Modular BMS
Det BMS (Battery Management System) vilket används på soffan är Jonathan Locks egendesignade Modular BMS-projekt. PCB-design, kod samt dokumentation för dessa finns att tillgå från hans GitLab repository.
Discosoffans batteripack är på 5-celler seriellt (5S). För detta behövs en modul per cell, varav en är master.
Följande är de konfigurationer Discosoffans BMS-moduler använder. Dessa anges i config.h.
/** @brief Voltage which gives 100%-active discharge output [volt]
* Voltages above this value will also keep the discharge output fully on */
#define VTHRS_DISCH_MAX_V 4.00
/** @brief Voltage which gives 0%-active discharge output [volt]
* Voltages below this value will also keep the discharge output fully off */
#define VTHRS_DISCH_MIN_V 3.95
/** @brief Threshold voltage for activating the charge-disable output [volt] */
#define VTHRS_CHGDIS_START_V 4.05
/** @brief Threshold voltage for de-activating the charge-disable output [volt] */
#define VTHRS_CHGDIS_STOP_V 4.00
/** @brief Threshold voltage for triggering an undervoltage alarm [volt]

#define VTHRS_UV_ALARM_V 3.50
/** @brief Threshold voltage for triggering an overvoltage alarm [volt] */
#define VTHRS_OV_ALARM_V 4.10
/** @brief Voltage hysteresis for leaving alarm state [volt]
* To leave the undervoltage alarm the sampled voltage must exceed

Questions
How big is the Motor driver PCB?
It measures 231.6 × 160 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Motor driver use?
156 parts, built around the NE555. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Motor driver KiCad files?
From the ETAChalmers/Discosoffa repository on GitHub, at the commit this page was made from: the board is electronics/motor_driver/motor_driver.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Motor driver design in my own project?
Its repository states no licence, so its author keeps all rights: ask ETAChalmers before reusing the design.
