R230 Auxiliary Power Control Module (BCM Replacement Solution)

Engineered Alternative to OEM BCM Failure with CE-certification, E-automotive mark and RoHS

Failure of the original auxiliary Battery Control Module (BCM) is a known issue on the R230 platform.

When the BCM fails, common symptoms include:

• Red battery warning on the dashboard

• Deactivation of auxiliary systems

• Charging irregularities

• Expensive replacement recommendations

Nee OEM modules often exceed €2,000 and used units carry significant risk due to age and repeated failure patterns.

Where the EverDrive module stands out!:

• Improved design for power transfer by using brass leads instead of steel. The surface area has increased to 20mm2 from the original 10mm2 significantly improving power loss and heat generation 
• Fuses on the main leads to protect the board against overconsumption
• In rest  other solutions consume at least 20mA and slowly drain your battery. EverDrive uses the CAN wake-up line to power the module so at rest 0.0mA and no drain.
• Remote emergency start which allows on a press of the button to connect both batteries to allow crank on low batteries for 15s only. Preventing overheating. 
  
• No additional wiring needed- 4 mounting screws and the original connectors. DONE. 
  
• The only true plug and play replacement.
  
• Full unit IP67 dust and waterproof which is essential. 
• Any existing boards are well over 20 years old, sometimes repaired units. The design flaw remains often induced by moisture in the trunk. The Everdrive unit is IP67 moisture rated.
• Full business environment, order with confidence a unit with CE certification, RoHS

This solution provides a structured and modern alternative.
