Keeping your EV charged at home shouldn’t require a costly electrical panel upgrade. Many households are limited by a single 40‑ or 50‑amp circuit and can’t add multiple 240‑V lines. Load sharing (also called dynamic load balancing) solves this problem by intelligently distributing power among chargers so you can plug in more than one vehicle or charge without tripping breakers.
Why Load Sharing Matters
Load management technology intelligently distributes electrical power among multiple EVs to prevent grid overloads and optimize energy use. It monitors real‑time demand, adjusts charging speed dynamically and reduces the chance of tripped circuits. Load sharing goes a step further by allowing multiple EVs to share a single circuit; power is allocated based on priority (for example, battery level), which is ideal for homes with limited electrical capacity. Without it, each charger often needs its own dedicated 240‑V circuit, which increases installation cost and may not be possible in older panels.
Top Load‑Sharing EV Chargers in 2025
1. Wallbox Pulsar Plus
Wallbox’s Pulsar Plus is one of the only mainstream residential chargers that natively supports power sharing. You can connect up to three Pulsar Plus units to a single circuit and the chargers will communicate to share power while still delivering enough current to each vehicle. Key features include:
- Dynamic load balancing and energy management: Wallbox’s energy‑management suite can increase or decrease charging speed based on your home’s real‑time power demand. It uses a separate power meter (≈ $279) to enable dynamic load balancing.
- Connectivity & smart control: Wi‑Fi and Bluetooth enable scheduled charging and remote control. The charger has on‑board intelligence, so it continues working even if your internet is down.
- Solar integration & voice control: The Eco‑Smart feature allows charging from 100 % solar power or a mix of solar and grid energy. It also supports voice commands via Amazon Alexa or Google Home.
- Price & warranty: The 40‑A model costs about $649 and the 48‑A model about $699. It comes with a three‑year warranty.
When to choose: If you need to charge more than one vehicle on a limited circuit or want a charger ready for solar integration and smart‑home automation, Pulsar Plus is a versatile choice.
2. Tesla Gen 3 Wall Connector
Tesla’s Wall Connector doesn’t just charge Tesla vehicles – the company offers a NACS‑to‑J1772 adapter for other EVs. Its Power Management suite includes three modes that help households avoid costly panel upgrades:
- Static Power Management lets the installer set a maximum current (multiple fixed levels) so the charger never exceeds your panel’s capacity.
- Dynamic Power Management uses a Tesla‑approved power meter to continuously monitor available power and adjust the charging rate in real time, ensuring the fastest possible charge while keeping total panel load within safe limits.
- Group Power Management allows up to six Gen 3 Wall Connectors to share power from one circuit, distributing energy among multiple vehicles and eliminating the need for separate circuits. This is ideal for households with more than one EV but limited electrical capacity.
These features together provide a robust load‑sharing solution that doesn’t require Wi‑Fi and works even during internet outages. Dynamic Power Management requires installing a power meter, and Group Power Management works only among Gen 3 Wall Connectors.
When to choose: Homeowners with multiple EVs, especially Tesla vehicles, who want a scalable solution can install one or more Wall Connectors and enable Group Power Management to share power across up to six units.
3. Emporia Smart Home EV Charger
While Emporia’s Level 2 charger does not offer native load sharing, it is a budget‑friendly option with energy monitoring that can help manage panel limitations. The charger delivers quick charging speeds and comes with all the relevant safety certifications. It is available with Tesla or J‑1772 connectors and has excellent user ratings (4.7/5 at Amazon).
Emporia’s system shines when paired with the Emporia Vue energy monitor, which lets you see detailed consumption data and even enables a charge‑from‑solar mode. Although it lacks built‑in load sharing, you can set lower current limits in the app to prevent overloading a limited circuit. Note that Emporia does not offer a dual‑cable charger or 80‑A capacity.
When to choose: If you’re looking for a lower‑cost charger with energy monitoring and you’re comfortable manually adjusting amperage to suit your panel, Emporia’s charger is an excellent value.
4. ChargePoint Home Flex
ChargePoint’s Home Flex is a popular, ENERGY STAR‑certified charger with adjustable amperage settings from 16 A to 50 A. However, it does not support power sharing – each unit requires its own dedicated 240‑V circuit. Key details:
- Models & price: Available in plug‑in (NEMA 6‑50 or 14‑50) and hardwired models; starting at $549 for hardwired and $599 for plug‑in versions.
- Adjustable amperage: You can match the charge rate to your home’s electrical wiring, making it possible to charge up to 12 kW / 50 A or dial it down to as low as 16 A.
- Long cable & app: Comes with a 23‑ft cable and a user‑friendly app with Wi‑Fi connectivity and over‑the‑air updates. The charger is waterproof (NEMA 3R) and can be installed indoors or outdoors.
- Efficiency: ENERGY STAR certification means it uses about 40 % less energy in standby mode than standard chargers, helping reduce emissions.
When to choose: Ideal if you need adjustable power levels and a polished app experience and don’t require multiple chargers on a single circuit. For load sharing, you would need a separate load management device.

|---|---|---|---|---|
| Wallbox Pulsar Plus | 40 A or 48 A | Shares a single circuit across up to three units; dynamic load balancing with power meter | Voice control, solar‑charging modes, offline operation | $649–$699 |
| Tesla Wall Connector (Gen 3) | 48 A | Static & dynamic power management; Group Power Management supports up to six connectors | Works without Wi‑Fi; dynamic adjustment via power meter | ≈ $475 (charger) + power meter cost; installation varies |
| Emporia Smart Home Charger | 48 A | None (manual amperage setting) | Energy monitoring, solar‑integration with Emporia Vue | ≈ $449 (charger) |
| ChargePoint Home Flex | Up to 50 A | None – requires dedicated circuit | ENERGY STAR certified, long cable, robust app | $549–$599 |
Tips for Installing Load‑Sharing Chargers
- Consult a licensed electrician. Regardless of the charger you choose, always hire a certified electrician to evaluate your panel and install the equipment. Proper installation prevents hazards and ensures warranty coverage.
- Check panel capacity. Calculate your total load by adding the EV charger’s power draw to other household appliances. If the sum exceeds the panel’s rating, consider a load management device or an electric panel upgrade.
- Pair with solar for savings. Many load‑sharing chargers integrate with solar panels or work with third‑party energy monitors. Charging during the day or using excess solar production can reduce your electricity costs.
- Monitor and adjust. Even with load sharing, keep an eye on your energy use. Chargers like Wallbox Pulsar Plus and Emporia let you adjust amperage or schedule charging during off‑peak hours to avoid high utility rates.
