According to Tesla, your car can release smoke while charging because the charging process causes the battery to heat up, which can break down the chemicals and release smoke. So, technically, it''s a normal occurrence. But if the fog emitting from your Tesla is becoming excessive and has a strange odor, then there''s more than meets the eye.
It uses photovoltaic power to generate electricity and stores it in energy storage batteries. The energy storage batteries supply the power to the charging pile when necessary.

The fire protection challenge with lithium-ion battery energy storage systems is met primarily with early-warning smoke detection devices, also called aspirating smoke detectors (ASD), and the release of extinguishing agents to suppress the fires.
The energy storage system was installed and put into operation in 2018, with a photovoltaic power generation capacity of 3.4MW and a storage capacity of 10MWh. The explosion destroyed 0.5MW of energy storage batteries. It is understood that the lithium-ion battery cell supplier of the energy storage station is LG New Energy.
And the fire and explosion of energy storage stations have certain characteristics, mainly including: the types of accident batteries are mostly ternary lithium-ion batteries, and most of them occur during charging and rest periods.
Upon reaching the ceiling, the smoke disperses radially, then descends vertically. This process leads to an increase in thickness, ultimately causing the smoke to spread to the external environment through the exits located on both sides of the energy storage container (Long et al., 2022).
Understanding what chemicals are released when a lithium-ion battery emits smoke requires examining the specific substances that are generated during thermal runaway and combustion. Hydrogen fluoride is a toxic gas released during the thermal decomposition of lithium-ion batteries.
Furthermore, compared to heating coils, heating rods induce greater production of combustible gases during battery TR. As SOC increases, the intensity of LIB thermal runaway escalates while the energy threshold for initiating TR decreases. Gao et al. (2019) investigated the thermal characteristics of LIBs at various charge and discharge rates.
