The U.S. Environmental Protection Agency (EPA) recently released official documents for Tesla Cybertruck, revealing more details of this electric pickup truck.

First, Tesla's Certification Summary Information Report, submitted on November 21, 2023, mentions that the total voltage of the battery pack is 816 volts, and the battery energy capacity is 150 amps. And the specific energy of the battery is 170 watt-hours/kg.

This means that the Cybertruck has an energy capacity of 122.4 kWh, which is in line with the unconfirmed 123 kWh figure in some reports.

Unfortunately, Tesla did not disclose the battery capacity of the Cybertruck.

Tesla also filed an initial application for a certificate of conformity on November 11, 2023, which confirmed the existence of a heat pump.

This isn't surprising, as most new Tesla models are equipped with heat pumps, and spy photos shared by members of the Cybertruck Owners club earlier this year also show the cooling system located behind the front trunk.

In principle, the heat pump uses the heat generated by the battery and drive unit to heat the carriage, saving energy and improving driving range, which is especially critical in winter.

In addition, there is an interesting detail about Cybertruck charging.

The charging port is located on the rear left fender and displays different colors depending on the battery's state of charge (SoC).

For example, a continuous white light indicates that the charging cable can be plugged in and out. An orange light means that the charging cable is not locked properly, while a blue flashing light means that charging is proceeding as expected, and so on.

In the end, the Cybertruck has a reassembly mass of 6,898 pounds (about 3,132 kg), the all-wheel drive version weighs 6,669 pounds (about 3,028 kg), and both versions have a total vehicle weight rating (GVWR) of 9,169 pounds (about 4,163 kg).
