Cost to charge electric car is what every engineer asks before installing a charger at home, a factory, or a power‑plant parking lot.From my 50 years of wiring MCC panels and motor rooms, I’ve learned that charging an EV is mainly about electrical math and knowing your local kWh rate.This guide breaks down the engineering side, real numbers, and the hidden installation mistakes I’ve seen in U.S. facilities. Concept Explained – Understanding Cost to Charge Electric Car Every EV battery is a load just like a motor or UPS bank.The cost to charge electric car depends on three things: Here’s the quick formula we use in the shop or…

Level 1 vs Level 2 EV charging has become the everyday design question in American facilities, garages, and fleet depots. What’s the real difference when you get down to wiring, breakers, and load balance?Let’s talk shop, not brochure talk and compare how these two charging methods behave where copper meets concrete. Fig-1: Level 1 vs Level 2 EV charging comparison diagram showing 120 V and 240 V circuits Concept of Level 1 vs Level 2 EV charging Every EV charger, officially called EVSE (Electric Vehicle Supply Equipment) is just a managed power outlet with ground monitoring and a communication handshake.The Level 1 type feeds from a 120‑volt single‑phase receptacle, current‑limited to about…

VFD failure and prevention: Real Engineering Lessons from the Field VFD Failure and Prevention is key to longer drive life. VFD Failure and Prevention reduces downtime. VFD failure and prevention – why do variable frequency drives suddenly blow capacitors, trip on over‑current, or roast IGBTs at 2 a.m.? Let’s walk through what really happens inside those cabinets engineers trust to keep motors spinning and plants running.

Create project in RSLogix 5000 is the first step for anybody learning Rockwell Automation controllers. This practical guide walks you through every step through each step, from starting a new project file to naming your controller and configuring the chassis. And, you can start programming with certainty. Whether you are using a CompactLogix 5370 or a ControlLogix system, understanding RSLogix 5000 architecture makes your PLC run faster and more reliably. The first step in creating a project in RSLogix 5000 is programming the PLC. Many people wonder whether this software is compatible with every PLC. RSLogix 5000 works with families…

Introduction A Variable Frequency Drive is being used in industry to control the speed of an electric motor by adjusting the frequency and voltage. It helps motors operate at the right speed to meet the process requirements, which reduces energy waste and extends the motor’s life. Motor speed controller are widely used in many industries, including power plants, chemical processing plants, food production plants, HVAC systems, water treatment, and automotive production. Why do these industries depend on VFDs to control motor speed, because it improves efficiency, and reduces energy consumption. In short, VFD actually adjust the motor speed to save…
