Quality Management
Placing quality at the top, we leave no stone unturned when it comes to detail. With a focus on performance, our products serve as a testament to our unwavering commitment to quality management.
Our Quality Management System
Quality is an integral aspect of BLJ Solar’s corporate ethos. We strive to uphold the rigorous standards set forth by internationally recognized quality systems such as ISO 9001, ISO 14001, and OHSAS 18001.
By seamlessly integrating these standards into our core operations, we ensure a consistent commitment to quality. Furthermore, our relentless pursuit of continuous improvement drives our manufacturing processes to deliver exceptional quality at every step.
Tests throughout the Production
BLJ Solar employs a strict quality management system to conduct higher standards to guarantee that from product design to mass production. So our products can offer high efficiency, stable performance, and longer life.
Battery Test
Our Battery Pack Performance Test involves various tests to evaluate the charging and discharging functions, load voltage, and voltage balance, as well as overcharging and over-discharging protection of the batteries.
These tests assess the capacity, output voltage, cycle life, and other parameters to ensure compliance with quality standards.
Safety Test
Our rigorous battery safety testing ensures the highest standards of performance and reliability. Through comprehensive overcharging, over-discharging, and external short-circuit tests, we assess the battery’s ability to withstand extreme conditions and prevent risks such as thermal runaway or explosion, ensuring the utmost safety for our customers and their applications.
Reliability Test
Our battery reliability testing ensures the robustness and longevity of our products. Through specialized equipment such as aging cabinets, UV accelerated weathering testers, fully automatic plugging and unplugging test machines, and wear testing machines, we subject batteries to rigorous simulations of extreme conditions and long-term usage.
These tests evaluate parameters such as aging, outdoor weathering, connector performance, and wear resistance, guaranteeing the reliability and durability of our batteries in real-world applications.
Environmental adaptability test
Our rigorous environment adaptability testing ensures that our solar products can perform reliably in various conditions. With state-of-the-art equipment such as vibration testers, salt spray testers, rain testers, and double-layer constant temperature and humidity experimental boxes, we subject our products to simulated scenarios of vibration, corrosion, water impact, and extreme temperature and humidity.
These tests evaluate their resistance to environmental factors, guaranteeing their adaptability and durability in diverse real-world environments.
BMS test
Battery management system (BMS) tests include functions such as voltage monitoring, current control, temperature regulation, and cell balancing. We ensure the accuracy and reliability of BMS by conducting comprehensive tests, including voltage measurement accuracy, communication reliability, and fault detection. These tests ensure optimal performance and safety of our battery systems.
