Title: Innovations by Lawrence Ziehr
Introduction
Lawrence Ziehr is an accomplished inventor based in Holland, OH (US), known for his contributions to the field of automotive technology. He holds a total of 6 patents, showcasing his innovative spirit and dedication to enhancing vehicle efficiency and performance.
Latest Patents
One of Ziehr's latest inventions is a system for cooling electric vehicle batteries. This invention provides a battery cooling system designed to cool an electric vehicle battery pack, thereby extending the operating range of an automotive heat pump system. The system effectively transfers waste heat from the battery pack to a secondary coolant system, which cools the battery pack. A secondary heat exchanger is coupled between the secondary cooling system and a reversible HVAC system, allowing the heat energy to be transferred to the HVAC system. This innovation reduces the need for supplemental electric heating, ultimately increasing the energy efficiency of electric vehicles.
Another significant patent by Ziehr is a controller for heating in reversible air conditioning and heat pump HVAC systems. This reversible HVAC system is designed to heat the passenger compartment of a motor vehicle. It includes a heat pump and an electric heater that supplies heat directly to the air blown into the passenger compartment. The controller initially selects the heat pump to provide heat and attempts to reach a target temperature for a predetermined period. It stores a heat pump gain value representing the heating capacity of the heat pump before switching to the electric heater. The controller continuously modifies the heat pump gain value to reflect changes in ambient temperature, ensuring optimal heating efficiency.
