Passenger Vehicles & NEV Battery Solution

Reliable starting and stable low-voltage power for conventional, Start-Stop, hybrid and electric vehicles.

Powering Every Generation of Passenger Vehicle

As vehicle architectures evolve, the demands placed on low-voltage batteries continue to grow. In conventional vehicles, the battery must deliver dependable cranking power and support lighting, ignition, and onboard electronics. Start-Stop platforms require stronger cycling performance, rapid charge acceptance and reliable power while the engine is off. In hybrid and electric vehicles, low-voltage batteries support control units, safety functions, communication systems and vehicle activation—even when propulsion comes from a high-voltage traction battery. As infotainment, comfort features and other onboard electronics increase electrical demand, selected vehicle platforms also use dedicated auxiliary batteries to maintain a stable power supply for secondary systems.

LEOCH addresses these diverse duties with AGM, EFB, maintenance-free flooded, high-temperature, auxiliary and dedicated NEV battery solutions for OEM and aftermarket applications worldwide.

The Essential Low-Voltage Power Behind Every Journey

Conventional ICE Vehicles

The battery cranks the engine and supplies the starting, lighting, ignition, and electronic systems before the alternator takes over.
Start-Stop Vehicles

The battery repeatedly restarts the engine, supports onboard electrical loads while the engine is off and accepts energy during frequent recharge events.
Hybrid & Plug-In Hybrid Vehicles

The low-voltage battery powers control units, safety systems, lighting and vehicle electronics while supporting system initialization and operation.
Battery-Electric Vehicles

Although the traction battery provides propulsion, the low-voltage battery wakes the vehicle, powers its control network and enables the sequence that brings the high-voltage system online.
Auxiliary Battery Applications

In vehicle platforms equipped with a secondary battery, the auxiliary battery provides stable power for onboard electronics, infotainment, comfort features and other designated electrical systems, helping manage growing low-voltage demand.

New Energy Vehicles

High-Voltage Mobility Still Depends on Low-Voltage Power

Explore LEOCH NEV Battery Solutions

The high-voltage battery drives an electric vehicle, but low-voltage power brings it to life. When the traction system is isolated, the auxiliary battery keeps access, monitoring, communication and control functions active—then enables the high-voltage system to start. Without dependable low-voltage power, an EV may remain unresponsive even with energy in its traction battery. LEOCH NEV batteries deliver reliable, application-matched support for electric and hybrid vehicles.

FAQs

Q. What information is needed for a product recommendation or quotation?

Provide the target market, vehicle application, required battery technology, fitment standard, capacity, CCA, dimensions, terminal layout, expected annual volume and any certification or private-label requirements.
Q. What affects automotive battery service life?

Temperature, charging voltage, driving patterns, electrical loads, discharge history, battery location and vehicle energy-management settings all influence service life. Extended undercharging and sustained high temperatures are particularly damaging.
Q. What is the difference between a starter battery and an auxiliary battery?

A starter battery is primarily designed to deliver high current for engine cranking. An auxiliary battery supports secondary electrical loads or backup functions. Their performance requirements and physical formats may differ, so they should not be treated as interchangeable.
Q. Can an EFB battery be upgraded to AGM?

An EFB battery may be upgraded to AGM when the physical fitment, charging system and vehicle manufacturer's requirements allow it. An AGM-equipped vehicle should not normally be downgraded to EFB or conventional flooded technology.
Q. Can a conventional MF battery be installed in a Start-Stop vehicle?

No. A conventional flooded starter battery is not designed for the repeated cycling and charge-acceptance demands of a Start-Stop system. Installing the wrong technology can shorten battery life and affect system performance.
Q. What is the difference between AGM and EFB batteries?

AGM batteries generally support more demanding Start-Stop systems, higher electrical loads, stronger cycling and partial-state-of-charge operation. EFB batteries provide enhanced performance over conventional flooded batteries for standard Start-Stop applications.
Q. When should a High-Temp MF battery be used?

Our High-Temp series is specifically recommended for vehicles operating in consistently hot climates (such as the Middle East, Africa, or tropical regions), where standard batteries are prone to rapid grid corrosion and water loss.
Q. What type of battery does my vehicle require?

Battery selection should follow the vehicle manufacturer’s requirements. Confirm the battery technology, dimensions, terminal layout, hold-down, capacity, CCA and whether the vehicle has a Start-Stop or energy-management system.
Q. What is the difference between a starter battery and an auxiliary battery?

A starter battery is primarily designed to deliver high current for engine cranking. An auxiliary battery supplies designated secondary electrical systems, such as onboard electronics, infotainment and comfort features. Because their duties, charging conditions and physical formats may differ, the two batteries should not be treated as interchangeable.
Q. Why do electric vehicles (NEVs) still need a 12V battery?

While the high-voltage lithium battery powers the drivetrain, the 12V NEV auxiliary battery is critical for safely powering the vehicle's computer systems, lighting, door locks, and safety relays, especially before the high-voltage system is engaged.
Q. What is the difference between AGM and EFB for Start-Stop vehicles?

AGM (Absorbent Glass Mat) is the premium technology designed for vehicles with advanced Start-Stop systems, regenerative braking, and heavy electrical loads. EFB (Enhanced Flooded Battery) is a highly durable, cost-effective alternative typically used in standard Start-Stop vehicles without regenerative braking.
