100A 48V Battery Protection - Victron Energy

Description

The BatteryProtect disconnects the battery from non-essential loads before it is completely discharged (which would damage it) or before it has insufficient energy left to start the engine.

Very easy programming
The BatteryProtect can be configured to disconnect or connect at different voltage levels. The 7-segment display will show which setting has been chosen.

Special mode for Lithium-Ion batteries
With this mode, the BatteryProtect can be controlled by the VE.Bus BMS.

Very low energy consumption
This is an important feature for Lithium-Ion batteries, especially after a low voltage shutdown. Please check our Lithium-Ion datasheet and the VE.Bus BMS manual for more information.

Overvoltage protection
To prevent damage to loads that are sensitive to overvoltage, the load is disconnected if the DC voltage exceeds 64 V.

Contamination current protection
No relay, but MOSFET transistors, and therefore no arcing.

Delayed alarm output
The alarm output will be activated if the battery voltage drops below the preset disconnection level for more than 12 seconds. Engine start-up will therefore not trigger the alarm. The alarm output is a short-circuit protected 50 mA open collector output that is connected to the negative rail. The alarm output is generally used to switch on a buzzer, a LED, or a relay.

Load disconnect and reconnect delay
The load will be disconnected 90 seconds after the alarm is activated. If the battery voltage rises to the connection threshold during this period (e.g. after engine start-up), the load will not be disconnected. The load will be reconnected 30 seconds after the battery voltage has risen above the preset load reconnections voltage.
