TE Connectivity announced the acquisition of EV charging inlet assets from Phoenix Contact, expanding its electric-vehicle charging solutions portfolio. The transaction strengthens TE's position across the broader e-mobility electrical ecosystem and complements its existing automotive relay and contactor portfolio. Expansion across EV charging technologies can strengthen supplier capabilities around high-voltage vehicle electrical systems and adjacent switching applications.
The shift towards battery-electric and plug-in hybrid vehicles is changing relay requirements from conventional low-voltage switching toward components capable of handling higher electrical loads. Panasonic’s range of automotive products include high capacity DC contactors and automotive relays for use in EVs, while Panasonic’s TF series of relays is aimed at automotive AC loads that include onboard charging as well as vehicle to load applications. This shift opens up opportunities for manufacturers who can design products that integrate electrical isolation, small form factor packaging and reliable switching capability. It is not only about manufacturing relays but developing architectures around battery, charging, and power distribution.
The IEA estimates that China produced about 16 million electric cars in 2025, representing nearly 75% of global electric-car production. The Chinese exports of electric cars also surpassed 2.5 million, while the exports from Southeast Asia and its sales saw a rapid growth. This provides for relay makers a huge local customer base in the form of OEMs and Tier-1 customers, along with exports. The competition will hence shift to volume manufacturing. Suppliers with established production and engineering relationships in China's automotive ecosystem are positioned to capture demand from both domestic and export-oriented vehicle programmes, thus shaping the Asia Pacific automotive relay market trends.
Electric-car sales in Southeast Asia more than doubled during 2025, with Vietnam, Indonesia and Thailand among the leading growth markets. The region is also becoming more important for automotive manufacturing as governments seek greater domestic production and supply-chain localisation. Indonesia, for example, is moving towards greater local production of EVs, while Thailand and Vietnam have developed sizeable electric-mobility ecosystems. This creates opportunities for relay suppliers beyond the established Japanese and Chinese markets. Component manufacturers can benefit from supplying both conventional vehicle programmes and new EV platforms as regional assembly capacity develops.
Modern vehicle electrical systems require higher functionality within increasingly constrained packaging environments. Panasonic's TC and TG relay families, for example, are designed for high-load switching in smart junction boxes, while the company's TM series combines a compact form factor with 35A capacity. This points to an important product-development direction: suppliers are competing not simply on current capacity but on the combination of current handling, dimensions, thermal performance, sealing and manufacturing compatibility. Such requirements favour suppliers capable of co-engineering components with vehicle electrical-system manufacturers.
India recorded 165,000 electric-car sales in 2025, up 75% from the previous year, while the number of electric models available increased from 33 to 45. At the component level, localisation is becoming strategically relevant as OEMs and suppliers seek shorter supply chains and greater domestic manufacturing. Mitsuba's May 2026 earnings briefing specifically highlighted plans to expand local procurement and production, establish local R&D capabilities and relocate production lines in India to strengthen competitiveness. For relay suppliers, India's expanding automotive production base therefore offers opportunities in both OEM supply and locally manufactured electrical components.

Australia offers a small yet advanced market due to vehicle imports, aftermarket requirements and vehicle electrification.
By relay type, high-voltage relays offer the strongest electrification-led expansion opportunity
PCB relays are expected to remain a leading relay category because they integrate directly with electronic control units, circuit boards and vehicle electrical modules. Such a design allows space-efficient architecture for vehicles along with switchability in the lighting, body electricals, comfort, and controls segments. The rise in the electronics content in passenger vehicles and commercial vehicles maintains the relevancy of these systems in traditional as well as electrified vehicles. This is due to the rise in the number of vehicles which are becoming electrified. According to IEA, there were almost 22 million cars produced around the globe in 2025, increasing by more than 25% year-on-year. As vehicle electrical architectures become more sophisticated, PCB-mounted switching components can address a wide range of compact electronic modules. Such developments will thus boost the Asia Pacific automotive relay market dynamics and trends in the long run.
High-voltage relays are positioned for strong expansion as battery-electric and hybrid vehicles increase across Asia Pacific. Electrified powertrains require specialised switching and isolation for battery packs, charging systems and high-voltage power distribution. Panasonic's automotive portfolio includes high-capacity DC contactors and relay solutions designed for EV-related applications, demonstrating supplier investment in this technology. The growth opportunity is reinforced by Asia Pacific's exceptionally strong EV manufacturing base. China alone produced around 16 million electric cars in 2025, accounting for nearly 75% of global EV production. Southeast Asia also recorded EV sales growth of more than 100% in 2025, with electric cars reaching nearly 20% of regional car sales. These trends are increasing demand for high-voltage switching and contactor technologies.
