Large Local Currents in a Lithium-Ion Battery during Rest after …
While the lithium that plates on graphite during fast charging affects battery safety, so do the internal ionic currents that can occur when the battery is at rest after charging. These currents are difficult to quantify; the external current that can readily be measured is zero.
Internal Currents in Lithium Batteries after Fast Charging
Researchers have long known that high electric currents can lead to "thermal runaway"—a chain reaction that can cause a battery to overheat, catch fire, and explode. But without a reliable method to measure currents inside a resting battery, it has not been clear why some batteries go into thermal runaway when an EV is parked.
What is the Recommended Charging Current for a New Lead Acid Battery?
The charging current should be a fraction of the battery''s capacity, typically around 10-20% of the battery''s amp-hour rating. The charging voltage should also be adjusted according to the battery''s temperature, as higher temperatures require lower voltages to prevent overcharging.
