What is Feedback and Feedforward control in Automotive?

Feedback control – The system output to adjust the system input by correcting errors and disturbances. For example: Cruise control system to maintain a constant speed by measuring the actual speed and comparing it with the desired speed. Feedforward control – The system input to predict the system output and feedback control systems is used to correct the prediction errors and ensure…

ARM Processor

Hey viewer! watch out ARM Processor - Cortex Family

An ARM processor is one of a family of central processing units (CPUs) based on the reduced instruction set computer (RISC) architecture for computer processors. ARM stands for Advanced RISC Machine. ARM architectures represent a different approach to how the hardware for a system is designed when compared to more familiar server architectures like x86. Acorn Computers first developed the ARM…

Electric Vehicle History

Hi, Checkout my post!

In the late 1890s electric vehicles (EVs) outsold gasoline cars ten to one. EVs dominated the roads and dealer showrooms. Some automobile companies, like Oldsmobile and Studebaker actually started out as successful EV companies, only later did they transition to gasoline-powered vehicles. In fact, the first car dealerships were exclusively for EVs.Early production of EVs, like all cars, was…

Li Ion Batteries

Battery Impedance Measurement:

Impedance depends upon chemical properties and mechanical design

Measured using frequency range 1Hz to 10MHz by injecting small current (Z=Vout/Vin)

At 1kHz Li Ion Cell of charging and discharged will show impedance of 68.6 milli ohms

If impedance is more then cell life cycle will be less.

Charger Control:

BMS help to control the charger to protect battery packs and…
