BYD Blade Battery Redefines EV Safety With Nail Penetration Test

Cimex Inc. Pvt. Ltd., the authorized distributor of BYD Auto Industry Co. Ltd. in Nepal has conducted the demonstration of BYD Blade Battery to highlight the EV safety standards. The test was conducted in Greater Noida, India in the presence of visiting delegates from Nepal.

The event was jointly hosted by Cimex Inc. & BYD India Pvt. Ltd. The nail penetration test is also considered the 'Mount Everest' of battery tests as it is the most rigorous way to test the thermal runaway of batteries. BYD’s patented technology Blade Battery is the only battery to successfully pass the Nail Penetration Test.

The Blade Battery has been developed by BYD over the past several years. The singular cells are arranged together in an array and then inserted into a battery pack. Due to its optimized battery pack structure, the space utilization of the battery pack is increased by over 50% compared to conventional lithium iron phosphate block batteries. The Blade Battery has also passed other extreme test conditions, such as being crushed, bent, heated in a furnace to 300°C and overcharged by 260%. None of these resulted in a fire or explosion.The Nail Penetration Test: 

Blade Battery

While undergoing nail penetration tests, Blade Battery neither emitted smoke nor fire after being penetrated, and its surface temperature only reaches 30 to 60° C.

NCM Battery

Under the same conditions, a ternary lithium battery mostly exceeds 500° C and violently burns, with the surface temperature reaching dangerous temperatures of 200 to 400° C.

Addressing the visiting delegation from Nepal, Shrirang Joshi, National Sales Head - Passenger Vehicle Business, BYD India, shared BYD's proven and innovative technology. "EV manufacturers in recent years have been competing for greater cruising range. This leads to an unrealistic focus on "higher energy density" in the battery industry and a neglect of safety. BYD’s Blade Battery aims to bring battery safety back to the forefront, a redirection from the industry’s tenuous focus on this crucial aspect." added Mr TVC Rao, National After-Sales Head, Passenger Vehicle Business, BYD India Pvt. Ltd.
