Heat dissipation design of protective shell main content When the motorcycle starts the lithium battery at an instantaneous high rate discharge (more than 10C), the temperature of the battery core can soar more than 15 ° C in 30 seconds. If the heat dissipation is poor, it will lead to an increase of 20% in internal resistance, accelerate the capacity…
The structural design of the protective housing main content The motorcycle starting lithium battery needs to withstand up to 15G mechanical impact and IP67 waterproof and dustproof requirements under complex road conditions. The structural design of the protective shell directly determines the safety and reliability of the battery pack. the mechanical innovation of buffer design 1. Multilevel energy dissipation system…
Material selection for protective enclosures main content As a core component of the power system, the protective casing of the starting lithium battery of a motorcycle not only needs to withstand mechanical shock and vibration under complex road conditions, but also has to deal with environmental challenges such as extreme temperatures and corrosive media. The choice of shell material directly…
Shell and connecting parts main content The design of the casing and connecting parts of the starting lithium battery for motorcycles is one of the key factors to ensure the safe and reliable operation of the battery. The casing not only needs to protect the battery from the influence of the external environment, but also needs to have good heat…
BMS’s low-temperature preheating technology main content In an extremely cold environment of -30℃, the capacity of traditional lead-acid batteries can decline by up to 60%, while lithium batteries often face the predicament of cold start failure due to the sharp increase in the viscosity of the electrolyte (rising to 15 times that at room temperature at -20℃) and the sudden…
The equalization technology of BMS main content In the starting lithium battery system of motorcycles, the performance differences among individual battery cells can significantly shorten the lifespan of the battery pack and cause safety hazards. Studies show that when the voltage difference between battery cells exceeds 50mV, the effective capacity of the battery pack will be lost by more than…
