Smart alternator compatibility

Vehicle manufacturers are now introducing smart ECU (Engine Control Unit) controlled alternators to increase fuel efficiency and reduce emissions. Smart alternators deliver a variable output voltage and are shut down when they’re not needed. The converter has a engine running detection mechanism. This prevents the converter from discharging the starter battery when the alternator does not supply power. The Orion-Tr Smart Isolated DC-DC charger separates the starter battery from the service battery when the engine is not running.

Adaptive 3-stage charge algorithm:

Bulk - Absorption - Float

• Bulk - During this stage the controller delivers as much charge current as possible to rapidly recharge the batteries.
• Absorption - When the battery voltage reaches the absorption voltage setting, the controller switches to constant voltage mode. For lead acid batteries it is important that during shallow discharges the absorption time is kept short in order to prevent overcharging of the battery. After a deep discharge the absorption time is automatically increased to make sure that the battery is completely recharged. For lithium batteries absorption time is fixed, default 2 hours. The fixed or adaptive mode can be chosen
  on the battery settings.
• Float - During this stage, float voltage is applied to the battery to maintain it in a fully charged state. When the battery voltage drops substantially below this level, due to a high load for example, during at least 1 minute, a new charge cycle will be triggered.
• Flexible charge algorithm - Programmable charge algorithm, and eight pre-programmed battery settings are configurable within the VictronConnect app.
  

Remote On-Off

Use the remote function to enable and disable the converter remotely with the remote on/off connector or using the VictronConnect app. Typical use cases include a user operated
hard wired switch and automatic control by for example a Battery Management System.

Electronic Protection
