The BMS will be used for Lithium battery in size of 5 - 10 kWh (12 or 24 V) and current of max 500 A, i.e. needs external contactors. Previous experience of PCB as BMS design is required. The project starts with requirements of features and the assignment will result in designed PCB ready for testing (we will perform tests). The BMS design should be much of the basics, passive intelligent balancing, LVP and HVP that are handled by two external contactors. BMS will manage 4 or 8 LFP cells. But we also want some special features like; extra (second) LVP triggers with time delay, external power supply (12 or 24 V) and when off, there must be zero consumption (current) from BMS. BMS doesn't need to measure current, SOC calculation nor CAN communication. If interested, please post previous experience, type of project and date. We also appreciate a indicative quote for project with requirement as above. If we start a discussion, we will email all details and request a valid quote. Company is based in Sweden. Please note, we have not disclosed our budget for this project.

3 weeks ago, I had similar project for US client. It was hybrid powering system involving 7A battery, 900W gasoline generator, 12kW DC motor. I had designed autonomous battery management system having LVP, HVP and used voltage sensor, current sensor, Arduino and some relays. Project was verified via testing. I think your project is very similar in many cases. I am an expert in circuit design, PCB layout and firmware programming. I have strong experience in power electronics, battery management and power bank design is my strong point. My former projects in power electronics are as below. + 10kW grid tie solar power inverter + 3kW CVCF(SMPS) + 10kW voltage stabilizer(transformer type) + 7kW welding machine power supply + 1kW battery charger + 48V/50A DC power supply ... I will share previous design files via chat since I can not upload any file on this bid. Looking forward to having opportunity to discuss on your project in detail. Thank you.

Dear Sir/Madam, We are an electric powertrain company in the UK and specialise in electric bike systems (motors, motor controllers and battery systems) mainly. We would be able to produce a fully assembled prototype PCB. This look like a interesting project and look forward to hearing from you. Kind regards, Hugo
