UPS battery expansion, how to allocate batteries for UPS

Additional batteries can be added to expand the capacity.

Ordinary multimeters cannot directly test the internal resistance of the battery. You can test it by indirect methods. For example:

Connect a resistor to the battery, and calculate the internal resistance of the battery by testing the voltage or current on the resistor.

It can be combined with 4 groups, but the original battery must be replaced with a new battery, the principle of UPS battery distribution is to use the same manufacturer of the same batch of batteries, because the battery will be used for a period of time after internal resistance, capacity differences, the use of different batches of batteries will reduce the overall life of the battery pack, and it is not very good for UPS.

The battery cannot be increased indefinitely, and the battery cannot be fully charged if the capacity of the internal rectifier of the UPS is exceeded.

2.Unmeasurable.

1.It's best not to add a battery pack, the reason is that the old and new batteries can't be mixed, and the 1000VA UPS rechargeable version is relatively small, and the battery is too much to charge.

2.The general multimeter side cannot be used to resist the internal resistance of the battery.

Available upon request.

It is possible to increase the battery, but it is not recommended! It is not recommended to mix old and new batteries!

How can the internal resistance of a single battery not be measured with a universal multimeter?

1. Consultation of questions.

Total load power p total (W), backup time (t).

Usefulness of UPS: Small, medium and large computer rooms?

2. Calculation Method.

The number of v-cell cells n:n=v 12 The number of 2v-cell cells is 6n2, and the battery working current i:i=p total v

3. Actual battery capacity c: c=i t kh

For example, if the power supply standby time is 4 hours with a power of 1kva, and the model of Crestec UPS is HP9101H, V=36V, then:

n = 36v 12v = 3 knots.

i=1000va÷36v=28a

c=28a×4h÷

The dosage of the battery can be selected from 100Ah group of 3 cells, or 65Ah two groups of 6 cells, and the results of the selection are deviated, which depends on the user's needs and cost considerations.

Note: The common capacity specifications of 12V batteries are 7ah, 17ah, 24ah, 38ah, 65ah, 100ah, 200ah, etc.

Ask him what the load is and how much power up he wants to match. How long is the backup time, and then it's good for the acid battery, power Battery voltage Number of battery blocks Single voltage * power factor = backup time.

1.Load power, what kind of load.

2.Whether the mains is 380V or 220V, and how many V is the load voltage.

3.How much backup time.

4.Installation environment location.

Ask him what type of load and how much power it has.

How long to backup.

Burke batteries** have a computational formula.

It depends on how long the customer's backup time is and how much power to bring.

To give you a little knowledge about UPS maintenance, who told you to "charge" once in three months, in the process of your use, it has been in a state of charging, proper discharge will be good for the battery, generally three months to carry out a discharge.

1) The use environment of UPS should pay attention to good ventilation, which is conducive to heat dissipation and keep the environment clean.

2) Do not bring inductive loads, such as money counters, fluorescent lamps, air conditioners, etc., to avoid damage.

3) The output load of UPS is controlled at about 60% is the best, and the reliability is the highest.

4) The UPS load is too light (such as 1000VA UPS with 100VA load) may cause deep discharge of the battery, which will reduce the service life of the battery, and should be avoided as much as possible.

5) Proper discharge, which is helpful for the activation of the battery, such as long-term non-stop mains, should be artificially disconnected every three months with UPS load discharge once, which can prolong the service life of the battery.

6) For most small UPS, turn on UPS when you go to work, avoid starting with load when you start up, and turn off UPS when you get off work; For the UPS in the network room, since most of the network works 24 hours a day, the UPS must also run around the clock.

7) The UPS should be charged in time after discharge to avoid damage to the battery due to excessive self-discharge.

1. When you choose UPS, you should consider whether the unit voltage is 220 or 380V.

Different brands of K UPS are usually 75%, 80%, 90% of the effective power, that is, 3750W, 4KW maximum. The power of the large model is about 10k 8000w-9000w, and it depends on what brand of UPS. You either choose two sets.

3. A set of UPS will bring you up the 9600W load, which is usually three orders of 15K 12kW on the market, but it must be 220V when the input 380V output.

4. What brand of 5k did you say, 12 sections don't have this configuration! APC 5K 3750W4 cells, you 12 cells are 3 groups, why do you configure a larger battery. This thing is suitable.

Emerson's UPS 5K output power requires 1 group of 16 knots.

Of course, 5kva is not enough for 9600w. At least 15kva UPS....You're going to have two hours on your side.

It is recommended to use two sets of 12V100Ah batteries, and the main engine is Shante 3C15KS....Details can be added to my buckle 1 1 9 5 3 9 2 9 9

Take the UPS of the Emerson ITA 16KVA (model number UHA3R-0160L) as an example:

Battery 12V 32 cells per group, 9600 384=25A, 2 hours backup: 25*2*, it is recommended to configure 32 12V 75Ah batteries.

