A detection method for a drive (1) is provided. Firstly, a step (S1) is performed to determine whether an operating parameter of the drive (1) is normal. If the determining condition of the step (S1) is satisfied, a step (S2) is performed to determine whether a value of the abnormal flag is 1. If…
A battery management unit that manages an energy storage cell, the battery management unit including: a current sensor that measures a charge/discharge current in the energy storage cell; a first communication unit that communicates with a vehicle; and a management unit, in which the management…
A control apparatus an the electric vehicle acquires a detection value of an output current of a battery to be detected by a first sensor, and a detection value of a drive torque to be transmitted to a wheel and to be detected by a second sensor, calculates an actual torque-current characteristic…
Control systems and methods for an electrified powertrain of an electrified vehicle include performing, by a main control system, a sequence of first processes based on an initial input including a set of signals indicative of at least one of a driver torque request and expected vehicle behavior…
An electrical system for providing electrical power to an electric machine, where the electrical system includes a single point disconnect switch for multiple battery systems. The single point disconnect switch may be remotely mounted. In some examples, operation of the disconnect switch…
Provided is an electronic control unit mounted on an electrically driven vehicle, the electronic control unit being excellent in reliability and convenience in which recovery is easy while reliably shutting off a high-voltage power supply line at the time of collision of the vehicle or failure of a…
An electrified vehicle includes a contactor having a coil operable by a low-voltage control signal to selectively electrically couple a terminal of a high-voltage bus to a charger receiving power from an external source. A programmed controller predicts the time it will take for the contactor to…
A relay control apparatus for a relay including a contact connected between a positive electrode of a battery and a load, and a coil connected between a relay power terminal and a ground in which the contact moves to a closed position when the coil is energized. The relay control apparatus includes…
Each of a plurality of monitoring units (10) that monitor the states of batteries allocates, as identifying information for itself, identifying information corresponding to an input signal inputted from a preceding control unit (3) or monitoring unit (10); outputs, to a subsequent monitoring unit…
A control system includes an electrical power source and an alternating current (AC) power supply electrically coupled with the electrical power source. An uninterruptable power supply is electrically coupled with the AC power supply for storing and returning electrical energy supplied by the AC…
In a drive system using a single synchronous motor which is not paired with a synchronous generator, even if a failure occurs in an analog angle data converter for detecting the rotation angle of the synchronous motor, the driving of the synchronous motor can be continued in a temporal emergency…
A control system to control an electric drive, the control system comprising: a main controller operable to execute instructions including the computation of a value based on at least one parameter; and a monitoring module operable to provide queries from time-to-time to the main controller…
