Problems solved by technology

[0006] However, there are still known issues with panels
Typically, the temperature on the cooling surfaces across the plate is not uniform, causing some cells to rest on a different temperature than the cooling surface or surfaces against which other cells rest
This can lead to poor battery performance and / or shorter battery life as the batteries won't all be at equal voltage and therefore won't distribute the load equally

Abstract

A battery cooling plate includes a first plate and a second plate that are joined together at their respective edges, and are spaced apart to define a coolant volume therebetween. Turbulating insertscan be arranged side-by-side within the coolant volume and multiple rods can extend through the turbulating inserts to at least partially define flow barriers between coolant flow channels. A fluid manifold for the battery cooling plate includes a non-planar wall that extends along a length-wise direction of the fluid manifold to separate a fluid volume into a first portion and a second portion. Aseries of apertures are arranged along the length-wise direction and successive ones of the apertures are fluidly connected to the first portion and to the second portion in alternating sequence.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Patent Application No. 62 / 694,201, filed July 5, 2018, and U.S. Provisional Patent Application No. 62 / 735,236, filed September 24, 2018, each of the aforementioned U.S. Provisional Patents The entire content of the application is incorporated herein by reference. Background technique [0003] Vehicles such as passenger cars are increasingly electrified to replace or augment internal combustion engines. Such electric or hybrid electric vehicles use electric motors to at least partially provide the driving force for the wheels. The electrical power provided to the motor is usually provided by a large number of batteries installed in the vehicle. Due to the high power loads associated with vehicle transportation, the batteries from which this power is drawn experience significant heating during operation and charging. Batteries are known to be particularly sensitive to...
