COOLING SYSTEM IN A FUEL CELL ELECTRIC VEHICLE AND METHOD OF CONTROLLING A COOLING SYSTEM IN A FUEL CELL ELECTRIC VEHICLE
A cooling system in a fuel cell electric vehicle comprising a first chamber configured to contain relatively hot fluid and a second chamber configured to contain relatively cold fluid. The ratio of cooling power/fan power of a positive displacement device at a heat exchanger is monitored and thermal energy transfer between coolant and the chambers is controlled based on the ratio. When the ratio is above a pre-defined value or value range, thermal energy from the first chamber is provided to the coolant in the coolant circuit and passed into the heat exchanger, after which part of the thermal energy of cooled coolant leaving the heat exchanger is provided to and stored in the second chamber. The stored cold thermal energy is released from the second chamber when the ratio is below the pre-defined value or value range. The invention also relates to a method of controlling a cooling system.

Performing active interrogation of battery packs in situ to obtain precise SOC and SOH estimates
A characteristic, such as State Of Health (SOH) or State Of Charge (SOC), is estimated for an Energy Storage System (ESS) by supplying a pre-determined signal to the ESS, measuring a response signal output by the ESS, and obtaining an impedance spectrum of the ESS. In one example, the ESS is one of several electrochemical battery packs of an electric vehicle. The pre-determined signal is a current signal generated by a switching power converter that transfers charge from the battery pack to other battery packs or transfers charge from the other battery packs onto the battery pack. The pre-determined signal is generated without disrupting any load supplied by the battery packs. The battery pack outputs a voltage signal in response to receiving the pre-determined current signal. A processor obtains an impedance spectrum using the current and voltage signals, and thereby obtains an SOH and SOC estimate of the battery.
