Patent number: 12157375Abstract: An on-board battery charger (OBC) includes (i) rail circuits having respective rail controllers and (ii) a main controller. The rail controllers sample voltages supplied to their rail circuits and transmit a fault signal to the main controller upon a comparison between a sampled voltage and a threshold being affirmative of an improper voltage condition (overvoltage or undervoltage) of the sampled voltage. The main controller controls all of the rail controllers to stop operation of all of the rail circuits in response to receiving the fault signal from any of the rail controllers. In a variation, the main controller samples the voltages supplied to the rail circuits and stops operation of all of the rail circuits upon a comparison between a sampled voltage and the threshold being affirmative.Type: GrantFiled: September 27, 2021Date of Patent: December 3, 2024Assignee: Lear CorporationInventors: Victor Saborido Rodriguez, Sergio Martinez Porras, Antonio Martinez Perez, Adria Marcos Pastor

Publication number: 20230238805Abstract: An on-board battery charger (OBC) includes a converter (e.g., a DC/DC converter) and a controller. An output port of the converter is connectable to a battery (e.g., a traction battery of an electric vehicle (EV)) via a voltage network (e.g., a high-voltage (HV) network of the EV). The converter converts an input power into an output power and outputs the output power onto the voltage network for charging the battery. The controller, upon detecting a transitory disconnection in the voltage network, controls the converter to stop converting the input power into the output power. In stopping the converter, the controller stops the converter prior to a corresponding reconnection in the voltage network. The controller may detect the transitory disconnection upon detecting a switching frequency of a power switch of the converter decreasing below a pre-defined threshold as the switching frequency decreases due to effects of the transitory disconnection.Type: ApplicationFiled: January 25, 2022Publication date: July 27, 2023Applicant: LEAR CORPORATIONInventors: Adria MARCOS PASTOR, Antonio MARTINEZ PEREZ, Sergio MARTINEZ PORRAS

Publication number: 20220247199Abstract: An on-board battery charger (OBC) includes first and second rails which generate first and second detection signals based on voltage events, such as zero-crossing or peak voltage events, of input voltages supplied to the rail circuits. The OBC includes a relay switchable between (i) an opened state in which the relay disconnects the rails whereby the rails can respectively receive first and second phase input voltages from a multi-phase mains supply and (ii) a closed state in which the relay connects the rails whereby the rails can both receive a same input voltage from a single-phase mains supply. A controller determines from a comparison of the detection signals at the same time whether input voltages received by the rails from a mains supply are out-of-phase or in-phase to determine therefrom whether the mains supply is multi-phase or single-phase and/or whether the relay is properly or improperly opened or closed.Type: ApplicationFiled: October 25, 2021Publication date: August 4, 2022Applicant: Lear CorporationInventors: Jordi TOST BARTOLOME, Cesar RUANO ALVAREZ, Josep RUIZ RODON, Andre CARTAXO, Adria MARCOS PASTOR

Patent number: 11368035Abstract: An on-board charger (OBC) for an electric vehicle includes a charge unit, a controller, and a control pilot (CP) wake-up circuit. The charge unit is operable for receiving energy from an EVSE for charging a traction battery of the vehicle. The controller while awake can control the charge unit to charge the battery with energy from the EVSE. The CP wake-up circuit receives a control pilot (CP) signal from the EVSE, detects for a change in a current state of the CP signal while the controller is asleep, and generates a wake-up signal for waking up the controller in response to the current state of the CP signal changing to a new state. The CP wake-up circuit includes first/second detector circuits usable for detecting for a change in the current state of the CP signal to a first/second new state.Type: GrantFiled: March 27, 2020Date of Patent: June 21, 2022Assignee: LEAR CORPORATIONInventors: Adria Marcos Pastor, Alberto Martinez Ramirez, Antoni Amenos Murtra, Edgar Zahino Andres

Publication number: 20220176838Abstract: An on-board battery charger (OBC) of an electric vehicle (EV) receives AC electrical power from a charge station and outputs a DC output current for charging a traction battery of the EV. In response to transients in the AC electrical power while the OBC is receiving the AC electrical power from the charge station and outputting the DC output current, a controller controls the OBC to (i) stop processing the AC electrical power from the charge station and reduce the DC output current and (ii) after the transients have passed, resume processing the AC electrical power from the charge station and increase the DC output current. For instance, at a zero-crossing event of the AC electrical power after the transients have passed, the OBC is controlled to resume processing the AC electrical power from the charge station and increase the DC output current.Type: ApplicationFiled: September 7, 2021Publication date: June 9, 2022Applicant: Lear CorporationInventors: Victor SABORIDO RODRIGUEZ, Cesar RUANO ALVAREZ, Adria MARCOS PASTOR, Sergio MARTINEZ PORRAS

Patent number: 11271473Abstract: An on-board charger (OBC) for using AC power to charge a traction battery of an electric vehicle includes a DC/DC converter and a controller. The converter receives input power including a voltage having a DC voltage component and a voltage ripple varying at a frequency of the AC power. The controller generates a control signal for controlling the converter to convert the input power into an output power having a current for charging the battery. The controller includes a filter which enhances a sensed value of the current at the frequency to generate a locally-enhanced sensed value of the current. The controller determines a difference between a target and the locally-enhanced sensed value of the current and generates the control signal based on the difference such that the converter in converting the input power into the output power in response to the control signal adapts the current to the target.Type: GrantFiled: July 26, 2019Date of Patent: March 8, 2022Assignee: Lear CorporationInventors: Antonio Martinez Perez, Adria Marcos Pastor, Antonio Leon Masich, Roberto Giral Castillon, Javier Calvente Calvo, Enric Vidal Idiarte, Hugo Valderrama Blavi

Patent number: 10855169Abstract: An on-board charger (OBC) for charging a traction battery of an electric vehicle includes a primary phase, a secondary phase, and a pre-charge circuit. Each phase includes a circuit having an input and an output. The primary phase circuit input is connectable to a mains supply to connect the primary phase to the mains supply. The secondary phase circuit input has an input capacitor. The pre-charge circuit is connected between the circuit outputs and is switchable between an opened state in which the pre-charge circuit disconnects the circuit outputs and a closed state in which the pre-charge circuit connects the circuit outputs. When the pre-charge circuit is in the closed state, an electrical current may flow through the pre-charge circuit from the primary phase circuit output to the secondary phase circuit output and through the secondary phase circuit to the input capacitor to charge the input capacitor.Type: GrantFiled: September 10, 2019Date of Patent: December 1, 2020Assignee: Lear CorporationInventors: Adria Marcos Pastor, Josep Maria Bosque, Alberto Martinez Ramirez, Antonio Martinez Perez, Victor Saborido Rodriguez, Edgar Zahino Andres
