Battery

BMS1: Killswitch works

• flash smoke_bms

• latch the killswitch, should log an interrupt on minicom with the correct state

• unlatch the killswitch, should log again

• shake the killswitch and repeat a few times to ensure connections are good

BMS2: 1 AFE Vsense works

• in the battery mockup, connect one AFE’s cell power wires

• flash smoke_afes and set it to just one AFE

• observe voltages on minicom

• verify at least one cell voltage with a multimeter

BMS3: All AFE Vsense works

• repeat BMS2 procedure with all AFEs connected and enabled in the smoke test

• verify at least one cell voltage per AFE with a multimeter

BMS4: 1 AFE temp sense works

• make sure thermistors are connected to AFEs

• repeat BMS2 but with temperature

BMS5: All AFE temp sense works

• repeat BMS3 but with temperature

BMS6: Cell balancing works

• setup for BMS3 but enable cell balancing in the smoke test

• note the difference between the highest and lowest voltages for each AFE

• wait 5 minutes

• verify that the difference between the highest and lowest voltages has decreased in magnitude

BMS7: Current sense works

BMS8: Battery fans work

BMS9: Relays work

• flash smoke_bms

• by default the relays should be enabled

• when powering on the board with the code flashed, an audible click should be heard from the relays closing

• verify continuity on the relays with a multimeter (the two leads on the top of each relay should be continuous)

C1: MCP2515 works

C2: Connection sense works

C3: Control pilot works

C4: Elcon comms works

SO1: Front vs. rear identification works

• flash solar on both the 5 and 6 mppt boards

• ensure that the appropriate number of mppts is logged on minicom for each board

SO2: 1 MPPT SPI works

SO3: All MPPT SPI works

SO4: Array temp sense works

SO5: 1 MPPT MCP3427 works

SO6: All MPPT MCP3427 works

SO7: Isense MCP3427 works

SO8: Relay works
