MES / CEBI TIM

Using a MES / CEBI TIM motor inverter with an Lithiumate BMS.

Wiring anchor

Connect the BMS and the inverter through the CAN bus.

back to topConfigure the Lithiumate Pro BMS

In the GUI, go to the "Configure" tab, the "Communicate" sub-tab, the "Message to devices" box, the "Motor driver" box, and select "MES TIM".

back to topConfigure the TIM inverter

The TIM inverter does not need any configuration to work with the BMS. However, note that the default CAN bus speed for the TIM is 125 kbps, while for the BMS it is 500 kbps. The speed for both devices can be changed, but it would probably be easiest to change the TIM inverter to 500 kbps.

back to topCAN messages

If enabled (see above), the Lithiumate generates the following message for the MES / CEBI TIM series motor inverters.

Notes:

  • Multi-byte values are little-endian (Intel standard): the LSB (Least Significant Byte) is in the lower numbered data byte (the left most byte in the following tables)
  • The default bus speed is 500 kbps
  • Period from BMS controller: 100 ms (MES specifies 135 ms, minimum and maximum period are unknown)

Notes:

  1. Minimum battery voltage, 0 to 900 V [0.1 V]. Same as the Minimum Pack Voltage setting

  2. Maximum battery charge current, 0 to 900 A, positive value [0.1 A]
  3. Flags:
    • Bit 1: 1 to enable charging; 0 to disable charging. Controlled by HLIM
    • Bit 2: 1 to enable discharging; 0 to disable discharging. Controlled by LLIM
