BMS10x0

6 www.roboteq.com Version 1.0 March 2, 2018

The CAN and RS485 pins can be connected to a twisted pair cable. The BMS can be

conﬁgured to operate in either of these communication modes.

Two Open Drain Digital Outputs are availalbe for connecting low-power accessories.

The BMS10x0 also implements a RoboteQ proprietary single wire PWM communication

protocol for exchanging the most vital battery information with RoboteQ’s motor

controllers. When using the PWM mode, external ground and 5V supply must be

connected to the GND and VCC pins. (See MultiPWM in BMS operation)

Push-Button and LEDs

One push button and three LED indicators are provided for quick diagnostics such as

charge level, communication, and other useful information. Different ﬂashing patterns are

used to code the various information type.

USB Connector

A USB port is present for connecting the BMS to a PC running the dedicated PC Utilityfor

conﬁguring the BMS’s various parameters (voltage, current, temperature thresholds, etc.),

monitoring real time operating values, capture/save logs and editing user scripts.

Pack+/Pack-Battery Connection

The Pack+ and Pack- are high-current screw terminals connected to the battery pack’s

mains; positive and negative. Current up to 100A can be transferred to the battery

during charge or regeneration and from the battery during discharge. A 16-pin connector

on the BMS10x0 is used for connecting each individual cell’s terminals for monitoring

and balancing.

Temperature Thermistor Connector

The 6-pin connector provides the connections to up to three external 10K NTC thermistors

for monitoring temperature in the battery pack. Thermistors can be connected without at-

tention to polarity. Use Molex 2 rows x 3, 4.2mm pitch connector reference 0039012060,

or equivalent..
