👇 A look at several of our onboard charging solutions for EV applications.

Our integrated OBC, DC/DC, and PDU systems are developed for a wide range of vehicle platforms, covering passenger vehicles as well as commercial vehicle applications such as logistics vans, buses, sanitation trucks, minibuses, pickups, and street sweepers.

The platform currently covers charging power from 3.3 kW to 20 kW, including solutions for 800 V high-voltage architectures.

From a vehicle integration perspective, combining OBC, DC/DC, and PDU into a more compact system helps simplify wiring layout, reduce packaging complexity, and improve overall power density.

Different vehicle platforms naturally come with different operating requirements, so the focus is not only on charging capability itself, but also on system efficiency, thermal performance, reliability, and integration flexibility.

As EV platforms continue evolving toward higher voltage and more compact architectures, integrated power electronics are becoming increasingly important at the vehicle system level.

For heavy-duty and vocational truck electrification, the challenge is often not peak power alone, but how to deliver torque smoothly and efficiently across very different operating conditions.

Our e-powertrain solution combines high-torque traction motors with 2-speed or 4-speed AMT transmissions, helping vehicles maintain both low-speed pulling capability and efficient cruising performance under load.

Compared with single-speed architectures, the multi-speed setup allows better torque distribution across different speed ranges, improving:

● loaded launch performance
● gradeability
● low-pseed maneuverability
● highway efficiency

Shift control is also optimized to reduce driveline interruption during gear changes, helping improve overall drivability under real working conditions.

For vocational truck applications, PTO functionality can also be integrated directly into the e-powertrain system to support auxiliary equipment while simplifying overall vehicle layout.

The system has undergone durability validation and road testing under representative operating conditions to verify long-term stability and reliability.

🔋 Another lesson learned from a commercial vehicle battery project.

During testing on a customer vehicle, one battery pack was partially damaged after an external impact and could no longer remain in service. To get the vehicle back on the road quickly, the idea was raised to replace the damaged pack with another pack of the same model from inventory or another vehicle.

Our battery engineering team explained that for commercial vehicle battery systems, pack replacement is not simply a matter of matching model numbers or specifications. Parameters such as cell capacity consistency, pack voltage, SOC, aging condition, and historical usage all need to be evaluated together before replacement decisions are made.

Due to project timing pressure, replacement was eventually carried out directly using another battery pack without a full technical assessment.

After a period of operation, the vehicle developed a significant battery imbalance at the system level, which later became difficult to recover through normal calibration.

📌 Cases like this highlight an important aspect of battery system integration: consistency management is just as critical as the hardware itself. Even when packs appear identical on paper, differences in aging, operating history, and state conditions can gradually affect overall system stability.

It also reinforces the importance of standardized service procedures and technical training during vehicle operation and maintenance, especially for commercial vehicle electrification projects operating in real-world fleet conditions.

One recent project reminded us again that for commercial vehicle electrification, the real challenge is often not the hardware itself, but whether the duty cycle and vehicle application are correctly defined from the beginning.

In this case, our heavy-duty truck e-axle was integrated into a bus platform. The vehicle operated mainly on rough and hilly roads, with frequent hard acceleration and braking. These conditions generated repeated high-impact loads, eventually leading to motor fault alarms and vehicle power limitation.

Our engineering team became deeply involved in the investigation process. We followed the actual vehicle routes on-site, collected road spectrum data, and analyzed the real operating conditions instead of relying only on the original vehicle specifications.

Based on the findings, the control strategy was optimized to reduce torque spikes during sudden acceleration and deceleration, smoothing impact loads under harsh operating conditions. The motor control software was then updated and validated on the fault vehicles, after which the solution was rolled out to resolve the issue across the fleet.

What made this case particularly interesting was that the direct issue was not component capability. The e-axle itself had originally been developed for heavy-duty truck applications. The real problem was that the actual vehicle application and operating conditions differed significantly from the original integration assumptions.

📌The project also reinforced an important point for EV integration projects: accurate vehicle information, duty cycle definition, and operating environment data are critical for system matching and control strategy development.

In commercial vehicle electrification, real-world operating conditions always matter more than paper specifications.

Three-piece e-axle housings are often discussed for flexibility and manufacturing convenience. But under heavy-duty, high-load conditions, the limitations become quite clear. 👇

When axle load goes beyond ~13 tons, the fl**ge-connected housing starts to show fundamental weaknesses:

1️⃣ Reduced structural stiffness

Bolt preload relaxes under cyclic loading, leading to a measurable loss in overall housing rigidity

2️⃣ Stress concentration at fl**ge interfaces

Local stress peaks can reach ~420 MPa, significantly higher than integrated housings (~280-290 MPa)

3️⃣ Fatigue and sealing risks increase rapidly

Micro-movements at the fl**ge accelerate wear, leading to earlier crack initiation and higher leakage risk over time

At the same time, deformation under load begins to affect transmission behavior:

● Gear alignment deviation under load
● Transmission error increases multiple times compared to no-load conditions
● Noticeable NVH deterioration in high-speed operation

From a system perspective, these effects are coupled: structure, transmission, and sealing all interact.

In contrast, integrated axle housings show a much more stable behavior under the same load level:

● Lower stress concentration
● Longer fatigue life
● More consistent sealing performance

That's why for heavy-duty applications, especially in demanding and unpredictable operating conditions, structure matters more than theoretical flexibility.

In the end, heavy-duty transport is less about pushing limits and more about how the system holds up after millions of load cycles.

At Brogen, our heavy-duty e-axle platform adopts an integrated housing design, with a load capacity of 16T, developed specifically for these scenarios.

