The BYD Han EV 4WD is BYD’s flagship electric saloon model, BYD is China’s biggest electric vehicle manufacturer and the world’s second-biggest behind Tesla. The BYD Han EV 4WD is equipped with a 79.6 kWh battery and all-wheel drive dual-motors (163 kW front and 200 kW rear electric motors) that provide 487 cv. The BYD Han EV 4WD accelerates from 0-100 km/h in as little as 3.9 seconds and has a range of up to 550 km on a single charge. The BYD Han EV 4WD also has fast charging capability and takes only 30 minutes for a 80% charge.
The raw material, lithium iron phosphate has a number of beneficial characteristics: slow heat generation, low heat release and non oxygen release. The unique flat rectangle shape also improves cooling efficiency and preheating performance. Blade Battery has safely passed the nail penetration test without emitting fire or smoke.
The nail penetration test is regarded as one of the most rigorous ways to test the thermal runaway of batteries. The purpose is to simulate an internal short circuit of the battery. This is usually caused by external sharp metal objects penetrating the battery in a severe traffic accident. The Blade Battery passed the nail penetration test, without emitting smoke or fire. The surface temperature only reached 30 to 60°C.
Arranged in an array in one pack, each cell serves as a structural beam to help withstand the force. The aluminum honeycomb-like structure, with high-strength panels on upper and lower side of the pack, greatly enhances the rigidity in vertical direction. It is this revolutionary design that gives optimised strength to the Blade Battery.
An advanced energy-saving heat pump system comes as standard. Reliably operating in a broad range of temperatures, the system is designed to highly utilise residual heat from surroundings, the powertrain, passenger compartment and even the batteries. It enhances the thermal efficiency and reduces energy loss whether heating or cooling. Therefore, the low-temperature driving range is increased.
