3. Design Features and Components

3.1 Integrated Battery Management System (BMS)

Monitors

• Cell module voltages

• Battery voltage

• Battery current

• Battery temperature

• Battery state of charge (SOC)

Module Balancing

• Performs balancing of cell modules

Protection and Operating Limits

• BMS will open its internal relay when maximum operating limits are exceeded

• When the condition returns to its nominal operating range, most protections will be released and reset after 120s

Communication Ports

• Isolated USB and CAN communication

Data Logging

• Logged data is accessed using AES Dashboard software via the USB port

3.2 Internal Battery Fuse

The internal battery fuse provides back-up over-current protection. External fusing should be sized correctly to protect the circuit

and circuit cabling.

•

A blown fuse requires replacement by a qualified installer - contact your Discover installer.

3.3 Protections

The BMS will open the internal relay to protect against operation outside of maximum specifications. During a protection the key

LED will flash at 1 Hz. Most protections will be automatically recovered once the condition is cleared with the exception of the

low voltage protection.

4. Handling

• Battery should be set to OFF

• Battery cables should be disconnected

• Battery terminals should be protected

• Battery handle should be used to lift battery

• Battery should be handled by two people or mechanical lift equipment

• Do not lift or carry the battery during usage or operation

• Do not lift the battery with the battery cables

Auto Recoverable

Protection is triggered when any cell module voltage exceeds the

Yes

threshold value for 5 seconds. After the voltage falls below the

trigger for 120 seconds the protection is cleared.

Protection is triggered when any cell module voltage falls below the

threshold value for 5 seconds. The battery will turn itself off after 120s.

Protection is triggered when current exceeds the threshold value. The

Yes

protection will be cleared after 120 seconds.

Protection is triggered when the battery temperature exceeds the

Yes

threshold value for 5 seconds. After the temperature falls below the

recovery temperature the protection is cleared.

Protection is triggered when the battery temperature falls below the

Yes

threshold value for 5 seconds. After the temperature raises above the

recovery temperature the protection is cleared.
