Lexus - UX300e - Owners Manual - 2020 - 2020

UX300e KMA10 Series Foreword This guide was developed to educate and assist dismantlers in the safe handling of Lexus UX300e electric vehicles. UX300e dismantling procedures are similar to other non-electric Lexus vehicles with the exception of the high voltage electrical system. It is important to recognize and understand the high voltage electrical system features and specifications of the Lexus UX300e electric vehicle, as they may not be familiar to dismantlers. High voltage electricity powers the compressor with motor assembly, electric motor, DC/DC converter, electric heater, and inverter with converter assembly. All other conventional automotive electrical devices such as the head lights, radio, and gauges are powered from a separate 12 V auxiliary battery. Numerous safeguards have been designed into the UX300e to help ensure the high voltage, approximately 355.2 V, Lithium-ion (Li-ion) traction battery assembly is kept safe and secure in an accident. The Li-ion traction battery assembly contains sealed batteries that are similar to rechargeable batteries used in some battery operated power tools and other consumer products. The electrolyte is absorbed in the cell plates and will not normally leak out even if the battery is cracked. High voltage cables, identifiable by orange insulation and connectors, are isolated from the metal chassis of the vehicle. Additional topics contained in the guide include: • Lexus UX300e identification. • Major electric vehicle component locations and descriptions. By following the information in this guide, dismantlers will be able to handle UX300e electric vehicles as safely as the dismantling of a conventional non-electric automobile.  2020 Toyota Motor Corporation All rights reserved.

Electric Vehicle means that the vehicle contains only an electric motor and does not have a gasoline engine for power. Electricity is stored in a high voltage traction battery assembly for the electric motor. The following illustration demonstrates how the UX300e operates in various driving modes.  A plug-in charge control system has been adopted, which allows electrical power to be supplied to the high-capacity traction battery from external power source such as an electrical socket or charger. The plug-in charge control system supports 2-types of charging, AC charging and DC charging.  During driving, the vehicle will drive using electric power.  During deceleration, such as when braking, the vehicle regenerates the kinetic energy from the front wheel to produce electricity that recharges the traction battery assembly.  While the vehicle is stopped, the electric motor is off, however the vehicle remains on and operational.  Plug-in Charging  Driving Plug-in Charging Electricity  Deceleration Charging batteries 1  Stopped UX300e Identification In appearance, the 2020 model year UX300e is nearly identical to the conventional, non-electric Lexus UX.

