As they age into the seventh and eighth year of service life, the cooling fan may need to be replaced in order to maintain battery health and overall vehicle fuel economy. If thermal management does not optimally fulfil its function, there is also a risk of premature aging of the battery. It is constantly checking the traffic around you and the road ahead, on the alert for potential accident risks. It influences the control strategies of the ESP (Electronic Stability Program), the all-wheel drive, and the electronically controlled rear-axle differential lock. When defining the electrification strategy, it was clear from the outset that all essential components would be developed in Affalterbach.
Liquid coolants have higher heat conductivity and heat capacity (ability to store heat in the form of energy in its bonds) than air, and therefore performs very effectively and own advantages like compact structure and ease of arrangement. As a result, the passive air-cooling technology has lost its popularity. For effective direct immersion cooling, a dielectric fluid must have a high density, high thermal conductivity, high specific heat capacity and low viscosity. Temperature management is optimized between components such as the battery, the HVAC system (heating, ventilation, and air conditioning), the electric motor, and the inverter. Belt-driven starter-alternator as standard. It is also more effective at removing heat from the battery, but it requires more energy to control the battery's temperature.
