Solar charging system^{* *}If equipped A system that provides power to the hybrid battery (traction battery) and auxiliary systems by performing solar charging via the large solar panel (solar roof) equipped on the vehicle roof. Even when a parking lot does not have charging equipment and in the event of a disaster, it is possible to charge^* the hybrid battery (traction battery) without any special operations as long as sunlight is available. ^*The charging amount via the solar charging system differs depending on conditions, such as season and weather. Solar charging system operation This system generates solar power with the solar panel equipped to the roof of the vehicle (solar roof). The hybrid battery (traction battery) is charged while parking. The electrical consumption of the hybrid battery (traction battery) is reduced during driving. The electrical consumption of the hybrid battery (traction battery) is suppressed increasing EV driving distance by supplementing power consumption for the auxiliary systems using solar power. Solar roof 12-volt battery Solar ECU Hybrid battery (traction battery) Displaying information related to the solar charging system Information related to the solar charging system can be checked on the multi-information display and Multimedia Display. (Energy monitor/consumption screen/solar charging information screen (if equipped)) Note: Solar charging system In the following cases, charging the hybrid battery (traction battery) via the solar charging system is not performed. The power switch is not off The “ Battery Heater” is operating (“Battery Heater”) AC charging has started The hybrid battery (traction battery) is fully charged The hybrid battery (traction battery) is completely discharged In the following cases, the solar charging system stops solar power generation and power supply to the hybrid battery (traction battery) and auxiliary systems. The temperature preservation function of the solar charging system operates There is a malfunction in the solar charging system When the temperature of the hybrid battery (traction battery) is approximately 23°F (-5°C) or less The amount of power generated by the solar roof differs according to the season, climate, weather conditions, vehicle angle and surrounding conditions. If even part of the solar roof is in the shade, there may be an extreme drop in power generation. Please adhere to the following in order to allow full performance of the solar roof. Clean the roof on a routine basis (Especially fallen leaves and bird droppings can lead to a substantial decrease in power generation) Remove snow from the roof as soon as possible Do not attach any seals or stickers to the roof It is recommended not to install a roof carrier etc. unless it is necessary. When the hybrid battery (traction battery) is fully charged, charging the battery via the solar charging system is not performed. When it is not necessary to perform charging from an external power source, charge the vehicle as much as possible using the solar charging system during the day and use the external power source only at night. As a result, the solar charging system can be used effectively. When the vehicle is left in the hot weather, the temperature preservation function of the solar charging system becomes easy to operate due to high temperature of the vehicle interior. Applying a glass coating to the solar roof may change the refractive index of light and reduce the amount of power generated. Small dots, lines, and stains may be visible inside the solar roof, however there is no problem with the power generation function or safety. Notice: To protect the solar charging system from damage Make sure to observe the following precautions. Do not modify the solar roof Do not condense sunlight onto the solar roof Do not place anything on top of the solar roof Do not subject the solar roof to strong impacts or apply force with sharp objects from the inside roof of the vehicle. If the solar roof is damaged, do not touch the damaged area and immediately request repairs from your Toyota dealer. If luggage is loaded on the roof If luggage is loaded on the roof (vehicles with solar charging system)
