The high-voltage (HV) battery in an electric bus is connected to the rest of the bus through a high-voltage junction box (HVJB). The HVJB contains fuses, contactors, and sensors that distribute the HV power to the other subsystems. 
 
Here are some other things to know about the HV battery in an electric bus: 
 
Safety
When the bus is off, main contactors isolate the battery and the traction inverter for safety. 
 
Charging
A pre-charge contactor is used to charge the DC link capacitor before closing the main contactors. This helps avoid high inrush currents that can damage the battery, power contactors, and DC link capacitor. 
 
Handling
Only qualified personnel should work on or near the HV battery, as it operates at dangerous voltage levels. 
 
Maintenance
Unusual operating conditions, such as environmental conditions, may require more frequent service.
