Introduction to Hybrid and Electric Vehicle Battery Systems

by Vivek Choudhary Nice life

What is a hybrid? A hybrid vehicle combines any two power (energy) sources. Possible combinations include diesel/electric, gasoline/flywheel, and fuel cell (FC)/battery. Typically, one energy source is storage, and the other is the conversion of fuel to energy. The combination of two power sources may support two separate propulsion systems. Thus to be a True hybrid, the vehicle must have at least two propulsion modes.

Driven by the need for lower emissions, better fuel economy, and higher efficiency, hybrid vehicles appear in many different configurations on today's roadways. While the powertrain components such as the drive motor, motor controller and cooling system are somewhat familiar to the automotive industry, the battery systems are relatively unfamiliar.

This EV Battery Masterclass will introduce participants to the concepts of hybrid vehicles, their missions, and batteries' role in fulfilling those requirements. Battery topics including limitations, trends in hybrid development, the customer wants and needs battery system development timelines, and electrochemistry and safety will be examined. Current offerings, cost factors, pack design considerations, and testing will also be reviewed.

Students will have an opportunity to perform a battery pack analysis exercise using a real-world application and are requested to bring a calculator to class.

Learning Objectives

By attending this meeting, you will be competent to EV Battery Online Courses:

·         Capture customer desires and anticipations of the battery system.

·         Recognize characteristics that force power and energy conditions.

·         Demarcate test timetable structure.

·         Compare and discern the most contemporary, suitable battery technologies.

·         Calculate estimations of electric range and quantify the assumptions.

·         Critically consider media insistence of new battery finds.

Who Should Attend

EV Battery certification courses are primarily intended for vehicle systems engineers, battery system integration engineers, testing engineers, electrical engineers, and thermal management engineers recently assigned to their roles or returning to hybrid or electric vehicle programs. It will also benefit those involved in designing, developing, testing, and planning hybrid vehicle programs. Product planners and program managers will find the overview aspects helpful.

Prerequisites

The material presented will be practical, with basic mathematics used to describe quantitative measures. An undergraduate degree in electrical or electromechanical engineering will assist in gaining maximum benefit from the material presented. Experience or training in battery electrochemistry is helpful but not essential as Online EV courses.

These two power origins may be paired in succession, suggesting that the gas engine charges the batteries of an electric motor that powers the car, or in parallel, with both mechanisms driving the car verbatim. Uniform with the meaning of hybrid above, the hybrid electric vehicle integrates a gasoline engine with an electric motor. An alternate arrangement is a diesel engine and an electric motor.

An HEV is formed by merging components from a pure electric vehicle and a pure gasoline vehicle. The Electric Vehicle (EV) has an M/G, which allows regenerative braking for an EV; the M/G installed in the HEV enables regenerative braking. For the HEV, the M/G is tucked directly behind the engine. The M/G is connected directly to the engine in hybrids. The transmission appears next in line. This arrangement has two torque producers; the M/G in motor mode, M-mode, and the gasoline engine. The battery and M/G are connected electrically.
