How BYD Blade Battery Advances EV Performance

Battery Pioneers

BYD has been manufacturing batteries for more than 29 years. From 1995 to 2005, the company focused solely on battery manufacturing.

The automobile sector was launched later that year, and battery-powered cars were introduced in 2008. We can call BYD battery pioneers, considering their years of experience.

EVs

The Blade Battery was explicitly designed to power BYD’s EV lineup. The all-electric vehicles were launched in 2021 as part of the company’s plan to go global.

Every model in BYD’s EV lineup has the same ‘Blade Battery.’ This move reflects the company’s confidence in the battery they’ve designed and incorporated throughout the lineup.

Claims

BYD’s Blade Battery is the safest battery on the market. The battery has passed extensive tests and is claimed to be the safest. Let’s wait for customer reviews aside from company claims.

It offers the highest strength, maximum range, and many life cycles. The cells installed are engineered to be the highest quality available.

Material Used

BYD uses Lithium Iron Phosphate (LiFePO4) as the raw material for their batteries. This material has several supporting characteristics that help build a battery up to standard.

LiFePO4 has slow heat generation, low heat release, and doesn’t release oxygen. The battery is flat rectangular, supporting cooling efficiency and preheating performance.

Nail Penetrating Test

There is a test called the nail penetration test, in which a foreign object is forcibly inserted into the battery. This test is performed to observe how the battery reacts when penetrated.

The nail penetration test is the most rigorous way to test the thermal stability of a battery. This test simulates an internal short circuit and severe traffic accidents.

Nail Test Outcomes

This test helps identify potential dangers in conditions like accidents. The Blade Battery has safely passed the test without emitting fire or smoke.

The Blade Battery’s temperature was monitored during the test. The surface temperature only reached 30-60 degrees Celsius, which is considered relatively safe.

Honeycomb

The Blade Battery is packed uniquely. It is designed with an aluminum honeycomb-like structure, providing extreme strength in an upright position.

Each cell acts as a separate beam in this honeycomb structure to provide structural rigidity to the battery. The cells are arranged vertically to withstand extreme pressure and challenging conditions.

Rigid Plates

The aluminum honeycomb-like structure in a vertical arrangement is further protected. A high-strength panel covers the upper and lower sides to ensure maximum safety.

The plates and the vertical structure inside create a sturdy, sandwich-like design. It’s a smart way to pack a battery, offering a revolutionary design and optimal strength.

Space utilization

BYD claims that the Blade Battery is packed smartly and compactly. Compared to traditional battery packs, it takes up only half the space for the same strength.

This way, 50 percent of the space is saved with this tight arrangement. It provides enhanced energy density, a more extended range, and adds structural strength.

5000 Cycles

The Blade Battery offers a longer battery life with several charge cycles. It is claimed to have over 5,000 charge and discharge cycles.

BYD provides a warranty for their battery for 6-8 years or 160,000 km, whichever comes first. The warranty is voided once either condition is met. Let’s see how well it performs.

Cobalt-free

Cobalt is an element that is feared to pollute the environment through electrical waste. Cobalt pollution has become a significant concern with every gadget and machine powered by a battery.

The material used in the blade battery is lithium iron phosphate (LFP), the cathode material. This provides higher levels of safety and proves to be more thermally stable. It is cobalt-free, unlike conventional lithium-ion batteries.

Temperature Tests

The Blade Battery also underwent several additional tests before being successfully launched. It was heated in an oven to over 300 degrees Celsius to check its stability.

Furthermore, the battery was bent, crushed, and overloaded to 260 percent of what it could withstand. All of the results came out in favor of the Blade Battery.

Cell to Pack Arrangement

The Blade Battery is equipped with cell-to-body technology, seamlessly integrating the Blade Battery into the car body, creating a layered structural design.

With this technology, the Blade Battery is much more than just a power source for the vehicle. It adds structural rigidity, allowing the car to withstand high forces, making it safer, and contributing to its 5-star safety rating.

Extended Range

The clever arrangement of the battery saves 50 percent of space. The more space available, the more batteries can be placed in the area.

More batteries mean a more excellent travel range for EVs. More batteries also provide more structural strength to the chassis. All of this plays a vital role in BYD’s increased sales.

Structural Strength

The cell-to-pack arrangement means the ultra-thin battery pack is embedded directly into the car’s body surface. This arrangement offers several benefits.

The battery pack lowers the car’s center of gravity, providing extra grip on the road. It also enhances the car’s structural strength.

Future of BYD Batteries

BYD launched the Blade Battery in March 2020. This means they innovated the battery before launching a new range of EVs.

The company is so confident in its innovation that it features it in every car. Every EV is equipped with the Blade Battery, and that’s certainly a big deal. The success of the Blade Battery is tied to the success of the entire EV range. The whole production line is at stake if things don’t go as planned.
