As the battery is in a low-rate charging status, the battery thermal management system is capable of cooling the battery rapidly. When the battery temperature drops to below 50 °C, the charging rate of the battery rises to 2.12 C.

Customer ServiceAuthor to whom correspondence should be addressed. Electric vehicles (EVs) in severe cold regions face the real demand for fast charging under low temperatures, but low-temperature environments with high C-rate fast charging can lead to severe lithium plating of the anode material, resulting in rapid degradation of the lithium-ion battery (LIB).
When charging at low temperatures, it is recommended that the battery is first preheated to at least 15 °C. The self-generated heat of the battery alone is not sufficient to counteract the negative effects of low temperatures on fast charging.
Low temperature degrades battery charging due to the following two reasons. First, the deposition of lithium metal on the graphite electrode will occur when the battery is charged at low temperatures, causing loss of cyclable lithium and potential safety hazards .
Minggao Ouyang et al. found that at −10 °C, when the charging current reached 0.25C or the cut-off voltage reached 3.55 V, a signal associated with lithium metal could be observed on the surface of the anode. All the above results indicate that it is not suitable for direct fast charging of LIBs under low temperatures.
Under the very low temperature environments (from −20 to −10 °C), serious lithium plating occurs in the initial cycle of the battery, which leads to the consumption of recyclable lithium-ions at a very fast speed and causes the battery to quickly reach EOL.
Design of a novel adaptive framework for battery charging in cold environments. Impacts of battery temperatures on model parameters are experimentally identified. Number of charging stages and the associated transition conditions are adaptive. A trade-off between charging time and battery aging at low temperatures is achieved.
