About us


Established in 2005, Fujian Nebula Electronics Co. ltd (Nebula, for short) headquarters in Fuzhou city, Fujian Province, China. Nebula is a high-tech company providing all kinds of battery test equipment & solutions, including battery PCM/BMS tester, Cycle tester, battery working condition simulation tester, battery intelligent manufacturing solutions. For now, Nebula has offices in Shenzhen, Suzhou, Tianjin, Chongqing to serve our customers.
Product portfolio covers Li-ion battery pack PCM tester, Li-ion battery pack semi-product/ end product tester, Li-ion battery pack cycle tester, Power battery pack BMS tester, Power battery pack EOL tester, Power battery pack working condition simulator, ES inverter, Wind-Solar- Charging-ESS control system, automatic cell sorting machine, automatic cell welding machine, Li-ion battery intelligent manufacture solution and MES, etc. So far, the products apply to 3C/e-tool & e-bike/EV &ESS. Our products have been’ accepted by lots of Li-ion battery manufacturers and EV corporates. For example: BYD/GUOXUAN HI-TECH/HUAWEI/CATARC(China automotive technology & research center)/MICROVAST/LISHEN(Tianjin)/ATBS/BAK/Nanjing Golden Dragon Bus Co. Ltd/MENSHINE(Fujian)/SCUD, etc.
There are 7 R&D departments which will update the current products or develop new products according to market in order to solve the problem our customer come across.

System integrator of Li-ion battery pack automatic assembly line and professional supplier of battery working condition simulation test system

Nebula has a powerful R&D team. Not only could we provide Li-ion battery test equipment, automatic equipment or MES, but also could we customize a 3 in 1 solution. What Nebula want to do is to help customer guarantee the quality while increase the capacity.
Quality comes first: Nebula’s solution base on our testers and MES, our clients could track the test results and control the quality during the manufacturing process. With the high accuracy, fast response features, our solutions are capable to push our clients find out the problems and improve them. For example, Li-ion battery pack EOL tester is a system that can provide one-stop test solution for battery pack’s assembly, such as insulation & voltage withstand/BMS and safety performance. All the tests mean to make sure the products are safe.

Increase capacity: No matter cell sorting machine, cell welding machine, Plasma cleaning machine, Polarity distinguish machine, or the battery pack intelligent manufacturing solution, all the products are designed for capacity increase, less manual intervention, cost-cut down.
Nebula power battery working condition simulation test system is a high power cycle tester. The index including current rise time, switching time and output accuracy are all advanced level in the global. It could simulate the EV battery’s actual working output in lab. This system is applied to the labs & plants of many battery manufacturers, EV corporate and the third-party test institutions. Nebula has developed the newest series(NO.3) power battery pack working condition simulation test system with the innovation spirit and acute market insight. Therefore, Nebula becomes the leader of this industry.
In recent years, Nebula applies the AC/DC mixed grid technique of battery working condition test system to the ESS successfully and developed multiple excellent AC/DC and DC/DC bidirectional inverters.
With the spirit of technology push the development and innovation lead the future, Nebula has become professional system integrator of Li-ion battery pack automatic assembly line and supplier of battery working condition simulation test system.
