Integrated battery control system

摘要

An integrated battery control system incorporates a battery management system and a power control system to reliably and safely provide power to vehicles and other mobile devices. The integrated power control system incorporates safety features to protect the batteries from dropping below a threshold voltage or being overcharged, and from operating the vehicle when it is coupled with an AC power supply. An integrated power control system may be contained in a control enclosure having a computing device, battery power input, an AC power input, a power output switch, a power output, a key-switch interface and a shunt to measure current flow. The power control system regulates electrical power delivery to a drive motor and a pre-charge resistor as a function of the battery state of charge. When a battery unit is below a threshold value, power delivery is disabled to the drive motor and a pre-charge resistor.

1. An integrated battery control system comprising:
a. a battery management system comprising:
i. a computing device configured in a control enclosure and comprising:
an output data request port; andan input data port;wherein the computing device receives battery data from a battery unit monitoring module including the state of charge of two or more batteries in a battery pack; and b. the control enclosure comprising:
i. a power control system comprising:
a control circuit;a battery power input configured to provide a battery power supply to the integrated battery management system;a battery charger input;an output power connector,a power output switch;a key-switch input;a shunt; c. an interlock sensor configured to detect when a battery charger is connected to the integrated battery control system; whereby when said interlock sensor detects a battery charger connection, the power output switch opens, thereby preventing power supply to a drive motor of an electric vehicle through the output power connector;
whereby when a key-switch is detected through the key-switch input and when data received from the battery management system indicates that a battery unit is below a threshold value, the integrated battery control system disables the battery power supply to a drive motor and to a pre-charge resistor;whereby when a key-switch is detected through the key-switch interface and when data received from the battery management system indicates that all of said battery units are above a threshold value, the integrated battery control system enables the battery power supply to a pre-charge resistor for a pre-charge time and then enables power supply to a drive motor; andwhereby the battery power input is connected with a shunt to measure a power level provided from the battery pack coupled with the battery power input.
