BatteryProtect 48

Ultra- – low current consumption

This is important in case of Li-ion batteries, especially after low voltage shutdown.

Spec Sheet

Order Code: BatteryProtect 48V

Description

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

Features

Programming made easy

The BatteryProtect can be set to engage/disengage at several different voltages. The seven segment display will indicate which setting has been chosen.

A special setting for Li-ion batteries

In this mode the Battery Protect can be controlled by the VE.Bus BMS.

Ultra-low current consumption

This is important in case of Li-ion batteries, especially after low voltage shutdown.

Overvoltage protection

To prevent damage to sensitive loads due to overvoltage, the load is disconnected whenever the DC voltage exceeds 64 V.

Ignition proof

No relays but MOSFET switches, and therefore no sparks.

The alarm output is activated if the battery voltage drops below the preset disconnect level during more than 12 seconds. Starting the engine will therefore not activate the alarm. The alarm output is a short circuit proof open collector output to the negative (minus) rail, max. current 50 mA. The alarm output is typically used to activate a buzzer, LED or relay.

Delayed load disconnect and delayed reconnect

The load will be disconnected 90 seconds after the alarm has been activated. If the battery voltage increases again to the connect threshold within this time period (after the engine has been started for example), the load will not be disconnected. The load will be reconnected 30 seconds after the battery voltage has increased to more than the preset reconnect voltage.
