If the electricity from the generator is 17V, 1Check whether the battery cable and generator + pole are open? If the circuit is open, it is normal for the generator voltage to be 17V, because the electricity from the generator does not enter the battery.

2.If it doesn't open the circuit, see if the generator regulator is broken? That is, the regulator F and + are short-circuited (straight-through).

The generator in the case of the regulator is normal should be to see if your meter is inaccurate? Measure it on a different table.

Hello dear, I'm glad Kai pants answered for you: if a 12V generator is charged to 17 volts, it may mean that the generator itself is faulty or the circuit is incorrectly wired. If the generator output voltage is too high, it may cause problems such as evaporation of battery electrolyte liquid and overheating of the charger, which may eventually lead to battery damage, charger damage and circuit failure.

In addition, if the generator output voltage is too high, it may also have an impact on the on-board electronics, which can damage the electronics or damage them dangerously. Therefore, the generator and circuits need to be checked in time to ensure that the generator can work properly and output the correct voltage.

The 7806 three-terminal regulator can be used to change the output voltage to 6V;

Because a fixed three-terminal regulator is a series regulator circuit, its principle is equivalent to that of a series regulator.

The voltage divider composed of R1, RP and R2 is a sampling circuit, and a part of the voltage UB2 is taken from the output terminal as the sampling voltage and added to the base of the transistor T2. The regulator DZ is applied to the emitter of T2 with its stable voltage uz as the reference voltage. R3 is the current-limiting resistor of the regulator tube.

The triode T2 forms a comparison amplification circuit, which compares and amplifies the sampling voltage UB2 with the reference voltage UZ, and then controls the base potential of the triode T1. The input voltage UI is added to the circuit where the triode T1 is connected in series with the load RL, so the voltage UO at both ends of the RL can be adjusted by changing the voltage drop between the collectors of T1 UCE1. In other words, the output voltage UO of the regulator circuit can be adjusted by the triode T1, so T1 is called the adjustment tube.

Since the trim element is a transistor and is connected in series with the load in the circuit, it is called a transistor series regulator circuit. The base bias resistors of resistors R4 and T1 are also the collector load resistors of T2.

When the output voltage decreases due to the decrease of the grid voltage or the decrease of the load resistance, the sampling voltage UB2 decreases accordingly, and the base potential of T2 decreases. However, because the T2 emitter potential and the stable uz of the regulator tube remain unchanged, the emitter voltage UBE2 decreases, resulting in a decrease in the T2 collector current and an increase in the collector potential UC2. Since the collector of the amplification tube T2 is connected to the base of the adjustment tube T1, the base potential of T1 increases, resulting in the increase of the collector current and the decrease of the voltage drop of the tube UCE1.

Since T1 is connected in series with RL, the output voltage UO is basically unchanged.

In the same way, when the output voltage UO increases due to the change of grid voltage or load, the voltage drop UCE1 of the adjustment tube will increase through the process of sampling, comparison amplification, adjustment, etc., and the increase of the output terminal voltage is inhibited, and the output voltage remains basically unchanged.

You can buy a three-terminal regulator tube with a nominal output value of 6V

It is also possible to buy a high-power regulator diode, and add a current-limiting resistor and connect it to the output.

There is a special step-down chip, down to 6V with LM7806, the 3-volt circuit is a little more complicated, you can also make an adjustable voltage regulator circuit, adjustable from 0-12V ( weakly ask the xiepenghuii on the second floor, the battery is direct current, how to use the transformer? Is a step-down transformer necessary? ）

Five 12-volt batteries are connected in series, and their voltages add up to 60 volts.

1. The device that converts chemical energy into electrical energy is called a chemical battery, which is generally referred to as a battery.

2. After discharge, the internal active material can be regenerated by charging - the electrical energy can be stored as chemical energy; When an electric discharge is required, the chemical energy is converted into electrical energy again. This type of battery is called a storage battery, also known as a secondary battery. The so-called storage battery is an electrochemical device that stores chemical energy and emits electrical energy when necessary.

It depends on your current requirements and accuracy requirements.

If the accuracy is high, choose an LDO chip with adjustable voltage to do it;

If the accuracy requirements are average, the simplest is to use a chip such as TL431 and add a BJT transistor.

When the 12-volt generator charges the battery, first make the positive and negative poles of the generator clear. If there is a charging adjuster, it is carried out through the shu regulator, if it is not wired according to the following figure:

The rectifier diode model in the figure is 6A10, the maximum working current is 6A, which can be used for general battery charging (below 60Ah battery), its function is to prevent the current from returning to the generator, and play an interception role, also called the interception diode. The electrolytic capacitor is a filter capacitor, which makes the voltage more stable, and the parameter is 2200UF 25V.

When charging the battery of the 12-volt generator, first make the positive and negative poles of the generator clear. If there is a charge regulator, it is done through the regulator, if it is not wired as shown in the figure below.

The electricity generated by the DC 12-volt generator can be charged to the 12-volt 75-ampere battery, but the voltage is low and the battery is insufficient, and the electricity generated by the AC 12-volt generator can be charged to the 12-volt 75-ampere battery after rectification, and it can be sufficient.

If it is a 12-volt car generator, its output voltage is definitely more than 12 volts, it is higher, it is specially designed for 12-volt battery charging.

The picture above is a circuit used in a car to charge the battery by a generator.

The battery is a lead-acid battery, the voltage is normal, the lead-acid battery is just fully charged at 14V to 15V, and after a period of time, it is at 13V to 14V

Hello:——1,The voltage of the battery and rechargeable battery after sufficient charge is twice the rated voltage. A battery with a rated voltage of 12 V will be fully charged when the voltage rises to V when charging.

The voltage of the battery and rechargeable battery is called the "limiting voltage" and its meaning is the same as the limiting voltage of the lithium battery of the mobile phone: v lithium battery, charged to v is fully charged.
