Electrical automobiles are fastidiously designed with “consideration to element”. Ignoring or not respecting that element can have severe penalties, based on the EV automaker chief.
Technicians must deal with automobile design, Jake Rodenroth, supervisor of physique restore program operations at Lucid Motors, advised attendees on the 2022 Know-how Convention hosted by the Automotive Aftermarket Suppliers Affiliation.
For instance, a sizzling coolant line cannot contact one thing that is not meant to be sizzling.
“So when the whole entrance finish of the automobile is worn out and also you’re reassembling and all these sorts of issues are taken into consideration in how the automobiles are reassembled,” he defined. “In case you’re not delicate to these sorts of issues, you possibly can create an issue that is very totally different in a gasoline automobile.”
Qualification is crucial — if a technician is not correctly educated, he ought to keep away. Most EVs have a 400 V structure. Some are 800, others are 900 volts. These automobiles can damage you and vice versa.
“The factor about EVs is that as a repairer, you possibly can both damage them, or they will damage you. So in case you’re not certified to work on one, you possibly can by no means be authorized.” Have not gone via the coaching and do not have authorized tooling, it isn’t value doing one thing like this till you do,” Rodenroth defined.
Some techs will wish to apply the identical tips they use when engaged on a standard inside combustion engine – study as they go. it is a dangerous concept.
“There appears to be an entire bunch of repairmen on the market prepared and in a position to begin studying on buyer automobiles and that might be a giant downside in EVs,” Rodenroth mentioned. “You are both going to harm your self, or you are going to injury a really costly part in a high-tech automobile. And I do not assume we wish both. That is why I take a look at the coaching and Cannot stress the tooling half sufficient.”
The whole lot an EV does is totally different than what an inside combustion engine automobile does, he mentioned. Even EVs from one model to a different can fluctuate enormously.
“Simply because they each eat energy doesn’t suggest they do the identical factor,” Rodenroth mentioned. “Be very delicate to the truth that Ford goes to separate from Chevy and Chevy, it should separate from Tesla, Tesla goes to separate from Rivian and positively Rivian goes to separate from Lucid.”
He additionally identified that aerodynamics is important for an EV. Lowering drag will increase battery vary. However some issues that improve aerodynamics additionally make issues tougher for repairmen. Take the door handles – these are normally recessed into the physique shell. The Tech wants to make sure that the automobile is in correct working order earlier than it’s handed again to the client.
“These are simply extra issues that we now have to diagnose and ensure that they’re working the best way they had been imagined to and designed to work,” Rodenroth mentioned.
