How to program the BatteryProtect

Posted by admin 01/09/2016 0 Comment(s) Battery Charging,

The BatteryProtect automatically disconnect loads to prevent battery damage or deep-discharge. 
In this video we will show you how to program the BatteryProtect and demonstrate how the BatteryProtect responds to under- and overvoltage.

 

 

BatteryProtect key features

  • LED display making setup/programming easy.
  • Often used in lithium systems due to low standby current in comparison to a relay.
  • Lithium system remotely controllable disconnect switch.  Note that this no longer uses its internal voltage measurement for disconnecting, as it is now remotely controlled by the BMS.
  • Ideal for vehicles, solar installations, boats and motorhomes.
  • Solid state switching for longevity.
  • Lower energy consumption than closing a relay.
  • Can act as a battery isolator and be switched remotely.
  • Use in conjunction with a BMV-700 series battery monitor for audible alarms and monitoring.
  • And why not use the VictronConnect app & Bluetooth Smart dongle with your BMV or  MPPT solar charge controller – making life even easier.

What does BatteryProtect do?

BatteryProtect will disconnect 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 an engine for example.
 
Here are the features common to all models:
  • Programming made easy using visual LED – can be set to engage / disengage at several different voltages. The seven segment display will indicate which setting has been chosen.
  • 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. Please see our Li-ion battery datasheet and the VE.Bus BMS manual for more information.
  • Over voltage protection – to prevent damage to sensitive loads due to over voltage, the load is disconnected whenever the DC voltage exceeds 64V; 16 V and 32V respectively for 12V and 24V systems.
  • Ignition proof – no relays but MOSFET switches, and therefore no sparks.
  • Delayed alarm output – the alarm output is activated if the battery voltage drops below the preset disconnect level for 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 50mA. 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.

Model Range

12/24V models

In addition to the features above (if choosing a 12/24V model) these have automatic detection of 12 or 24 V system voltages.

  • BatteryProtect 12/24V 65A
  • BatteryProtect 12/24V-100A
  • BatteryProtect 12/24V-220A

48V model

  • BatteryProtect 48V-100A

Conclusion

BatteryProtect is an affordable multi function product, which can be fitted to new systems or as an upgrade to old ones.
