Smart BatteryProtect
Protects the battery from deep discharge and can be used as a system on/off switch
The Smart BatteryProtect disconnects the battery from less important loads before it is fully discharged (which would damage it) or before it no longer has enough energy to start the engine. The on/off input can be used as a system on/off switch.
Bluetooth: simple programming
Using Bluetooth to program the Smart BatteryProtect, all required switch-on/switch-off thresholds can be set. Alternatively, one of nine preset switch-on/switch-off thresholds can be set using the programming pin (see manual). The Bluetooth function can be switched off if required.
A special setting for lithium-ion batteries
In this mode, the BatteryProtect can be controlled by the VE.Bus BMS. Note: The BatteryProtect can also be used as a charge disconnect between a battery charger and a lithium-ion battery. See the connection diagram in the manual.
Extremely low power consumption
This is important for lithium-ion batteries, especially after switch-off due to a low voltage level. Please also refer to our lithium-ion battery datasheet and the VE.Bus BMS manual for further information.
Overvoltage protection
To prevent sensitive loads from being damaged by overvoltage, the load is always switched off whenever the DC voltage exceeds 16.3 V or 32.6 V.
Explosion protection
No relays, but MOSFET switches instead, meaning no spark formation.
Delayed alarm output
The alarm output is activated when the battery voltage remains below the preset switch-off value for more than 12 seconds. Starting the engine therefore does not trigger the alarm. The alarm output is a short-circuit-protected open-collector output connected to the negative (minus) rail. Max. current 50 mA. The alarm output is normally used to activate an audible signal, an LED or a relay.
Delayed load disconnect and delayed load reconnect
The load is switched off 90 seconds after the battery voltage drops below the preset threshold. If the battery voltage rises back to the reconnect threshold within this period (for example after the engine is started), the load is not switched off. The load is switched back on 30 seconds after the battery voltage exceeds the preset reconnect threshold.
