It is important to use properly rated tools
and personal protective equipment
when servicing electric vehicles.

hen servicing any hybrid
electric vehicle (HEV) or
battery electric vehicle
(BEV), safety must be the top priority.
Not only is it imperative to use the
correct tools and personal protective
equipment (PPE), but also to take
precautions that other technicians
in the shop are protected as well.
There is a full line of hand tools that
are necessary to use while repairing high
voltage systems. Hand tools that are tested
and certified for high voltage work are all
readily identified by both their color - a
mix of orange and yellow - and a label
that uses a symbol of two stacked triangles and "1000V" printed on the tool,
as shown on the KNIPEX wrench below.
These tools are fully insulated and
can provide protection up to 1,000V. A
visual inspection is necessary to make
sure there is no missing, broken, or
worn insulation prior to each use. If
there is even the slightest damage to
the insulation, it may allow high voltage to contact the user, creating a very
hazardous situation.
Another critical tool is a digital multimeter (DMM) that is built to a category
III, 1,000V standard. This tool, along
with category III test leads and ends
must be used when testing high voltage
systems. These electrical test tools allow
the user to test and monitor high voltages safely and have the voltage ranges
necessary to test HEVs and BEVs. It is
imperative to visually inspect the test
leads, connector ends, and the meter for
any cracks or other wear, and stop using
the tools if any flaws are detected.
One of the most important pieces of
PPE a technician will use is a pair of Class
0 insulated rubber safety gloves, rated to
1,000V. Insulated gloves are to be worn
anytime a technician is working on the
vehicle's battery or the inverter/converter. This includes when disconnecting or
connecting the battery service plug and
when using insulated tools.
Keeping others safe is as simple as
placing warning notices or caution tape
around the vehicle in order to communicate there is a potential risk of electrical
shock. Warning signs and hazard tapes
are available through many online sources
and brick-and-mortar stores.
It is important to remember that
using the correct tools will make working on electric vehicles safer as long as
they are used and inspected correctly.
