I need to make a project for 2 types of LED-drivers: 30W and 72W Power supply is in both cases a battery pack eg. BOSCH 18V/2Ah or 18W/5Ah. T...18V/2Ah or 18W/5Ah. There is no AC power supply, nor battery charging function. Both drivers need to have automatic signaling of low power in the battery and switch to an emergency function mode (low light output eg. 10%). Normal functioning should be possible at 3-5 output levels: 30/50/75/100% or similar and selectable using a momentary switch. The driver circuit witll be connected with an external BMS between battery and driver. Driver-output is not fixed yet, it depends on the IC and topography, the target is efficiency >90%. The circuit must be thermally protected and automaticaly dim light if overheat is detected. Max development ti...

need to make a circuit bored that runs the length on the battery 25mm wide and approximately 260mm long ( can be wider if cheaper than multi layer voltage between traces is under 5v and over all voltage is under 60v wide with the 15 ballance connections on it along with ptc fuse for 250ma on the end it will need cells 1-14 in sequence with holes for the balance wires to go from the bms to the circuit bored ideally the fuses need to be close the the battery connections to make the fuseing effective idea would be to run the bord on the side of the pack and connect each group of cells via nickel strip soldered to the bored and spot welded to the cells can provide exact diamentions once I have somone that can help

We need to optimize our design for mass production. We have fully tested BMS power board(160x130mm). You should change some connectors into Molex type, combine some connectors, optimize board size, which means that you don't need to work on schematic but you should modify PCB layout and update BOM file. This project is kind of urgent, I'm hiring someone in 24hrs and this task needs to be done in 1 week. If you are successful in this project, there will be another similar projects late this month. I'm attaching image for the current design. The deliverables should be: Overall Schematics and PCB files for production BOM 3D CAD drawing of PCB Board Documentation (e.g. pin definition of connectors) We will share existing PCB design during further discussion.

Hi Daniil R.I noticed your profile and I see you have done things similar to what I need for my project. It will be a fun project. I am trying to build a high performance e-bike but I do not have enough knowledge to do it all by myself in the way I would like it to be. Where I need help the most is with hardware and software design of "active hybrid" battery pack which includes lithium ion and ultra capacitor combo in order to achieve almost instant charges and discharges. This way, it should be possible to achieve maximum performance as well as to "catch" maximum energy back with regenerative breaking. In order to do this, there has to be good battery management system which will include thermal battery management with active and passive liquid cooling system, a...

The logo will aso be 3D printed or molded, so any connections with other freelancers you have worked with or do yourself, to torn the logo into a flat emblem that will attach to the front of the golf cart.
