How many Vs is 72V connected in parallel with 72V. Can I charge it with a 72V charger after connecti

If the battery performance is the same, it can be connected in parallel, the battery voltage is still 72V, but the capacity is large, and the charging time will be extended with a charger.

The voltage of parallel connection is unchanged, after parallel connection is still 72 volts, you can add a switch after parallel connection, and then only use one, and then you can use only one charger.

The battery parallel voltage does not change and can be charged with a 72-volt charger.

It should be around 12v. It is not possible to charge.

The 72V battery and the 72V battery are connected in parallel, and the voltage after parallel connection is still 72V.

When it comes to charging, it's not that simple. At present, the charging method is usually constant voltage charging, so the charging voltage is very critical; Another charging parameter is the charging current, which determines the length of time to fill and the life of the battery.

To put it simply, the charging voltage should be higher than the rated voltage of the battery, and at present, most options are about times the rated voltage of the battery. The charging current should be selected according to the rated capacity of the battery, and the basic value is greater than the multiple of the battery capacity. Combined, these two parameters determine the charger's capabilities.

To put it a little simpler, if the capacity of two 72V batteries in parallel is equivalent to the capacity of an electric vehicle battery or smaller, for example, the capacity is less than 32ah, you can use the charger of a 72V electric vehicle to charge these two batteries.

How many volts is 72V connected in parallel with 72V? Can I charge it with a 72V charger after connecting it together?

A: Parallel or 72 volts, available for charging.

How many volts is 72 volts in parallel with 72 volts? Can I charge with a 72 volt charger after paralleling?

A 60V charger cannot charge a 72V battery.

The charger and battery are matched, and the voltage range of the 60V battery is basically between 50V and 70V. The voltage of the battery is not a fixed value, but floats within a certain range on the basis of the nominal voltage, and the upper limit of the charging termination voltage is generally a multiple of the nominal voltage; The lower discharge cut-off voltage is generally the nominal voltage.

For a 72-volt battery, the upper limit of the charge voltage = volts, while the lower limit of the discharge cut-off voltage is volts. For 60 volt batteries, the upper limit of charging voltage = volts, while the lower limit discharge cut-off voltage = volts.

Chargers (chargers) are divided into power frequency machines and high-frequency machines according to the working frequency of the designed circuit. The power frequency machine is based on traditional analog circuits.

In principle, the internal power devices (such as transformers, inductors, capacitors, etc.) of the machine are larger, and there is generally less noise when the load is large, but the model has strong resistance in harsh power grid environmental conditions, and its reliability and stability are stronger than that of high-frequency machines.

Whereas high-frequency machines are microprocessors.

CPU chip) as a processing control center, is to burn the complicated hardware analog circuit into the microprocessor, in the form of software programs to control the operation of UPS.

As a result, the volume is greatly reduced, the weight is greatly reduced, the manufacturing cost is low, and the selling price is relatively low. The inverter frequency of high-frequency machine is generally above 20kHz. However, the high-frequency machine has poor tolerance under harsh power grid and environmental conditions, and is more suitable for the environment where the power grid is relatively stable, the dust is less, and the temperature and humidity are suitable.

It is not possible for a 60v charger to charge a 72v battery.

Because the output voltage of the charger is much lower than the rated voltage of the battery, the charger will not be able to fully charge the battery, so that the battery will be in a feeding state for a long time, which will seriously affect the service life of the battery.

When the battery voltage is lower than the output voltage of the charger, the charger can temporarily charge the battery; As the internal voltage of the battery increases, when the internal voltage of the battery reaches the same as the output voltage of the charger, the charger cannot continue to charge the battery.

It's not the same.

1. In terms of price: 72v20ah is a little more expensive than 72v3a.

2. Capacity: 72V3A has more capacity than 72V20Ah, which is basically a double, which affects the battery life of 72V3A for a longer time.

3. Self-weight: 72V3A is heavier than 72V20Ah, and the volume must be a little larger, so the output needs to be a little more.

4. Durability: 72V3A is more durable than 72V20Ah.

The above situation is based on the premise that the same car is used to drive the same person, and the two types of batteries are of the same material.

72V32Ah, which describes the rated voltage of a battery.

It is 72 volts, the rated discharge current is 32 amps and the capacity of the battery.

The higher the voltage, the higher the efficiency of the system, if the voltage is high under the premise of the same capacity, it means that the current will drop at the same power. So theoretically, the higher the voltage of the car, the farther the car can theoretically.

AH is the meaning of ampere-hours, 20ah, which is equivalent to continuous 20 amperes can discharge for an hour; And 3A, which is equivalent to 32 amps, can continue to discharge for an hour, if only the current is considered, 3A will be much stronger.

Summary. The 60V charger cannot charge the 72V battery, because the 72V battery needs the charging voltage of the charger to be about 85V, and the maximum output charging voltage of the 60V charger is only a little more than 70, and the 72V battery cannot be fully charged at all.

Can a 60V charger charge a 72V battery?

No. The output voltage of the battery charger should be greater than the rated voltage of the battery, for example, the output voltage of the 12V battery charger should be greater, so the charger with an output voltage of 60V cannot charge the 72V battery, and the charger with an output voltage greater than 85V is needed to charge the 72V battery.

Will it damage the charger if it is charged?

