Technological Path for Pure Electric Vehicles (BEVs) to Replace Hybrids and Internal Combustion Engine (ICE) Vehicles
In our last blog, we discussed Development Progress and Future Predictions for Major Foreign Hybrid vehicle Manufacturers. Today we are discussing the transition from ICE vehicles (fuel-based) to plug-in hybrid electric vehicles (PHevs) and ultimately to battery electric vehicles (BEVs) . This change is driven by a combination of technological advancements, policy mandates, cost reductions, and infrastructure scaling. Globally and in China, this path follows a "bridge" strategy: hybrids (PHEVs and non-plug-in HEVs) serve as an intermediate step to reduce emissions and ease infrastructure demands, while BEVs represent the long-term zero-emission goal. Key enablers include falling battery costs (from ~$132/kWh in 2022 to projected $60/kWh by 2034), improved energy density (e.g., via lithium iron phosphate or LFP chemistries), and ecosystem integration (e.g., vehicle-to-grid tech).
China leads this shift due to aggressive state-led policies since the mid-2000s, viewing EVs as a "leapfrog" technology to bypass ICE dominance by Japan and Europe. Globally, adoption is uneven: Norway and Europe are BEV-heavy, while the US lags due to policy uncertainty. Below, I outline the technological roadmap and key milestones, drawing on market data and projections.
Technological Roadmap
The path can be segmented into three phases:
- Foundation (Battery & Drivetrain Innovation),
- Integration (Infrastructure & Software),
- Dominance (Scaling & Optimization).
This applies to both China and global contexts, with China accelerating faster due to vertical integration (e.g., 75% of global battery R&D papers from 2020-2024).
| Phase | Key Technologies & Developments | China-Specific Advances | Global Context |
| Foundation (2010s-2025)Battery & Drivetrain | -Lithium-ion batteries dominate (NMC/ LFP chemistries ); costs drop 89% (2010- 2021 ). -BEV range improves from <200 km to 400+ km. -Hybrids bridge with ~50-100 km electric range. | - LFP batteries (safer, cheaper) reach 30% global share; BYD/CATL lead production. - Sodium-ion pilots for budget EVs (<$10k models). | - NCA/NMC focus in US/Europe for higher density. - Solid-state batteries (SSBs) at lab scale (TRL 3-4). |
| Integration (2025-2035) Infrastructure & Software | - Fast-charging (350 kW+) and swapping stations scale. - Software-defined vehicles (SDVs) with OTA updates for efficiency. - V2G for grid stability; AI for predictive maintenance. | - 18M+ charging ports by 2025; battery swapping (NIO) for <5-min refuels. - Huawei/Xiaomi integrate ADAS/karaoke in EVs. | - EU/US aim for 1 charger per 10 EVs by 2030. - SSB commercialization (first vehicles 2025-2027). |
| Dominance (2035+) Scaling & Optimization | -SSBs enable 800+ km range, 10-min charges. -Recycling/reuse for circular economy; mineral- efficient chemistries (e.g., Na-ion). - Fleet electrification (trucks/buses) via modular platforms. | - 80%+ NEV sales; REEVs (extended-range PHEVs) phase out for pure BEVs. - Dominance in exports (69% global EVs made in China by 2024). | - BEVs >80% sales; hybrids <10%. - Global fleet parity (EVs surpass ICE stock by 2040). |
Key Time Nodes for Replacement
Replacement is measured by new sales share (faster shift) and fleet stock (slower, as ICE lasts 15+ years). Data combines IEA STEPS/APS scenarios, BloombergNEF, and S&P Global projections. China hits milestones 5-10 years ahead of global averages due to subsidies (e.g., CNY 20k incentives) and mandates (20% NEV by 2025).
Global Timeline:
- 2025: BEV + PHEV sales reach 25% of new vehicles (22M units); hybrids peak as bridge tech. ICE still >70%; battery costs ~$80/kWh enable price parity in Europe/Norway.
- 2030: BEV + PHEV at 40-55% sales (43-60M units); BEVs ~81% of EVs (25M units). Hybrids ~20-30%; ICE <50%. Norway: 100% zero-emission sales; EV fleet surpasses ICE. EU bans new ICE sales.
- 2035: BEV + PHEV >70% sales; BEVs dominate (>60%). Hybrids <20%; ICE <20% sales, fleet peaks/declines. Global EV fleet > ICE in key markets (e.g., Germany 2039).
- 2040+: BEVs >80% sales/fleet; hybrids <10% (phased out via mandates); full ICE replacement in fleets.
China Timeline (NEV = BEV + PHEV + FCEV):
- 2025: NEVs 50%+ new sales (overtaking ICE); BEVs 60% of NEVs, PHEVs 40%. EVs cheaper than ICE; hybrids grow but BEVs lead via LFP affordability.
- 2030: NEVs 56-80% sales; BEVs >50% of NEVs (fleet 70% ICE shrinks to 41% sales). PHEVs peak ~30-40%, then decline; EV fleet surpasses ICE (2033). Fuel economy standards (3.3L/100km fleet avg) force hybrid phase-out.
- 2035: NEVs >90% sales; BEVs 70%+ of NEVs. Hybrids <10%; ICE <10% sales, fleet <50%.
- 2040+: Near-100% BEV dominance; hybrids/ICE marginal (e.g., rural fleets).
Key Drivers and Challenges
- Enablers: Battery innovation (China's 80% cell production) and policies (e.g., China's Dual Credit mandate, EU 2035 ICE ban) accelerate BEV uptake. TCO for BEVs already lower than ICE in China/Europe; global parity by 2026-2028.
- Challenges: Hybrids persist longer in the US/China (e.g., REEVs for range anxiety); infrastructure gaps (9x charger growth needed globally by 2030); mineral supply (China controls 60% lithium processing).
- China vs. Global: China's ecosystem (e.g., BYD's full-stack integration) enables 2-3x faster BEV scaling, exporting to emerging markets. Globally, hybrids delay full BEV dominance by 5 years in slower markets like the US.
Conclusion:
This path positions BEVs as the endgame, with hybrids as a 10-15 year bridge. Projections assume continued policy support; reversals (e.g., US subsidy cuts) could delay by 2-5 years.
Specifically points:
- Europe & North America is with grid insufficiency in rural and remote areas,
- USA customers preference to large SUV and Pica truck, BEV need high cost to cater for such demand,
- Japan and ASEAN countries still rely on HEV with slow conversion,
- Geopolitical factors play key influence to battery raw material (Lithium, cobalt, nickel) supply chain risk.
