Shandoka DBB · Features guide
What the DBB does, feature by feature
The Digital Black Box reads your BMS and charger and shows every cell and
every thermistor on a 4.3-inch touchscreen, while you ride and while you charge. Here's
each part of it, with the device's own screens.
The Digital Black Box
See the cell that's about to cost you a pack
The DBB is onboard telemetry and logging for electric motorcycles. It reads the BMS and the charger directly and puts every cell and every thermistor on a 4.3-inch touchscreen, on the bike, while you ride and while you charge.
- Works with many popular BMS, charge management and EV drive systems, with more integrations being finalized
- Four gauges for pack voltage, average cell, lowest cell and hottest thermistor, with a bar for every cell beside them
- Every session saved on the device. It's your data on the device, never in the cloud
On the road
It speaks up mid-ride
When the BMS trips a cutoff, the DBB tells you which cell, how far past the limit it went and when, and an alert sounds. The ride keeps recording, so the whole story is there afterwards.
- Restart, Override or Acknowledge from the alert itself
- Faults are listed on the screen with how long each one has persisted
- After the ride, the idle screen shows the fault, the interrupted session and the pack as it is now
Ride · Cells
Watch every cell under load
The cells view gives the exact voltage of every cell with the weakest and strongest marked, and the spread across the pack. A cell drifting out of line shows up while you can still do something about it.
- Packs over 24 cells split into two rows, so a 40-cell pack fits on one screen
- The thermistor count is set per vehicle, and the log follows the pack
- Outliers are highlighted at a threshold you set
Ride · Temps
See which part of the pack is running hot
Every pack thermistor, the air, and motor, inverter and coolant temperatures on one screen. A sensor that isn't fitted reads "No input", so you can tell a missing signal from a cold one.
- Five zone colors carry state: nominal, good, advisory, warning and critical
- They stay distinguishable with the common forms of color blindness
- Critical is violet, so you won't mistake it for a brake light, and every zone also has a label and a value
Charge
Plug in and walk away
When the charger wakes the bike, the DBB finds the BMS and charger on its own and records the charge from both ends: what the charger delivered, and what every cell did with it.
- Current, power, watt-hours and charger temperature, live
- If one cell reaches the cutoff first, the DBB names it and flags that the pack needs a balance
- A summary and a graph of every cell when the charge ends. More on charge monitoring
Review · Replay
Every ride stays on the bike
Browse sessions as cards or a list and open any one on the touchscreen. The graph zooms and pans with one finger, and Replay plays a session back through the live screens as if it were happening now.
- Replay at 1x, 4x, 10x or 30x, with pause and 30-second skips
- The all-cells view draws every cell and thermistor for the whole session
- Sessions copy to a USB stick as CSV, with a diagnostics bundle in one step
- Months of sessions become a health history in DBB Desktop. See battery health that learns
Settings
Change limits without a laptop
BMS limits can be changed from the ride screen and charger limits mid-charge. The interface won't take a value outside safe bounds, and it shows you the profile limit as you get close.
- High, low and balance voltage cutoffs from a swipe panel while you ride
- Max voltage, max current, termination current and charge time while you charge
- Rider and vehicle profiles keep each bike's setup separate
Full · Lite · Demo
One device, three ways to run it
Full reads and sets. Lite watches only: it shows the bike's settings but can't change them. Demo needs no bike, and plays synthetic rides and charges through the real screens.
- Lite suits a customer's bike, a new technician or an install other people can reach
- Demo includes a ride where one cell sags on a long climb and the pack heats up around it
- Watching a battery bank instead of a bike? See remote battery monitoring
Shandoka · Detroit
From the shop that builds the bikes and trains the techs
Shandoka builds Multi-Fit electric conversions for classic motorcycles and trains the technicians who work on them. We built the DBB to see what our own packs were doing on the road.
V0.9-BetaTest · Waitlist
Join the waitlist, save $99
Early-release tester units are planned at $699. Everyone on the waitlist saves $99, whichever DBB they choose: an early-release tester unit now, or DBB Lite, Full, Pro or Desktop when they're released.
- Each tester unit is assembled and configured for your pack and charger, with your bike's profile loaded before it ships
- A direct line to the people who built it, and software updates as they're released
- 4.3-inch touchscreen, Raspberry Pi 4B, 12 V or USB 5 V with a LiPo backup, GPS, motion sensors and an air temperature sensor
