To charge a battery, the vehicle is connected to the EVSE. In some cases, the battery is unable to energize power buses. For example, if the battery is too cold and has insufficient charge, then the battery will not energize the power buses. If the battery cannot energize the power buses, then a precharge mode is enabled. During the precharge mode, charge is pumped onto two power buses until a setpoint voltage is reached. For example, a precharge circuit pumps charge onto one power bus and a power converter pumps charge from that bus onto a second bus. Once the setpoint voltage is reached, a current source charger is enabled, and energy stored on both buses is used to facilitate the turn-on of the charger, the precharge mode is disabled, and the EVSE charges the battery."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electric vehicle with precharge mode","description":"A system comprises an EVSE and an electric vehicle having a precharge mode.
