Description

M37J787 V. New description: [New technical field] This creation is related to a charging control circuit, especially a charger charging control circuit that is installed in the battery holder as a real voltage detection and anti-overcharge for different attributes of the battery. [Prior Art] With the rapid development of technology, various portable electronic products and electrical equipment have become more and more popular, and gradually become important household appliances and daily necessities. However, most of the main energy sources of these electronic products are from The battery, in order to meet the power supply of various electronic products, has developed batteries with different properties. Regarding the type of battery, it can be divided into: The first type: Primary cell, that is, the chemical energy that can only be converted as much as possible with the loss of the electric capacity, so that it cannot be utilized again by the charging method. Representative products are dry batteries (generally carbon zinc batteries), mercury batteries and alkaline batteries.

The second type: secondary battery (secondaiy battery) 'can use the charging method to make the active substance in the battery return to the original state again, and obtain the characteristics of reusable use. 'Representative products have lead acid battery (lead acid battery) Nickel cadmiun batter, nickel hydrogen batter, secondaiy lithium batter, and lithium ion battery (Hthiumionbatteiy) and polymer lithium batter. The third type: a fuel cell (foel cell), characterized by two poles and no active material, is completely supplied through an external system, and can be used as long as the external system is continuously supplied. 3 The product is currently the most oxyhydrogen fuel cell (10). Qing. Xin n fUd Γ丨丨). And the paste, the money, the supermarket can be the first to the secondary battery, as well as the more economical, environmentally friendly secondary batteries. However, as far as we know, secondary batteries such as carbon batteries, inspective batteries, or secondary batteries such as battery recording locks and hydrogen recording batteries are required to meet the needs of most small household appliances. Among them, 'carbon zinc, test, clock battery, nickel ore and nickel-metal hydride batteries, although the voltage is missing: L5V 'but the actual voltage tends to be slightly lower (such as blue, ι, etc.), or slightly the same (such as 1.52V, 1.53V, etc.) But the charging voltage of the charging stand is fixed at ^ 5v, plus the general charger has an anti-overcharge and power-off circuit, but the anti-overcharge and power-off circuit needs to have a voltage of 1.5V. State, the party will automatically power off to prevent overload. The edge is 'if the battery with different actual properties such as the test battery, the clock battery, the mining, the gas recording, etc., the single-charger is charged, but the actual voltage is lower than the UV is saturated. The capacity of the capacitor f exceeds the actual voltage threshold (because the voltage does not reach the standard 15V setting, so the voltage will continue to be supplied), which leads to shortened battery life, moderate to high temperature burns, and serious cases. The battery can't produce the technical problem of 危安. In view of the above-mentioned existing chargers, it is impossible to detect the battery in the state of charge, the actual saturation voltage, and the problem of the battery voltage over-filling, and the technical problems such as the use and life-threatening problems that have been derived from the industry are urgently required to be completely solved by the industry. [New Content] This creation mainly provides charging control circuits for battery chargers that have overcharged, overheated, exploded and extended battery life. The charging control circuit of the battery charger used to achieve the above objective, the charging control circuit is mainly disposed on the circuit board of the battery charger, and includes: a power source; and an external power source for inputting and converting a rectifying and stabilizing circuit; a charging circuit electrically connected to the rectifying and stabilizing circuit, the charging circuit and the output of the voltage and current are controlled to be large and small; and a detecting circuit electrically connected to the charging circuit, the detecting circuit is For the battery in the state of charge, voltage, current and temperature detection are performed, and the signal is transmitted to a control circuit of the electrical connection. After the control circuit demodulates the variable signal, an indication signal is sent to the charging circuit and charged. The current in the circuit transmission is adjusted or adjusted to control the output voltage to meet the actual voltage value of the battery in the charging, so as to avoid battery burnout, explosion and shortened service life caused by overcharging. Detailed charging control circuit technology is provided with a simple circuit block diagram as explained below. [Embodiment] The present invention relates to a charging control circuit for a charger, which is disposed on a circuit board 2 of a battery charger 1, and includes: a power supply 1 〇, which may be a general 110V-220V The mains power can also be a 12V DC power supply for vehicles, or even a DC power supply for PC, NB, etc., which is transmitted via USB as a medium. The figure is based on the most easily available commercial power. The power source 1 (10) is electrically connected through the receiving end 11 (plug) directly or indirectly provided by the charger 1 to achieve mutual conduction supply. If the power source M377787 is a vehicle 12V DC, the receiving end is a receiving terminal form, and the USB For the power output medium, use the USB plug. A rectifying and stabilizing circuit 2 0 'will flow through the plug into the external ac power supply, perform voltage conversion and AC to DC conversion function' or input external power supply voltage conversion function; a charging circuit 30, system and rectification The voltage circuit 2 is electrically connected, and the voltage or current output value after the rectification is controlled to be large or small; the Luyi detection circuit is connected to the charging circuit 30, and the actual voltage is applied to the battery in the charging state. Detecting, supplying current detection and battery temperature detection; and a control circuit 50' electrically connecting the detection circuit 40 and the charging circuit 3 0 'the control circuit 50 can receive the detection circuit 4 〇 The detection signal is then demodulated by the control circuit to send the control signal to the charging circuit 3, and the charging circuit 30 adjusts the voltage and current output according to the received signal. It meets the best saturation saturation voltage efficiency of the battery under current charging conditions. In addition, the charging control circuit can also be provided with a display circuit 6 〇, and the display circuit 60 is electrically connected to the charging circuit 3 to receive the output signal of the charging circuit at any time to obtain a message of charging or being fully charged. In order to allow the user to interpret the state of charge of the battery as described above, as for the charging or full display mode of the display circuit 6 , an illuminant (for example, an LED) is disposed on the battery charging path 1 to illuminate the illuminant. Or the status of the xenon lamp is interpreted, or the color difference of the illuminant is used for interpretation; or the buzzer means can be used to remind the user by sounding the state of fullness, or 6 M37.7787 with different sounds and sounds Large, small, fast, slow and other means to provide users with the basis for interpretation.

If the actual voltage is found to be unbalanced with the input battery after mutual comparison, the detected signal will be transmitted back to the charging circuit via the control circuit, and the signal will be sent to the charging circuit to increase or decrease the current output current. set up. When the detection circuit detects that the output voltage is equal to the actual voltage of the battery, the signal is transmitted back to the charging circuit via the control circuit to interrupt the output of the current to avoid overcharging of the battery during charging, so that the charged battery is maintained at The best saturation state, in order to play the longest use aging, and extend the overall battery life, and thus prevent battery overcharge explosion, burning and other conditions. In addition, the detection circuit can not only detect the actual voltage function of the battery in the charging, but also have the detection function for the output current of the charging circuit.