Auxiliary Battery • • The UX300e contains a sealed lead-acid 12 Volts battery. This 12 Volts auxiliary battery powers the vehicle electrical system similar to a conventional vehicle. As with other conventional vehicles, the negative terminal of the auxiliary battery is grounded to the metal chassis of the vehicle. The auxiliary battery is located in the motor compartment. 12 Volt Auxiliary Battery Mounted in Motor Compartment 355.2 Volt Traction Battery Assembly Traction Battery Assembly Mounted in Under the Floor 10 High Voltage Safety The traction battery assembly powers the high voltage electrical system with DC electricity. Positive and negative orange colored high voltage power cables are routed from the traction battery assembly, under the vehicle floor pan, to the drive unit (inverter and motor) and DC/DC converter. The inverter contains a circuit that boosts and inverts the 355.2 Volts DC from the traction battery assembly to 500 Volts AC to power the motor. The inverter with converter assembly creates 3-phase AC to power the motor. Power cables are routed from the inverter with converter assembly to each high voltage motor (electric motor, electric heater, and compressor with motor assembly). The following systems are intended to help keep occupants in the vehicle and emergency responders safe from high voltage electricity: High Voltage Safety System • Positive and negative high voltage power cables * connected to the traction battery assembly are controlled by 12 Volt normally open relays (system main relays *). When the vehicle is shut off, the relays stop electrical flow from leaving the traction battery assembly. WARNING: ・ The high voltage system may remain powered for up to 10 minutes after the vehicle is shut off or disabled. To prevent serious injury or death from severe burns or electric shock, avoid touching, cutting, or opening any orange high voltage power cable or high voltage component. • Both positive and negative power cables * are insulated from the metal body. High voltage electricity flows through these cables and not through the metal vehicle body. The metal vehicle body is safe to touch because it is insulated from the high voltage components. • A ground fault monitor in the electric vehicle computer * continuously monitors for high voltage leakage to the metal chassis while the vehicle is running. If a malfunction is detected, the electric vehicle computer * will illuminate the master warning light in the instrument cluster and indicate “EV System Malfunction” on the multi-information display. • The traction battery assembly contactors will automatically open to stop electricity flow in a collision sufficient to activate the SRS. *Numbers apply to the illustration on the following page. 11 Service Plug Grip • The high voltage circuit is cut by removing the service plug grip (see page 15). 0.0 Volt DC 0.0 Volt DC Charger Assembly 0.0 Volt DC ➌ Electric Vehicle Computer Compressor with ➊ Motor Assembly Electric Heater Inverter with Converter Assembly ➊ ➋ ➊ 0.0 Volt DC Electric Motor ➋ Battery ECU Assembly 0.0 Volt DC Battery Charger Controller AC 3-Phase 0V 12 Volt Auxiliary Battery High Voltage Safety System – Vehicle Shut Off (READY-OFF) 0.0 Volt DC 355.2 Volt DC 0.0 Volt DC Charger Assembly Electric Vehicle Computer Compressor with Motor Assembly Inverter with Converter Assembly Electric Heater 355.2 Volt DC Electric Motor Battery ECU Assembly 0.0 Volt DC AC 3-Phase 355.2V 12 Volt Auxiliary Battery High Voltage Safety System – Vehicle On and Operational (READY-ON) 12 Battery Charger Controller Precaution to be observed when dismantling the vehicle • • • • • • • • • • • • • • • To prevent electric shock, wear insulated gloves when working on wire harnesses and components of the high voltage system. Before using insulated gloves, be sure to check them for cracks, tears and other types of damage. When servicing the vehicle, do not carry metal objects like mechanical pencils or rulers that can be dropped accidentally and cause a short circuit. To reduce the risk of electric shock, make sure to remove the service plug grip to cut off the high voltage circuit before servicing the vehicle. To reduce the risk of electric shock, make sure to wait at least 10 minutes after removing the service plug grip to fully discharge the high voltage capacitor inside the inverter with converter assembly. Do not touch any high voltage wire harnesses, connectors or parts with bare hands. Do not touch the terminals of the service plug grip. Make sure to insulate the high-voltage connectors and terminals of the traction battery assembly with insulating tape after removing them. After removing the service plug grip, put it in your pocket to prevent other technicians from accident ally reconnecting it while you are working on the high-voltage system. Before touching a bare high-voltage terminal, wear insulated gloves and use a tester to make sure that the terminal voltage is 0 V. Electrolyte leaks may cause acute poisoning if a high concentration of the vapor from the electrolyte is inhaled. In case of inhalation, move the affected person to a place with ample fresh air and let them lie quietly. Seek medical care. If the electrolyte comes in contact with your skin, wash the area thoroughly with soap and plenty of water, and seek medical care. If the electrolyte comes in contact with an article of clothing, take it off immediately. Prolonged contact with the electrolyte may cause skin irritation. If the electrolyte comes in contact with your eyes, call out loudly for help. Do not rub your eyes. Immediately flush them with a large amount of water for at least 15 minutes and seek medical care. If electrolyte is swallowed, seek medical care immediately. Do not induce vomiting, unless instructed by the doctor. If the vehicle catches on fire, use an ABC fire extinguisher to extinguish the fire. Trying to extinguish a fire using only a small amount of water can be more dangerous than effective. Use a substantial amount of water or wait for firefighters. Do not allow any foreign matter or water to enter the traction battery assembly. Necessary Items • • • Protective clothing such as insulated gloves (electrically insulated), rubber gloves, helmet, safety goggles, safety shoes and SCBA or protective mask. Insulating tape such as electrical tape that has a suitable electrical insulation rating and insulation tool set. An electrical tester that is capable of measuring DC 750 Volts or more. 13 Spills The UX300e contains some of the same common automotive fluids used in other non-electric Lexus vehicles, with the exception of the Li-ion electrolyte used in the traction battery assembly. The electrolyte used in the Li-ion battery cells is a flammable organic electrolyte. The electrolyte is absorbed into the battery cell separators, even if the battery cells are crushed or cracked, it is unlikely that liquid electrolyte will leak. Any liquid electrolyte that leaks from a Li-ion battery cell quickly evaporates. WARNING: ・ The Li-ion battery contains organic electrolyte. Only a small amount may leak from the batteries which may irritate the eyes, nose, throat, and skin. ・ Contact with the vapor produced by the electrolyte may irritate the nose and throat. ・ To avoid injury by coming in contact with the electrolyte or vapor, wear personal protective equipment for organic electrolyte including SCBA or protective mask for organic gases. Handle Li-ion electrolyte spills using the following Personal Protective Equipment (PPE): • Splash shield or safety goggles. Fold down helmet shields are not acceptable for electrolyte spills. • • • • Butyl rubber or suitable organic solvent gloves. Apron or protective clothing suitable for organic solvents. Rubber overboots or boots suitable for organic solvents. Full face respirator suitable for organic solvents or SCBA. 14 Dismantling the vehicle The following 5 pages contain general instructions for use when working on a UX300e.
