Battery tests are conducted over seven dimensions of safety, covering internal and external short circuits, overcharging, collisions, high voltage, connections, and harmful gases. The safety assessment is performed from five perspectives: electrical safety, mechanical safety, thermal safety, environmental reliability, and gas flammability. A comprehensive safety system for power batteries is built across four levels: cell, module, battery pack, and system. Based on complex working conditions and the full life cycle, our safety testing goes above and beyond the current national standard requirements.
The battery pack is designed to resist catching fire or exploding under compression and has passed tests simulating collision and compressive strength.
Vehicles equipped with blade batteries, such as the BYD Seal, can easily achieve a range of 700km.
With an efficient wide-temperature-range heat pump system and direct battery cooling and heating technology, the battery pack can quickly raise its operational temperature in low temperatures, meeting the driving demands under cold conditions.
The charging power can reach 230kW or above.
The battery can be charged and discharge for more than 5000 times, and the range converted based on the cycle life far exceeds the service life of the vehicle.
For the development of new energy vehicles, the key consideration has shifted from merely increasing driving range to enhancing safety and intelligence. In this context, the significant cost advantage of lithium iron phosphate is brought to the forefront. Through continuous cost reduction, the cost of parts has been reduced by 45%, and the overall cost by more than 30%.
