The device knows the difference between riding, charging, looking something up and setting something. Each mode shows what that job needs and nothing else.
Pack voltage, average and lowest cell, highest temperature, GPS speed and altitude, with a live bar for every cell in the pack while you ride. The weakest cell is always marked, and standard deviation across the pack is tracked so a drifting cell is visible before it becomes a problem.
Open the cells view for exact voltages, sorted or in pack order, with outliers highlighted at a threshold you set.
Every pack thermistor, with the count set for each vehicle, plus onboard air temperature, with motor, inverter and coolant alongside. A sensor that isn't fitted or isn't talking reads "No input", so you can tell a missing signal from a cold one.
Adjust BMS limits from a swipe panel, with safety bounds enforced by the interface. No laptop at the trailhead.
The DBB reads the EVCC's trace stream and the BMS at the same time, so a charge session is recorded from both ends: what the charger delivered, and what the pack did with it. Pack progress, live current, watt-hours delivered, and cell balance as it happens.
Leave the bike plugged in with the DBB powered and it waits. When the charger wakes the bike up, the DBB finds both devices and records the session without you tapping anything.
Every session stays on the device and opens right there. It's your data on the device, never in the cloud. Browse as cards or a list, open any session, and pan and zoom the graph. Default view overlays pack voltage, temperature, GPS speed and altitude; the all-cells view draws every cell and every thermistor for the whole session.
Both devices are configured from the touchscreen, with the interface enforcing safe bounds on every value. Rider profiles keep each bike's setup separate. Time comes from GPS, a phone or the calendar. Sessions export to a USB stick, and a diagnostics bundle of logs, settings and learning data copies out in one step when something needs a closer look.
The whole interface runs without a bike attached, on simulated data. Use it to learn the device, train a new technician, or show a customer what it does before a wheel turns.
