The North American Electric Reliability Council (NERC) highlighted multiple risks such as supply chain disruptions, surging demand, and inadequate grid modernization in an evaluation of the long-term stability of the U.S. Grid at the end of 2023. Beyond the U.S. market, the escalating frequency of extreme weather globally has heightened the risk of widespread power outages, prompting many households to consider to purchase home energy storage systems to ensure power supply during outages.

At the 2024 RE+ (Solar Power International) in the U.S., CHAM New Energy unveiled its groundbreaking first-generation Open Dao integrated machine，and the upgraded version of stackable high-voltage household storage system Force X1. These new products are safety and efficiency-prioritized, catering to diverse household power needs while incorporating eco-friendly design principles, thus contributing to a carbon-neutral future.

A Versatile Provider of Intelligent and Efficient Storage Solutions

On September 10, over a hundred guests from home and abroad, media agencies, and attendees collectively witnessed the debut of CHAM New Energy's latest innovations at the Anaheim Convention Center in California - the first-generation Open Dao integrated machine, and the stackable high-voltage household storage system Force X1, as well as its 32 series large cylindrical battery, 46 series large cylindrical battery, a range of household balcony solar station solutions, residential storage solutions, and new outdoor power equipment.

Presently, the energy storage industry is challenged by product safety and product cost-effectiveness:

• Safety concerns: Safety is a paramount concern for users of energy storage products. Along with the rapid expansion of the energy storage industry in recent years, an influx of new companies have entered the market, each with their unique production techniques. Behind the industry's rapid growth, however, lies the uneven quality of products, as well as the rampant issues of substandard quality and price-driven competition, posing potential hazards to industry safety.

• Cost-effectiveness concerns: While safety is the "weak link" in the figurative "barrel effect", factors such as product lifespan, operational costs, and adaptability to diverse applications are the "strengths" that equally impact the overall product experience. Currently, it is urgent to develop a comprehensive set of solutions through technological innovations to tackle these challenges in the industry.

By accurately identifying the industry trends and learning user requirements, CHAM New Energy has rolled out two products to solve the foregoing industry pain points:

The first-generation Open Dao integrated machine is tailored for emergency power supply for households and small to medium-sized businesses, and can also serve an energy reservoir for electric vehicle charging stations. It can ease peak-hour electricity demands. Engineered with AC, DC, and distribution modules, the product features great flexibility and ease installation. Its configurations can be tailored to specific requirements. A single unit can house 5 to 10 10kWh battery packs in various arrangements. Furthermore, it supports off-grid and parallel multi-unit usage, providing users with worry-free options from 50kWh to 1,000kWh.

In its design, the original battery pack structure of CHAM New Energy's first-generation Open Dao integrated machine integrates the functions of heat management, heat isolation, and insulation. This design ensures the high efficiency, safety, and long service life of the product. Through the application of the MES production management system in the production of Open Dao, the transportation efficiency is enhanced using AGV, welding quality improved using the closed-loop control system of an imported circular seam welder, and product reliability increased using the online AI detection technology.

According to information, this energy storage system is supported by the AI intelligent temperature control technology in conjunction with advanced structural design, resulting in a temperature differential of less than 2°C within the battery pack. The system features a cycle life exceeding 6,000 cycles and an operational lifespan of over 10 years, far outperforming industry-standard competitors in the market. The overall system design complies with industry standard requirements such as UL9540A and NFPA855.

The other upgraded new product of CHAM New Energy, stackable high-voltage household storage system Force X1 is tailored for households. Through its modular design, it offers flexible energy configurations to meet varying household power requirements. As a residential energy storage solution, it features the 32140 large cylindrical lithium iron phosphate cells with patented ultra-low internal resistance technology. The entire battery cluster can be quickly installed by a single person in just 10 minutes. In strict compliance with the standards of the PX5 waterproof level, IP6X dustproof level, C4 anti-corrosion level, and Level III UV resistance, shock resistance, electric shock protection, and cold resistance, it is perfectly adaptable to diverse environments.

Imagine a scenario where a severe natural disaster such as a typhoon or earthquake hits, making the regular power grid fail. In such a situation, the robust Force X1 serves as an emergency power source, ensuring basic electricity needs. Psychologically, its users can feel quite assured.

According to the Insights from EPRI's Battery Energy Storage Systems (BESS) Failure Incident Database released by the EPRI in 2024, approximately 65% of incidents may arise from the operation and integration of battery systems. Force X1 users can opt to configure 2 to 5 battery packs, creating a single cluster with a storage capacity ranging from 9.2 to 23.0kWh. By connecting up to 5 clusters in parallel, a high-capacity 115kWh energy storage system can be established to cater to a wide range of commercial and industrial applications such as communication base stations, street lighting systems, clubs, small sports arenas, and farms. The system's clusters can be automatically networked using communication cables and accessories, eliminating the need for dip switch settings or other operations. Moreover, the failure of any single cluster will not disrupt the operation of the remaining clusters, significantly enhancing the overall system reliability.

In addition, following a user-centric approach, the team of CHAM New Energy designed an intelligent BMS for Force X1. This BMS employs algorithms based on multi-dimensional data including voltage, rates, temperature, internal resistance variations, and idle duration. Moreover, it compares, and corrects in real time the massive stored data uploaded to the cloud, ensuring the precision of SOC calculations within ±3%. In this way, the safe and efficient operation of batteries is guaranteed.
