Compact, safe clamps, and more than enough to wake an EV's 12V system. Keep it in the frunk or glovebox and top it off a few times a year.

Best winter car gear for an EV in Winter
An EV doesn't need a block heater or jumper cables for the traction battery, but it has a small 12V battery that runs the computers and door locks — and when that dies, the car is a brick. Cold also cuts range by 20–40% and makes tire pressure drop like any car's. The winter kit for an EV is smaller, but it's not nothing: a compact jump starter, the visibility basics, and the warmth kit for a roadside wait that doesn't end with a tow truck bringing gas.

Range in cold
Expect 20–40% less; precondition while plugged in
- ▸The 12V battery in most EVs is small and fails with little warning. A compact jump starter (GB40) connected to the 12V jump points wakes the car up; check your manual for the location.
- ▸Preconditioning the cabin and battery while plugged in preserves range. Heated seats and steering wheel use far less energy than cabin heat.
- ▸Tire pressure matters even more on efficiency — it drops ~1 PSI per 10°F.
- ▸All the visibility and traction gear still applies: beam wipers, winter fluid, a brush that reaches the roof, chains sized to the tire if you drive passes (EVs are heavy; confirm the chain rating).

2. Battery Tender Junior 800
8.6
/ 10
For an EV that sits for weeks (second car, winter storage), a maintainer on the 12V battery prevents the most common EV 'dead car' call.

Visibility gear doesn't care about the drivetrain. Beam blades plus -25°F fluid before the first storm.

EV roofs often carry a glass panel — a foam broom clears snow without scratching it.

- ▸Never try to jump-start the high-voltage traction battery; the jump points are for the 12V system only. The manual shows where.
- ▸A dead 12V battery means no door unlock on some EVs — know the mechanical key location.
- ▸Charging is slower in the cold; plan DC fast-charge stops with margin on winter road trips.
Frequently asked questions
Can you jump-start an electric car?
You can jump the 12V system — which is usually all that's needed to wake the car and let the high-voltage battery take over. Use a compact jump starter or cables at the manufacturer's designated 12V jump points; never touch the high-voltage system. Check the manual first.
How much range does an EV lose in winter?
Typically 20–40% at freezing temperatures and below, more with cabin heat running. Preconditioning while plugged in, using seat and wheel heaters, and keeping tires inflated recover some of it.
