Jeep 4xe Level 1 Charger Installation

In this guide, we will focus on Jeep 4xe Level 1 charger installation, since most users who requested this post termed they are forced to use the Level 1 EV charger due to electrical configurations support for only Level 1 Jeep 4xe charging, or integration of renewable energy Jeep 4xe charging we will give detailed installation processes on a 110V electrical circuit which requires three different wires: hot, neutral, and ground.

Best Jeep 4xe Level 1 Charger

Before the Jeep 4xe Level 1 charger installation processes, you must make sure you have a Jeep 4xe Level 1 charger which is set at delivering 15 amps of current, we recommend using the original OEM Jeep 4xe Level 1 EV charger, although if you don’t have it, you can purchase an aftermarket Level 1 EV charger to trickle charge your Jeep 4xe.

Installing a 15 amps Level 1 Jeep 4xe charger is ideal for 110V-120V electrical circuits, this setup recharges a Jeep 4xe 17 kWh lithium-ion battery in about 12 hours.

Below are some of the recommended 15-amp aftermarket Level 1 EV chargers that are compatible with your Jeeo 4xe.

Lectron Level 1 EV Charger

We recommend the Lectron Level 1 EV charger as a cheaper alternative to the original OEM Jeep 4xe Level 1 EV charger, the Lectron Level 1 Charger operates on a standard 110V outlet, providing 15 amps and 1.65 kW of power. Overnight Jeep 4xe charging at home is practical, delivering an all-electric Jeep 4xe maximum range of up to 21 miles on a full battery charge without the expense of a Level 2 charger.

Safety-wise, it’s FCC and ETL certified with protections against overvoltage, overcurrent, and short circuits. Its portability also makes it handy for road trips or charging at different locations. The charger is compatible with J1772 standards.

Pre-Installation Assessment

The first step in installing your Jeep 4xe level charger is determining the Level 1 charger point of use, this will dictate whether you will need an electrical panel extension closer to the point of use to mitigate voltage drops when charging your Jeep 4xe.

When using a Jeep level 1 EV charger, you would require continuous loads of 15 amps to charge the 17kWh lithium-ion battery, the Jeep 4xe 32 amps onboard charger regulates how much current can be drawn from the charger in this case 15 amps although the charger is capable of handling 32 amps.

The image below illustrates the operation of the Jeep 4xe’s 32-amp onboard charger under two different conditions: first, when connected to a 15-amp Level 1 EV charger, and second, when connected to a 32-amp Level 2 EV charger. It also shows the respective times required to fully recharge the 17 kWh lithium-ion battery in each scenario.

When installing a 15 amps Jeep 4xe Level 1 Charger, we recommend using a 20 amps circuit breaker to adhere to the 80/20 rule on continuous loads, this rule dictates that electrical branch circuits supplying continuous loads such as Level 1 EV charging should not exceed 80% of their capacity to prevent overheating and ensure safe EV charging.

A typical Level 1 EV charger installation should mirror the Jeep 4xe Level 1 charging branch circuit shown below:

Includes a 15-amp Level 1 EV charger for Jeep Wrangler 4xe.

Electrical Panel Assessment

When accessing the electrical panel for a Jeep 4xe 15 amps charger installation, it’s crucial to determine whether your electrical panel can support an additional 15 amps of continuous load without overloading your electrical panel.

The second assessment you should take into account is to make sure the electrical panel has a breaker slot so that you can install a dedicated 15-amp circuit breaker. You would also need Wireway or “wire channel” space to fit the 12 AWG wires that you will use to connect the circuit breaker and the 15-amp Jeep 4xe charger outlet.

Most Jeepers with a Level 1 EV charger later upgrade their electrical panel for smart EV charging features by installing smart EV charging accessories such as a smart meter into another electrical panel to enjoy smart EV charging while using a Level 1 EV charger, for this reason, its important to make sure your electrical panel would have enough spacing to fit the added accessories you might require in the future.

For Jeepers looking to integrate renewable energy EV charging such as using solar power, they might prefer Level 1 EV chargers over Level 2 EV chargers because of the power requirements and cost perspectives.

A Level 1 charger draws around 1.65 kW, matching the output of some smaller solar panel systems. This can be advantageous if your solar setup is modest and primarily focused on offsetting your daily driving needs which is both cost-effective in terms of purchasing the chargers and renewable energy systems required to charge a Jeep 4xe.

FeatureLevel 1 Jeep 4xe ChargerLevel 2 Jeep 4xe Charger
Power RequirementsLower (around 1.65 kW)Higher (6 kW to 19.2 kW)
Cost (Upfront)LowerHigher (charger installation)
Suitability for SolarGood for overnight charging with sufficient solar generationGood for faster charging with excess solar generation during the day.

For Jeepers looking to integrate renewable energy EV charging into their level 1 Jeep 4xe charging, they should make sure their electrical panel has sufficient space and capacity needed to integrate renewable energy EV charging accessories such as transfer switches, dedicated circuit breakers, sensors and cabling to connect all the accessories.

The image below shows a typical setup for charging a Jeep 4xe using a Level 1 EV charger. This charger is connected to a solar-powered circuit specifically designed for EV charging.

It specifies a shunt trip 20 amps breaker and a 15-amp Level 1 EV charger connected to the Jeep Wrangler 4xe, all contained within a 1-¼" conduit rated at 90° C+.

Electrical Panel Upgrade

Depending on your electrical panel load and capacity various factors might necessitate an electrical panel upgrade depending on the complexity of your Level 1 Jeep 4xe charger installation, although a 100 amp electrical panel is sufficient for Level 1 Jeep 4xe charging, you might require an electrical panel upgrade such as upgrading your main electrical panel to a 200 amps electrical panel or opting for a dedicated 100 amps EV charging electrical sub panel.

Now that you have a compatible Level 1 Jeep 4xe charger, a compatible electrical panel that can fit an 20 amps circuit breaker, and the cables depending on the complexity of your Jeep 4xe Level 1 charger installation, it is time for the next steps, installing the charger.

Installing a Level 1 Jeep 4xe Charger Main Panel Installation

To install a Level 1 Jeep 4xe charger in your main electrical panel, the electrical panel should have a breaker slot that can accommodate a 20 amps circuit breaker and enough room for 12 AWG cables required to connect the NEMA 5-15R outlet for plug-in installation or a Junction box for hardwiredLevel 1 Jeep 4xe charger.
