Description

The Harmony 32 is a high-power BMS which can manage up to 32 cells in series for batteries discharging up to 600A. An on-board ESP32 micro-controller running open-source VESC Software enables precise real-time monitoring and balancing of individual cell groups. VESC Tool enables complete flexibly to configurable all the parameters of the BMS so that the battery can be operated safely. With a maximum charge current of up 30A and real-time monitoring of cells, the battery can be wirelessly monitored while waiting for the battery to charge. This BMS also features short circuit protection up to 600A with a 10µs response time.

Isolated CAN-bus connectivity allows for seamless integration with other VESC devices for effective communication between all devices in the system. Other communication methods include USB-C, Wi-Fi and Bluetooth for convenient and flexible options to connect, configure and monitor the device using VESC Tool.

Suggested applications include small electric vehicles such as E-bikes, electric motorbikes, go-karts, trikes and buggies.

It mainly depends on what the battery cells can handle rather than the BMS.  The BMS itself can take the same regen current as output current as it goes through the main power path.

Through the charging port it can only go up to the specified charge current.

Charge current, battery current, and battery regeneration current can all be individually configured using VESC Tool to suit your specific application, hardware or performance requirements.

Most likely the BMS has entered sleep-mode. Sleep mode is entered when:

  • Power is off
  • Nothing is connected over USB, Bluetooth or Wifi
  • Not balancing
  • Not charging
  • Block sleep is disabled in the settings

Notice that block sleep is enabled by default, but it will disable itself after a few hours to avoid draining the battery.
In sleep-mode it is not possible to connect to the BMS over USB, Bluetooth or Wifi. To leave sleep mode you can:

  • Enable the power output by bridging EN and ENs on the comm-port
  • Connect a charger

When changing CAN-mode to UAVCAN (DroneCAN) the VESC CAN protocol will be disabled. This means that VESC Tool can’t be used to configure and monitor ESCs or other VESC devices on the CAN-bus at the same time as UAVCAN is enabled. This is especially a problem on the Maxim, Pronto and Duet controllers as they access the STM32 using the ESP32 using VESC CAN. The later firmwares will therefore switch back to VESC CAN on reboot.

Earlier firmwares will not switch back on reboot, meaning that it is possible to lock yourself out from them (Maxim, Pronto and Duet) when changing to UAVCAN. If you have locked yourself out you can either try connecting using the UART-port with an USB-to-UART adapter and 115200 baudrate or you can use USB to reflash the STM32.

So, how do I use UAVCAN on Maxim, Pronto or Duet? Unfortunately we don’t have a good solution for that now. As it is now UAVCAN is not widely used among our customers (and VESC-users in general), but if it becomes more popular we will look into improving UAVCAN-support in the firmware. Pull-requests on github are always welcome of course!
