Paid on delivery
Hello, I need a 2-Cells (500mA) Li-Ion Battery charger but also needs to have a battery State of Health (SoH) measurement. The SoH measurement coud be SPI/I2C/Analog/... The most important think to know is you have to put SOHM in the first and last line of your bid. And that the SOH measurement will be on the charger no with the battery so it has to be measured only when charging. Please feel free to ask me anything. Best regards for all, Lucia.

I am writing this proposal in order to work for you in Software and Web Development. We are highly trained professional developers seeking to freelance and earn online. Having a flair in programming and development I have been excellent with JAVA,C#,C/C++ and PHP programming language along with MySQL with XAMPP Server. I also build application for Cloud computing and High performance computing as I also have knowledge regarding Hadoop, MPI, OpenMP (distributed frameworks) and also have build applications in CUDA C++ and OpenCL. I also have experience with the most famous framework ASP.NET. My most expertise are in JAVA where I have built countless projects for semester projects and Final year project. You may find many developers in this field however we assure that you will not be able to find a team like us. We not only ensure the code is quality wise but we also assure that the code we write are optimised and we ensure that the program performs right operation under right environment i.e. we create programs that are defect free. You may also find freelancers that cost low but they do not put their 100% which then shows in the software and leads to an unhappy customer.

I am an electronics engineer with experience of 17 years of which 10 years of experience in embedded electronics. I have worked with 8051, PIC, AVR, dsPIC, PIC24, PIC32, STM32, Tiva, Stellaris, Arduino, MSP43x, FT90x, RISC-V microcontrollers. I have all licensed software to code a project. I have a lot of high-end embedded development boards and test equipment to successfully design and debug a product. I can help with your embedded project. I have designed many Battery Chargers from mA to A ranges. I can do your project within one day. I will do all the features that you have mentioned that is battery charger + SOHM, etc,... A PIC microcontroller will be used with Li-Ion Battery Charger Circuit. The Battery Voltage is monitord by a PIC microcontroller running from 1.8V. The circuit will be small. If you prefer LCD display then you can use any HD44780 compatible one and then I can use a 14 pin PIC microcontroller. The final product if designed using all SMD components will be a small PCB. Send a chat message so that we can discuss further.

Hello, I am happy to help you design the battery charger system, because I have done many projects using solar batteries and charging adapters for li-ion batteries (18650), LiFePO4 and Lead-Acid, These control systems feature automatic switching to the battery source when the solar panel is not sunny and the adapter loses power. My systems use Linear technology's charging solution, which uses ADC to monitor SoH batteries very efficiently and has a very long battery life. Best regards
