High Voltage Network

General Requirements

EV4.1.1 The maximum permitted voltage that may occur between any two electrical connections is 600VDC and for motor controller/inverters internal low power control signals 630VDC.

EV4.1.2 All components in the TS must be rated for the maximum TS voltage.

The TS area of a PCB, see EV4.3.6, is considered as one component.

Every input connected to the TS must be rated to the maximum TS voltage.

EV4.1.3 All components must be rated for the maximum possible temperature which may occur during usage.

EV3.2.1 All electrical systems must have appropriate overcurrent protection.

EV4.3.1 The entire TS and LVS must be galvanically isolated, see EV1.2.1 and IN4.1.1.

EV4.3.2 All connections from a TS component to external devices, such as laptops must include galvanic isolation, see EV1.2.1.

SRR

HV network contains every part of the vehicle that carries voltage higher than 60V DC or 50V AC RMS, the network contains mainly the TS and parts of its monitoring and control.

The HV network has and interface / contains the following systems:

· Accumulator

· Inverter

· Motor

· BMS

· DC-DC converter

· AIR's

· Precharge Circuit

· Discharge Circuit

· TSAL

· Current Sensor

· Data Logger

· Voltage Indicator

· IMD

· TSMS's

· TSMP's

· HVD

· HV components (Connectors, cables etc)
