What is the peak power of Tesla's 85 kWh battery pack?

In summary, there is not a general conversion for power rating of batteries. It depends on the design and can vary between batteries with the same energy capacity. For example, the Tesla 85 kWh battery pack has a peak power of 270 kW for the Model S.

I have a pretty general question. If you look at battery packs, for example the Kolibri one below:

http://www.kolibri-ag.com/en/kolibrirack1.html

it's stated that the connection power can be up to 24 kW with storage up to 45 kWh.

Does this mean that power can be sourced at 24 kW from the battery for about 2 hours (1.875 h)?

Then thinking about Tesla's batteries, the 85 kWh battery pack for example, what is the power rating of that battery pack?

Is there a general conversion or does it depend on use?

Yes, exactly.

There is not a general conversion. It depends on the design of the battery itself. You can have two batteries with identical energy, but different power, and vice versa.

The peak power (or rather the minimum peak power) that the battery can deliver can be estimated... How much does the motor draw flat out?

EDIT: Depends on the model but appears to be 270kW for the 85kwh Model S.

What is a battery?

A battery is a device that stores chemical energy and converts it into electricity. It is made up of one or more electrochemical cells, which consist of two electrodes (a positive and a negative) and an electrolyte solution.

How does a battery work?

When a battery is connected to a circuit, a chemical reaction occurs between the electrodes and the electrolyte solution. This produces a flow of electrons, creating an electrical current. The battery will continue to produce this current until the chemicals inside are depleted.

What is the difference between battery power and energy?

Battery power refers to the rate at which a battery can supply energy, measured in watts. Battery energy, on the other hand, refers to the total amount of energy that a battery can store, measured in watt-hours.

What factors affect battery power and energy?

The power and energy of a battery can be affected by several factors, such as the type of battery (e.g. alkaline, lithium-ion), temperature, age, and the amount of current being drawn from the battery.

Can batteries be recycled?

Yes, batteries can be recycled! The materials used in batteries, such as metals and plastics, can be reused to make new batteries or other products. Properly recycling batteries also helps to prevent hazardous chemicals from entering the environment.
