BYD announced that its 150 kW DC depot fast chargers, envisioned for electric buses and trucks, have been certified by Underwriters Laboratory (UL).

According to the Chinese company, this is the highest power, "single-unit charger" ever certified by UL. It's great to know that the device was confirmed safe in independent tests.

The chargers are fitted with CCS Combo 1 plug (SAE J1772 Combo) so the charger can be used by all the CCS1 vehicles in the North America.

"The BYD UL-listed 150kW DC charger gained a full suite of safety certifications that cover the charger’s connection to a power source and the plugs, receptacles, and couplers that connect to a bus or truck. The certifications include UL 2202, the standard for Safety of Electric Vehicle (EV) Charging System Equipment for fast chargers, and UL 2594, the standard for Safety of Electric Vehicle Supply Equipment."

The chargers aren't the only side business for BYD, which is mostly known for electric cars, batteries, buses and trucks. Another product that is spreading in the U.S. seems to be battery energy storage (ESS).

Most recently, BYD announced a 300 MWh / 75 MW ESS that will be installed at the Canadian Solar's 100 MWac Mustang solar plant in Kings County, California.

An interesting thing is that the building block of the system is a 2.5 MWh "Cube Pro". It really reminds us of Tesla's 3 MWh Megapacks, which indirectly confirms that the energy storage market drifts towards huge prefabricated MWh-blocks - basically the biggest size a truck can easily take.

"For the Mustang project, BYD will utilize Cube Pro, the latest generation energy storage solution designed for larger utility-scale projects. At 2.5 MWh per unit, the Cube Pro has a new liquid-cool battery system in the enclosure, with an energy density increase of 80% compared to the previous generation that used customized shipping containers as the enclosure."
