Battery charge Manager

Hello! I am electric engineer, and i have experience in development of electrotechnical products, in particular power and control electronics for autonomous power supply systems, electric vehicles, etc. Algorithmization, setting and programming the control electronics of any complexity based on ARM microcontrollers. I can design electrical circuit board and electrical PCB based on your specification, UPS systems related to solar, wind or other alternative energy, as well as charge controllers and other power electronics for various needs. I can create programs for ARM microcontrollers (stm32) for projects such as made by me and other people. Doing projects on time, correctly and always try to understand what customer wants to prompt and make the project better.

Hi, I am a Senior Electrical Engineer and recently I have designed lithium ion battery charger. I can definitely help you with this project and if you can share more details, I can give you more detailed quote and how it would take. I can surely test your circuitry for you as well. Thanks

hi, i am an electrical engineer and i can design your project as i already have designed the battery chargers controlled by PIC microcontrollers. the charger will show the battery status(battery voltages), charging indication and automatically stop charging when a required amount voltage present. Please contact me for further details. Thanks, Rizwan

Hi I read project description and I am ready for this project. I can do this project with or without micro-controller. I have done such project in past. PM me.

La propuesta todavía no ha sido proveída----------------------------------------------------------------------------------------------

i have done some project about battery charger so I think i can do this project. Don't hesitate contact me if you have any problem that has explained.

A proposal has not yet been provided

I hold Bachelor's Degree in Electrical Engineering with specialization in Power Electronics. You can see on my profile that I have successfully finished a similar project recently. I would conceive this circuit around isolated BUCK switching converter. Isolation from mains voltage is of paramount importance because it is necessary to protect battery and micro-controller from high voltage. The question is only what degree of control do you want micro-controller to have over this charging circuit? Is it only to turn it on and off, or does it need to have control over voltage and current regulation? For this price, I am offering design of a circuit schematic and PCB designed in Altium Designer.

I have extensively worked on power supplies and battery management systems. I can assure you best quality and on-time delivery.

I have a 100% tested schematic ready for charging 3.7/4.2V Li-Ion battery. It can be modified with minor changes to interface & controlled using a microcontroller of your choice. The schematic also features an LED status indicator for charging status indication. The schematic has been designed to be powered using 5V DC supply. Your load circuit would be powered by 4.2V when external power is present and simultaneously charges the Li-Ion battery. When the main power is absent, it automatically switches to battery power (4.2V). An additional option to control this circuit using external microcontroller can be provided (although not required) can be provided. Note: I expertise in the field of Embedded hardware designing with experience of 7 Years. I am a new member on Freelancer.in . You can count on me and if necessary have a chat with me for satisfaction.

I AM DOING ELECTRONICS ENGINEERING AND I HAVE DONE SUCH PROJECTS BEFORE WOULD BE REALLY IN NEED OF SUCH PROJECTS TO START MY NEW FREELANCING CAREER AT BOOST ! LET ME DO YOUR JOB TO GET THE BEST OPTIMUM CIRCUIT DESIGNED !
