Electrification is a top priority for vehicle manufacturers. Vehicles are increasingly equipped with advanced batteries to accomplish global environmental targets with eco-friendly vehicles, such as electric (EV), hybrid electric (HEV), or plug-in hybrid vehicles (PHEV). These new fundamental changes also bring some uncertainties in the vehicle development process, especially regarding battery reliability before introducing new electrified vehicles into the market. Validating batteries before vehicle implementation now plays a crucial role in the development cycle.
In this on-demand webinar, you will discover:
New uncertainty from electrification puts OEMs and suppliers at risk of new durability problems due to heavy battery packs. Most modern electric cars are 20 to 30% heavier than internal combustion engine (ICE) cars of comparable size and power output. A higher operational load causes more energy consumption, a smaller driving range, and damaging road load challenges. Additionally, electric vehicle batteries average one-third of the total vehicle weight, causing mass distribution challenges and durability issues in other locations. Siemens durability engineering solutions can help OEMs and suppliers solve electric vehicle battery durability issues.
Due to complex supply chain systems, OEMs push automotive battery manufacturers to validate batteries before vehicle implementation. Today’s EV battery manufacturers must meet essential performance requirements for durability, comfort, noise, vibration, and harness (NVH) in a short development time covering battery design, simulation, and testing. If they fail to meet these standards, the cost is very high and unacceptable. Additionally, hardware needs to acquire data during vibration testing, or shaker test, for further processing. Siemens testing solution combines data acquisition and shaker testing with single hardware, significantly reducing test and data post-processing time.
Test and validation engineers need to test their batteries against durability and reliability with correct test procedures in a very efficient way to prevent costly product recalls after bringing the product into the market. Siemens solutions enable battery design and testing to warrant reliable operation throughout the lifetime using real-life measurements and testing profiles to accelerate testing without over or under testing the battery unit. For example, OEMs can use fatigue damage spectrum (FDS) to compare qualification evidence of potential component suppliers. While automotive suppliers can classify different OEM test needs, standardize on test profiles, and use FDS to compare other specifications and design a single qualification test.
