Constant power

 

 

Detailed pictures of climate controlled constant power test unit.

 

Cell output power &

discharge time are controlled per cell.

 

Battery output power is measured and adjusted at a rate of 10,000 times per second.

 

Cell voltages shown on computer screen are double checked  with a calibrated multi-meter.

 

Finally test data are processed through result calculation software (outcome in cycles, hr, mWh, stdev, etc.)

 

Hardware and software have been purpose-built in our own company.

 

Switching is done by solid state relays. One for each cell.

 

All mains are controlled and protected by an uninterruptible power supply.

 

All computers are connected to our LAN and backups are made on a daily bases.
