From one of our overseas bus #electrification projects, we learned an important #engineering lesson: even an electric axle designed for HCVs can face unexpected challenges if the real duty cycle is not clearly defined upfront.

From a software perspective, one of our electric axles was originally designed and calibrated for smooth road conditions with low shifting demand, such as highway operation. This calibration works well in scenarios with stable load transitions and limited gear shifting.

In this overseas application, the e-axle was used on a bus operating under very poor road conditions. Uneven roads, frequent stop-and-go operation, and intensive shifting placed much higher dynamic demands on the shift control system and motor than initially assumed.

Before our engineers arrived on site, this situation was puzzlin

From an engineering standpoint, the e-axle was developed for heavy-duty truck applications, where the overall load levels are typically higher than those of city buses. Based on this assumption alone, such behavior was not expected.

Clarity came only after our engineering team was dispatched to the customer site and began collecting real road spectrum data. The data showed that, although the vehicle was lighter, the actual duty cycle was far more aggressive in terms of shifting frequency and dynamic road variation.

Based on real operating conditions, we conducted multiple iterations of control software tuning and logic optimization.

As a result, the system operating issues were effectively resolved.

From a system integration perspective, we also identified that the vehicle was not equipped with a pressure-limiting valve. In our typical domestic applications, system pressure is controlled below 8 bar, while in this overseas case, the operating pressure reached 11-13 bar, further increasing system stress.

📌 Key takeaway:
Electric axles are system-level solutions, not plug-and-play components. Clear communication of real duty cycle information — especially for overseas markets with challenging road conditions — is essential for proper software calibration and reliable system performance.

In recent years, #IGBT has become a hot topic. Industries such as electronics, semiconductors, automotive, energy, power, and control systems all seem to be connected to it. As a relatively modern technology, the IGBT, with its efficient power management capabilities, is indeed driving upgrades and transformation across these fields.

🤔 What is an IGBT?

An IGBT can be understood as an electronic switch that uses a small voltage to control a large current. It serves as the core of energy conversion and control.

A simple analogy is a water faucet:
● Gate (G): The faucet handle. With just a small effort (a small control signal), you can open or close it.
● Collector (C): The water inlet, connected to the source.
● Emitter (E): The outlet, where the water flows out.

The IGBT itself is like the faucet mechanism. Its essence lies in this: with a tiny action (a signal to the gate), it can precisely control the flow of a massive amount of energy (the large current between the collector and emitter).

📌 Internal Structure and Working Principle of IGBT
The structure of an IGBT can be seen as a combination of a MOSFET and a bipolar transistor.

● Turn-on: When a positive voltage is applied between the gate (G) and emitter (E), an electronic channel forms (similar to a MOSFET turning on). At this point, the IGBT behaves like a conductor, with very low resistance and minimal loss.

● Turn-off (OFF): When the voltage between the gate (G) and emitter (E) is removed (drops to 0 V), the electronic channel disappears. The IGBT then acts like a barrier, blocking current flow.

IGBT is the cornerstone of EV power electronics, delivering efficient energy conversion and reliable performance—driving higher efficiency, safety, and the future of electric mobility.

🔍 What is HVIL? Why It’s Critical for EV Safety?🚗
As electric vehicles (EVs) evolve with higher voltage platforms - from 400V to 800V and even 1000V to support ultra-fast charging, the safety challenges also escalate. That's where HVIL comes in.

HVIL is a smart safety mechanism that monitors the integrity of the high-voltage (HV) circuit using a low-voltage loop. Its purpose? To prevent arc faults, high-voltage exposure, and unexpected power loss - issues that could seriously endanger passengers and service personnel.

🔐 How It Works:
● Special HVIL connectors use staggered pin designs to ensure high-voltage lines only engage after the interlock loop is confirmed.
● If any connector is loose, damaged, or removed, HVIL instantly cuts off the high-voltage supply.
● It supports real-time monitoring through voltage, current, and PWM-based detection circuits - essential for fault diagnostics and precise location tracking.

🛠️ Applications in EV Systems:
HVIL is integrated into batteries (BMS), inverters (MCU), onboard chargers (OBC), HVAC, and more. Depending on the component’s criticality, HVIL faults are classified into different levels:
● Level 1: Critical components (BMS, OBC) → Immediate HV shutdown
● Level 2: Drivetrain (motor, inverter) → Power reduction & safe stop
● Level 3: Auxiliary (PTC heater, A/C) → Function restriction only

HVIL doesn’t just ensure safety—it enables intelligent diagnostics, predictive maintenance, and higher voltage adoption across modern EV architectures.
