PRODUCT REQUIREMENTS DOCUMENT (PRD) Fleet Depot Charge Point Management & Energy Orchestration Platform Version: 1.0 Owner: Founder / Product Lead Market: Europe (initial focus) Target users: Fleet operators, depot managers, charge point operators, logistics companies, municipalities --- 1. PRODUCT VISION Build the most advanced Charge Point Management and Depot Energy Orchestration platform for commercial electric fleets (buses, eHGVs, eLCVs). The platform will guarantee vehicle readiness, optimise depot energy usage, autonomously manage charging infrastructure, and support multi-operator commercial charging with integrated payments and settlement. This system becomes the central intelligence layer for electric fleet depots. --- 2. PRODUCT OBJECTIVES Primary objectives 1. Ensure all fleet vehicles reach required SoC before scheduled departure. 2. Optimise depot energy usage within grid constraints and tariffs. 3. Enable third-party/subcontractor charging with billing and settlement. 4. Provide hardware-agnostic CPMS supporting multiple charger manufacturers. 5. Automatically detect and resolve charger faults. 6. Meet EU regulatory and billing requirements. 7. Provide enterprise-grade reliability and scalability. Success metrics (KPIs) - ≥99.5% charger uptime - ≥98% vehicle readiness achieved - ≤5% manual intervention for charger faults - Energy cost reduction vs unmanaged charging ≥20% - System availability ≥99.9% --- 3.
