Basic requirements: electronic and control system maintenance ability, high-voltage electrical system operation and maintenance ability, mechanical equipment maintenance ability, fault analysis and hardware maintenance ability, daily maintenance ability.
Protective tools: insulating work shoes, insulating gloves, goggles, safety helmet and maintenance clothes.
Protective measures: Insulating gloves are required for high-voltage installation of pure electric new energy vehicles, insulating glue is applied to bolts and fasteners, insulating flame-retardant tape is applied to partitions, and exposed poles are wrapped with insulating tape in time during installation to keep them clean.
Interpretation of various abilities:
1, electronic and control system maintenance capability
The biggest difference of new energy vehicles is that they have complex electronic and control systems. Maintenance personnel need to be familiar with the functions and principles of electronic and control systems, and can maintain the electronic control unit (ECU).
2, high voltage system operation and maintenance ability
The safety management and daily operation of the high-voltage electrical system of new energy vehicles require higher maintenance personnel. Maintenance personnel need to know the relevant knowledge of high-voltage electrical system, such as voltage and current characteristics, and master the skills of maintenance, overhaul and troubleshooting of high-voltage electrical system.
3, mechanical equipment maintenance ability
In the process of maintenance, new energy vehicles also need mechanical repair and maintenance. Maintenance personnel need to have basic knowledge of automobile structure and performance, and be familiar with the maintenance methods and skills of automobile mechanical parts.
4, fault analysis and hardware maintenance ability
The core technologies of new energy vehicles include software and hardware, and the ability of fault analysis and hardware maintenance is a professional ability that a qualified maintenance personnel must have. Better analysis ability and maintenance ability can bring higher protection to customers.
5, the ability of daily maintenance
The maintenance of new energy vehicles also needs some daily maintenance work, such as vehicle driving inspection, parts replacement and daily maintenance. Therefore, maintenance personnel need to have the ability of daily vehicle maintenance.
? Reason:
Because the new energy vehicle itself has high voltage, and the thickness of slag fiber is high, it is necessary to disconnect the high voltage during maintenance. For the safety of maintenance personnel, high-voltage detection is generally carried out, and insulation protection measures should be taken when maintaining high-voltage components of new energy vehicles.
Another kind of high-voltage circuit has a large current. In the process of high-voltage power failure of new energy vehicles, the low-voltage circuit is usually cut off first, and then the high-voltage circuit is cut off, so as to avoid misoperation and high-voltage electrification during maintenance, causing casualties.
