ELECTRICALS & ELECTRONICS
Automotive electronics encompass a wide range of electronic systems used in vehicles, including engine management, battery management, ignition systems, lighting, and more. Modern electric vehicles rely heavily on power electronics for propulsion motor control and battery system management. Looking ahead, autonomous vehicles will depend on advanced computing systems, extensive sensor networks, connectivity, and satellite navigation, all of which require highly reliable electronic components.
AOPEC offers a comprehensive range of automotive electronic products, including relays, wire harnesses, battery chargers, dual battery management systems, ignition wires, bulbs, and EV charging cables, all manufactured to qualified standards and certified for quality and reliability.
Power Surge Protectors
A multi-application surge protector with a pedestal tester is an all-in-one portable device that combines surge protection and power pedestal testing in a single unit. Simply plug it into the power pedestal to assess power quality, then connect your cordset. It allows you to continuously monitor electrical conditions while your RV remains connected and protected from power surges.
Relays
The most commonly used type of switch in the automotive industry is the electro-mechanically operated relay, which uses an electromagnet to mechanically open or close an electrical circuit. An electromagnetic relay is typically built with a coil of wire wrapped around a soft iron core, forming a solenoid that enables switching when energized.
AOPEC offers a wide range of relays, including mini relays, micro relays, heavy-duty (HD) relays, PCB relays, and solid-state relays. These products support current ratings from 20A to 100A and are available in 6V, 12V, 24V, and 48V versions. They are designed for extended temperature performance up to 125°C, with IP67-sealed and dust-cover options available. AOPEC relays deliver reliable switching performance across multiple automotive applications.
BSRs
Battery Sensitive Relay (BSR), also known as a Voltage Sensitive Relay (VSR), is used in automotive, truck, and marine applications. It monitors input voltage and automatically connects or disconnects the circuit at preset voltage levels, depending on system requirements. It is commonly used in dual-battery systems to prevent over-discharging of the main battery.
AOPEC offers BSR/VSR products in the 12V–24V range with various current ratings. Designed with precise craftsmanship and an optimized structure, these relays function as primary battery protectors, improve charging efficiency, and help extend overall battery life.
Wire Harness
Wire harnesses, also referred to as automotive sockets, are designed to work with compatible relays and provide easy assembly and electrical connection. They are widely used in automobiles as well as construction machinery, offering significant advantages over loose wires and individual cables, including improved organization, safety, and reliability. Despite increasing automation in manufacturing, wire harness production is still largely done by hand due to the variety of processes involved.
AOPEC offers a wide range of wire harnesses in various wire gauges, including 0.5mm, 0.75mm, 1.0mm, 1.5mm, 2.0mm, and 4.0mm, tailored to meet different customer requirements and application needs.
Battery Chargers
A smart charger is a battery charger that can detect the condition of a battery and automatically adjust its charging process accordingly. Car battery chargers are available in different current ratings; units up to two amperes are typically used for maintaining charge in parked vehicle batteries or small batteries used in garden tractors and similar equipment. Higher-rated chargers, ranging from a few amperes up to 10–15 amperes, are commonly used for maintaining automobile batteries or recharging batteries that have been accidentally discharged.
AOPEC smart chargers represent an advancement in battery charging technology, featuring MCU-controlled operation, multi-stage charging processes, ease of use, and quick-disconnection accessories. They are available in 6V and 12V versions, with current options ranging from 0.75A, 1.25A, 2A, 4A, 8A, and 10A up to 20A. All products comply with CE and UL certification standards for European and U.S. markets.
Ignition Wires
An ignition coil, also known as a spark coil, is an induction coil used in a vehicle’s ignition system to convert the battery’s low voltage into the thousands of volts required to produce a spark at the spark plugs, igniting the air-fuel mixture. Modern passenger vehicles may use one ignition coil per engine cylinder (or per pair of cylinders), eliminating the need for spark plug wires and a distributor to route high-voltage pulses.
An ignition coil typically consists of a laminated iron core surrounded by two copper wire windings. Unlike a conventional power transformer, it features an open magnetic circuit, meaning the iron core does not form a closed loop around the windings. The energy stored in the magnetic field of the core is what is released to generate the spark at the plug.
AOPEC offers both open and closed magnetic ignition coils, covering a wide range of vehicle applications, including VW, Honda, Opel, BMW, Audi, Fiat, Toyota, Nissan, Mazda, Ford, Hyundai, and others.
Automotive Lamps
Automotive light bulbs are manufactured in several standardized series. Bulbs used for headlamps, turn signals, and brake lights are often required to comply with international and national regulations governing lighting standards. Other applications, such as auxiliary lighting or interior lighting, may be less strictly regulated, though common bulb types are widely adopted across automotive manufacturers.AOPEC offers a broad range of automotive bulbs, categorized into Group 1, Group 2, and Group 3, including types such as H1, H3, H4, H7, as well as S2 and S3. The product lineup includes halogen, xenon, and LED technologies, all designed for quality performance, durability, and long service life.
EV Car Charging Cables
Electric vehicles (EVs) are growing rapidly, and the demand for related accessories is increasing accordingly. Whether charging at home, at work, or at public stations—using a standard outlet, a high-capacity appliance outlet, or a dedicated charging station—a certified charging cable is essential for ensuring safety and protecting both the vehicle and property.
Charging time depends on battery capacity and charging power, as well as the charging level, which is determined by the voltage handling of the vehicle’s battery and onboard electronics. The U.S.-based SAE International defines Level 1 charging (120V AC household outlets) as the slowest, Level 2 (240V AC) as the mid-speed option, and Level 3 (480V DC or higher fast charging) as the fastest.
AOPEC offers certified Level 1 and Level 2 EV charging cables, available in 10A, 16A, 20A, and 32A options, with multiple cable length choices. All products comply with IEC 60245 and IEC 60227 standards.
Starter Solenoids
A starter solenoid is an electromagnet used to engage the starter motor in an internal combustion engine. It is typically mounted directly on the starter motor it controls. Its primary function is to act as the coil of a contactor (a high-current relay), connecting the battery to the starter motor. In most modern vehicles, the starter solenoid also helps move the starter pinion into engagement with the engine’s ring gear to initiate engine cranking.
