Abstract

The present disclosure is directed to energy storage systems for vehicles. In some aspects, the energy storage system may be used to power an electric automobile. The energy storage system may include a plurality of individual battery cells. The cells may be cylindrical and have a positive and negative terminal on the same side. The cells may be physically and/or electrically organized into bricks. The bricks may be physically and/or electrically organized into modules. The modules may be physically and/or electrically organized into strings. The strings may be physically and/or electrically organized into a pack. In some embodiments, packs, strings, modules and/or bricks may include flexible circuitry and/or may be liquid cooled.

First claim

What is claimed is:

1. A battery housing comprising:
a housing configured to surround at least one battery, the housing having a first side and a second side opposite to the first side;
a first retainer spaced away from the first side by a first gap, the first retainer having at least one opening therethrough, the first retainer configured to contact a first surface of a battery disposed within the housing;
a second retainer spaced away from the second side by a second gap, the second retainer having a at least one opening therethrough, the second retainer configured to contact a second surface of the battery that is opposite to the first surface;
an inlet configured to deliver liquid coolant into the first gap;
an outlet configured to receive fluid from the second gap, such that a pressurized fluid is capable of entering the inlet and into the first gap, passes through the at least one opening in the first retainer, contacts the battery, passes through the at least one opening in the second retainer, enters the second gap, and exits the outlet to regulate the temperature of the battery; and
a plurality of module monitor boards placed in a slot integral to the housing, each of the plurality of module monitor boards receiving battery module telemetry data from a corresponding battery module of the battery.

2. The housing of claim 1 , further comprising a first fluid path in fluid communication with the inlet, the first fluid flow path disposed within at least one wall of the housing.

3. The housing of claim 2 , further comprising a second fluid path in fluid communication with the outlet, the second fluid flow path disposed within at least one wall of the housing.

4. The housing of claim 3 , wherein the first fluid path and the second fluid path are disposed within walls that are on opposite sides of the housing.

5. The housing of claim 4 , further comprising a plurality of cylindrical batteries disposed within the housing.

6. The housing of claim 5 , further comprising a circuit disposed within the first or second gap, the circuit configured to electrically connect the plurality of cylindrical batteries.
