A. Challenges & Pains
1. Lead-acid batteries have low start rate, serious capacity attenuation (＞60%) in -20℃ low temperature, and cold start jamming of large-displacement models;
2. Large battery volume/weight, long custom mold cycle (≥45 days) for multiple models, affecting mass production;
3. Low protection grade, high short-circuit failure rate in rainy days, and high after-sales repair rate.
Correlation：High-rate discharge, extreme environment adaptation, customized matching
B. Solutions
Customized product: 72V 34Ah high-rate sodium battery motorcycle starter battery for 3 mainstream models.
1. 150-person R&D team optimized BMS temperature control algorithm, 30C normal temperature start rate, 17C discharge rate at -20℃;
2. Humanized Design: 60% weight reduction vs lead-acid, modular interface adaptation without modifying vehicle structure, IP67 waterproof and anti-short circuit;
3. Reserved fast charging interface, matching the customer's existing charging equipment, custom cycle shortened to 15 days.
C. Final Results
1. Performance: 100% low-temperature start success rate, capacity attenuation ≤10%, rainy day failure rate reduced by 95%;
2. Delivery: 5000 sets of first order delivered 3 days in advance, flexible replenishment for bulk orders;
3. After-sales: 24h initial feedback, 48h on-site maintenance plan, 80% improvement in response efficiency.
