ELP400 EV Solutions


Intelligent Digital Power Supply

ELP400 has built-in various test and maintenance modes, which are suitable for the discharge, charging, cycle charging and discharging tests of various lithium batteries on the market. Adopting an intelligent operating system and supports wireless data transmission, it helps to maintain and manage the battery pack, thus extending its service life.


  1. The 7-inch LCD touch screen and the intuitive menu simplified the operation.

  2. Portable, easy to carry and transport.

  3. Applied to all common lithium battery packs testing with various voltage levels. 

  4. Equalizing maintenance test can activate the lithium battery performance completely.

  5. Support intelligent equalizing function, and equalizing maintenance parameter customization.

  6. Adopt wave width modulation technology, high efficiency, high power factor, low noise, low electromagnetic interference.

  7. Support multiple protection design and alarm settings of voltage, current, temperature abnormal to protect the battery and the balancer.

  8. Support the safety protection functions such as overvoltage, undervoltage, overcurrent, output short circuit, anti-reverse protection and overheating protection.

  9. Multiple discharge auto-stop conditions make testing mode more intelligent and flexible, and avoid over-charge and over-discharge. 

  10. Customized setting the total charging time, constant voltage time, charging capacity, and charging current.
