摘要： The invention relates to a method for estimating the torque of an electric machine (4) of a hybrid or electric drive motor vehicle, wherein the power currents (l
d , I

F ) of the electric machine (4) expressed in a two-phase reference frame are determined, the components (
φ
d ,
φ
q ) in the two-phase reference frame of the magnetic flux (φ) induced by the electric machine (4) are estimated, and an estimation (C

摘要： The invention relates to a method for detecting defects in an electrical power storage system comprising at least one battery. The method comprises a step for applying an instruction for charging or discharging the battery. Said method also comprises a step for measuring the current passing through the battery during application of said instruction. Said method moreover comprises a step for calculating m x n mean errors (e
Tj (t

1≤ j ≤ m ,1≤ i ≤ n between the measured current and the theoretical current of the instruction in m x n time intervals ([t
i
j , t
i
j + T
j ])
1≤ j ≤ m ,1≤ i ≤ n , respectively. Said method also comprises a step for calculating, for each j between 1 and m, e
j =max(
e Tj (

摘要： The invention relates to a cooling device (1) that includes a main cooling circuit (2) capable of adjusting the temperature of a thermal member (4), a secondary cooling circuit (3) including a first assembly (9) of at least two heat exchangers (10, 11) mounted in parallel, and a thermal coupling means (5) between the main cooling circuit (2) and the secondary cooling circuit (3). The cooling device (1) further comprises a temperature sensor (13) mounted in series on the secondary cooling circuit (3) and downstream from the first assembly (9), and a control unit including a first means capable of estimating, with a state monitor, the outlet temperature of each heat exchanger of the first assembly from the inlet temperature of a coolant at the inlet of each heat exchanger of the first assembly and from the values measured by the sensor temperature (13).
