Multiple LiPo battery charging electronic design

Hello! I have experience in charger for Li-ion and in the Battery Manegment System (BMS), which included charge balancing features. In particular, our team has developed a charger + BMS for 10 in series Li-ions, max current 10A. I am ready to discuss the details of the project.

Hi Sir, We have already designed battery management systems with keeping in mind following over voltage protection over current protection charge balancing fault detection etc. we are agreed to you on point a-f Lets talk to us on this. We are professional engineers and developers who do such projects from the last 10 years. We offer you our skills for this project at very low rates comparatively without compromising the quality of work. Let me introduce you to our company TURKTRONICS. We are TURKTRONICS. We are team of professionals with 10+ years of experience in Circuit designs, PCB designs, embedded system solutions, mobile app development, programming and software development. We provide complete end to end solutions for all kind of development projects. IOT is our strong point. In this bid, prototyping and shipping cost is not included however paying extra slight of money to include prototypes. We have the manufacturing facility and we produce the very high standard PCB boards and send ready products to customers doorsteps via DHL. We care about our clients and help them to get out of any potential problem throughout the projects and also give post completion technical support if ever required. We are very much looking forward to hear from you on this in coming days! Cheers!!! Ahmad Lead Technical Engineer TURKTRONICS An Internet of Things Company !

Hi there I am an electrical engineer with 8+ years of experience. I have experience LiPo battery charging. I have designed many multi-cell battery management system . I can provide you demo videos of our previous battery management system works

Hi My name is Vusi and I'm an Electronic Engineer, you can learn more about me from my Freelancer Profile.

Hi! Your project looks to be an interesting an interesting challenge to do. Lets go trough your requirements: 1. If do you want to charge up to 16x Li-Po batteries, so formally you need a 16S charger, what could be achieved by combining 4x 4S charging channels, for example, or any other combination up to a single charge controller with 16x channels. 2. The charging is stopped when reaching the minimum current consumption of the charge circuit, what is settable, at this level the batteries will have the voltage level of the fully charged battery. 3. The measurements could be done by a LTC6804 like battery management IC and the values read by a given microcontroller like STM32Fx series. a) this is via the battery management by microcontroller; b) could be done via individual battery connection mechanism to be able connect the batteries to the charger and disconnect them in fault conditions, for example; c) the MCU (microcotroller) can send such kind of information to the host according to the voltage reading data; d) this is related to a) e) do you want to implement a discharge circuit as well? How do you planing to connect the charger to a host system, so what would be the communication interface?

We are experts in handling LiPo batteries, we can perfectly design a charger circuit with balancing option to balance all cells, as well as overcharge protection. Hire the BEST, forget the rest.

Sir, Its me imad, Already did a lot of work on lithium ion batteries and implemented a research within the matlab, Although your batteries are LiPo i m ok with them,,,,in order to make a software for complete monitoring and control for ur battery charging system is an easy task,,,,i will make it done wireless,,,,,,As per the charging circuitry is concerned, i will rely on prexisting one as they r tested and reliable as well,,,thanx,,,

Hi, We could design a multiple LiPo battery charging electronic design. I just came across with your requirements. We are a professional team in Embedded system having proficiency in Hardware & Firmware development. You can review our PCB design work in our portfolio:- https://www.freelancer.com/u/intellisenseIN We will be glad to hear from you! Regards, Intellisense Technology

Dear Sir, I am an experienced embedded system developer. I have expertise in designing PCB as well as programming microchips. I would like to provide my full effort to design a perfect hardware device for your project. Best Wishes

I been working on battery related products for quite a while now. I have designed a battery management system for solar, Electric Vehicles and also for handheld devices. And since you have a 4s battery pack I can easily design it for you. I ll be using an robust microcontroller with fail proof algorithms to control the current using mosfet. Also regarding the communication to the system for information I can build you a module which you can connect to the BMS and you can get all the battery related info either on the cloud or simply on a mobile phone using an andorid app. I would be dedicated towards the work offered and the quoted prices would be reasonable. Would love to hear back from you!

I don't want to say who am I and all. Coming to your project it seems to be a simple BMS which would be based on ARM cortex to make it more reliable and if budget is not allowing you it can be done on Arduino as well. Here we have to work on Newton charge method which will gives you your battery information which would be read by your controller and it can be send directly to its destination and hence this is the simple project if we cut into small pieces and the join Thanks

Multi charger design will have common AC-DC circuit and individual DC-DC converter along with charge control and management IC. Each management IC communicates with master controller and throw data to display and communication port. Send a message to discuss block diagram.
