Design a 48V 8A Lithium battery (CC-CV) charger

Hi, My name is John Lester Soronio. I am a senior charger and power supply design engineer at Artesyn Embedded Technlologies (formerly Emerson Network Power). I am a lead engineer and leading several products in the market. The most most recent products released in the market that I am part of are: [login to view URL] [login to view URL] These power supply has CC and CV features. Other power supply released to the market are 750W 94% Eff, 500W 92%, 450w multi output 92% eff, off line adapters 100W and 5W chargers. I am new in freelancer but not in upwork/odesk and elance. Considering my more than 10 years experienced in design I can give you a good solution Summary of Capabilities: 1. AC-DC and DC-DC power supply design, multiple outputs or single, trimmable or fixed 2. Offline AC-DC adapter design 3. Charger design with constant current and constant voltage, AC-DC 4. Charger design with constant current and constant voltage , DC-DC for Li-Ion, Li-Poly, LiFeP04, Lead acid and so on 5. LED lighting related applications 6. Solar panel energy harvesting and charging systems 7. Switching converters such as buck, boost, buck-boost, flyback, forward, LLC, half bridge etc 8. Schematic and PCB using eagle 9. Simulations; LTSpice, Matlab, Simulink, Simetrix and Simplis, Mathcad 10. Control system design

Hi, I am a post graduate power electronics engineer and having excellent design and development knowledge in power supplies,SMPS,DC-DC,AC-DC,Battery chargers design using different topologies like flyback,push pull,boost,buck,Forward and buck boost. I have design experience from few watts to KW range using universal supply range. I have experience in Lead acid battery chargers,lithium ion and LiFePo4 battery chargers.I understand your requirement and ready to work for you. Please contact me for further discussion.

Over 12 years of experience in electronics hardware and software design. Proficient in software and hardware design of embedded systems. Successful in planning and management of entire development and production cycle. Programming languages: C, C++, Ada, Pascal, MATLAB, GPSS, VHDL Processor architectures: 8051, AVR, ARM-M3, ARM-R4, ARM-7, x86, PicoBlaze, PSoC, PIC FPGA and CPLD architectures: Cyclone, MAX, Spartan, CoolRunner Set of rules to be stated before work: - All milestones should be backed up by you. So you release the money for milestones when you receive work done for each milestone and happy with it. - All decisions that I will make during the development that were not stated in project description I may do on my own understanding. I may ask you, if something was not described but not necessary I will do so. - Any changes that are to be entered by you for the project description, results, milestones, etc. after me accepting the project are subject to discussion and may lead to extra payment. - Next milestone work will begin only after finishing the previous one and releasing payment for it. - Prototype cost, delivery costs, components, PCB manufacture and other costs not connected with solely my services are extra payed when they are determined.

Professional electronics engineer can take care ............................................................................

Hi, I can do this. I have an experience of designing this. If you are interested to work with me, then kindly reply back. Thanks. Chirag

A proposal has not yet been provided

Are you looking for the concept or poc made. If you are looking for only concept I can do it in 20 K. If you are looking for the complete engineering design, 35 K is my bid. If you are looking for poc with testing and validation, my bid is 75 k

Hello, I have over three years in academic research. I have a degree in Electrical and Telecommunication Engineering hence i am fit for this project proposal. I am currently working on a project "DESIGN OF SINGLE PHASE H-BRIDGE MULTILEVEL INVERTER USING MICROCONTROLLER ATMEL 89C51" for an MSc degree for another client. Hoe that make me fit for this one Please find it fit to assign me this order and i promise to provide a high quality work and will deliver in time. I can provide samples of my previous work if you would like me to. Please contact me ASAP Thanks for considering my application

Hi, I am Electrical Engineer with lot of experience in matlab, simulink, Electronics, c, c++, Microcontroller, FPGA. I have the complete solution for you problem, i need to calculate the values according to your specifications. I have used the buckboost converter for charging the battery. We can use MPPT as well for tracking the point for quick charging of battery. I have the complete code for MPPT as well. I have used the perturb and observb method for mppt. Looking forward to work with you, Regards, Farhan

May i see the full data-sheet on a battery? For СС-СV lithium charging need a known safety characteristics of battery or have a thermal sensor inside the battery... 8A = 8AH battery or 8A charging current

I have completed my masters in Power Electronics from IIT Madras. I have good experience in design of Dc Dc converters, inverters and chargers.

I have experience in the same. I can help you. Pay after you really like it. I will do it with its detailed description.

Dear Team, Greetings!!! This is Aditya Thakekar Electronics Engineer,passionate to work on Electronics Projects, have successfully worked with on IoT based Home automation and Wearable Electronics, wish to know more about your project and apply for the same. Kindly inform. Eagerly awaiting your reply. Best regards, Aditya

I feel I would be the best candidate for this project. I have designed a variety of charging circuits for Lithium Ion batteries, one particular was a trickle charger which could operate with 115 or 230 volts. I am also very experienced at designing efficient schematics and PCBs, and would love to work with you.
