Case Study
India is concentrating on ramping up two- and three-wheeler electric vehicle (EV) platforms. With lower additional costs from internal combustion engine (ICE) equivalents and very low running costs, customers can now choose a sustainable alternative to ICE vehicles. However, their drivetrain components were not originally made to comply with Indian environmental requirements, including thermal, vibration, and ingress protection requirements. Nhanz, with ample original equipment manufacturer (OEM) experience, front-loaded these requirements into their design and iterated different thermal combinations to create a practical drivetrain.
The major challenge with these systems is their very low cost of system manufacturing, which eliminates the facilitation of liquid cooling. A shortage of qualified automobile fans rules out the alternative of forced air cooling. Hence, suppliers are inclined to meet requirements with practical, natural airflow within the vehicle. This is aggravated by high grade roads and heavy vehicle loads, which increases the average dissipation loss in the system.
Nhanz worked out multiple inline thermal management systems to meet technical and cost requirements using the parameters from the challenges they faced. To consider a practical scenario, all peak ratings were checked after continuous ratings were stabilized. Simulations were performed to check multiple peak operations that a system could handle in sequence. With considerable effort spent in virtual validation in different scenarios, they developed a platform which worked, as per simulation, “first-time right.”
