Does anyone have some basic safety "rules" or advice particular to working on or operating an electric vehicle?
I know to always turn off the breaker before working on wiring in my house. I know I need to disconnect a battery cable when working on certain things in my car. What do I need to know to safely work on my electric scooter?
To be more specific, here are a few questions I jotted down while wiring my Z for bank charging:
- Is there a correct procedure to disconnecting the batteries so you can work on the bike safely?
- If I get a shock from my five 12-volt batteries in series (60V), will it be lethal?
- Does anything on the bike retain a charge and remain dangerous after the battery series has been broken?
- Does it matter if I disconnect/reconnect the positive or the negative of a battery first?
- What is the safest procedure for connecting batteries in series? (Bat 1 Neg -> Bat 2 Pos -> Bat 2 Neg -> Bat 3 Pos -> etc ?)
- Are there special safety plugs that can or should be inserted into a battery terminal after a cable has been removed to prevent accidental contact?
- Do I need to remove an entire battery cable (both pos, neg ends) from the bike to be safe (prevent short) or is disconnecting one terminal good enough?
- If I only disconnect one positive or negative from the series, leaving the other end still connected, and that end touches something metal (or I touch it) will it spark?
- Do I need special, extra thick "boots" on the battery cables to hold back a spark if something metal comes near that terminal while the series is connected? Or are standard battery cable boots good enough for the 60 volts?
- If a battery cable end is exposed (no boot) while the series is connected, and something metal (or a person) touches it, will it spark?
- Is DC current more dangerous than AC?
- Who's brain can I pick locally? Is the average mechanic qualified to give advice on an EV, or do I need to find someone who works on semis, fire trucks and other large vehicles, or even an electrician?
- Would parking the bike in the sun, on a really hot summer day cause the batteries to become dangerous? Is there a temperature safety range for batteries?
