When the Nigerian federal government removed the petrol subsidy in mid-2023, the cost structure of every Keke operator was rewritten. Electrification moved from optional to essential.
No inflated laboratory figures. Every TIANQIU pack has completed 12,000+ km of commercial field validation in the harshest parts of Lagos and Oshodi.

Almost every tricycle in West Africa charges from a small petrol generator after a grid outage — the “I pass my neighbor” unit — or from low-grade diesel generation. Output swings violently between 140V and 280V, and ordinary chargers and weak BMS boards are destroyed by the overvoltage pulses.
Active power factor correction (APFC) with active clamping suppresses the higher harmonics produced by generator sets and lightning-induced transients up to 1200V, so the vehicle leaves on a full pack every morning.
EMC: CISPR 25 Class 3 industrial certificationOn any overvoltage input or reverse transient pulse, the hardware protection loop hard-cuts within 8 milliseconds — without collateral damage to the vehicle’s cell group.
