High-Voltage Handling And Storage Considerations: Hyundai

Posted on 11 July 2024

High-voltage (HV) vehicles have some special considerations for handling and storing HV batteries and other components. The dangers of HV batteries are potential even after removal which is why certain precautions are needed. Let’s see what Hyundai has to say.

Hyundai provides information about HV systems storage and handling. This information pertains to performing a repair of the HV system and is found in multiple areas of the shop manual or body repair manual (BRM).

Body Repair ➤ BRM ➤ General Safety Information And Cautions
Shop ➤ Battery Control Systems ➤ Handling Precautions For High Voltage Battery ➤ Guide For Storing, Transporting, And Disposing Of Battery System
Shop ➤ Hybrid Control System ➤ High Voltage Battery Handling Guide
Within HV part removal and Installation procedure

The General Safety Information And Cautions document provides warnings recommending insulated tools, placing removed HV parts on an insulated mat, and covering the HV parts with an insulated sheet.

The Guide For Storing, Transporting, And Disposing Of Battery System or High Voltage Handling Guide document provides a chart to guide a technician to determine the condition of the battery. Another chart includes damaged and undamaged battery storage, transportation, and disposal considerations.

Hyundai has a technical service bulletin (TSB) 23-EV-001H Electric Vehicle (EV) Battery Approval, Handling, And Replacement Procedures. Information found in this document includes:

Approved EV battery lifting equipment
Battery coolant
Receiving, handling, and storage instructions including forklift use
Scan tool usage for battery start up procedures
Confirm battery will take charge

Within removal procedures, there may be notes that state what type of material to place an HV part on. This may include recommendations such as wood or rubber mats.

All precautions, including placards and personal protective equipment (PPE), must be observed when performing repairs on HV vehicles. Make sure to utilize Hyundai repair information prior to beginning any repairs.
