For a typical 6f22-form factor battery it is something 2-20 ohm for a new battery at room temperature. It gets higher as the battery gets discharged, rises with discharge current and gets a bit lower for moderately elevated temperature (say, ~50C). The initial short-circuit current for such a battery is ~1 Ampere.
6 FAQs about [Lithium battery current limiting output]
What is the maximum voltage a lithium battery can charge?
There was an immediate voltage change when the high rate pulses were applied. The maximum current that could be applied to the cathodes, at the rated charging voltage limit for the cells, was around 10 C. For the anodes, the limit was 3–5 C, before the voltage went negative of the lithium metal counter electrode.
What are battery limit calculations?
The limit calculations take into account the health of the battery pack, internal resistance, battery temperature, and also enforce the maximum pre-set limits in the programmable battery profile for current draw at various temperatures. Values can be expressed in amps or kilowatts for automotive applications.
What is the maximum charge current to avoid a negative voltage?
For anodes, the maximum charge current to avoid a negative voltage was 3–5 C. Negative anode voltages do not necessarily mean that lithium plating has occurred. However, lithium deposits were observed on all the anodes after 5000 pulse sequences with 10 s pulses at ± 20 C.
What is the diffusion limit of lithium plating?
For the anodes, the limit was 3–5 C, before the voltage went negative of the lithium metal counter electrode. This introduces the possibility of lithium plating. Another issue is that the diffusion limited process could not be sustained through many of the high rate, 10 s pulses.
Do lithium particles grow in voltage transients?
There was no evidence of nucleation and growth of lithium particles in the voltage transients. However, it will be very difficult to reduce the resistance of the anode to the point at which the voltage does not go negative during high rate charging.
What happens if you don't have a reliable battery limit?
Failure to have reliable limits can allow the main control computer to draw too much current from the battery, causing the limits to suddenly dive. In order to respect the new limit, the main drive computer would be forced to reduce current, leading to a jerky or possibly dangerous driving experience.
