control board according to the schematic diagram, connect figure 2 Schematic of soldered components.

[0102] 3. Power-on inspection and debugging.

[0103] Check that the welding is correct, and then conduct power-on i...

Abstract

The invention discloses an N-type pulse double-ending constant current charger belonging to the electronic technology. The N-type pulse double-ending constant current charger is constituted by a constant current source, a process display unit, an interface unit, a charging unit, an oscillation unit used for forming pulse, an ending switching unit, an ending starting unit, a timing counting unit, a load unit, and a trickle resistor. After electrification, the constant current source is used to supply all of units with power, and therefore a charging form is constant current charging. The oscillation unit used for forming the pulse is used to control the interface unit to form high output and low output, and is used to control the switching on / off of the charging unit, and therefore a pulse form is formed. Two ending ways are provided, and according to one ending way, charging of a battery is ended, after the battery is fully charged, and according to the other ending way, the charging of the battery is ended, after the timing counting is in place. The ending switching unit is used to switch the two ending ways flexibly and conveniently, and after the charging is ended, the trickle resistor is used to supply the charged battery with required trickle current. The N-type pulse double-ending constant current charger is advantageous in that all of the units are connected together scientifically, and integrated utilization is realized; the line is simple, and is easy to produce, and is suitable for production of mini-sized enterprises.

Description

technical field [0001] It belongs to the technical field of electronic technology. Background technique [0002] With the enrichment of modern life, there are more and more types of electrical appliances using batteries, such as digital machines, mobile phones, etc., and many types of chargers have appeared for this reason, but there are still many types of low-carbon and environmentally friendly charging circuits in these types. exist. [0003] One of its meanings is that in current products, the charging director, which is the circuit transistor that connects and shuts off the charging, is easily damaged. Once damaged, the charger becomes garbage. According to statistics, this failure has become the main failure point of the charger. It is a great waste to turn it into garbage just because of this damage. cost, so people are often throwing away). [0004] The second meaning is that during the charging process, the battery is not charged scientifically, which affects the...
