  • In April, her 23-year-old son, Connor Lopez, was riding his motorcycle in Elk Grove when an oncoming car made a left turn and collided with him.

    Lopez, a piano teacher, died in the roadway. The district attorney’s office charged the driver, Harjit Kaur, with misdemeanor vehicular manslaughter — alleging that her failure to yield to oncoming traffic caused the fatal crash, court records show.

    She said she was talking to police and one of the officers kept referring to the case as “low-level.” “She took my son’s life, but that’s how they’re seen — low-level,” Lyman said.

    It really highlights something someone commented on another post: that we all suppress the knowledge that we’re driving two-ton death boxes. Like, it’s easy to say “she just made a turn without checking carefully enough,” and hard to rectify that with “she killed someone, however unintentionally.”








  • A bit more technical detail from greencarreports. I was wondering if 800v charging necessarily implies anything about motor voltage, and apparently it’s “sometimes”.

    GM’s GMC Hummer EV, for instance, runs at 400 volts, and each layer of its dual-layer battery pack operates in some ways as an individual pack. In 400-volt charging, the packs are connected in parallel, but for 800-volt charging a switch allows them to be connected in series—like the cells in a long, multi-cell flashlight—to take advantage of the higher voltage.

    That 800-volt “trick” permits the Hummer EV pickup, with its 205-kwh battery pack, to charge at 350 kw and gain nearly 100 miles of range in 10 minutes—despite its 400-volt system and its inefficiency compared to other EVs.
