As the global demand for lithium batteries continues to surge, manufacturing plants are facing increasing challenges related to power quality. High-frequency switching loads such as rotary kilns, induction heating, and other nonlinear equipment often generate excessive harmonic distortion and poor power factor—threatening the stability and efficiency of factory operations.
The Challenge
At a major lithium battery production facility in Tongling, Anhui, China, complex site conditions and fluctuating loads led to serious power quality problems. The main issues included:
- Severe harmonic distortion, particularly even-order harmonics
- Low power factor
- Continuous malfunctioning and protection trips of capacitor banks due to harmonic overload
These issues not only impacted the plant’s operational efficiency but also posed risks to electrical equipment and increased energy costs.
The Solution: Enjoypowers APF Deployment
To address these challenges, Enjoypowers deployed 48 units of APF-150A active power filters across the facility. These APF systems are designed to dynamically filter out harmful harmonics and improve power factor in real time.

Why Power Quality Matters
In industries with sensitive and energy-intensive equipment, poor power quality can lead to:
- Equipment overheating and premature failure
- Higher energy bills due to penalties or inefficiency
- Production downtime and safety risks
By installing active harmonic filters (APFs), facilities can maintain grid compliance, optimize energy use, and ensure uninterrupted operations.
