Electric scooter components

E-scooter Electronics: Controller, BMS, Display, IoT

How the electronic part of an electric scooter works — everything that is invisible from the outside: motor controller (ESC) — six-step vs sine-wave/FOC, sensored vs sensorless, MOSFET; BMS (Battery Management System) — balancing, protection against thermal runaway, charging at sub-zero temperatures; UL 2271 / UL 2272 and New York's Local Law 39; IoT and telemetry in shared scooters (Lime Gen4, Bird Three, Spin S-200) vs Bluetooth-only in consumer models (Apollo, NAMI, Segway-Ninebot); display as a separate EY3/EY4 module over UART; why scooters still use UART rather than CAN.

Electric scooter frame, handlebar and folding mechanism: materials, fold types, known failures

How the structural components of an electric scooter are built: frame (6061-T6 / 7075 / 6082 aluminium, magnesium alloy, steel, carbon fibre), stem column, handlebar and grips (400–610 mm width, 22.2 mm grip diameter), folding mechanism types (lever-latch, multi-point hinge, twist-and-fold, push-button trigger-pin), known failure modes (Xiaomi M365 2019 recall, Lime/Okai sharing deck cracks, M365 stem-hook wear), and regulatory requirements (EN 17128:2020, ASTM F2641).

Electric scooter lighting and signalling: headlamps, taillights, turn signals, brake light, horn

How electric scooter lighting works: front white headlamp (from 300 to 2000 lm), red rear lamp and red rear reflector, side marking, turn signals (Apollo Phantom, NAMI Burn-E, Dualtron Storm), brake light — steady glow vs flash on deceleration, bell and horn (eKFV § 5 helltönende Glocke, EN 17128 audible warning device), regulatory minimums (eKFV § 5, UK rental trials, EN 17128:2020, ISO 6742-2, ISO 14878).
