Sterling Power 12V to 12V Batt to Batt Charger 120A input Buck Boost

The Sterling Power BB12120 offers a cutting-edge solution for charging 12V batteries from another 12V source. Incorporating Buck Boost technology, this charger is designed to deliver high efficiency between 95-98%, ensuring minimal energy loss during the charging process. With a focus on simplicity and safety, the BB12120 is an essential tool for modern vehicles, including those with smart alternators and electric vehicles (EVs).

Key Features:

  • High Efficiency: Utilizes Buck Boost design for optimal energy conversion efficiency of 95-98%.
  • Versatile Compatibility: Fully compatible with smart alternators/Euro 6+ vehicles and suitable for electric vehicles, addressing the specific needs of newer car models.
  • Lithium Safe: Ensures safe charging for lithium-ion batteries, including a low-temperature trip to prevent damage in cold conditions.
  • Easy Installation: Designed for straightforward installation and setup, allowing for hassle-free integration into existing systems.
  • Multiple Charging Modes: Features ignition feed or Vibration Sense modes for flexible operation tailored to different vehicle setups.
  • Preset Battery Types: Includes 6 preset battery types, catering to various battery chemistries and requirements.
  • Comprehensive Protection: Offers 6 self-recovering protections to safeguard against potential charging issues.

Benefits with EV Installation:

  • Isolation and Protection: Isolates the EV's 12V battery from the leisure battery, preventing the EV battery from draining and ensuring the vehicle remains operational.
  • Optimized Current Draw: Configurable to draw only a portion of the DC-DC converter's output, allowing essential vehicle functions to continue uninterrupted while charging an auxiliary battery.
  • Correct Charge Voltages: Ensures that the auxiliary battery receives the correct charging voltages, adapting to the varying outputs of DC-DC converters found in different EV models.

Installation Advantages:

  • The BB12120 acts as a bridge between the high-voltage system and the 12V auxiliary battery, ensuring that charging is managed efficiently and safely.
  • By regulating the charge to the auxiliary battery, it prevents overcharging and potential tripping of the battery's BMS, especially in lithium-ion setups.
  • It adapts to the vehicle's power demand dynamically, reducing performance when the vehicle's ancillary loads require more power and resuming once the demand decreases.
