| | JUNE 20228I ndia is the 5th largest car market in the world & has the potential to become one of the top three in near future with 400 million customers in need of mobility solution by 2030. The country needs a transportation revolution. The transition to electric mobility is a promising global strategy for decarbonizing the transport sector. India is among a handful of countries that supports the global EV30@30 campaign, which aims for at least 30 percent new vehicle sales to be electric by 2030. To meet this target, Interconnects technologies from a key spoke in the wheels of EVs deployment. Interconnects can be mainly categorised into Power Interconnects, Signal Interconnects apart from the other segments. Power Interconnects consists of molded Busbars, phase busbars & motor stator busbars. The Signal Interconnects include the power connectors, modules and assemblies & power connection systems, the main function of all these Interconnect solutions is for carrying current, signal to and from the various vehicle systems, like motor, battery, ECU, cooling system, steering system, and more. In the design, development & manufacturing of the above various interconnect solutions, various challenges are faced by designers and the engineering faternity. We can focus on some of the considerations in the battery interconnects. For any part engineers need to consider the most important ascpects Form, Fit & Function into their design.Function:Electrical Performance:1. Interconnects must be designed in a way to have shortest current path from most +VE to most -VE. This is to minimize Joule heating effect of Current Collector Assembly.2. Interconnects must be able to carry specified continuous & Peak current.3. Battery Interconnect System to must be designed to have no resistance imbalance across conduction path. To achieve this, Current Collector Assembly must be designed to have uniform current density.4. Battery Interconnect System needs to be kept under specified max. Temperatures and as much as possible, it needs CHALLENGES IN DEVELOPING INTERCONNECT TECHNOLOGIES FOR EVs & HOW TO ADDRESS THEMBy Amit Ingale, Managing Director, Interplex Electronics IndiaAmit Ingale, Managing DirectorINDUSTRY INSIGHTS
