Rivian Auxiliary Power Unit System (APU) 12-Volt High Amperage / High Output Energy Supply Systems

When planning to upfit your Rivian with 12-volt accessories you'll quickly realize the lack of adequate onboard low voltage power sources. Although Rivian models are electric vehicles, they operate on a 400-Volt structure and use a small DC-to-DC converter to feed a very low amperage 12v sub-structure. The existing 12v sub-structure will not support auxiliary loads typical for most any upfit lighting, offroad, camp/cook, or adventuring equipment - and running extension cords and converters to the 120v AC ports just doesn't work well. Overloading the OEM Rivian 12v circuit will cause the circuit to shut off (digital circuit breaker) and trigger service errors. Worse yet, when the low voltage circuit fails or shuts down, the Rivian bricks - inoperable and in most cases doors / windows are closed and locked until the low voltage system is properly trickle charged back to a minimum threshold. Additionally, any attempts to hack a secondary DC-to-DC converter directly to the high voltage battery will be limited to operating only when the Rivian is 'on', or by trying to trick the Rivian into staying on -- these are far from fool proof and robust solutions, along with being risk to OTA update obsolescence. Rest assured, the engineers at EV Sportline have developed a proper high-amperage, low voltage auxiliary power unit system (APU) specifically for Rivian integration. The APU was engineered from the ground-up for Rivian upfitting power supply, in order to provide a nominal 12.8-Volt, 100 amp auxiliary power source in full cooperation and compatibility with the OEM high voltage structure. The APU is a bolt-in solution, supported directly by the Rivian OEM low voltage power circuit, without any risk of triggering errors or circuit trips on the OEM circuits. The APU is also able to be powered on and left on, independent of the Rivian run mode - there is no need to turn the Rivian on, nor any need to trick the Rivian into entering or remaining in Drive mode. Further, there is no direct integration with the 400-volt system, so no dangerous installation or high-voltage training certification is needed to install the system. Contact us for special assistance retrofitting old / other Rivian upfits to improve reliability and performance. Each APU system includes a remote mount monitor gauge, allowing operators to view system status, run time and power levels. These systems are custom 'built-to-order', please allow 3-5 weeks for delivery Installation is advanced DIY, this system expects you're comfortable and competent installing or having a professional installer handle it.
