FIELD: transport.
SUBSTANCE: invention relates to electric traction vehicles energy consumption monitoring. Device comprises bidirectional electric power meter and mobile communication unit. Meter is directly connected to high voltage line by voltage channel, and by current channel by means of measuring current shunt is to vehicle electric network. Meter includes measurement module, built-in nonvolatile memory and electric power meter processor. Measurement module is equipped with zero crossing detector. Built-in nonvolatile memory control input is connected to electric power meter processor, exchanging digital data with measuring module. Mobile communication unit includes built-in nonvolatile memory, connected to mobile communication unit processor. Mobile communication unit processor is connected to electric power meter processor and vehicle information network.
EFFECT: technical result consists in possibility to perform electric energy measurement and accumulation without changing connection circuit in DC and AC networks.
