What is a Battery Management System (BMS)?
Lead-acid batteries are low-cost and feature mature technology, but they are bulky, have low energy density, and contain lead and acid pollutants. Nickel-metal hydride (NiMH) batteries offer high safety and non-toxicity, but they suffer from high self-discharge rates and a mild memory effect. In contrast, lithium-ion batteries achieve lightweight and compact designs thanks to their exceptionally high energy density, alongside a long cycle life and extremely low self-discharge rate—operating smartly and efficiently when paired with an intelligent BMS.
From traditional lead-acid and NiMH batteries to lithium-ion batteries, the evolution of power technology has driven the intelligent and portable upgrading of countless end products. For B-side equipment, the battery is not an isolated component, but a core system that directly dictates the end product’s dimensional design, battery life, and power output.
High Energy Density of Lithium-ion Batteries
The most prominent physical characteristic of lithium-ion batteries is their high energy density. The gravimetric energy density of ternary lithium batteries can reach 200–300 Wh/kg, while that of lithium iron phosphate (LFP) batteries can also reach 160–200 Wh/kg. This means that under the same capacity requirement, the volume and weight of a lithium battery solution are only 1/3 to 1/4 of those of traditional batteries. Whether for portable medical devices, drones, or automated cleaning vehicles, high-energy-density lithium-ion batteries enable end products to achieve “smaller volume, lighter weight, and longer battery life.”
Long Cycle Life of Lithium-ion Batteries
The cycle life of lithium-ion batteries far outperforms that of traditional batteries. Under deep discharge conditions (100% depletion before recharging), it can reach 500–1,000 cycles. At 80% DOD (depth of discharge), the cycle life of ternary lithium batteries typically reaches 1,500–2,000 cycles, while LFP batteries can even exceed 3,500–6,000 cycles under standard operating conditions.
Extremely Low Self-Discharge Rate of Lithium-ion Batteries
The monthly self-discharge rate of NiMH batteries is as high as 15%–30%, whereas that of lithium-ion batteries is typically controlled within 1.5%–3%. For equipment requiring long standby times, a low self-discharge rate ensures that the device remains ready for use at any time even after long periods of inactivity.
No Memory Effect in Lithium-ion Batteries
Lithium-ion batteries have absolutely no memory effect and support charging at any time. In warehousing and logistics scenarios, AGV transport vehicles and forklifts do not need to shut down to swap batteries or be equipped with spare batteries, enabling continuous 24-hour equipment operation.
