Yokogawa targets data logging in high voltage electric vehicles

Yokogawa Electric has developed a high-voltage analogue input module for data collection in the development and production of electric vehicles (EVs) and plug-in hybrid vehicles (PHVs).

The GX90XA-10-V1 module provides measurement of multiple channels under high-voltage conditions as part of its OpreX data acquisition range.

For the development and production of EVs and PHVs, and on-board vehicle batteries, performance evaluation tests involving the measurement of voltage levels in multiple battery cells must be performed. The batteries used in such vehicles can have hundreds of interconnected cells, and the voltage levels at all these points must be measured simultaneously.

The test devices that are used must be capable of withstanding voltages of several hundred volts (high common mode voltage) that are typically applied between the measuring terminal and the ground.

The high-voltage analogue input module allows the measurement of multiple channels under high-voltage conditions.

The GX90XA-10-V1 has two layers of insulation and can withstand a common mode voltage of up to 600V ACrms or 600V DC, and is capable of sampling data at intervals as short as 100ms.

With the GX and GP series recorders, the module can accept up to 450 inputs; with the GM10 data loggers it can accept up to 420. 

When the GX90XA-10-V1 module is mounted on a GX or GP series recorder or on a GM10 data logger, voltage measurement data can be monitored from a host system, and the collected data can be uploaded to a database for sharing.