Yes. It will cause the battery to be used for a short period of time and will not be fully charged.

The 60V charger cannot charge the 72V battery, because the 72V battery needs the charging voltage of the charger to be about 85V, and the maximum output charging voltage of the 60V charger is only a little more than 70, and the 72V battery cannot be fully charged at all.

I'm talking about chargers.

Not a battery? I'm talking about a 60V charger and a 70V battery.

My family used this before.

As a result....The charger is broken and burned. Well.

Yes, the charger voltage is the same, the current is different, it can be charged, the difference is that the charging speed of 20A will be slower than the charging speed of 22A, and it will take longer! Also pay attention to lead-acid batteries.

It cannot be mixed with the charger of the lithium battery.

When using the charger! First of all, it depends on whether it is a lead-acid battery charger or a lithium battery charger, you can't mix the two chargers, otherwise the battery will be damaged, and secondly, look at the voltage, the charger voltage must be consistent, and the voltage will burn out the level if the voltage is too much.

Finally, look at the current, the current affects the charging speed, but the charger with a large current is better not to charge the battery with a small current, which is easy to damage the battery.

The current charger has overvoltage, overload protection, and full of automatic power-off function, but random use will still damage the battery, and even cause ** or fire, so be careful to use.

You can charge it, but you can't charge it! Because the voltage of a 72V22Ah battery is 86V to fully charge, a charger with an output voltage of 86V is required to fully charge. As for the output current of the charger, it only determines the speed of charging.

A 72V20A charger can charge a 72V22A battery. However, it will take a little longer to fully charge.

It's all lead-acid batteries, that's no problem, if it's all calculated as full, the charging time will be longer than an hour, and there is no difference in others

If your previous car's battery pack was also 72v, you will be fine with this charger. The premise is that the battery type must be the same, if it was a lead-acid battery before, it will not work if it is replaced with a lithium battery now.

Summary. Equipped with a charger with a nominal value of 72v30ah.

According to the specification, the initial charge: 1 7 1 14 of the rated capacity, normal charging: 1 7 1 5 of the rated capacity, the maximum charging voltage of a single grid is, so the maximum charging current should be 150Ah 5 = 30A, and the maximum charging voltage =.

The best charging current of lead-acid battery is one-tenth of the rated capacity of the battery, and the best charging current of the battery with a capacity of 32 A is ampere, and the charging voltage is the charger with the output voltage DC and output current ampere.

Can a 72v23ah battery be used with a 72v4a charger?

It can't be used for a long time, and it's rare to use it once.

How many amps of charger should I use?

Buy it according to the original match.

How big to buy? The best charging current of lead-acid battery is one-tenth of the rated capacity of the battery, and the best charging current of the battery with a capacity of 32 A is ampere, and the charging voltage is the charger with the output voltage DC and output current ampere.

Can you be specific?

Select the charger parameter voltage range.

Equipped with a charger with a nominal value of 72v30ah. According to the specification, initial charge: 1 7 1 14 of the rated capacity, normal charge:

The rated capacity of 1 7 1 5, the maximum charging voltage of a single grid is, so the maximum charging current should be 150Ah 5 = 30A, and the maximum charging voltage = . The best charging current of lead-acid battery is one-tenth of the rated capacity of the battery, and the best charging current of the battery with a capacity of 32 A is ampere, and the charging voltage is the charger with the output voltage DC and output current ampere.

Electric car.

A: Yes.

The matching of the charger and the battery, mainly the voltage parameters, in addition, if you want to charge efficiently, the maximum output current of the charger should be large enough.

Expansion: In other words, the charger can be used as a power source, the battery as a load, the charger is equivalent to 220V alternating current at home, the charger with different currents is equivalent to the 220V of the air output of different currents, such as the 5A air opening of 220V, to light a small light bulb, there is no problem at all, but if you go to a few kilowatt induction cooker, it may not work.

As another example, take the Type-C port power adapter of a notebook as an example, the 65W power adapter can charge a high-power device like a notebook, and it can also charge a low-power mobile phone, without any problems.

So you don't have to worry at all, as long as the voltage of the charger is the same, and you use a higher power charger to charge, the heat dissipation performance will be better and safer.

No, it doesn't. The current error is too large, and the battery will be inflated or even burned out. Chargers less than 30Ah can consider charging 20Ah batteries.

The charger voltage must match the battery voltage, the voltage is low and cannot be charged, and there is no current circuit in the cover bend, and the voltage will be charged with high current, resulting in the battery voltage rising and damaging the battery.

In fact, the 72-volt battery is 6 pieces of 12-volt series, and the voltage is in the volt when each is fully charged, then 6 is 81 volts, the charger is selected to see the voltage first, which is the key element, the second look at the current, the output current is large and the charge is fast, it is best to charge the battery with one-tenth of the capacity current, the effect is the best.

72v20ah battery:

Generally speaking, if the electric vehicle is equipped with a 72V20AH battery, it will generally be equipped with 600W, 1000W, 1500W and other types of motors. If the vehicle is equipped with a 600W motor, its average speed is generally around 40km h.

By calculation, we can get the average current size of the uniform speed for the motor power voltage), and the theoretical driving time is the battery capacity.

average current), while the theoretical range is about 95 kilometers (theoretical driving time * average speed of the vehicle).
