TotalEnergies Coolelf EV – Premium Coolant for Electric Vehicles with Reduced Conductivity
TotalEnergies Coolelf EV is a ready-to-use premium coolant for battery electric vehicles (BEV), based on high-purity ethylene glycol and ultra-pure water. Free from 2-EHA, nitrites, borates, and amines, it uses organic acid technology (OAT) corrosion inhibitors. With reduced electrical conductivity, it provides excellent corrosion protection, minimizes short-circuit risks, and ensures long service life for EV cooling systems.
Product Advantages
• Ready-to-use mixture with ultra-pure water – no mixing required
• Specially designed for the needs of battery electric vehicles (BEV)
• Excellent corrosion protection for aluminum, steel, stainless steel, cast iron, and non-ferrous metals
• Compatible with common elastomers and thermoplastics used in EV cooling systems
• Reduced and stable electrical conductivity: 96 μS/cm (25°C) / 188 μS/cm (60°C)
• Minimizes short-circuit risks and hydrogen generation through electrolysis
• Compensates aluminum CAB brazing flux for improved material compatibility
• Maintenance-free due to stable inhibitors
• Environmentally friendly through carefully selected additives
Typical Applications
• Cooling systems of battery electric vehicles (BEV)
• Suitable for applications requiring reduced conductivity
