EVEMS ATC-201 vs. ATC-202: Which One Is Right for Your Home?

A Practical Guide for Canadian Homeowners Planning to Install a Level 2 EV Charger

Installing a Level 2 EV charger at home is one of the most convenient ways to enjoy electric vehicle ownership. However, many Canadian homeowners face an important question:

Does my existing electrical panel have enough capacity for an EV charger?

A traditional electrical service upgrade can be expensive and time-consuming. Fortunately, an Electric Vehicle Energy Management System (EVEMS) may offer an alternative.

Timely Electric, a Canadian electrical contractor and EVEMS manufacturer, offers two residential models: EVEMS ATC-201 and ATC-202.

Let's explore their differences and how to choose the right system for your home.

1. What Does an EV Energy Management System Do?

An EVEMS monitors electrical demand and controls EV charging according to the available electrical capacity.

When household electrical demand increases, the system can temporarily interrupt EV charging to help prevent the electrical service from becoming overloaded.

When sufficient capacity becomes available again, charging can resume automatically.

This allows homeowners to make better use of their existing electrical infrastructure without necessarily requiring an expensive service upgrade.

2. EVEMS ATC-201: For Common Residential Electrical Services

The EVEMS ATC-201 is designed for residential electrical services rated from 100A to 200A.

Key features include:

• Supports 100A, 125A, 150A and 200A electrical services.

• Supports 30A, 40A, 50A and 60A EV charger loads.

• LCD display for continuous electrical load monitoring.

• Automatic EV charging load management.

• QAI certified.

• BC Hydro rebate eligible, subject to program requirements.

• Made in Canada.

The ATC-201 is a practical choice for homeowners who want to install a Level 2 EV charger while making use of their existing electrical service.

3. EVEMS ATC-202: More Options for Smaller Electrical Services

Not every home has a 100A or 200A electrical service.

Some older homes have 60A, 70A, 80A or 90A services, which can make installing an EV charger more challenging.

The EVEMS ATC-202 expands compatibility to a wider range of residential electrical service sizes.

Key features include:

• Supports 60A, 70A, 80A, 90A, 100A, 125A, 150A and 200A electrical services.

• Supports 30A and 40A EV charger loads.

• LCD display for continuous electrical load monitoring.

• Automatic EV charging load management.

• QAI certified.

• BC Hydro rebate eligible, subject to program requirements.

• Made in Canada.

The ATC-202 is particularly useful for homeowners with smaller electrical services who want to explore Level 2 home charging without automatically committing to a major electrical upgrade.

5. Which EVEMS Should You Choose?

Choose ATC-201 if:

Your home has a 100A–200A electrical service and your planned EV charger requires a supported load rating, including higher charging loads up to 60A.

Consider ATC-202 if:

Your home has a smaller electrical service, such as 60A, 70A, 80A or 90A, or you need a 30A or 40A EV charging solution.

The correct selection depends on your existing electrical service, household loads, EV charger requirements and installation conditions.

A qualified electrician should evaluate these factors before installation.

6. Can an EVEMS Help Avoid an Electrical Panel Upgrade?

In many suitable installations, an EVEMS can help homeowners install an EV charger without upgrading the main electrical panel or service.

Depending on the property and the work otherwise required, avoiding a major electrical upgrade could result in substantial savings.

However, not every home is suitable. The existing equipment must be in safe condition, and the installation must comply with applicable electrical codes and local requirements.
