HOPPECKE Battery Control Unit (BKE-01)
Technical information for BKE-01Summary
The BKE01 is an intelligent precision direct current meter which is used to monitor the state of charge of nickel-cadmium
batteries. An ultra-precision bipolar integrator detects the measuring voltage at a shunt resistance, and from this generates a pulse train proportional to the current. This pulse train is evaluated by a microcontroller and shown on a display in bar format by means of 11 LEDs. The display corresponds to the state of charge of the
battery expressed as a percentage. Electrical specifications
Operating voltage:18 … 120VDCPower consumption:
3 relays, switching state is maintained even if operating voltage fails, 1 switch contact in each case. Break or make contact function may be set during parameterisation.Contact rating:max. 100 Vmax. 0,5 Amax. 10 WThe above values relate to a “resistive” load; inductive loads must be wired-up to an external spark quencher. Suitable for all kinds of vehicle Current measurement
Measuring range: ±0,15 … 150mVLoad: > 1,5 kOhmMeasuring error: ±0,6 … 60mV, < 0,8%±0,15 … 150mV, < 1,5%Temperature error: ±0,05%/KThe shunt resistance may be installed at the negative terminal, the positive terminal or at any position in between.
