Part I of this series examined how large-scale platform modularity, particularly in EVs, can introduce design tradeoffs and system-level ripple effects once real engineering constraints appear. Promised flexibility often gives way to added … [Read more...]
Part I: Why it’s important to be wary of “platform” and “modular” architectures
Editor's note: This article is particularly relevant to electric vehicles because EVs are far more architecture-sensitive than ICE vehicles. Changes in voltage level, battery chemistry, drive layout, or regenerative braking ripple through the … [Read more...]
Will AI-managed EV charging tell us what to do and when?
Every story these days seems to connect its message or theme to artificial intelligence (AI). Some of these connections have validity, while others are a “reach” for others who want to appear on-trend and relevant. The latter are of interest … [Read more...]
How zonal automotive power distribution can improve efficiency
Today’s vehicles are loaded with electronics, sensors, control units, safety features, infotainment and advanced driver-assistance systems (ADAS), as well as dozens of small and big traction motors. Providing, managing, and delivering the required … [Read more...]
Vehicle-to-grid is technically feasible, but what’s the reality?
A concept may be elegant and even possible to implement, but the actual benefits are dubious — especially with the stress it gives to users. You’re probably somewhat familiar with the idea of vehicle-to-grid (V2G) automobile energy transfer. It’s … [Read more...]
FAQ on AEC-Q100 Automotive IC Reliability Standard, Part 2
To ensure that the myriad electronic systems in today’s vehicles do not fail prematurely, the AEC-Q100 standard for active components defines stringent tests across all aspects of performance. This part continues the exploration of AEC-Q100 and … [Read more...]
FAQ on AEC-Q100 Automotive IC Reliability Standard, Part 1
To ensure that the myriad electronic systems in today’s cars do not fail prematurely, the AEC-Q100 standard for active components defines stringent tests across all aspects of performance. In just a few decades, the automobile has gone from a … [Read more...]
What is a traction motor and when should it be used?
Motors are essential components in several applications, powering equipment in many industries. In simple terms, a motor is a device that converts electrical energy into mechanical energy, generating motion or providing rotational force. Different … [Read more...]
How many electric motors are in a vehicle?
The first gasoline vehicles had no electric motors. In contrast, today’s cars have tens of “invisible” motors with a range of power levels, sizes, and types. It’s not news that today’s vehicles, regardless of their motive power source, are packed … [Read more...]
