Latest Patents
One of Toyokawa's latest patents is a battery temperature raising device for hybrid vehicles. This device is designed to raise the temperature of a battery under specific conditions. In engine travelling mode, when the engine water temperature exceeds a specified cooling water temperature, a first battery circuit connects to the main circuit, allowing the battery temperature to increase using cooling water. In motor travelling mode, if the motor generator temperature is higher than the battery temperature, the first battery circuit and a heat exchanger flow path connect to the main circuit. This creates a closed circuit for cooling water circulation, raising the battery temperature through heat exchange with a refrigerant.
Another notable patent is a heat accumulation and dissipation device for internal combustion engines. This device includes a cooling circuit that circulates cooling water to cool the engine. It features a heat accumulator for storing cooling water and an exhaust heat recovery device that captures exhaust gas heat. Upon starting the engine, the cooling water from the heat accumulator is sent to the engine to dissipate heat effectively.
