Electric Bicycle Batteries: Emphasizing Both Technology and Safety
Blog Article
The battery is the core component of an electric bicycleElectric bike . Its performance and safety directly affect the vehicle's usability and the rider's life safety. Currently, common batteries for electric bicycles include lead - acid batteries, gel batteries, nickel - metal hydride batteries, and lithium - ion batteries.
Lead - acid batteries are the most common type of electric bicycle batteries. They have advantages such as low cost and mature technology. However, they also have drawbacks like being heavy, having a short range, and a short lifespan. Gel batteries are an improvement over lead - acid batteries. They use a gel - like electrolyte, which can avoid thermal runaway and extend the battery's lifespan. Nickel - metal hydride batteries have a high energy density, high power density, and good low - temperature discharge performance, but they are relatively expensive. Lithium - ion batteries have the advantages of high energy density, high power density, and low self - discharge750w electric folding bike , and are widely used at present.
However, the safety of batteries cannot be ignored. Illegal modification of batteries, such as replacing them with high - capacity batteries or using inferior chargers, may cause short - circuits or thermal runaway during charging and use, leading to fires. To ensure battery safety, relevant departments have introduced a series of standards and regulations, such as GB 43854 - 2024 “Safety Technical Specifications for Lithium - Ion Batteries for Electric Bicycles.” When purchasing electric bicycles and batteries, consumers should choose products from regular channels, charge them correctly according to the instructions, and regularly check the battery's condition to ensure safe use.
