This 120-minute webinar reviews safety concerns and precautions related to high-voltage circuits present in hybrid, plug-in hybrid, electric, and fuel cell hybrid vehicles. HV circuits are discussed in general to provide an understanding of "where the risk lies". The effects of electrical current on the human body are summarized and existing protective measures, along with the standards that govern such measures, are described. Specific issues related to vehicle development, service, and operation are explained, along with onboard fault detection systems used to protect individuals from electrical injury. A general understanding of electrical and mechanical engineering is helpful, but is not required.

Registration for this live webinar is available on a per-person basis, similar to purchasing a seat in a classroom. Participants attend an online session from work or home; anywhere with a PC with internet access (at least 56K) and a telephone. The fee includes one connection to the two hour conference call (toll free telephone number provided for U.S. and select countries*) and assigned personal ID number; one connection to SAE's online training center (via WebEx); and access to a secure course in the SAE Learning Center that contains the webinar presentations, class session recordings, supplemental materials, and assignments.
*Global toll-free telephone numbers are provided for many countries outside the U.S., but are limited to those on the WebEx call-in toll-free number list. Check here to see if your country has a global call-in toll free telephone number for this webinar. If your country is not listed, you may still connect to this webinar using the US/Canada Call-in toll number or Voice over Internet Protocol (VoIP).
NOTE: The live course presentation will be recorded and made available for 30 days to those who register by the deadline but are unable to attend on the date/time listed above.Multiple Seat Discount - 50% off more than one!
- Register for this webinar at the list or member price and enjoy a 50% discount off the list price of the other hybrid webinars in this series (includes C0903, C0905, C0906).
- Register one individual at the full list or member price, then register as many additional employees at half off the list price. To receive the discount, register all individuals at the same time or mention the confirmation number for the first registrant. The offer is good for only the same webinar series and dates. All registrants will receive a personal account and opportunity for CEUs.
Registrations will be accepted until 5:00 p.m. the day before the start of the webinar. A full refund is issued if you notify SAE at least 14 days prior to the webinar start date. If canceled less than 14 days prior, the full fee is charged. Canceling may reduce group or multi-webinar discounts. For the SAE Member registration fees, member dues must be current. NOTE: SAE reserves the right to cancel webinars and cannot be held responsible for related costs incurred by registrants other than the registration fee.
