Easy and safe use of Li-ion batteries in test stands.

• Foam glass granulate filling (pyrobubbles) as extinguishing agent in case of bursting or fire (with extinguishing agent certificate)
• Certified container according to UN3480, packaging class II with ADR approval
• Cooling system for thermal conditioning of the battery (dissipation of power loss)
• Electronic safety monitoring of battery and container with early warning indication
• Acquisition of measurement data (voltage, current and temperature) and output via CAN-BUS
• Robust steel tank with pressure compensation valves
• EMERGENCY STOP circuit including button and interlock input for connection to the test bench
• Automatic shutdown in the event of critical battery errors, e.g. via a safety cut-off relay

Both conventional lead accumulators and Li-ion batteries can be operated.

Depending on the equipment variant, current fuses and reverse polarity protection as well as diagnostic elements such as temperature monitoring and CAN communication for battery management are possible.

The CAN Controlled Power Unit acts as a power, logic and measurement interface between control and power electronics in test bench structures (especially engine test benches).
Basic features:

• Separation of control and power electronics
• CAN bus interfaces
• The use of ProFETs in the power section enables low losses and a long service life.

Extensive connection options

• Operating voltage between 5V and 30V.
• 5 power outputs up to 70A
• 2 half bridges 15A, PWM-capable up to 1kHz
• 1 full bridge 7.5A
• 14 digital inputs, 4 digital outputs
• 4 analog inputs, 4 analog outputs
• 5 separate CAN nodes with switchable terminating resistors
• Powerful CPU

Enables complex sequence controls, simulations and gateway functions, which we can implement upon customer request.
