Design of PCB to Battery Management System

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.
