However, for extreme conditions, single functional thermal fluids cooling may not be enough to control the battery temperature within the specified operating temperature range.
In addition, different battery types and BTMS applications need to operate in different or wider temperature ranges, which can be realized by functional thermal fluids. Some NFs can operate over a wider temperature range, so they can better meet the needs of different battery types and applications.
As a new type of fluid, functional thermal fluids mainly include nanofluids (NFs) and phase change fluids (PCFs), which have the advantages of high thermal conductivity and high specific heat, can effectively improve the heat transfer efficiency and temperature uniformity of liquid cooling system.
The most important aspect in the selection of suitable fluids is the ability to dissipate heat from the system in direct contact with the cells. Therefore, physical properties like specific heat capacity, thermal conductivity and viscosity are analyzed in laboratories.
Advanced EV Fluids to protect your EV’s transmission, and extend the life of the drivetrain system. Unlike cars with combustion engines, which require a multi-speed transmission, the e-motor in an electric vehicle produces a consistent amount of torque, almost regardless of RPM.
Castrol ON EV Thermal Fluid with advanced properties have been developed to enable improved battery thermal management in electric vehicles. It has superior properties to enable improved battery thermal management performance: Lower viscosity than conventional dielectric fluids such as transformer fluids that enable efficient heat transfer.
