As the global push toward vehicle electrification accelerates, the entire new energy vehicle (NEV) supply chain is under mounting pressure. Automotive-grade MCUs (Microcontroller Units), IGBTs (Insulated Gate Bipolar Transistors), and BMS (Battery Management System) chips have emerged as critical components in Tier 1 suppliers’ procurement strategies. Any disruption or delay in these components directly affects the production and launch timeline of electric vehicles.
1. Tier 1 Suppliers Signal Aggressive Expansion
From late 2024 into early 2025, leading Tier 1 suppliers—such as Bosch, Continental, ZF, and DENSO—have significantly increased their chip procurement volumes. Key drivers include:
● OEMs accelerating NEV platform development, increasing the need for integrated control and power modules;
● Recovery in export markets, prompting Tier 1s to scale capacity;
● Global policy incentives, particularly in Europe and China, boosting demand and prompting forward inventory planning.
Recent data shows many Tier 1 suppliers have already locked in MCU and IGBT orders for the first half of 2025, with procurement cycles shifting 1–2 months earlier than in prior years.
2. Lead Time Trends for Automotive-Grade Chips
■ MCU (Microcontroller Unit)
After relative easing in 2023, automotive-grade MCU lead times are rising again due to increasing vehicle system complexity:
● High-end MCUs from NXP, Renesas, and Infineon (used in EV drive units and ADAS) now show lead times of 26–32 weeks.
● Mid-to-low-end MCUs for body control and displays remain at 18–24 weeks, but centralized demand creates sudden shortages.
■ IGBT Modules
IGBTs are core to EV inverter systems and continue to face strong global demand:
● Domestic Chinese brands like StarPower and BYD Semiconductor are seeing surging demand, with spot shortages for several models.
● International suppliers such as Infineon and onsemi show lead times of 30+ weeks for automotive-qualified modules, with limited short-term substitution options.
■ BMS Chips
BMS components show structural tightness across several categories:
● Voltage monitoring ICs (e.g., from ADI and TI) now face lead times exceeding 28 weeks;
● Power and signal processing chips show erratic availability, with some parts at temporary risk of supply disruption.
3. Stocking Strategy and Supply Chain Recommendations
To mitigate risks associated with rapid EV market expansion, Tier 1 suppliers and OEMs are advised to adopt the following strategies:
■ Proactive Procurement Planning
Secure critical chips 6–9 months in advance, especially MCUs and IGBTs. Where possible, establish Long-Term Agreements (LTAs) with suppliers to ensure priority delivery and price stability.
■ Diversified Sourcing Channels
Leverage domestic authorized distributors and flexible supply partners to strengthen spot-sourcing agility. Evaluate second-tier domestic IC vendors for potential replacement or backup solutions.
■ Joint Development & Qualification
Engage chipmakers early in BMS or control system design for tailored solutions. Accelerate AEC-Q100 certification on alternative components to increase supply chain flexibility.
■ Strategic Buffer Inventory
Based on EV model SOPs (Start of Production), establish 3–6 months of buffer inventory for mission-critical components. Consider Minimum Required Operating Levels (MROL) for safety stock across ECU platforms.
