- The minimum unit capacity of the vast system reached 14.5 MWh, the highest globally to date, BYD said.
- Its blade batteries deliver a maximum capacity of 2,710 Ah, more than 300 percent higher than conventional energy storage batteries.
BYD (HKG: 1211, OTCMKTS: BYDDY) launched its next-generation energy storage system, Haohan, on September 18, intensifying its competition in the energy storage sector.
Haohan’s smallest unit capacity reaches 14.5 MWh, the highest globally to date, according to the company.
The energy storage system achieves an ultra-large capacity of 10 MWh within a space equivalent to a 20-foot container, BYD said.
By comparison, CATL (HKG: 3750) unveiled its Tener Stack on May 7, touting it as the world’s first mass-producible 9 MWh ultra-high-capacity energy storage solution. Tesla‘s (NASDAQ: TSLA) latest Megapack 3 has a unit capacity of 5 MWh.
Haohan employs dedicated blade batteries with a maximum capacity of 2,710 Ah, delivering over 300 percent higher capacity than conventional energy storage batteries, BYD said.
The system achieves a Vcts (Volume Ratio of Cell to System) of 52.1 percent, the world’s highest, BYD said.
Haohan elevates system integration to new heights with fewer enclosures, reduced footprint, and simplified management architecture, the company said.
The system features IP66-rated protection, doubling the lifespan of dust-sensitive components, reducing system failure rates by 70 percent, and cutting maintenance costs by 70 percent, it said.
Haohan provides robust support for the advent of terawatt-hour (TWh) scale power plants, accelerating grid upgrades, stated Cao Hu, director of BYD’s power science research institute for energy storage and new battery business.
BYD’s installed capacity of power and energy storage batteries reached about 23.175 GWh in August, marking a 22.97 percent year-on-year increase and a 3.69 percent rise from July, according to data released earlier this month.
From January to August, BYD’s cumulative installed capacity of power and energy storage batteries totaled around 180.051 GWh, reflecting a 66.84 percent year-on-year growth.
