The High Rate Discharge Tester (HEW) has been designed to perform high rate discharge on automotive batteries such as cold cranking tests in accordance with the programmed test schedule. Parameters are constant current, constant voltage, constant resistance and constant power.

For data evaluation, two powerful packages of Digatron/Firing Circuits well known battery testing software are available:
- Battery Manager for quality assurance and high volume testing and
- BTS-600 for research and development requirements.
BTS-600 allows to combine the HEW tester with Digatron / Firing Circuits Life Cycle Tester UBT and a Temperature Chamber to establish an automated IEC teststand.

Numerous options are available such as paralleling multiple cabinets, single cell operation, cell/battery drop out, multi range switching, temperature inputs, data-logger interface, CAN-Bus interface as well as digital inputs and outputs and a RS 232 interface to the climatic chamber.

Standardized discharge schedules (EN, DIN, SAE, IEC,JS etc.) such as cold cranking tests and/or userdefined test schedules for automotive batteries and all other types of batteries.
The modular power module design, the combination of a variety of options and the flexible program editor allow to set up an automated IEC test stand effecting long term cycle life and cold cranking tests without any manual battery handling.
