EV Electrical System Design Blueprint house battery for mobile office

An all-electric vehicle is about to receive a full custom upfit and I need a complete engineering blueprint before a single wire is pulled. The scope centers on design and planning only—no on-site installation is required at this stage. Vehicle • Platform: Electric Vehicle (EV) - Chevrolet Brightdrop 600 cargo van Systems to be integrated • 48v 100 Ah House Battery Management System (BMS) • Shore Power Charging & house battery to/from vehicle charging option • High-power (3000+) 48v DC/AC pure sine wave inverter feeding 120V house circuits • Secondary LiFePO4 (or gallium/GaAs semi-solid state) 20 Kwhr house battery bank with proper isolation from the traction pack • Roof-mounted ETFE N-type/P-type monacrystalline 300 Wh/kg flexible solar array and MPPT charge controller tied into the above Data feed - tri-band dual SIM bonded router & Ext MIMO antenna Audiovisual - external/internal noise cancellation and layered dynamic sound integration & With What I expect from the finished package • Single-line and detailed wiring diagrams showing conductor sizes, fuse/breaker values, grounding, and disconnects • Component specification sheet (models, ratings, data-sheets links) with justification for each selection • Load and energy-flow calculations covering worst-case driving, charging, and office loads • BMS architecture chart outlining cell tap layout, balancing strategy, and CAN data mapping • Compliance notes touching on NEC, SAE J1772, and relevant UL standards • File delivery in PDF plus native CAD (DWG, SolidWorks Electrical, or similar) I already possess rough sketches and target performance data; once the NDA is in place I will forward these along with battery and motor specs. A collaborative approach is welcome—quick design reviews over video or shared whiteboard will keep the project moving smoothly. Final acceptance hinges on diagrams that can be handed straight to a certified installer without further clarification.
