His plan the company building the vehicle are basing it all on 12v inverters and a huge LiFePO4 battery. The max load is about 5kW and averaging about 4kW or so. That is a range of A to A which is pretty ridiculous in a vehicle. I know people do crazier things with car stereos, but this is a commercial system that is expected to be very high reliability.
Kinda nuts. I asked if anyone considered 24v or even 48v as a technical buss to power all the sensitive gear. Far more manageable cabling, distribution, fusing, etc. The only thing that would seem to be a challenge is that I have not seen any 48v alternators that can be installed in the auxiliary accessory position on the engine. I have seen industry articles that car manufacturers are likely moving to 48v systems - but I don't see any commercial items on the market.
My Google-fu is either weak or they are a unicorn. Found one random, no manufacture one Amazon of all places - but I am thinking of a reputable brand with high-reliability. Maybe putting 2x 24v in series?

Standard delivered with Alpha Pro MB charge regulator for an optimal performance and longer-lasting batteries Using a Battery Mate or battery isolator in conjunction with an Alpha alternator makes it possible to easily charge two or three separate battery sets simultaneously.
TIP: A second alternator on the main engine, combined with a larger battery bank and inverter, could be an alternative for a generator. Alpha alternators are equipped with several fixations for customised alternator brackets, available from your installer or engine supplier.
Some engine brands come with Mastervolt alternator brackets as an option. Standard alternators only supply the specified capacity at a high rpm. The Mastervolt Alpha alternator is specifically designed for powerful charging, even with a low engine rpm.
Forced cooling by fan operation of the pulley provides a lot of power in higher temperatures, especially close to the engine. For all engine types Alpha alternators are equipped with several fixations for customised alternator brackets, available from your installer or engine supplier.

It is good to clean any visible corrosion, but it is also necessary to perform a voltage drop test between the battery cable terminal at the battery and the opposite end of the same cable. See the Support section for a charging systems troubleshooting guide.
Warning: Never disconnect a battery cable while the engine is running to "test" the alternator. Doing so can cause high voltage spikes that can damage the alternator as well as other electronics. Only Bosch offers this value-added emergency roadside assistance program.
This exclusive Bosch service is available 24 hours a day, seven days a week, anywhere in the United States or Canada. Bosch units are specifically engineered and built to deliver the same or better starting and charging power as the original equipment units they replace. Every component used to build Bosch Alternators and Starter motors are subject to the same rigorous Bosch Original Equipment quality standards.
When installing an alternator, the battery should be fully recharged before vehicle use. Without a fully charged battery the alternator is being overly stressed asking it to do a job it was not designed to do.

The integrated motor-generator IMG Gen3 provides electric propulsion to the vehicle in its function as a motor, while in its capacity as a generator it converts mechanical braking energy into electrical energy. The third-generation IMG's high torque and power density provide electric propulsion for plug-in hybrid vehicles. Sinceit has been in use in production vehicles.
In motor operation, the stator generates an electromagnetic field which causes the rotor to rotate. The rotor's torque is transmitted to the transmission shaft by a mechanical linkage and provides propulsion. During generator operation, the rotor's permanent magnets generate a rotating magnetic field inducing alternating current in the stator. That way, the rotor's kinetic energy can be converted into electrical energy. The modular eAxle is a compact, cost-attractive electric drive solution for battery-electric vehicles and hybrid applications.
