It can be fully charged in 8-10 hours with a household charging pile, and 80% charged in 30 minutes with a public fast charging pile, meeting users' energy supplement needs in home, outdoor, long-distance and other scenarios. In addition, the battery adopts ultra-fast charging long-life negative electrode technology, combined with high-temperature resistant SEI film reconstruction technology, which effectively solves the damage to battery life caused by ultra-large current charging, achieving both fast charging and long service life, allowing users to enjoy the convenience of ultra-fast energy supplement without worrying about excessive battery loss.

　　All-dimensional safety protection, building a solid travel defense line, and guarding the safety of people and vehicles. The safety of electric vehicle batteries is directly related to the travel safety of users and is also the core focus of the industry. This rechargeable lithium-ion battery adopts a high-strength sealed shell design, combined with a honeycomb aluminum plate protection structure, which increases the puncture resistance by 300%, effectively resisting external impacts such as collision, extrusion and puncture, and preventing cell damage. It has a built-in intelligent BMS battery management system that real-time and accurately monitors core parameters such as battery voltage, current, temperature, power, and cell balance, and is equipped with eight core protection functions: overcharge, over-discharge, short circuit, over-temperature, over-current, under-voltage, anti-reverse connection, and thermal runaway. When an abnormal situation is detected, it will immediately cut off the circuit automatically to prevent potential safety hazards such as battery bulging, leakage, and explosion, and send an alarm signal to remind the user to deal with it in time. In addition, the battery has excellent wide temperature adaptability, adopting aerospace-grade thermal insulation technology and low-temperature superconducting electrolyte technology, which can stably charge and discharge in extreme environments of -40℃ to 60℃, with a low-temperature energy retention rate of more than 90% at -20℃. It can start normally and drive stably even in extremely cold weather, avoiding problems such as range shrinkage and charging failure caused by too low temperature, and adapting to various climate scenarios such as severe cold in the north and extreme heat in the south.

　　Durable, long cycle life, reducing use cost. As a core component of electric vehicles, the replacement cost of batteries is relatively high, and their service life directly affects the long-term use cost of users. This rechargeable lithium-ion battery has passed strict charge-discharge cycle testing, with a cycle life of more than 3000-4000 times and a service life of 10-15 years. Calculated by an average of 200 charges per year, it can meet the user's needs for more than 15 years, which is 2-3 times that of traditional rechargeable batteries, greatly reducing the frequency of battery replacement and long-term use cost. At the same time, the battery adopts high-stability cells and optimized charge-discharge management technology, which can still maintain stable performance output even in complex use scenarios such as high-frequency charge-discharge and long-term idleness, avoiding problems such as sudden capacity drop and performance attenuation. In addition, the battery supports modular replacement of cells. If a local cell fails, there is no need to replace the entire package, only the faulty cell needs to be replaced, which further reduces maintenance costs, improves economic efficiency, and makes battery upgrades for old electric vehicles more convenient.