By vehicle type, passenger cars are anticipated to dominate recurring aftermarket demand
Passenger cars represent the broadest application base for automotive relays because each vehicle incorporates numerous electrical and electronic functions requiring switching components. Lighting, locking, comfort systems, safety electronics and power-management functions create recurring relay requirements across conventional, hybrid and electric passenger vehicles. The passenger vehicle manufacturing sector in the Asia Pacific region also helps to stimulate demand from the OEMs and Tier-1 suppliers. Another source of demand stimulus is the electrification of passenger vehicles. The IEA states that more than 20 million electric cars were sold worldwide in 2025, accounting for one-quarter of all car sales. This expanding installed base increases opportunities for relay suppliers across both conventional and electrified passenger-car architectures, thereby bolstering the Asia Pacific automotive relay demand.
Electric vehicles represent the strongest structural growth opportunity within the vehicle-type segmentation as Asian markets accelerate electrification. China produced approximately 16 million electric cars in 2025, while global EV production approached 22 million units, up more than 25% from 2024. China also recorded more than 13 million electric-car sales in 2025, with EVs accounting for almost 55% of new-car sales. Meanwhile, Southeast Asian EV sales more than doubled in 2025 to around 500,000 units, representing nearly 20% of regional car sales. Electrified platforms require additional high-voltage switching and power-management components, creating significant opportunities for relay and contactor suppliers.
By ampere, lower-current relays retain scale while high-current products gain strategic importance
The 5A–15A category benefits from the wide range of lower-load electrical functions incorporated into modern vehicles. Such relays can help facilitate the operation of many body-electronics and auxiliary functions without needing to meet the requirements associated with higher current switchings. The applicability is not limited to passenger cars and commercial vehicles with varying types of powertrains. The use of electronic control modules, lighting, lock mechanisms, and other electrically operated devices helps provide various opportunities for their usage. Therefore, lower current relays still remain commercially valuable, despite all efforts to electrify high-voltage vehicles, and thereby bolstering the demand of the Asia Pacific automotive relay market.
Relays above 35A have increasing strategic relevance as vehicle electrical systems handle higher loads and electrification expands. EV and hybrid architectures introduce demanding power-management requirements around batteries, charging equipment and electrically driven systems, increasing the need for robust switching components. The scale of electrification supports this transition: global electric-car production reached nearly 22 million units in 2025, while China alone produced 16 million electric cars, representing nearly three-quarters of global output. Higher-current products require stronger contact performance, thermal management and electrical endurance, creating opportunities for technically differentiated suppliers. Panasonic's automotive portfolio includes high-capacity switching products designed for electrified applications, illustrating the industry's movement toward higher-load solutions.
By application, established powertrain functions coexist with emerging electrification applications
Engine management modules remain an important automotive relay application because internal-combustion and hybrid vehicles continue to represent a substantial portion of Asia Pacific's vehicle fleet and production. Relay functions within these systems support electrical control and power distribution for engine-related components and auxiliary systems. The segment benefits from established automotive architectures, large installed vehicle populations and ongoing electronic integration. Although pure battery-electric vehicles eliminate conventional engine-management requirements, hybridisation and continued ICE vehicle production preserve the application base. Suppliers therefore continue to serve this established category alongside emerging EV applications. Importantly, the IEA notes that EV sales represented nearly 55% of new-car sales in China in 2025, indicating rapid electrification while also leaving a substantial non-EV vehicle base in the wider Asia Pacific market.
The Others category offers emerging opportunities as vehicle electrical architectures develop beyond traditional relay applications. The electrification process will introduce new demands related to batteries and electric drive systems, which will not always correspond to the existing classifications related to engine management, lighting, or locking systems. The magnitude of this shift is quite large: China made up 70% of global electric car production in 2025, whereas China, Europe, and North America collectively produced 95% of global battery production in 2023-2025. However, publicly available evidence does not provide sufficient quantitative data to definitively identify the Others category as the fastest-growing application. It is therefore more appropriate to describe it as an emerging opportunity rather than assign an unsupported growth ranking.