There are the following rules:

The number of battery cells is determined by the UPS host, the UPS host is selected according to the load power, the battery cells are selected according to the host model, the battery capacity is selected according to the backup time, the empty opening capacity is selected according to the working current, and the cable diameter is selected according to the empty opening capacity.

How can a 5K UPS be able to afford a load! I don't think you need these 12 batteries! According to the backup time you need, we will configure the appropriate host and battery pack for you. UPS solution expert - Shenzhen Zhongda Power Technology.

Hello landlord, I am a professional UPS power supply. We'll be happy to answer for you. 5kva=4kw。

The maximum power of the equipment in your computer room is 9600W, so you have to configure at least one 9600W, but there is no 12KVA model in the UPS line, so it is recommended that you configure 15KVA. The DC input voltage of the UPS host of 15VA is 192V. So you have to match 192 12 = 16 12v65ah batteries.

It can be delayed by 40 minutes to 50 minutes when fully loaded. According to the power of your equipment room, the delay can be about 1 hour. If you are satisfied, please adopt, if you still have questions, please continue to ask.

9600W, the minimum is equipped with 15kva UPS, with a few batteries depends on what brand UPS you are, 12 is definitely not good. If Shante is 15kva, it will take 16 batteries in a group, and if it is fully loaded, it will take 65ah batteries in 2 groups of 32 batteries.

Not enough, at least 15kva, if you think that the load will increase in the future, it is better to 20kva. The battery is not as many as you want to use, but it must meet the voltage. If you want to use 12V 65A, the backup time is two hours, that is 30 batteries, you can add Q451245871

Do you load the device 9600w? The UPS of 5kVA can only carry a maximum of 4000W load, which seems to be a little smaller, or is it not all your equipment?? Be clear.

6 monomers:

See: DL T5044-2004 Technical specification for DC system design of electric power engineering.

Beyond this range, it will definitely have to be changed.

1) Over-discharge makes the terminal voltage of the battery lower than the allowable discharge final voltage of the battery. For a 12V M-type lead-acid battery, the final discharge voltage is about one.

2) In the UPS battery pack, the terminal voltage difference between the battery cells is more than 1V.

Charging operation, the initial charging current of the battery is generally according to the specified value in the manual, or according to the rated capacity of 1 10 current to carry out the base cavity.

1) Float charging. ** type battery pack is a long-term parallel connection on the charger and load line, as a backup power supply mode of operation. Under normal circumstances, floating charging is used, and the voltage of the single battery is controlled relative to the 2V battery), and the change of floating charge voltage is regularly observed and recorded.

If the voltage of the single battery is low, it means that the battery is not charged enough and the capacity is not enough, so attention should be paid to tracking.

2) Equalization charging. The so-called balanced charging is to connect each battery cell in parallel and charge it with a uniform charging voltage. If there is a backward battery in the floating charging process of the battery pack (the front side of the single voltage cavity is lower, relative to the 2V battery), or after 3 months of floating charging, it is advisable to carry out the uniform charging process, and the single storage tank is controlled at 6 8h (note, the average charging time should not be too long), and then adjust back to the floating charge voltage value, and then observe the voltage change of the backward battery, if the voltage is still not in place, it will be charged again after two weeks.

Under normal circumstances, the voltage of the new battery pack will tend to be the same after 6 months of floating charge and average charge. The equalization charging current is generally selected or slightly less. For batteries with a rated voltage of 12V, the balanced charging voltage is generally selected.

K's different brands of UPS are usually 75%.

90% of the effective power is 3750W

4kw max. The larger model is 10k

The power of about 8000W-9000W depends on what brand of UPS. You Li Yuyuan either choose two sets.

3. A set of UPS will bring you up the 9600W load, which is usually three orders of 15K 12kW on the market, but it must be 220V when the input 380V output.

4. The 5k brand you said doesn't have this configuration in 12 sections! APC 5K 3750W4 cells, you 12 cells are 3 groups, why do you configure a larger battery. This thing is suitable. Ai destroys Dou Merson's UPS

Output power. 1 set of 16 knots is required.

Your question is a bit bull-headed and bad-necked. Go to A-ri-ba-ba. Harvest. Electric shop.

Chuangren Technology. Find me to help you configure.

You're not thinking about it all.

The UP of 6kVA is very different in the selection of the number of battery blocks, that is, the requirements for the battery voltage.

First of all, I don't count, Wang Xuanyi just said.

Some are 12V*4 voltage, some are 12V*16 voltage, different UPS models, choose different number of electric trap stove pools and current, which is commonly referred to as ampere.
