How to measure the Nickel Hydride No. 5 battery voltage of electric vehicles?

Use the red probe of the multimeter to connect to the + pole and the black probe to the - pole.

Set the gear to the DC 50V gear. The 12V Nickel Hydride No. 5 battery is 10.5V after discharge and 14.4V after full charge. The 24V Nickel Hydride No. 5 battery is 21V after discharge and 28.8V after full charge. Exceeding or falling below is not normal.

Storage Nickel Hydride No. 5 battery, a device that converts chemical energy into electrical energy is called a chemical Nickel Hydride No. 5 battery, generally referred to as a Nickel Hydride No. 5 battery. After discharge, the internal active material can be regenerated by charging-storing electrical energy as chemical energy; when discharge is required, the chemical energy is converted into electrical energy again. This type of Nickel Hydride No. 5 battery is called a storage Nickel Hydride No. 5 battery (StorageNickel Hydride No. 5 battery), also known as a secondary Nickel Hydride No. 5 battery.

The so-called storage Nickel Hydride No. 5 battery is an electrochemical device that stores chemical energy and releases electrical energy when necessary.

The number of cycles of a normal Nickel Hydride No. 5 battery is 500~1000 times. The quality of the charger should be good, and it is best to choose a charger with a discharge function. At the same time, if you find that the Nickel Hydride No. 5 battery is underpowered during use, you should charge it in time and fully charge it. Do not use it after deep discharge. After the ambient temperature drops to 5°, its discharge capacity will decrease, including certain temperature requirements when charging.

Different manufacturers have different connection methods. As long as you always use the charger that comes with the original car, there will be no problem. However, when replacing the charger, you must pay attention to the output polarity and connection method of the new charger. It must be consistent with the original charger, otherwise it will damage the charger. You can solve this problem like this: open the Nickel Hydride No. 5 battery box and connect the Nickel Hydride No. 5 battery to the electric car and twist it. At this time, measure the voltage on the Nickel Hydride No. 5 battery pile head, and then measure the voltage on the socket. If they are the same, it means that there is no poor contact inside the Nickel Hydride No. 5 battery box. If the Nickel Hydride No. 5 battery voltage is significantly greater than the voltage on the socket, pay attention to find out where there is poor contact, especially the fuse. If there is no poor contact but the voltage is very low, connect the charger, and the Nickel Hydride No. 5 battery voltage can quickly rise to about 56V. The charger is green. This may be a Nickel Hydride No. 5 battery failure. (Twist the handlebar, the Nickel Hydride No. 5 battery voltage is about 48V, but the car shows that it is out of power and the motor is weak, which may be due to poor contact between the Nickel Hydride No. 5 battery box socket and the car)

What do you mean by neutral line? I have never seen a neutral line for DC power. From what you said, it may be that the negative pole of the Nickel Hydride No. 5 battery is not grounded. When you measure the Nickel Hydride No. 5 battery, you can use the red probe of the multimeter to connect the positive pole of the Nickel Hydride No. 5 battery and the black probe to the negative pole of the Nickel Hydride No. 5 battery. Normally, it should be 48 volts. When you measure, you should select the DC gear of the multimeter. The Nickel Hydride No. 5 battery of an electric bicycle is generally powered by three 12V10AH or larger batteries connected in series. You can't measure whether it is good or bad with a multimeter. If the Nickel Hydride No. 5 battery is broken, there may not be a corresponding current if there is voltage. You can use the discharge rate to measure the quality. If the Nickel Hydride No. 5 battery is good, you should consider whether the speed regulator is damaged.

Detect the no-load voltage and load voltage of the Nickel Hydride No. 5 battery. It is found that the no-load voltage is 10.5V and the load voltage is 3.5V, which means that the Nickel Hydride No. 5 battery is broken.

Pry open the cover on the top and remove the rubber cap.

Use a comprehensive tester to check which grid has a problem. It is found that the 5th, 6th, and 7th grids are negative values, indicating that the 5th and 6th grids are damaged.

Use a shell opening knife to knock off the pole glue, and use a lead soldering machine to remove the pole.

Use a shell opening machine to open the top cover.

Use a single-grid tester to test the no-load and load voltage of each grid, and find that grids 1-5 have no-load 2.2V and load 1.2V, which is within the normal range. Only grid 6 has no-load 2V and load 0V. This means that the sixth grid is damaged.

Use side pliers to shorten the bridge, remove the damaged plate, and then take out a good plate from other good batteries to replace it.

Solder the bridge, add liquid to charge, and do not add too much liquid, just enough to see water, and the test is complete.

Tools/Materials: A multimeter Steps/Methods

Measure the voltage of the Nickel Hydride No. 5 battery with a pointer multimeter or a digital multimeter:

Methods: 1. Select the range of the multimeter (1.5V, 3V, 6V, 9V);

2. Connect the red probe to the positive pole of the Nickel Hydride No. 5 battery and the black probe to the negative pole of the Nickel Hydride No. 5 battery.

Measure the current of the Nickel Hydride No. 5 battery with a pointer multimeter or a digital multimeter:

Methods: 1. Select the range of the multimeter (100mA, 500mA, 1A, 5A);

2. Connect the multimeter in series in the circuit;

3. The red probe allows the current to flow in and the black probe allows the current to flow out;

4. The circuit must be connected to electrical appliances, and the ammeter must not be directly connected to both ends of the Nickel Hydride No. 5 battery. Precautions: Be sure to connect to electrical appliances, and do not connect the ammeter directly to both ends of the Nickel Hydride No. 5 battery