At the recently concluded Beijing International Automotive Exhibition 2026, one shift stood out more than any vehicle launch.

For the first time, battery manufacturers were exhibiting alongside OEMs in the same halls. That's more than just a layout change; it reflects how the center of gravity in the industry is evolving.

One clear direction from this year's show: ultra-fast charging is becoming the next battleground.

What used to be 4C is now moving toward 5C, 10C, and beyond, and this will directly influence platform decisions for commercial vehicles over the next few years.

A few highlights 👇

📌 CATL

Their latest generation ultra-fast charging battery drew a lot of attention.

● Up to ~10C charging (peak even higher)
● 10% to 98% SOC in just over 6 minutes
● Around 9 minutes charging even at -30°C

For commercial vehicles operating in cold regions, low-temperature performance is particularly relevant.

They are also pushing a combined fast-charging + battery swapping network, aiming to support both short-haul high-frequency operations and long-haul transport.

📌 BYD

BYD is taking a different approach with its fast-charging strategy.

● 10% to 70% SOC in about 5 minutes
● Near-normal charging performance even at -30°C
● Focus on building a large-scale ultra-fast charging network

Compared to CATL's hybrid model (swap + charge), BYD is going all-in on fast charging infrastructure.

📌 Challenge

Faster charging means higher stress on the battery, especially in terms of lithium plating and thermal risks.

How these systems perform over time, especially degradation under real fleet operation, is something the industry still needs to validate at scale.

It's a fast-moving space, and the next 2-3 years will likely define which technical routes actually hold up in real-world use.

Heavy-duty truck electrification is not a single step; it's a progression.

If you look at platform development across different stages, the changes go far beyond just replacing the power source. They start to reshape the entire vehicle, from chassis layout to cab design.

A simplified view:

Stage 1️⃣ - Fuel-powered truck

● The platform, cab, and layout are all built around the engine and transmission.
● Battery is not a consideration, and aerodynamics and cabin design follow traditional ICE constraints.

Stage 2️⃣ - Diesel-to-electric conversion

The powertrain shifts to electric, but the platform largely stays the same.

● Battery layout is adapted to the existing space
● Cab structure and exterior remain close to original designs
● Limited changes in aerodynamics and interior packaging

This stage is practical, but still constrained by legacy architecture.

Stage 3️⃣ - Purpose-built electric truck

This is where things start to look fundamentally different.

● Platform is designed around battery layout and e-axle integration
● Cab structure is rethought for space and driver experience
● Exterior design evolves with aerodynamics in mind
● System integration becomes more compact and efficient

At this stage, electrification is no longer just a powertrain change; it becomes a full shift in vehicle architecture.

In reality, all three stages are still relevant today, depending on timing, cost targets, and application needs.

Different paths, same goal: making electrification work in the real world.

When does a centralized electric drive axle actually make sense?

🚛 1️⃣ Resource Transportation (aggregates, coal, ore)

This architecture is a strong fit when:

● Routes are relatively predictable (yards + regional roads / highways)
● Harsh conditions exist, but are not continuous (no deep ruts or extreme terrain)
● The goal is a balanced trade-off between cost, efficiency, and durability

Key signals:

● Ground clearance requirement: >260 mm
● PTO needed for tipping or hydraulics
● Multi-speed gearbox required for start, gradeability, and cruising

🚚 2️⃣ Express & Line-haul Logistics

A centralized solution works well when:

● Vehicles operate mostly on highways with stable road conditions
● Annual mileage is high → efficiency becomes a key cost driver
● Duty cycles are consistent, without extreme gradients

Key signals:

● Energy consumption per km is a core KPI
● 2-speed transmission is typically sufficient
● Lightweight drivetrain design supports efficiency-focused operation

For light commercial EV platforms, drivetrain architecture directly impacts packaging, cost, and vehicle performance.

Two common approaches:

1️⃣ Central Direct Drive (traditional layout)

Motor (or+ Reducer) → Universal Driveshaft → Traditional Drive Axle Assembly (Main Reducer + Differential + Half Shafts) → Wheels

This layout follows the ICE vehicle structure by replacing the engine with a motor.

✔ Shorter development cycle
✖ Occupies significant longitudinal (X-direction) space
✖ Limits battery packaging flexibility
✖ Potential axle load imbalance (front-heavy layouts)
✖ Higher system weight and complexity

2️⃣ Electric Axle (e-axle)

Motor → Drive Axle Assembly (Cylindrical Gear Main Reducer + Differential + Half Shafts) → Wheels

By integrating key components into a single unit:

✔ Frees up underfloor space for battery integration
✔ Reduces component count and overall weight
✔ More flexible vehicle layout and axle load distribution
✔ Higher system efficiency with a more compact structure

In one of our LCV projects, this integration reduced 11 component types and ~33 kg from the system.

📌Takeaway

For most light commercial vehicles, especially where payload, cost control, and scalability matter, the e-axle architecture offers a more balanced and practical solution.

For vans and light trucks, waterlogged roads, mud, and frequent stop-and-go in suburban or rural areas are quite common. Over time, these conditions tend to show up first in components like bearings.

This is where durability matters more than peak numbers.

Our traction motor platform for LCVs is designed with this in mind:

● IP68 protection for operation in wet and muddy environments
● Sealing and structural design to reduce contamination and moisture impact

In lab testing, the bearing system has been validated for 300,000 km without abnormal noise.

For this type of application, durability is less about extreme specs and more about how the system behaves after thousands of hours in imperfect conditions.
