Heavy-Responsibility Trucking with Progressive Battery Expertise – Merchandise

With expertise fueled by innovation, BYD heavy-duty electrical automobiles are purpose-built and exhausting at work exemplifying the endurance and reliability of its iron-phosphate batteries. Uniquely positioned because the trade’s solely environmentally-friendly battery chemistry, BYD hopes to encourage the mass-market adoption of inexperienced expertise to realize its environmental objective of cooling the earth by 1°C.

Battery Security

BYD Iron-Phosphate Batteries are designed and manufactured to supply secure, constant, and dependable power throughout rigorous and demanding purposes. With security as a precedence and a core power of its merchandise, BYD internally developed the Fe Battery chemistry to make sure the steadiness of every of its electrical automobiles. With hundreds of thousands of on-road miles and over 25 years of R&D and manufacturing expertise, BYD batteries are constructed to final.

BYD’s revolutionary Iron-Phosphate Batteries are utterly non-toxic with no thermal runaway occasions, even in probably the most excessive circumstances. BYD confirms electrode buildings in line with many experiential fashions, equivalent to present distribution fashions, thermal fashions, electrochemical fashions and mechanics fashions, to scale back resistance and optimize the present distribution and thermal distribution within the cell. Good thermal efficiency for high-power cells requires substantial thermal conduction paths, and may make sure the long-term stability and security of a cell. BYD makes use of thermal imaging to substantiate best-in-class thermal balancing inside a cell.

A number of checks have been carried out to the BYD battery modules and packs to make sure security. A few of these embrace: Vibration/Shaker Desk Testing, Thermal Shock Take a look at, Salt Spray Take a look at, Crush Testing, Quick Circuit Testing, Collision Take a look at, Quick Present Take a look at, One-Hour Hearth Simulation Take a look at, and Fuel Flaming Take a look at.

Battery Design

BYD developed its Fe Battery Chemistry to be freed from heavy metals and poisonous electrolytes whereas possessing the smallest environmental influence of any electrical car battery system out there at present. The batteries are multi-purpose, initially powering battery-electric automobiles after which used on power storage techniques. BYD’s battery electrical vans make the most of the identical environmentally pleasant Fe Battery expertise that’s equipped inside its giant scale fastened Power Storage Stations (ESS).

The batteries don’t include any poisonous electrolytes or heavy metals in both the cathode or the anode. They aren’t manufactured with any caustic or dangerous supplies, ensuing on this planet’s first environmentally-friendly, high-energy density, and rechargeable chemistry. BYD’s Fe Battery cathode is the most secure cathode materials as a result of there isn’t any thermal run-away mechanism or oxygen generated when decomposing. It is also probably the most sturdy when cycled as a result of there isn’t any net-net quantity acquire inflicting untimely cell swelling or impedance progress. The Fe Battery packs not solely meet the entire U.S. rules, but in addition surpass the stringent U.S. DOT and FMVSS car requirements.

BYD battery packs use probably the most dependable welding strategies obtainable for assembling battery cells inside a module. BYD makes use of each laser and ultrasonic welding to make sure that every battery meeting just isn’t solely dependable but in addition gives probably the most environment friendly thermal distribution.

Battery Cycle Life

When BYD produces its Fe Battery, the Whole Life Cycle of every cell is at all times thought-about. In contrast to different electrical truck producers that present a single use of their batteries, BYD is in a singular place, due to its vertical integration, to repurpose the batteries and put them into their very own Power Storage Methods as soon as they attain their helpful life cycle.

BYD has repeatedly cycled its very giant particular person modules (a number of cells in every) for a few years. Entire car packs (with a number of modules) have been examined underneath steady load, elevating the floor temperature of the modules to about 40C. Nonetheless, even underneath these harsh circumstances, the capability has remained at over 85% after 2,000 cycles, and over 75% after 4,000 cycles. After 9,500 cycles, the battery capability stays at over 70.7% and the degradation curve is way more steady than any competitor’s modules.

This knowledge was collected on a collection of many modules all performing equally – 6 cycles of charging and discharging have been accomplished day by day and this 9,500-cycle check has at present taken 5 years to get the information proven under. BYD have proven that these obtain properly over 10,000 cycles, and the cell capacities can nonetheless attain 70% of the preliminary capability. 10,000 single cell cycle testing contains six cycles every day.
