Components
This component/Unit distributes HV power throughout the vehicle
What is the HV PDU? or What is the High Voltage Power Distribution Unit
This oil must be used in Lightning's Mitsubishi electrically driven AC compressors.
What is POE oil? specifically POE-32
This internal component is responsible for disconnecting the batteries from the HV bus during a normal shutdown.
What are Contactors?
This type of charging uses standard 120V AC wall power.
What is Level 1 *or* L1?
This component is responsible for converting ~400V to ~12V to run the low voltage systems and recharge the 12 volt battery.
What is a DCDC *or* DC to DC Converter? Specifically Net Power combo units on Lightning vehicles
This coolant loop uses the OEM radiator and fans for cooling.
What is the PETM *or* Power Electronics Thermal Management coolant loop?
(bonus) Why?
Removing this component breaks the HV circuit within the battery pack.
What is the MSD *or* Manual Service Disconnect?
This type of charging requires the charge handle locks in place while current is being delivered.
What is DC Fast Charging? *or* Level 3 charging *or* L3 charging
This on-board component is responsible for rectifying AC to DC for charging while the vehicle is not in motion.
What is the Level 2 charger? *or* OBC
If the cabin AC isn't working, this component might be susceptible to overheating. (Not Driver or passengers)
What are the HV Batteries?
The low voltage signal line is used to ensure all HV connections are closed.
What is the HVIL (High Voltage Interlock Loop)?
Charge speeds are fastest within this SoC range.
What is approximately 20% to ~80%?
This component has a HV DC connection, 12V supply connection, and a HV (orange) AC connection. (Not TINV)
What is the Netpower module? *or* Combo unit *or* DCDC/L2
This coolant loop interfaces with a freon cooled chiller for increased cooling capability
What is the BTMS? *or* Battery Thermal Management
High voltage leakage to the chassis causes this type of failure.
What is an Isolation failure?
The reason to equip two level 2 chargers (Net Power) instead of just one.
What is "half the charge time"?
Capable of 12 kW charging speed at L2.
Energy flow through this component can be from a HV DC input to HV AC output, OR a HV AC input to HV DC output.
What is the Traction Inverter?
On the GM4500, the PETM coolant loop provides thermal control to these 4 components.
What are the Inverter, Motor, DCDC/OBCM (x2), and Gearbox?
These two circuits/systems are responsible for dissipating HV energy within the HV bus.
What are the Active and passive discharge circuits?
In addition to the On Board Charger and the HV batteries, these 2 other subsystems/functions might also be running during a keyed-off charge session.
What are the BTMS and DCDC?
