The coolant and the cooling fan strive to maintain the battery temperature. It is chiefly made up of water, refrigerants, and ethylene glycol. It flows through the tubes and plates surrounding the battery to absorb the heat and dissipate it through the radiator or heat exchanger. Collectively, the system thus formed can make a little noise.
Some of the most common sounds include banging, clunking, popping, or thumping noises. These noises can be caused by a variety of factors, including the rapid expansion and contraction of materials as they heat and cool during the charging process.
This swelling is directly proportional to charging speed; hence, you are more likely to hear the thunk sound at level 3 stations. The metal sheet around the battery pack is often responsible for this noise as it flexes under the battery pressure. Read: How Much Do Electric Car Batteries Cost in 2022? 4. The Noise Might Be Coming From the Charger
When a battery is rapidly charged, it generates a significant amount of heat, which causes the metal components to expand. As the components cool down, they contract back to their original size, causing a banging or clunking noise.
In most cases, the sound occurs at the contactor of the charger as dust and debris accumulate on it. When high-voltage current flows, vibrations arise in the improperly seated charger, causing constant noise. However, the accumulation of dust is neither harmful to EVs nor does it hamper the charging process.
However, it is worth mentioning here that if you opt for the low levels of charging, i.e., 1 and 2, you can see a decline in the noise. The battery will not heat up faster, keeping the fan speed and coolant flow rate at a minimum. As for the noise coming from the charger, yes, you can get rid of it.

Get PriceWhen coolant starts circulating the batteries during charging, several noises can be generated—though they are not muchly noticeable compared to those coming from the fan. The most detectable sounds come from the flow of the coolant itself and the pump responsible for the flow, making a mix of splashing and mechanical sounds.
Get PriceThe Tesla Powerwall only makes noise when the cooling system is engaged, and frequently, this is a result of high energy use for an extended period of time. In order to prevent this, try to limit how much electricity you are using at a time, so the battery isn''t working as hard to keep up.
