In the automotive electronics development industry, the software development V-model derived from ISO26262 is increasingly accepted by developers. A crucial part of the V-model is HIL (Hardware-in-the-Loop) testing. Depending on the specific product form, the specifics of the V-model may vary, but it generally follows the overall process of requirements, design, and verification. For the … Read more
PMIC Report Summary Chips are generally divided into two major categories: analog and digital chips. Among them, analog chips include analog signal chains and mixed-signal chips, power devices, RF radio frequency devices, and sensors. Power devices are further divided into Power Management Integrated Circuits (PMICs) and power devices. The technologies and application areas related to … Read more
Currently, the communication for vehicle control in new energy vehicles is mainly based on the CAN bus. Almost all Electronic Control Units (ECUs) communicate via the CAN bus, including BMS, braking systems, motor control, etc. Since the vehicle CAN bus messages contain real-time data from key system components, parsing the vehicle CAN bus message data … Read more
1 CAN Bus System The full English name of the CAN bus is Controller Area Network, which is one of the most widely used buses in automobiles. Pure electric vehicles generally have seven CAN bus systems, which are named differently by various automobile manufacturers, commonly referred to as: New Energy Bus (EVBUS), Fast Charging Bus … Read more
The definition of SOC (state of charge) varies widely, but a more unified international definition is based on capacity, representing the remaining capacity of the battery with SOC, which numerically equals the ratio of the remaining capacity Q to the maximum available capacity Qmax. SOC estimation is one of the key technologies in battery management … Read more
Click the above “Mechanical and Electronic Engineering Technology” to follow us Hey friends, today let’s talk about a topic that is both high-tech and close to our lives—PCBs (Printed Circuit Boards) in new energy vehicles. Sounds a bit fancy and mysterious, right? Don’t worry, we will slowly unveil its veil and see how this “unsung … Read more
Today’s electronic devices, ranging from TWS headphones and wearable devices to electric vehicles, rely heavily on lithium-ion or polymer batteries for power. Depending on the power requirements of the electronic devices, a battery pack may consist of multiple battery cells (cells) arranged together. The charging and discharging of the battery pack, as well as the … Read more
Next year, public utility operators will face more new challenges in industrial cybersecurity. However, the good news is that new developments will also help minimize these threats. The bad news is: more complex ransomware will emerge; the Industrial Internet of Things (IIoT) will bring more threats; and the severe shortage of cybersecurity talent will continue … Read more
The voltage of electric vehicle batteries is increasing from 400V to 800V, and the voltage of large-scale energy storage system batteries is rising from 600V-900V to 1500V. Engineers face a dilemma when proposing hardware-in-the-loop (HIL) requirements for high voltage battery BMS: the number of battery cell channels versus the simulation effectiveness. When the number of … Read more
