3. Design Features & Components
3.1 Integrated Battery Management System (BMS)
Monitors
• Cell module voltage
• Battery voltage
• Battery current
• Battery temperature
• Battery state of charge (SOC)
• Battery energy throughput
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 (
Win64
supported)
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 Battery 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 (Hardware version 0.0.0.1 models will sound a buzzer, but not flash the key LED). Most protections will
automatically recover once the condition is cleared with the exception of the low voltage protection.
Protection
Auto Recoverable
Description
Over Voltage
Yes
Protection is triggered when any cell module voltage exceeds the
threshold value for 5 seconds. After the voltage falls below the
trigger for 120 seconds the protection is cleared.
Under Voltage
No
Protection is triggered when any cell module voltage falls below the
threshold value for 5 seconds. The battery will turn itself off after 120s.
High Current
Yes
Protection is triggered when current exceeds the threshold value. The
protection will be cleared after 120 seconds.
High Temperature
Yes
Protection is triggered when the battery temperature exceeds the
threshold value for 5 seconds. After the temperature falls below the
recovery temperature the protection is cleared.
Low Temperature
Yes
Protection is triggered when the battery temperature falls below the
threshold value for 5 seconds. After the temperature raises above the
recovery temperature the protection is cleared.
4. Handling

WARNING!
Read Safety Section before installing the battery.
• 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
