Dear Sir, I will use battery management system IC's and design guide from Texas Instruments for this project. because they always provide a good design guide as well as other related documents, so we can refer and applied it to this system. I have used several of their power management products and it always comes with propper design guide. I have became PCB designer since 2012 and has done lot of projects for various application from Hobbyst, Robotic, Industrial, IoT, Audio, and Military purpose. I have experience in Desigining advanced circuit like high speed digital communication, differential pair, mixed signal, on board antenna, switching power supply, isolated I/O, etc. let me help you design this project, I have experience on it as well as knowledge background behind it. let's work together. Best Regards, Rijal

Are you planning to design a device that consists of mechanical parts, a PCB, a plastic enclosure or even a composite material? If so, I'm here to help you! Since I'm an Electromechanical Engineer, I'm proficient in Mechanical, Electrical and Electronics projects which means I can design a device from scratch or even have a final review of your work. I suggest you take a look at my project "A device for swimmers!". This is an open project with the sole objective of showing some of what I can offer. I own a small shop, so I'm also offering prototyping services and prove of concept of a certain device. I'm always available to answer even the simplest questions, can work with flexible budgets and I would love to hear your idea. Over 13+Years of Experience in System Design in various Domains Like Power Supply, Consumer Electronics, Telecom, RF Boards. Working on High Speed Designs, Impedance Matching, Delay Tuning, Differential Routing, Hands on Experience in Xilinx(Saturn, Vertex), Altera(Cyclone) FPGA, DDR2, DDR3 PCB Designs. Iam providing PCB Design Services. Including schematic capture, BOM generation, PCB layout if need board procurement, Solid Works mechanical Housing design Please see below, Iam supporting following PCB design tools. • Mentor Graphics PADS (VX2.2, 9.5, 9) • Altium Designer (10, 2014, 2015, 2016, 2017) • Cadence Allegro 16.6 • Mentor Expedition PCB (EE2007) • OrCad Layout Plus (15.7) • Eagle (7.6) • Auto Desk Eagle (8.0.1) • Protel SE99 • KIcad..

Dear, We are a Argentinian company that have more than 7 years of experience in embedded programming, PCB's design with KiCad and industrial electronic systems implementation. And we have alliances with local and overseas partners for mass production. We can make the PCB and schematic design using KiKad and PCB assembly (We have SMT and soldering lines for small quantities prototype productions). We have a lot of experience in cellphone chargers, battery chargers, motor control, H bridges (1 and 3 phases), etc. We can develop the complete solution, mechanical design and drawings, PCB design, PCB assembly, firmware programming, and machine assembly. This Bid proposal is only for PCB (schematics, PCB layout, and Gerbers). Programming, KiCad is an open source software suite for Electronic Design Automation (EDA). The programs handle Schematic Capture, and PCB Layout with Gerber output. The suite runs on Windows, Linux and macOS and is licensed under GNU GPL v3. Thanks you Leonel Caraccioli OpenMolo

I am working in the field of Electric Vehicle for quite some time now. I have made MATLAB models of battery pack cell balancing and protection circuitry. Judging from the specification provided, I assume that you do not have a ready component list and schematic design. Having worked in the field, I know that this is not a 3-day task as suggested by some earlier bids. These are the tasks required for successful completion of the project 1.) Topology selection for Cell Balancing, Current/Power limiting 2.) Microcontroller Selection depending on the number of switches and peripherals to be used. 3.) Component Selection (for lower overall cost) 4.) Design and Simulation of circuit 5.) The schematic design on Altium Designer 6.) PCB Design on Altium Designer I have some questions about the project: - What is your timeline for the project? Is the circuit going to be used as in a project or a product? (for quality assurance) What is the expected circuit board cost? Please reply with any of your queries.

Hi Mate, Firstly.....it is the battery suppliers responsibility to provide the PCB for you for power management when buying a completed battery. . Therefore I assume you are buying the cells yourself and want to assembly them yourself. I am based in Shenzhen China and I have almost 7years dealing with lithium ion batteries and can finish this project for you. Thanks Kevin
