Battery Balancing Machine | High Precision Battery Test Equipment | WinAck

Product name

Battery Balancing Machine

Product model

WA-BTS-DB5V60A1CH300W

Product type

Dissipative type

AC input voltage (Customizable)

Single-phase 220VAC±10% / 50Hz

Power

350W

Input impedance

≥1MΩ

Current response time

Channel

No. of channels

1 Channel/Cabinet

Cabinets in parallel

By equipping the middle machine, multiple cabinets can be used in parallel.

Isolation performance

Each cabinet is isolated. Multiple cabinets can simultaneously charge and discharge multiple battery cells in the same battery pack without disconnecting the cell-to-cell connectors. In short, multiple battery balancing machines are combined into a battery cell balancer.

Control mode

Each cabinet is independently controlled.

Features

The constant-current source and constant-voltage source use a double closed-loop structure.
