Land Rover Discovery: Battery monitoring system

The Intelligent Power System Management (IPSM) continuously monitors the condition of the main vehicle battery.

If excessive battery discharge occurs, the system will begin to shut down non-essential electrical systems in order to protect the battery.

If the IPSM calculates that the battery's condition is not within the set parameters, there are 2 levels of action which can be taken. Both levels have an accompanying message on the Touch screen, and in the case of the low battery warning, in the Message centre.

  • Energy Management: Will be displayed on the Touch screen if the engine is not running, and system features are causing excessive battery discharge. After 3 minutes, the IPSM will begin shutting down the vehicle's systems. Normal system operation will resume when the engine is started.
  • Low Battery - Please Start Engine: Will be displayed on the Touch screen and in the Message centre if the engine is not running. After 3 minutes, the IPSM will begin shutting down the vehicle's systems. Normal system operation will resume when the engine is started.

Only start the engine, if it is safe to do so.

Note: If the message Low Battery - Please Start Engine is displayed, drive the vehicle for at least 30 minutes in temperatures above 0ºC, or at least 60 minutes if temperatures are below 0ºC.

This will allow the battery to recover to an acceptable level. If normal system operation is not resumed when the engine is switched back off, the battery may not have been sufficiently charged. If safe to do so, restart the engine. If problems still exist, contact your Retailer/Authorised Repairer.
