WK87291 details the requirements for low electrically conductive, fully formulated glycol-based coolants used in BEVs. The low conductivity requirement is to protect the batteries from shorting out in the event of a cooling system failure. These coolants will require non-ionic corrosion inhibitors.
These include performance and durability requirements for industrial batteries, electric vehicle (EV) batteries, and light means of transport (LMT) batteries; safety standards for stationary battery energy storage systems (SBESS); and information requirements on SOH and expected lifetime.
Performance and Durability Requirements (Article 10) Article 10 of the regulation mandates that from 18 August 2024, rechargeable industrial batteries with a capacity exceeding 2 kWh, LMT batteries, and EV batteries must be accompanied by detailed technical documentation.
Coolants need to be specifically designed for the unique characteristics of EVs. Work has begun on specifications for two types of EV coolants, a glycol-based coolant for fuel cell electric vehicle (FCEV), battery electric vehicle (BEV) and plug-in hybrid electric vehicle (PHEV), and a waterless coolant for BEVs.
So, maintaining battery at ideal conditions is necessary to prevent battery from deterioration. The ideal working condition for li-po batteries temperature ranges from 25 °C to 40 °C and should not exceed 50 °C as it harms the lifespan of the batteries .
Conversely, temperatures exceeding 40 ° C lead to reduced internal resistance, accelerated battery aging, higher self-discharge, and a shorter lifespan. When it comes to cooling methods, the paper mentions the use of dielectric coolant in direct cooling to prevent cell short circuits and facilitate efficient heat transfer.
The research thoroughly investigates the effects of temperature and indicates that the best normal temperature span for lithium-ion batteries lies between twenty-five to forty degrees Celsius, whereas the vehicle's working range is between −30 ° C and 60 ° C.
