AEM EV CCU Kit

The AEM EV Combined Charging Unit (CCU) combines both an On-Board Charger (OBC) and a DC-DC Converter (DCDC). The OBC charges the HV Battery Pack by taking 120v or 240v AC energy from the grid, converting it to high voltage DC and charging the high voltage battery in the vehicle. The DC-DC converter takes the high voltage from the battery pack and converts it to low voltage to maintain the charge in the vehicles 12V battery. The DC-DC converter performs the duties that the alternator does in an ICE vehicle. The CCU is fully controlled by the VCU via the CAN bus and the OBC and DC-DC report voltage, current and status information back to the VCU.

• The DCDC LV output is rated at 91.5% efficiency at full load with a max continuous DCDC output of 178A @ 14V
• Compact design (275mm x 202mm x 68mm =3.8L volume) - 2.5x to 3x smaller than comparable units
• Lightweight (5.5kg, ~12 pounds) comparable units are typically 18-24 pounds
• Liquid cooled and temperature controlled for efficient thermal management
• The HV battery charger is rated at 93.5% efficiency at full load
• 6.6kw (32 amps) on board charger + 2.5kw DC-DC converter
• High voltage output over and under voltage protection
• High and low voltage output short circuit protection
• The CCU has the following protection functions:
• 350Vdc nominal output and up to 450Vdc max
• Input over and under voltage protection
• Plug-and-play with AEM's EV controls
• Over temperature protection

Most of our parts are ordered from suppliers in the United States after your order is confirmed, so they travel in two legs: international shipping to our warehouse in Riyadh, then local delivery to you.

1. Orders within Saudi Arabia

1. We confirm your order and send it to the supplier, usually within one business day.
2. It ships from the United States to our Riyadh warehouse via DHL, and we email you the tracking number as soon as it ships.
3. Once received and inspected, we ship it to you, or deliver it directly if you are in Riyadh.

Estimated time: 10 to 20 business days from order confirmation for parts in stock at the supplier. The expected time for each product is shown on its page.

Cost: international shipping, customs duties and clearance fees are calculated and shown to you in full before payment. You will not be asked to pay anything extra on delivery.

2. GCC orders

• Shipped directly from the supplier to your address.
• The checkout includes shipping only; the customer is responsible for customs duties and taxes in the destination country, paid to the carrier on delivery.
• Refusing a shipment because of these charges is not a product defect, and the actual shipping and return costs will be deducted from the refund.

3. Special orders and out-of-stock parts

Some parts are not in the supplier's stock and are sourced on special order, which can take several weeks.

• The product page marks the item as a "special order" with its expected lead time.
• Before payment we confirm the expected delivery date with you in writing, and that date is the agreed delivery date.
• If the supplier is delayed we notify you as soon as we know and offer a new date. You may accept it, or cancel the order for a full refund.
• If delivery is more than 15 days late beyond the agreed date, you may cancel and receive a full refund.
• The 7-day return right from receipt also applies to special orders, unless the part was made to your specifications.

4. Receiving the shipment and damage

• Inspect the package on delivery; if it is visibly damaged, photograph it before opening.
• Report any damage or missing items within 7 days of receipt with photos of the part, the packaging and your order number.
• Transit damage is our responsibility: replacement or a full refund, as you prefer.

5. Address and details

You are responsible for the accuracy of your address and mobile number. If a shipment is returned because of a wrong address or failed contact, the actual cost of re-sending may be charged.

6. Items that cannot be shipped by air

Some products (such as fluids, aerosols and batteries) cannot be shipped by air and are not offered for sale. If this becomes apparent after ordering, we will cancel the order and refund it in full.
