How many cells do 24v30a lithium batteries need?

Introduction The number of cells required for a 24v30a lithium battery varies depending on the type of cells used. Taking a lithium iron phosphate battery as an example: the total voltage is 24 V and the cell voltage is 3.2 V.

How many cells do 24v30a lithium batteries need?

The quantity required varies depending on the type of battery cells used. Take a lithium iron phosphate battery as an example: the total voltage is 24V and the cell voltage is 3.2V, then the required number of strings is 24/3.2 = 7.5. , which requires only 8 batteries are connected in series, the voltage is 3.2*8 = 25.6 V; the capacity is 30 Ah; if the capacity of a single cell is 30 Ah, then one series is enough, that is, the total number of batteries. is 8. If the capacity of a single cell is 10 Ah (for example, other capacities can be deduced by analogy), then 30 Ah/10 A = 3 strings are required, i.e. that a total of 8*3 = 24 cells are needed.

How many kilometers can a 30 Ah battery travel?

A 48V 30 Ah lithium battery can travel 55 kilometers.

Cold starting current is the minimum current that can be obtained fromhas a specific meaning under the conditions of -17.8℃ and -28.9℃. This indicator relates the starting capacity of the battery to important variables such as engine displacement, compression ratio, temperature, starting time, technical condition of the engine and electrical system, as well as voltage minimum used for starting and ignition.

Reserve capacity is the approximate length of time the car can operate at night with the battery on and providing the minimum circuit charge when the charging system is not operating. It can be specifically expressed as: a fully charged 12V. battery, under 25℃ conditions, discharge it at a constant current of 25A until the voltage across the battery drops to 10.5V. The discharge time.

What is a lithium battery:

Lithium battery is a type of battery that uses lithium metal or un lithium alloy as positive/negative electrode materials and which uses non-aqueous electrolyte solution materials. Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, M. S. Whittingham proposed and began studying lithium-ion batteries.

As the chemical properties of lithium metal are very active, the processing, storage and use of lithium metal have very high environmental requirements. With the development of science and technology, lithium batteries have become mainstream.

Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth generation product of rechargeable batteries, lithium metal batteries, was born in 1996. Its security, its specific capacity, its self-discharge rate and its performance-price ratio are better than those of lithium-ion batteries.

How far can a 70 V30 Ah lithium battery operate?

200 kilometers. Judging from the battery life of some current models, normal vehicles with two sets of 30 Ah batteries can travel around 200 kilometers. The range of lithium battery electric vehicles is related to the configured capacity of the lithium battery, that is, the larger the configured capacity, the longer the mileage can be.

To determine the distance traveled by a 70V30Ah lithium battery, the following factors should be considered:

1. Electric Vehicle Power Consumption: The power consumption of different vehicle models or conditions. is different. The power consumption of electric vehicles is generallyent expressed in terms of energy consumption per 100 kilometers (Wh/km) or energy consumption per 1,000 kilometers (kWh/100 km). Depending on the vehicle model and driving conditions, the energy consumption of an electric vehicle can be estimated.

2. Efficiency of electric vehicles: Different models of electric vehicles have different drive system efficiencies. The driving efficiency of electric vehicles is usually expressed as a percentage. Higher driving efficiency means more efficient battery use and longer range.

3. Battery Capacity: 70V30Ah means the battery rated voltage is 70V and the capacity is 30Ah. The rated energy (Wh) of the battery can be obtained by multiplying 70V*30Ah.

Based on the above factors, we can estimate the battery life. Suppose that the energy consumption of a vehiclee electric is 15Wh/km and the driving efficiency is 90%. Then the rated energy of the battery is 70V*30Ah=2100Wh. We can get the driving mileage by the following calculation:

Driving mileage = battery life Energy / (power consumption * driving efficiency)

= 2100 Wh / (15Wh/km * 90%)

≈ 15 km

The calculation above is only an estimate. Actual mileage will be affected by many factors, such as driving speed, road conditions, temperature, etc. Actual mileage may therefore vary. If you want to know the actual range of a specific electric vehicle, it is recommended to refer to the official model data or consult the respective car manufacturer.
